Abstract

The invention relates to the construction of a retaining wall and allows it to increase its carrying capacity while reducing material intensity. In order to build a retaining wall, two rows of grooves are extruded, which are placed in a checkerboard pattern. Each notch is filled to a part of the depth with concrete mix 6, after which a punch 7 is placed in the notch and the concrete mix is pressed upward to the mouth of the notch. As a result, a concrete lining is formed on the wall of the recess facing the front side of the retaining wall, which can be reinforced with rebar 5. Then, excavation is carried out until the excavation of the recesses is detected. 4 il.

The invention relates to the field of construction, in particular to a method for constructing a retaining wall.

The aim of the invention is to increase the carrying capacity of the retaining wall while reducing its material intensity,

Fig. 1 shows a plan for the excavations; Fig. 2 shows a cross section of the excavation during the formation of the concrete wall; fig.Z retaining wall, transverse section; the same is a variant of the stepwise reinforcement of the retaining wall.

The retaining wall is erected as follows

. Axis 1 is placed, on which transverse axes-2 are marked through distance L; the grooves of the first row, in this case, L 2aj where, and is the width of the tamper.

At points 2, a series of grooves 3 are formed by the impact method or by the indentation method, it is preferable to use a wedge-shaped, non-equilibrium rammer {sac most suitable for one-sided compaction of the soil. After it is removed from the soil, a recess 3s is obtained, around which it is formed; on the zone of compacted soil 4,, 30

After extrusion of the grooves on the inlet wall of each notch: 3, the rebar 5 is laid (conditionally shown), the recess 3 of the plaster plate 6 is recorded (for example,

; concrete) and with the help of a wedge-shaped punch 7 smaller than a notch. 3. The size is displaced by the material. 6 onto the inclined wall of the notch 3. with a partial virae popping it into the wall notch. When this happens in the lower part of the concrete wall in the compacted soil core reinforced concrete is formed; tooth Sj preventing shear and rotation of the wall.

Parallel to axis 1 and at a distance of 1 from it. the planned axis is 9, with 1 j b, where, b is the punch thickness.

On axis 9, the centers of the second row of grooves 3 are also marked at a distance L from each other in such a way that the grooves of the second row are arranged in a staggered order with respect to the grooves of the first row. Similarly, with the description of y, the grooves 3 of the second row are crushed and their inclined walls are concrete.

. After hardening of the concrete, extra ground is excavated until the exposed walls of the cavities 3 of the first and second rows are exposed. Then the gaps between the walls of the first and the second row are concreted.

As a result of the implementation of the method, an inclined, reinforced concrete wall of a broken contour is obtained, the protrusions of which perform the role of countermeasures and to increase the stability of the retaining wall.

If the projected height of the retaining wall is greater than the height of the tamper, then the retaining wall is erected in full, repeating all the above operations on each ruce.

As the height of the retaining wall increases, the volume of soil falling into the collapse prism increases, and the pressure of this soil against the retaining wall increases. In order to reduce this pressure, it is possible to perform an additional row of recesses 10 by placing them between the boundary of the prism of the collapse 11 and the retaining wall. The recesses 10 are made from a height of 0.5 to 0.8.

the heights of the main grooves 3. The notches 10 are filled with local soil and tamped.

When pulling out the grooves 10 around

It should be noted that for the formation of a zone of compacted

To wedge a tooth, you need a depth of the well. Make it somewhat lower than planned, the bottom of the excavation to complete the operation of facing oblique walls of boreholes

the soil 12, which, together with the compacted soil filling in the recesses 10, forms soil piles, parts but perceiving the pressure of the soil, the method is simple, it does not contain laborious and expensive operations.

In order to protect the walls of the grooves of the first-d5 iBoro range from destruction during the compaction of the second series of grooves in unstable soils, it is recommended to backfill them with compaction.

they form a zone of compacted

the soil 12, which, together with the rammed soil filling the notches 10, forms, soil piles, partially. but perceiving the pressure of the soil, the method is simple, its implementation does not contain time-consuming and expensive operations.
