Description

The present invention relates to an emergency raceway and its implementation method. The technical sector of the invention is that of the construction of tracks of a temporary nature to allow the circulation of vehicles on sites not provided with roads or suitable grounds.

Concerning more particularly the aviation and if the tactical needs of the last world wars could be satisfied with the rusticity and the economy occasioned by the use of runways of emergency take-off constituted by metallic plates connected between them, there n 'It is more the same nowadays because the military operations imply air fleets much more demanding as regards aeronautical infrastructures. This essential level of quality leads to the design of modular runways capable of meeting modern requirements, the great advantage of which is to enable them to accommodate all military or civil air traffic.

A rolling track for land or take-off vehicles, of rigid or flexible type, must meet two basic criteria:
- the material constituting the tread must be able to meet defined needs;
- the tread support must be able to withstand the service constraints.

Also, during the construction of the runway, the problems linked to climatological conditions such as freezing, thawing, drainage and water infiltration, sunshine, etc. must be taken into account.

Several types of flooring are known for producing in particular emergency runways. Unlike permanent structures, an emergency runway or take-off runway is designed to provide a service limited in time.

Among the known coatings we will quote for example:
- "flight plates" manufactured by ARBEL Industries, which consist of steel plates, stamped and ribbed;
- "the modular aerodrome for emergency situation" made from an aluminum box structure, made in France by the company PECHINEY. Similar structures are manufactured in GREAT BRITAIN and ITALY.
- aluminum or polypropylene / aluminum honeycomb sandwich structures manufactured in the UNITED STATES.

EP A 0134 352 (Kaiser) is also known, which relates to a rapidly deployable track or covering system for an assault vehicle comprising articulated panels. Said panels consist of a honeycomb structure located between two plates and patent FR A 2 602 253 (Lathoumetie) which relates to an improved device for connecting metal panels to an aerodrome area. The edges of the panels have a continuous groove and their assembly is obtained by means of cruciform keys engaged in said grooves.

All the above-mentioned structures have the drawback of being able to be used only on ground surfaces previously prepared by heavy earthmoving means.

In fact, the mechanical performance of the carpets produced with the aforementioned structures is closely linked to the preparation of the support soil.

The objective of the present invention is to produce, by means of appropriate devices, emergency taxiways for land vehicles, or take-off for aerial devices, on all types of soil. For runways, however, the gradients of the selected terrains must remain compatible with aeronautical standards.

Furthermore, as it is important that rapid repairs can be carried out, the modular concept for the assembly of such tracks remains essential. Important factors such as the size and lightness of modular coatings are also taken into account for the implementation of the invention.

This objective is achieved by the emergency track according to the invention, comprising a plurality of covering panels assembled together by removable joining means fixed to their lateral sides, each panel consisting of at least one upper plate. bearing and a bottom plate and a structure to cells which connects said upper and bottom plates, characterized in that said panels are made integral with the ground on which they rest by means of anchors comprising an articulated rod at the free end of which are mounted elastic means associated with means clamping in order to carry out a prestressing of the ground, in that said panels comprise housings extending from the upper plate to the bottom plate which housings are open at the level of said upper plate and are adapted to receive said elastic means and said clamping means in order to integrate them into the panels, in that the bottom of said housings has an opening for the passage and placement of the anchors, when the panels are fixed and in that said housings include a plug-in plug in their open part to close them after having disposed said anchors, which plug being located substantially in the plane of the upper plate of the panels.

In one embodiment, said panels comprise two superimposed upper plates, in contact with one another. Said housings which adopt the shape of a cup have a peripheral rim at their upper part, which rim is inserted between said upper plates of the panels and the bottom of said housings is applied against the bottom plate of the panel.

Said bottom and said bottom plate have an opening for the passage of said anchors during their installation.

The assembly of the panels is carried out by means of removable joining elements cooperating with a reserved groove on the lateral sides of the panels.

According to the invention, said upper and bottom plates protrude by the same value relative to said structure and around its periphery to form a peripheral groove of a rectangular cross section and have rectangular notches for passing the connecting elements when assembling the panels.

Said panels further include parallelepipedic connecting elements of a cross section corresponding to that of said groove so that they can be arranged and fixed in the latter near at least one of the sides of said notches, which connecting elements have on their face outward facing of the panel of the means for receiving said junction elements.

The latter take the form of keys of a cruciform cross section and said connecting elements comprise a groove with partially closed entry, in which groove is engaged a tongue of said cruciform keys.

The panels are rectangular or square and the notches on the longitudinal sides of the rectangular panels or on two opposite sides of the square panels are offset from their center and / or one of their angles.

In one embodiment, said notches are offset by the half-length of a connecting element.

In another embodiment, the upper plate has rectangular notches for passing said junction elements during the assembly of the panels, which also include connecting elements of a cross section in the shape of a C with unequal wings and comprising, opposite the latter, two right angles for fixing said connecting elements in said groove of rectangular section, which elements further comprise a groove of a circular cross section with partially closed profile, parallel to said wings and are fixed in line with said notches, the shortest wing being located substantially at the edge of the notch, the longest wing being substantially at the edge of the bottom plate.

Said junction elements are made of elastically deformable plastic and comprise tongues of a circular cross section to cooperate with the grooves of said connecting elements, the assembly of the panels being effected by forced engagement of the tongues of the junction elements in the grooves connecting elements.

Said junction elements are of a cross section adopting the general shape of a T and comprise two tongues parallel to each other extending symmetrically on either side of a very thick rib, which corresponds substantially to twice the width of a notch so that the rib fills the space left by the notches of two assembled panels, the upper part of the rib lying substantially in the plane of the upper plates of the panels.

With regard to rectangular panels, the notches are reserved in the middle of the sides of the panels and at their angles, those reserved for said angles being of a length reduced to half the length of the other notches.

The corner notches extend in the direction of the longitudinal sides of the panels and in said corner notches are fixed connecting elements reduced to half of said connecting elements fixed to the right of said reserved notches in the middle of the sides of the panels.

The upper plates and the bottom of the panels consist of at least one weaving of synthetic fiber or glass fiber yarns, the voids of which are filled and the yarns coated with a mixture of synthetic resin and low density granular materials. The honeycomb structure is glued to said plates and the upper plate has roughness to reduce the risk of skidding of vehicles traveling on the track.

In a preferred embodiment, said weaving is three-dimensional and the synthetic resin is mixed with glass microbeads filled with air.

In one embodiment, this mixture consists of 1 to 3 volumes, preferably 2.5 volumes, of granular material or glass microbeads for one volume of synthetic resin.

In the case of loose soil, the track consists of a rot-proof textile fixed to the ground by anchoring means;
- a layer of leveled sand or fill, located above said textile and a plurality of panels arranged on said layer and connected together and fixed to the ground by means of anchors.

According to the invention, the method of implementing an emergency rolling track on loose ground is characterized by the following operations:
- a rot-proof textile is placed on the ground;
- This textile is fixed to the ground and it is prestressed by anchoring means distributed over the surface of said textile;
- the textile is covered with a layer of sand or fill;
- compact and level the sand or fill;
- laying panels on the sand where the compacted and leveled backfill is used;
- said panels are assembled together,
- They are fixed to the ground by means of anchors passed through said layer and said textile;
- And it acts on said clamping means and correspondingly on said elastic means to prestress the ground below said textile.

According to this process, the anchoring of the textile to the ground is carried out by prestressing the ground by creating beds made up of the ground itself.

• FIG. 10 is a partial top view of a track comprising panels assembled by means of the junction elements of FIG. 9.

Reference is first made to FIG. 1 of the drawing which represents a base panel 1 and to FIG. 2 which represents an additional panel 2 necessary for carrying out the start and end of the track.

The complementary panels are half the length of the base panels. The structure of these two types of panels is the same.

They comprise an upper rolling plate 1a / 2a, a bottom plate 1b / 2b and a cell structure 1c / 2c which connect said upper and bottom plates. The structure 1c / 2c is for example of honeycomb whose walls extend from one plate to another, for example this structure is made of molded plastic material such as polyvinyl chloride or aluminum.

Said plates 1a / 2a - 1b / 2b overflow by the same value with respect to the structure 1c / 2c and on the periphery thereof to form a peripheral groove 1d / 2d with a rectangular cross section. This comprises rectangular notches 1e / 2e reserved in the parts of the plates extending from said honeycomb structure 1c.

The base panel 1 which is rectangular has a notch in the middle of its short sides and two notches on its longest sides.

As illustrated in FIG. 1, these notches are offset from the middle of said longest sides and symmetrically from one side to the other, so that a notch 1e₁ is brought closer to the short sides of the panel while the other 1e₂ is far from it.

The complementary panel 2 is square and has a notch 2e in the middle of two of its opposite sides and a notch 2e₁ offset from the middle of its two other sides.

Said notches are offset from the middle of the square or rectangular panels or from one of the angles of a rectangular panel by the half-length of a connecting element which will be described later.

The panels 1/2 further comprise housings 1f / 2f, for example cylindrical or cylindro-conical, which extend from the upper plate 1a / 2a to the bottom plate 1b / 2b.

Said housings adopt the general shape of a slightly conical cup (Figure 5) from top to bottom, the bottom 1f₁ is applied to the bottom plate 1b / 2b of the panels. The bottom 1f₁ and the bottom plate 1b / 2b have an opening 1f₂ / 1b₁ to allow the installation of an anchor 3, the mounting of which will be given in detail below.

At their upper part, the 1f / 2f dwellings have a peripheral edge 1f₃ which is inserted into the thickness of the upper plate 1a, the fixing is carried out by gluing or by any other perfectly known suitable means. Said housings are closed after placing the anchor 3 by plugs 4 with a circular outline fitted into their upper opening and being placed substantially in the plane of the external face of the upper plate 1a / 2a

The upper plates 1a / 2a and bottom 1b / 2b consist of at least one weaving of threads of synthetic fibers such as polyester or glass fibers.

The voids of this weaving are filled with a mixture of a synthetic resin, for example an epoxy resin, with granular materials of very low density, for example glass micro-beads filled with air. The weaving threads are coated with this mixture of resin / glass microbeads.

In one embodiment, the weaving is three-dimensional and said mixture coats the weaving threads and occupies the volumes formed by said threads.

In another embodiment, the upper plate 1a is formed from two superimposed weaving layers 1a₁ / 1a₂ as shown in FIG. 5. In this figure the flange 1f₃ of the housing 1f is inserted between said weaving layers 1a₁ / 1a₂ .

The upper plate 1a / 2a of said panels has roughness on its outer face to reduce the risk of skidding of vehicles traveling on the track. These asperities can take any known form such as a granite surface, ridges, ribs or the like. The mixture of synthetic resin / glass microbeads and, in a preferred embodiment of the panels, consists of a three volumes of glass micro-beads for one volume of synthetic resin.

The optimal result is obtained with a mixture comprising two and a half volumes of glass micro-beads for one volume of synthetic resin, for example epoxy resin.

The assembly of the panels together is obtained by parallelepipedic connecting elements 5 of a rectangular or square cross section and adapted to be able to be arranged in the peripheral groove 1d / 2d. These elements 5 are therefore of a cross section slightly smaller than the throat section 1d / 2d. As shown in Figure 4, the panels that make up the track are offset by half a length from one row to another, the connecting elements 5 are fixed for example by gluing on one side of the notches . The elements 5 fixed to the longitudinal sides of said panels are placed at their right angles as shown in dotted lines in FIG. 4.

Said connecting elements comprise for example a groove 5a of a circular cross section with partially closed entry, reserved on one of their faces 5b, that placed outside the panel. The panels are joined together by keys 6 of a cross-shaped cross section and whose tongues 6a which are of a circular cross section and are thus adaptable to said grooves 5a of the elements 5. For example these keys are produced in a rigid material and for their implementation, they passed through said notches 1e / 2e and are engaged in the grooves 5a of the connecting elements 5 by a thrust exerted along the longitudinal axis thereof.

Figure 9 is a sectional view of an assembly of two panels 1 in another embodiment according to the invention.

FIG. 10 represents the arrangement of said panels 1.

As in the case described with reference to FIG. 4, the panels which make up the track are offset by half a length from one row to another.

The connecting elements 5₁ are fixed for example by gluing in the peripheral groove 1d of the panels, in line with indentations 1g / 1h made on the lateral sides of the upper plates 1a of said panels. As shown in FIG. 10, said notches 1g are made in the middle of the longitudinal and transverse sides of the panels which also have other indentations 1h reserved for their four angles. Said notches 1h are reduced to half the length of the notches 1g.

They receive connecting elements 5₂ which are themselves reduced to half of the elements 5. According to this embodiment, the notches 1g are reserved in the upper plates 1a only and are provided for passing therein junction means 6₁ for cooperate with said connecting elements 5₁ / 5₂.

Said elements 5₁ / 5 éléments are of a C-shaped cross section with unequal wings.

The wing 5₁b extends substantially to the edge 1b₁ of the bottom plate of the panels, the wing 5₁a of shorter length extends substantially to the edge 1g₁ of the notch 1g. It is the same for the 5₂ connecting elements fixed to the right of the 1h angle notches.

Said elements 5₁ / 5₂ have a groove 5₁c of a circular cross section with partially closed profile which joins said wings 5₁a / 5₁b and which is parallel to these and further comprise, opposite said wings, two right angles 5₁d joined by a face 5₁e of the connecting element, so that said elements 5₁ can be embedded just in the peripheral groove 1d for their attachment which for example is achieved by gluing.

Said junction elements 6₁ are of a cross section adopting the general shape of an inverted T in their assembly position as illustrated in FIG. 9.

They have two tongues parallel to each other 6₁a / 6₁b symmetrical with respect to the axis xx₁ and has a very thick rib 6₁c which corresponds substantially to twice the width of a notch 1g / 1h, so as to fill the space left by said notches of two panels in the assembly position.

The upper part of the rib 6₁c is located substantially in the plane of the upper plates la of the panels.

The tongues 6₁a / 6₁b are of a circular cross section to cooperate with the grooves 5₁c of the connecting elements 5₁ as shown in FIG. 9.

Said junction elements 6₁ are made of elastically deformable plastic and the panels are assembled by forced engagement of the tongues 6₁a / 6₁b of junction elements 6₁ in the groove 5₁c of said connecting elements 5 éléments / 5₂

The weighting of the panels 1/2 is carried out in an embodiment by anchoring in the ground. The anchors 3 used are of the type that is the subject of the FR.A. patent. 2,622,909 of the plaintiff.

As the ground is mainly powdery, the panels are directly anchored in the ground. Such an anchor 3 comprises an articulated rod 3a, the free end of which is threaded to receive a tightening nut 7 and a locking lock nut 8.

The rod 3a is passed through the openings 1f₂ of the housings 1f and 1b₁ of the bottom plate Ib of the panels and also into the orifice 9a of a support plate 9, for example of a circular outline and arranged in the bottom of housing 1f.

The prestressing of the ground is obtained by screwing the nut 7 on the rod 3a and by means of spring means for example BELLEVILLE washers 10 disposed between said support plate 9 and a washer 11 on which the nut clamping 7 is in support.

This anchoring is carried out after surfacing the ground with light means such as for example a heavy beam towed by a light 4x4 vehicle. the panels 1/2 are therefore fixed in the ground by means of said anchors 3.

The anchors thus produced allow, taking up a force in the ground, to sufficiently weigh the panels until an acceptable bearing capacity of the ground is obtained. For example, a concrete slab with a square meter of surface and a thickness of fifty centimeters prints on the ground a pressure of 0.0125 MPa.

The proposed anchors print a substantially equivalent pressure of 0.01 MPa, which corresponds to weighting in recovery of effort of the order of one tonne.

In addition, said anchors give the panels, despite their lightness, great resistance to sliding.

In the case of loose soil, prestressed seats such as those defined in the FR patent are produced. A. 2,622,909 above a rot-proof fabric called geotextile, then these prestressed foundations and said fabric are covered with a thin layer of soil.

This layer is vibrated or compacted by a light means before being covered by said panels 1/2.

There is thus placed on the ground 12 (FIGS. 6 to 8) a rot-proof textile, for example a bitumen complex 13 which is fixed to the ground by anchoring means distributed over the surface of said textile and each comprising an anchor 3 of which the rod 3a is passed through the textile 13, a seat 14 disposed above the textile 13 and subjected to blocking means. for example by corner effect 15 and spring 10 obtained by BELLEVILLE washers, for example, for prestressing the ground.

The textile 13 and the foundations 14 are then covered with a layer of fill or sand which is compacted and then leveled by the aforementioned light means and placed on the sand where the compacted and leveled fill 16, the panels of coating 1/2. These panels are assembled together as described above.

Panels 1/2 are then fixed to the ground 12 by means of anchors 3 passed through the layer of sand 16 and the textile 13.

The anchoring of the panels and the textile to the ground is thus carried out by prestressing the ground by creating solid masses made up of the ground itself.
