Definitions

  • the present invention relates to new cellular structures for the realization retaining walls according to claims 1 and 2 and to methods of erecting a retaining wall according to claims 15, 16 and 17.
  • the present invention aims to put to a new realization of structures cellphones for retaining walls that use materials existing on the market.
  • the present invention also aims to develop a cellular structure which is very simple as much in terms of manufacture of the structural elements constituting it that at the level of its implementation.
  • the present invention also aims to develop a cellular structure economic.
  • the present invention also aims to develop a cellular structure whose facing can be built with different elements of finish.
  • a form of advantageous embodiment of the invention provides a cell structure supporting an embankment which includes a substantially facing structure vertical and a pair of built-in structures in substantially vertical lattices.
  • Each mounting structure is suitable for mounting to a respective vertical edge of the structure of facing.
  • the facing structure is adapted to to define a facade of the cellular structure.
  • the installation structures are adapted to extend into the embankment.
  • Another advantageous embodiment of the invention provides a cellular structure of embankment support which includes a structure of substantially vertical facing and a structure mounting formed of at least one bracket.
  • Stirrup is adapted to connect each of its two ends at a respective vertical ledge of the facing structure.
  • the stirrup forms a structure in "U" shape adapted to extend so substantially horizontal in the embankment.
  • the facing structure is adapted to define a facade of the cellular structure.
  • Another advantageous embodiment of the invention provides a cellular structure rigid backfill support that includes at least a concrete foundation element and an element of precast concrete facing suitable for fixing substantially vertically to the element of foundation using first means of connection.
  • a pair of concrete inserts prefabricated are adapted to be fixed so substantially vertical to the foundation element at using second connection means.
  • cellular structures for retaining walls include basic structural elements which are metallic or synthetic mesh.
  • the trellis can be combined with sheet metal elements, cables or precast concrete. The juxtaposition and the backfill of these cellular structures form retaining walls.
  • the two basic elements of a structure cell are the facing elements and the mounting elements.
  • the cells in "U" shape are open towards the massifs with the trellis facing 1 and embedding in trellis 2.
  • Cells can also be made fictitiously closed, consisting of facing in trellis 1 and stirrup recesses 3 (figure 2).
  • the facings can consist of bars or independent metal dishes or even cables. All these facing elements can be put in combination with precast concrete elements. Also, cells with block facing architectural concrete of small or large dimensions can be done.
  • these types of structures can be defined as massifs composites, monolithic, produced by the interdependence between an earth massif and a structure.
  • FIG. 1 The structure illustrated in Figure 1 is executed by the juxtaposition of cells in continuous trellis panels, or in elements independent of facing and embedding in lattice 1 and 2. In the latter case, the elements independent are assembled with rods 4.
  • this facade covering is represented by applying shotcrete 6.
  • This coating can be aesthetic or of resistance.
  • the facade cladding is consisting of masonry in concrete blocks architectural or dressed stone 7. These blocks of concrete can be the ones we use for building facades or they can be designed specially for retaining walls.
  • the masonry is reinforced and linked to the structure of facing 1.
  • the space between the masonry on facade 7 and the cell structure can be filled with concrete 8.
  • this type structure allows insertion into the facing small elements in precast concrete.
  • Concrete blocks for facing are designed to these ends and the erection of facings is carried out according to principles of dry masonry ( Figure 7).
  • the horizontal reinforcement of the facing 9 can be made in round bars or flat metallic.
  • Figures 7 and 7a illustrate the use of metal dishes.
  • the frame vertical 10 can be made in round bars or pipes.
  • the precast concrete blocks 11 are designed for these purposes.
  • the facings produced can thus have the desired aesthetic.
  • Optional neoprene type seals 12 can be used when the cell structure is subject to significant stress.
  • Figures 8 and 9 illustrate cell structures of the same type as those described respectively in Figures 1 and 2 but in which the facing structure is designed to receive large flat panels.
  • the horizontal bars of the facing 13 have a broken geometry that develops from a rod assembly 4 to another. The changes of direction of the horizontal bars 13 take place at level of vertical bars 14. Cables can replace horizontal bars 13.
  • Figures 10 and 11 illustrate the cellular structures described in Figures 8 and 9 additionally comprising precast concrete panels large dimensions 15 which have been inserted into the facade.
  • the precast concrete panels 15 are characterized by the fact that two of their dimensions (width and height) are large compared to the third (depth). These panels 15 are designed to resist the push of the land.
  • the signs 15 are also designed to be able to assemble with lattice recesses 2 or in stirrups 3.
  • This type of structure composite is that a flat facing is obtained while preserving the cell principle open or fictitiously closed towards the premise at support.
  • Figure 12 illustrates the details of structures described in Figures 8 to 11.
  • the horizontal reinforcements of the facing are bars round or cables 13.
  • Vertical bars 14 are perforated pipes or not.
  • Type bands neoprene 16 are provided for horizontal joints ( Figure 12a).
  • This type of structure is thus carried out dry with neoprene seals and as studs assembly, perforated pipes or not.
  • pipe studs allows the retransmission of cable stresses to concrete studs and studs on larger surfaces great.
  • Perforated pipe studs allow, after the execution of the work, to carry out injections in order to achieve the monolithism of the facing.
  • Pipe studs also allow carry out post-tensioning of the facade if desired. Also, cables housed inside the pipes can extend to the foundation so that can then be post-tensioned.
  • Figures 13 and 14 illustrate cellular structures having recesses in trellis 2 or in stirrups 3 characterized by facings in precast concrete elements 17 mounted openwork.
  • the facing can also be made of wooden planks.
  • the assembly elements are bars or pipes 18. Post-tensioned or not, these elements 18 also allow cables to be accommodated of post-tension and also the realization of injection. In the overlapping area of concrete elements prefabricated 17, i.e. at the ends of these last, we can have one or more elements assembly 18.
  • This type of cell structure can be backfilled with stone of appropriate dimensions or with soil.
  • the voids in the facade are filled with sheet metal, asbestos-cement, geotextile, etc.
  • the precast concrete element 17 of form parallelepiped is characterized in that its dimensions in its cross section are small relative to its length. Opposite faces can be parallel or not. These are designed to take back the thrust of the land, to be able to assemble with the recesses in trellis 2 or in stirrups 3 and to make columns on the area of their overlap.
  • Figure 29 illustrates the use of openwork cell structures such as described above for the realization of the walls of support 43.
  • the openings have not been sealed so as to allow the vegetation to grow across the facade of retaining walls 43.
  • Figure 30 illustrates a wall 44 of support in its lower part and elevation in its upper part on two sides.
  • the wall in elevation primarily serves as a noise barrier; it is why all of its openings were closed.
  • Figures 15 to 17 illustrate cellular structures with facing in panels of concrete, small or medium-sized. The same principles of the cellular structures described previously are respected.
  • Figure 15 illustrates a cellular structure with recessing in stirrups 3, although lattice recesses can also be used, and concrete blocks architectural of small or medium dimensions 20.
  • Architectural concrete blocks 20 or blocks in cut stone are masonry using rods vertical or studs 19. These rods 19 have a part a role of resistance and, on the other hand, a role of connection between the facing and the recesses.
  • the recesses in stirrups 3 are housed in the vertical joints (figure 16) or in the horizontal joints (figure 17).
  • the stirrup recesses are made in metallic or synthetic dishes (figure 16) or in round or square bars (Figure 17).
  • Figure 17 where the recesses 3 are housed in horizontal joints, type joints neoprene 12, similar to those of structures cell phones with integrated coating (Figure 7), are planned.
  • the structures described below are retaining walls made of reinforced concrete elements prefabricated, large, assembled by post-tension in a mud trench or in water, so as to achieve a rigid cellular structure in the shape of a "U" (fig. 18 to 25) using the same theoretical principles as those of the structures described before.
  • the assembly elements shown generally by perforated pipes or not, are used guide for mounting and ultimately can be tensioned directly or through tie rods anchored in the foundation.
  • the same pipes can be used to inject mortar.
  • Rigid cell structures are made up of facings which are elements which resume the stresses due to the push of the earth and water.
  • the recesses are elements which take up the requests of siding and other structures for forward to the foundation.
  • the assemblies are perforated or non-perforated pipes of appropriate dimensions having the multiple functions described below. Concrete poured on site serves as a foundation on the one hand and completes the structure on the other hand.
  • the foundation elements 23 which are then set up include holes 24 provided for pouring concrete under the foundation elements 23.
  • Foundation elements 23 are an integral part of the recesses and are positioned at the planned depth on a layer of concrete.
  • the pouring of the foundation concrete can precede the installation of the prefabricated elements or concrete can be poured through holes 24 planned for this operation.
  • Pipes 25 fixed to the elements of foundation 23 serve for guiding the elements prefabricated and then they are used for the post-tension and for injection.
  • the first built-in elements 26 descended along the guide elements 25 to their final position. Then follows the bet in place of the facing elements 27 (FIG. 20). The concrete 28 is then poured in place.
  • Neoprene bands can be provided to improve the tightness of the structure and also ensure better contact between seals horizontal.
  • the fresh concrete will be poured between the prefabricated elements and the earth, thus completing the structure.
  • FIGS 18 to 21 illustrate a dock infrastructure. These are structures rigid cell containing earth. The structure-soil interdependence is highlighted. This type of structure can be used for docks of all kinds, whether made using a trench of mud (figure 18), or directly in the water.
  • the facing elements are continuous in the sense of height while the recesses can be hollowed out to lighten the prefabricated and to get better monolithism with concrete poured in place or with the fill ( Figure 21).
  • the recesses can be realized in elements of metal frame and concrete poured in place.
  • Figures 22 to 25 illustrate a building infrastructure.
  • the erection stages are similar to those found in Figures 18 to 21. In this case, these are cellular structures rigid with cleared recesses. This structure will be used especially for the realization large buildings with multiple basements.
  • the prefabricated elements of facing and buttresses can have their height equal to the distance between floors (figure 25).
  • the buttress ends can be seating points for the columns of the building superstructure.
  • the elements of buttresses can be more or less hollowed out, depending on their degree of stress (figure 25).
  • the floors that are executed represent good horizontal bracing, results in an increase in stability.
  • Figure 22 illustrates a mud trench 29 with low walls guide 30 which are designed to house the structure rigid cell for basements buildings.
  • FIG 23 illustrates the installation of foundation elements 31 which include holes 34 in order to pour the concrete under the foundations. Of guide pipes 35 are fixed on the elements of foundation 31.
  • Figure 25 is an elevational view of mounting elements 32 over the height of a storey. It includes the floor 38 and the structure of a floor 39. Optionally, tie rods post-tension 37 are arranged inside the guide pipes 35.
  • Rigid cell structures can be made perfectly waterproof.
  • An advantage very important for the use of this type of structure resides in the total absence of tie rods anchor outside the boundary of the construction, what we find at the walls classics made in a mud trench.
  • Figures 26 to 28 Some practical examples of structures in rigid veil are illustrated in Figures 26 to 28.
  • Figure 26 illustrates a platform in deep water 40 using several of the structures rigid cells described in Figures 18 to 21.
  • Figures 27a and 27b illustrate an infrastructure of buildings 41 using cellular structures Figures 22 to 25.
  • Figures 28 and 28a illustrate the infrastructure of a building 42 (the large basements) located at the edge of the water.
  • the rigid cell structure is solicited by earth or water.
