Definitions

  • the present invention relates to a light work of land consolidation.
  • JP-A-60-3321 the construction of a retaining ouozage is proposed, comprising the insertion of concrete wall elements into a U-shaped groove made in a concrete foundation.
  • the invention therefore relates to a light soil consolidation structure, comprising a substantially U-shaped concrete footing, into which is inserted at least one parallelepipedal element characterized in that the element is made of a cellular plastic material in the form of 'a block, the upper part of said element projecting from the sole being successively covered by a mesh and a thin layer of concrete.
  • the cellular plastic material in the form of a block may in particular be expanded polystyrene or honeycomb polypropylene, or any other similar material.
  • the block of cellular plastic material can be provided, at its lower part projecting from the concrete base, with barbacans.
  • the part of the block of cellular plastic material inserted between the two branches of the U-shaped sole can be grooved on its lateral faces to offer better adhesion to concrete.
  • the block of cellular plastic material has a slight angle between the vertical and the slope (i.e. the edge of the ground to be consolidated) to take into account the bending of the material at the time of loading.
  • connection can be made using at least one steel rod, in particular twisted, laterally crossing the blocks and optionally folded at the end.
  • the blocks can be linked together by gluing.
  • the light land consolidation structure according to the invention can be installed, for example, in the following manner.
  • the blocks of cellular plastic material are cut to the desired dimensions and, if necessary, their lower lateral part is grooved for example with a saw. Furthermore, the foot of the slope to be consolidated is released.
  • the base of the U-shaped concrete footing is poured in situ and the blocks of cellular plastic material are aligned on top and linked together by means of steel rods or glue. Then the two branches of the U-shaped concrete footing are poured.
  • the ground is backfilled and the upper part of the blocks of protruding cellular plastic material is successively covered with a mesh and a thin layer of concrete by spraying.
  • the lightweight land consolidation structure according to the invention is particularly easy to implement and offers great safety in use, for example during road construction.
  • the light land consolidation work or light wall shown in FIG. 1 comprises a concrete footing 1 substantially in the form of a U, in which is inserted a parallelepipedic element 2 made of a cellular plastic material in the form of a block, the upper part of said element protruding from the sole being successively covered by a grid 3 and of a thin layer of concrete 4, for example by spraying by means of a nozzle 5.
  • the dimensions of the concrete footing 1 can be for example: width 1.10 m, height 0.55 m, height of the branches of the U 0.30 m, the length being chosen according to consolidation needs.
  • the block 2 of cellular plastic material in particular of expanded polystyrene (for example “Compyryrene”) can have as dimensions for example: height 1.20 m, width 0.50 m, and the lateral faces of its inserted part, to a depth of 0.30 m for example, in the concrete footing 1, can be grooved (not shown) using a saw.
  • the useful height of this wall according to the above dimensions is approximately 0.90 m.
  • the lower part of the block 2 protruding from the sole 1 is provided with a system of barbican 6 having for example a diameter of 5 cm allowing the drainage of water.
  • the block 2 usefully has a slight angle of about 2 ° between the vertical and the slope to hold the bending of the cellular plastic material at the time of loading.
  • Figs. 2 and 3 represent a light structure for consolidating land of dimensions larger than that of FIG. 1, of which the concrete footing 1 has for example as dimensions: width 2.20 m, height 1 m, width between the branches of the U 1, height of the branches 0.75 m, the length can be varied at will.
  • Several blocks 2 of cellular plastic material, in particular of polystyrene, having for example as dimensions 2.50 mx0.50 mx 1.20 are inserted into the sole over a depth of 0.75 m.
  • the blocks 2 are linked together by means of twisted steel rods 7 having for example a diameter of 8 mm. If necessary they can be glued.
  • the mesh 3 the thin layer of concrete 4 sprayed by a nozzle 5 and the barbican 6, the embodiment may be identical to that of the structure of FIG. 1.
  • the useful height of the wall is 2 m.
