Abstract

The invention allows to increase the carrying capacity of the retaining wall. The retaining wall includes a front fencing 1, anchor elements, each of which is made in the form of a flexible tape 3, bent around a loop 4, which is located outside the bottom-up prism of the soil backfilling, and the foundation plate 2. Loop 4 of anchor elements bends around the soil massif and is made cylindrical surface, screw surface or has a double curvature of the saddle shape. 3 hp f-ly, 3 ill. (L tjtjus.2

Description

The invention relates to the construction. In the case of the construction of a wall of monolithium and can be used lithore reinforced concrete, it can be

during the construction or strengthening of retaining walls.

The purpose of the invention is the higher bearing capacity of the retaining wall.

1 shows a retaining wall with anchoring elements curved around a loop having a circular outline; figure 2 - the same, with anchor elements, curved around the loop, having a helical outline; figure 3 - the same, with anchor elements, curved on having

about ,

double curvature of saddle shape. The retaining wall consists of the front fence I mounted on the base plate 2.JlHu; eBoe the fence has through holes for anchor elements, made into a flexible tape 3, forming a loop 4, which may have a cylindrical surface (FIG.), A helical surface ( Fig. 2) or the double curvature of the saddle shape (Fig. 3) .. Radius. the curvature of the tape 3 in the area of the loop 4 is taken as 0.5-1.5 m, and the width of the strip is 0.25-0.50 m due to the prevention of the occurrence of significant plastic deformation zones at the ends of the loop. The vertical and horizontal distances between the ends of the belts 3 in the anchor element are equal to 0.8-1.3 of the loop curvature radius due to the condition of equal strength on the ground mass drilled by the strip.

The installation of the retaining wall is carried out as follows.

After installing the foundation slab and front fencing with openings for the passage of anchor elements, the sinuses are backfilled with a wall pane with layer-by-layer tamping and curvilinear wells are drilled in the soil mass, then the anchor elements are filled into the cavity, and then the cavity of the well is filled . .

solution. The anchoring elements are fixed --50 so that the loop of flexible lazy on the front fence of the retaining wall is bolted.

It was erected to the full height, and the work on filling the sinuses and anchoring device was performed in a consistent manner.

The horizontal pressure from the soil mass, which is transferred to the retaining wall, causes tensile stress in the ribbons 3. At the same time, radial pressures and tangential stresses arise in the ground covered by the loop of the soil mass to be covered.

At the same time, reactive stresses appear in the soil mass adjacent to the shear sections of the massif, and large volumes of soil are involved in the work, resulting in the dispersion of stresses in the massif surrounding the anchor elements, which significantly increases the bearing capacity of the retaining wall.

Claims (4)

1. Submerged wall, including a front fence and anchor elements, each of which is made in the form of a flexible tape, placed in the backfill soil and attached at one end to the front fence, characterized in that, in order to increase the bearing capacity of the retaining wall, each one is flexible the tape is curved around the loop and attached to the other end of the front fencing, with a loop formed by flexible; (the tape is seen outside the rir prism of the backflushing soil. 2. The shade of pop. 3. The wall according to claim 1, wherein the loop of the flexible tape has a helical surface. 4. A shade of pop. 1, distinguished, has a double curvature of the saddle shape. eftcis.f (fJuff.3
