Abstract

A geotextile unit comprising a rigid mesh combined with geotextile material.

Claims

1. A porous geotextile unit comprising a porous geotextile material and means for minimizing the stretching of the porous geotextile material including a rigid mesh of construction steel rods and means for integrally coupling the porous geotextile material to the mesh wherein the porous geotextile material comprises first and second sheets of porous geotextile material disposed on opposite sides of said mesh and the means for integrally coupling the porous geotextile material to the mesh comprises heat welds joining said first and second sheets of porous geotexile material only at the areas between the rods.

2. The geotextile unit of claim 1 wherein the construction steel rods are arranged in rows and columns.

3. The geotextile unit of claim 2 and also comprising means for welding the rods together at intersections of the rows and columns.

4. The geotextile unit of claim 2 wherein the geotextile material is removed from selected areas of the unit and wherein the rods form protuberances.

10. The geotextile unit of claim 1 and also comprising a sheet disposed on one side of the mesh and formed of a material having less friction than the geotextile material.

5. Apparatus for soil reinforcement for use in repairing or preventing slips and landslides or the construction of steep slopes, said reinforcement apparatus comprising a plurality of porous geotextile units each comprising a porous geotextile material and means for minimizing the stretching of the porous geotextile material including a rigid mesh of construction steel rods and means for integrally coupling the porous geotextile material to the mesh wherein the porous geotextile material comprises first and second sheets of porous geotextile material disposed on opposite sides of said mesh and the means for integrally coupling the porous geotextile material to the mesh comprises heat welds joining said first and second sheets of porous geotextile material only at the areas between the rods,

said units used as components of the fill to separate layers of the fill thereby interrupting failure planes,

said units assuring friction with the fill, and

said rigid mesh comprising means for preventing the stretching of the material while enabling the forming of the geotextile units.

6. The soil reinforcement apparatus of claim 5 and also comprising wall means and means for attaching the geotextile units to the wall means.

7. The soil reinforcement arrangement of claim 5 and also comprising wall means comprised of stacked hollow blocks, and where protuberances of the mesh of the geotextile units are bent to extend into the hollow blocks.

8. The soil reinforcement arrangement of claim 7 wherein the hollow blocks are precast in one unit.

9. The soil reinforcement arrangement of claim 7 wherein the hollow blocks are staggered to provide stadium like seating arrangements.
