Description

Large containers for pourable, pasty and slurry-like materials and methods of use for the same

The invention relates to a large container for holding pourable, pasty and sludge-like materials, which essentially has the shape of an upright cylinder, and to methods in which these containers can be used.

Large containers for the materials mentioned have primarily concrete walls or steel walls; other materials are also conceivable here, e.g. Plastic walls. The disadvantage of all these containers, however, is that the costs are relatively high. This may not be a problem if the material is of high quality or e.g. is flammable. The possible uses of such previously known containers are therefore limited.

Another disadvantage is that no liquid can escape through the walls. It is therefore not possible to store sludge or silt for draining the same in such containers. Rather, the procedure is such that the silt is first deposited behind sand dams and the like, where it can drain off. This usually takes a long time, because in humid regions there is always new water coming from above in the form of rain. After sufficient drainage, the silt can then be moved to another location for final landfill, which requires a considerable amount of work. In a large container of the type mentioned at the beginning (DD-PS 93511), textile material is provided as a component of the wall material. However, this container is still very complex, since it requires special stabilizing rings for absorbing the large ring tensile forces of the filled container and permanent support structures. These stabilizing rings and support structures cannot be removed after the container has been filled, otherwise the container will no longer be stable. Since it contradicts the recognized rules of architecture to install additional bulky, rot-proof objects such as masts, steel cables etc. in landfills and these parts are very expensive, the container can only be used in special cases.

Another previously known container (DD-PS 84 588) also requires permanent support structures and also an ial fabric. Finally, as can be seen from the figures, this container is obviously only intended to be a relatively small container, but not a large container.

The object of the invention is to create a simply constructed large container which is inexpensive and can be used for purposes for which large containers have not previously been used, which in particular for the more cost-effective and space-saving processing of sludge and silt Landfills or for use in pouring concrete.

The solution according to the invention consists in that the side wall consists of textile material which is reinforced with fabric reinforcements which are arranged diagonally to the directions of the weft and warp. The side wall of the container according to the invention thus consists exclusively of textile material. Any kind of stabilizing rings or the like are not required. Permanent support structures are also not required, which at most only have to be used partially during the filling of the container, but can be dismantled when the container is completely filled.

The invention creates a large container for the first time, the walls of which consist exclusively of textile material. This overcomes the prejudice that walls consisting solely of textile material cannot withstand the forces occurring in a large container. The fact that this is possible is essentially achieved by the fabric reinforcements arranged diagonally to the directions of the weft and warp, through which the container can no longer warp asymmetrically. Until now, complex permanent support structures had to be provided in order to avoid these possibilities and problems.

Stable textile materials suitable for the container according to the invention are, for example, the geotextiles which serve to stabilize floor structures. So far, however, these geotextiles have normally been laid out more or less flatly so as to form a reinforcement of the soil, firmly embedded in the soil. It is the merit of the invention to have recognized for the first time that upright large containers can also be created using this textile material. The invention overcomes the prejudice that this material is not suitable for walls of large containers due to the considerable forces that occur.

In particular, textile fabrics can be used as the textile material. The invention has recognized that the finished container, with its filling, requires no further supports apart from the textile material; The content of the textile material is kept in the container shape. So the container is very cheap. Advantageously, however, the textile material is suspended from a support structure before it is completely filled, since this is the only way to obtain appropriately large containers.

Since the side walls made of textile material are arranged essentially upright, a particularly large amount of material can be stored in a small space in the large containers. In many cases, however, at least some walls will be provided which are not upright but are arranged at an angle. If, for example, you want to pour a dam, a dyke or the like from concrete, which must be chamfered at least on one side so that the waves can run out here, the appropriate formwork for pouring the concrete can be formed with the help of the large container according to the invention with textile walls, the front textile wall then has the desired inclination of the front surface of the dam or dyke. Of course, a rear surface of the dam or dyke can also be inclined, although more or less upright walls will often be used here to save space.

In particular in order to form such a dam or dyke, the container can be constructed from a plurality of sections, the side wall made of textile material having a plurality of regions which form part surfaces of cylinder jackets. Mud landfills can also be built in this way. A particularly simple container is characterized in that it is essentially circular cylindrical. Of course, you can also set up such containers next to each other.

With large circular cylindrical containers, the support structure can be removed when the container is filled and the material introduced therein has settled. For this purpose, the support structure advantageously has dismantled steel poles and steel cables. The steel masts and steel cables dismantled in this way can then be used cost-effectively for the construction of a new container. However, the textile material remains in place. If several containers have been arranged next to one another for a landfill and the spaces between containers have also been filled with the material to be deposited, the textile material remaining in the deposited material serves the purpose of permanent soil stabilization or of the deposited material.

With the support structure, not only the upper edge of the possibly relatively large textiles must be held in place when the container is empty, but also the lower edge, so that the construction remains stable in the assembled state before filling, even in wind. After the container has been filled, the textile material no longer needs to be held in the lower region. If one now provides that the steel masts in the lower region are provided with downward-pointing thorns, hooks or the like for holding edge parts of the container, then when the steel masts are driven into the ground, the thorns, hooks or the like become the textile material here hold tight. When the steel masts are pulled out after the container has been filled, the mandrel, hook or the like releases the textile material; it is therefore not necessary to dig out the textile material in the edge region and to loosen the connection laboriously. In an advantageous embodiment, in addition to the steel cables and steel masts as a supporting structure or instead of these steel cables and steel masts as a supporting element, hollow bodies with flexible walls that can be filled with pressurized fluid are provided. In particular, the hollow bodies can be hose sections which are essentially perpendicular and closed at the ends. If these initially flaccid hose sections are filled with pressurized fluid (for example water or compressed air), they form more or less rigid supports which hold the container wall up until the container is filled.

If the hollow bodies in zigzag form are diagonally arranged to the weft and chain and are closed at the ends of hose sections, a further increase in stability is obtained. '

In particular, the hollow body or tube sections can be provided on the inside of the textile side wall. In this case the following advantageous effect can also be achieved.

If the hose sections are filled with relatively little pressure fluid, so that they are initially more or less limp and the container is held up by other means, the pressure fluid is pressed out of the lower parts of the hose section as the container is gradually filled and thus expands the upper part of the hose sections and stiffen them. The upper edge of a partially filled container is thus well supported. In the case of mud landfills, the remaining support structures could then be removed after the container had been filled once. If the filling level drops as a result of partial dewatering of the sludge, the upper part of the edge, which is now exposed, does not collapse, but remains stand upright so that more sludge can be refilled at any time, depending on the drop in the surface of the sludge already filled.

Any type of support structure with which the entire container has to be clamped before filling is not only complex and expensive, but also has to be dimensioned in a stable manner. This is less necessary to keep the relatively low weight of the textile wall, but in order to be able to withstand considerable wind pressures in the assembled state before filling in the event of a storm. All of these problems can be eliminated, in particular when filling with rinse goods, and a substantial reduction in cost and simplification can be achieved if the upper side of the side wall is provided with buoyancy bodies.

In this case, the container, which has been prepared in the factory, is placed flat with its bottom part on the correspondingly prepared base. The textile wall is folded accordingly, placed on the floor from the edge of the floor towards the center, so that a corresponding opening remains in the center, at the edge of which the buoyancy bodies are provided, which are connected to the upper edge of the side wall . If you fill in the rinsing material, "the buoyancy bodies lift off the floor and, as the degree of filling increases, span the wall more and more. It can also be provided that the side wall itself is designed to float (for example by appropriate treatment of the fabric or inclusion or attachment of air cushion mats and the like).

This construction with the buoyancy bodies is not only very simple, it also does not require any assembly personnel for masts, wire ropes and the like on site. Even the wind pressure is no longer a problem, since the - Ö -

Container is only exposed to winds to the extent that it is already upright as a result of filling. The corresponding part of the container will, however, be sufficiently held against the wind by the filled material.

If large amounts of material are piled up, there is a risk that the substrate will be pushed out laterally under the container (basic breakage). This is avoided if the floor consists of a textile mat that is connected to the cylindrical wall at its edge. This textile mat has essentially similar functions to the known geotextiles; it should transfer the pressure of an overlying layer of material in a suitable manner to the base.

As a result of the hydrostatic pressure rising from top to bottom and a resilience typical of the material, which is shown by all textiles, the container will have a slightly larger diameter in the lower area than it originally had and will also maintain in the upper area. So here, in the base region mat the connection between Bodenarmierungs¬ and side wall is not destroyed, it is advantageously provided that seams are provided near the binding site Ver¬ mat- and expansion folds _w ith target tear. - -

The diameter, which decreases from bottom to top, has the further advantage that the horizontal hydrostatic and earth pressure forces of the filled material have an upward component, through which the wall material is also pressed upwards. In this case, the corresponding lifting of the wall material is not effected solely by the buoyancy elements.

Advantageously, the wall is at least partially multi-layer, in particular wound, and has more textile layers in the lower area than in the upper area. This embodiment also takes into account the fact that the hydrostatic pressure of the stored material is greater at the bottom, which also leads to a greater tensile force on the textile material. In this way, the graded thickness of the container wall corresponds to the forces that occur. However, one or more layers of a material can also be used, the thickness of which increases from top to bottom, for example by the thickness of the warp threads increasing accordingly. In this case

- 10 -

the thickness of the container increases more or less continuously from top to bottom and thus better corresponds to the tensile force, which also continuously increases from top to bottom.

The support structure can be arranged outside the container. However, it can also be provided that the container has a central support to which, for example, a tent-like roof can be attached. This roof can prevent the material from getting wet due to rain, which can be particularly important when the sludge is to be dried. If, however, the sludge is filled from above in the middle of the container, for example, it will have a slightly sloping surface towards the edge of the container, which is further promoted by the fact that the sludge level in the edge area drops more quickly due to drainage through the textile material. A part of the rainwater runs off on this "natural roof", so that it may be possible to do without the tent-like roof, which of course simplifies the construction.

In a preferred embodiment, the container is double-walled with an intermediate space for material absorption between the walls. For example, concrete rings and the like can thus be produced if the container is first filled with concrete up to the inner wall with sand, for example, and then between the inner wall and the outer wall with concrete. After the concrete has set, the sand is then removed from the inner container. But not only concrete rings can be made with this container. One could also provide a (in this case relatively small) concentric inner container within a larger container, the walls of which are of course also made of textile material and which is filled with gravel, for example. In this case, the dewatering of the sludge could be made much easier, since the water can run off not only on the outside but also in the middle. This inner, relatively small container can best be held by a central support on which a ring is suspended from which the textile material hangs in a cylindrical shape.

Reinforcements connection of the various fabric layers, if several are superposed, or the tissue wall with the tissue _¬ can be prepared in various ways. One could, for example, hold the fabric between plates with the aid of rivets, the rivets being pushed through the textile material with careful displacement of the individual threads so that no threads break. These rivets provide a particularly high tensile strength Verbin _¬-making in some places.

The rivet connection is further improved if the fabric layers or textile layers lying one above the other are soaked with an adhesive, PES casting resin or the like before riveting. The layers soaked are then between

16 the plates pressed together, which are then riveted together. In this way, a particularly secure and high-tensile connection is obtained which transmits all the forces occurring in the textile layers to one another.

Alternatively or in addition, the fabric layers and / or fabric reinforcements can also be sewn,

Gluing, welding or possibly combinations of these processes are connected to one another,

A cylindrical container with a diameter between 10 and 50 m, in particular between 20 and 30 m, is particularly advantageous, in particular for sludge dewatering. In an advantageous embodiment, the height of the container is between 2 and 8 m, in particular between 4 and 6 m.

In an advantageous method for depositing silt, mud and the like, the silt, mud or the like is poured into one or more containers in the form of upright cylinders with textile walls and refilled several times after the surface has sunk as a result of dewatering, and then subsequently the support structure is removed, if one was used at all.

It is advantageous to arrange several containers next to one another so that a dam is formed, the front side of which is provided with a continuous slope after the sludge has been dewatered; the further silt or mud is then stored behind this dam. Instead of a plurality of cylindrical containers standing next to one another, one or more containers can also be used which are constructed from several sections, the side wall made of textile material having several regions which form partial surfaces of cylinder jackets.

The main advantage of the invention is that a lot of material can be stored in a very small space in an economical manner; This is achieved in that after dewatering a layer formed as described, at least one further layer with containers and mud / silt is built up on the first.

However, the method according to the invention is also suitable for pouring concrete. In an advantageous embodiment for building dams, walls and the like, in which concrete is poured into a mold and solidifies there, it is provided according to the invention that textile walls in the form described are used. The water permeability of the textile walls can be controlled as required by selecting or treating the textile material.

Embodiment of a container.

As shown in FIGS. 1 and 2, a plurality of containers are built on the floor 1 on a surface which is delimited by a protective wall 2 and a trench 3. The containers consist of circular cylindrical angeordne¬ th webs of textiles, in particular ^'fabrics 4 which are spanned by corresponding support structures. These support structures have masts 6, ground anchors 7 and 8 wire ropes.

- 16 -

ie as shown in Fig. 3, the textile material is partially multi-layered. In the uppermost part, only one material layer 5a is provided, on which the reinforcement shown in FIG. 4 by textile strips 9 is only provided diagonally to the warp and weft for better reinforcement of the fabric. Another layer of the same or a similar material 5b is applied to the bottom two thirds of the textile web; the connection is made by riveting, welding, gluing or the like. This textile web 5b is laid down below to form a tubular bead 10 and ^{* led up} again, where it forms the third layer at 5c in the bottom third. The bead 10 can be filled with sand, for example, in order to hold the textile fabric on the ground. Between the layer 5a, which extends all the way to the floor, and the layer 5b, a further textile layer 11 is inserted at the edge area, which forms a floor reinforcement mat.

Since the container will expand more in the radial direction in the lower area than in the upper area as a result of the hydrostatic pressure, the floor mat 11 ^' in the edge area has expansion folds with predetermined tear seams, which is designated by (B) at 12.

In the embodiment shown in Fig. 3, the outermost textile layer is the one that goes from the top to the bottom. Favorable load conditions are obtained, however, if the innermost textile layer is the one that runs from top to bottom, that is to say the additional layers in the lower area are applied externally, since the horizontal connecting seams between the individual layers are much less due to the hydrostatic internal pressure ¬ be claimed. This is shown schematically in FIG. 4, in which the individual textile layers are also built up from a single textile blank 5, which is step-like. The cut is shown at (A); at (B) the finished wall. This wall is expediently already manufactured and sewn, riveted and the like in a factory hall or the like, since this is very difficult or not possible at the construction site because of the wind prevailing there. 4 also shows that the individual layers overlap at 35. With these overlaps 35, they can be connected to one another particularly well by riveting and the like over a large area, so that the risk of cracking can be avoided. These overlaps can also be seen in single-layer textile walls. FIG. 5 shows the textile reinforcement 9 already mentioned, which can be fastened to the textile web 5 at 13 with rivets arranged at intervals, for example. The textile materials can be held together by metal plates in order to distribute the forces over a larger area. In addition, the reinforcement fabric can still be sewn on or fastened in some other way, as indicated by the dashed line.

6 shows a detail on the support piles 6, namely a downwardly directed hook 14 which engages in a corresponding loop, a fastening rope 15 or the like for textile wall 5 and floor reinforcement mat 11. This ensures that the container remains stable against wind influences even before the material is filled. If the support structure is subsequently removed after the container has been filled, and thus the support post is also pulled out, the hook 14 is automatically released from the fastening rope or the like 15, so that the connection does not have to be separated at great expense.

FIGS. 7 to 9 show the containers of FIGS. 1 and 2 after the filled material 16 has settled. In this case, as shown in the figures, the support structures could be removed. The material cylinders arranged next to one another in this way are now provided with an embankment by means of, for example, bulldozers at 17, in that the part 17 shown in dashed lines in FIG. 7 is displaced to the side in order to fill up the space between adjacent material cylinders 16 . To this _.wecκ you will first have to cut the textile material along the dashed line on the cylinder wall. In this way, a dam is obtained which has a continuous slope 18 on one side. On the other hand, further sludge can then be introduced behind the dam, which can also drain here. After such a dewatered material layer has been produced (in an advantageous embodiment at a height of 5 m), the method can be started again on the newly formed floor surface, so that several layers of the material can be deposited one above the other.

In Fig. 10 is shown in cross section from above the case that two containers according to the invention are arranged concentrically to each other. In addition to its outer wall 5, the container also has an inner wall 25. The inner container thus formed within the wall 25 can be filled with sand ^' or gravel 19, for example. Then 20 concrete can be filled. After the concrete has set, the concrete rings 20 shown in FIG. 11 are obtained after the sand 19 has been removed from the interior of the concrete rings.

12 shows a particularly simple type of container with its textile wall 25, which is also filled with gravel 19. For this purpose, the textile wall 25 was suspended from a center post 21 with the aid of wire ropes 8 and a ring 22. After the gravel 19 has been filled in, the sludge or silt can be introduced between the wall 25 and the outer container wall 5, which can then not only drain outwards through the textile material, but also inwards through the gravel material 19 . FIG. 13 shows another type of container according to the invention, which consists of several sections 36. These sections 36 correspond to juxtaposed cylinders. The width of the sections 36 can be approximately half as large as the diameter of the cylinder.

As can be seen from FIG. 13 (at (B) is a plan view, at (A) a section along the line AA is shown), a textile web 5 is arranged between support posts 6. After filling, the textile web 5 will press outward between two adjacent support posts 6, so that the shape shown in the figure is adopted, whereby this shape can of course already be prepared by the suspension wires 8. Normally after the filling, the support piles 6 will have to remain, unless one arranges several such containers next to one another and also fills the interstices with material. Of course, the support pillars also do not have to stop when the container is filled with concrete, for example to produce a dam. In this case, the pillars 6 and the rest of the support structure could be removed after the concrete has hardened. The textile material then disintegrates more or less automatically depending on the material selected due to the chemical effect of the concrete or sunlight. 14 shows another embodiment of a container according to the invention in the unfilled state. The container is simply placed flat on the base 1 prepared accordingly, its base 11 resting on this base 1. The side wall 5 is folded inwards so that it forms an outer ring area on the bottom 11. The resulting folds are fixed, for example, by predetermined breaking seams. At the inner edge (after filling the upper edge), the side wall 5 is provided with buoyancy bodies 26 which, in this embodiment, have a cylindrical shape.

If the container is now filled, the buoyancy bodies 26 float on the filling material and gradually erect the side wall 5, as is shown in FIG. 15 progressively from A to E with increasing filling level. The side walls 5 are stretched; the previously planned folds open by destroying the predetermined breaking seams. In addition, the buoyancy bodies 26 move away from one another with increasing circumference of their circular line on which they are arranged. The predetermined breaking seam 12 at the bottom also opens gradually, so that the container gradually becomes larger in diameter as the filling level increases, as is also shown in FIG. 15.

As shown in FIG. 16 on the left, the buoyancy bodies 26 can be held in place by textile straps 27 or the like, which can then be opened after the container has been filled, so that the floating bodies 26 can be removed and reused at another location. However, one could also sew the buoyancy bodies directly into the side wall 5 and also make the entire side wall floatable, for example by inserting or applying appropriate air cushion mats therein. In the middle, a tubular element 28 is shown in FIG. 16, which can be arranged vertically and can be provided instead of or in addition to the floating bodies 26 (in each case between two floating bodies 26). If this tubular element 28 is filled with compressed air or pressurized water or another fluid, it forms a support structure for holding the wall until the container is filled.

Such a tubular element 28 is shown on the right in FIG. 16, which was only partially filled with fluid, in particular a liquid, so that it is initially limp. As the degree of filling through the material 16 increases, the water or the other fluid is compressed in the lower region of the hose 28, so that the hose is expanded above the filling mass 16 and thereby becomes more or less rigid, so that it is the side wall here 5 can span as a support structure in the upper edge area.

Calculations by the inventor show that the container according to the invention and the method according to the invention very advantageously enable the storage and drying of sludge or silt. If you first fill the tank with silt and then fill in silt (at ever shorter intervals), if the level has dropped due to drainage, you can achieve much faster than before that the original one Schlick essentially only occupies a third of its volume and completely fills the container. Taking into account the fact that the silt can also be brought to higher landfill heights completely without risk, there is a considerable reduction in the space requirement compared to the previously known methods as a result of the continuing pre-drying required on large-area landfills. In addition, decisive costs are saved since the silt can remain after drying; it does not have to be brought to another site for final storage after drying.

As has already been mentioned several times, containers and methods according to the invention can also be used for pouring concrete. The fact that textiles with very different water permeability are available so that the setting of the concrete can be controlled specifically can be used. There are in fact absolutely water-impermeable textiles (for example coated with rubber) and very water-permeable textiles. The watertightness can be increased, for example, by using nonwovens.
