Description

The invention relates to construction and relates to the constructive implementation of retaining walls and the method of their construction.

• Known retaining wall made of box-shaped blocks filled with soil and forming the vertical front ₅ and the rear face of the retaining wall.

When erecting it, the soil is developed, the bed is made of stone material and blocks are installed on it, after which the soil is backfilled with its layer-by-layer compaction [1]. Yu

The disadvantage of the known retaining wall is the need to backfill bed rock, as a retaining wall experiences significant resistance to ground, and the need to perform the backfill, which causes a large bone ¹⁵ laborious works for the construction of a retaining wall.

A retaining wall is also known, including trapezoidal blocks mounted on top of each other, forming a vertical front and inclined at an angle greater than the angle of repose of the soil, the rear face of the retaining wall.

The method of its construction includes soil development, installation of blocks and backfilling of the soil [2].

This retaining wall and the method of its construction are the closest solutions to the described invention.

The disadvantage of this retaining wall and the method of its construction is the great complexity of the work due to the need to perform backfilling of the soil.

The purpose of the invention is to facilitate the construction of a retaining wall.

This is achieved by the fact that the proposed retaining wall, including mounted on each other trapezoidal blocks, forming a vertical front and inclined at an angle greater than the angle of repose of the soil, the rear face of the retaining wall, is equipped with a wedge block with vertical and inclined faces placed under the lower trapezoidal block and buried in the soil of the base, and the proposed method of its construction including the development of soil and the installation of blocks, before developing the soil on the base set direction The element 727766 'is inclined with a wedge block inclined at an angle greater than the angle of natural slope of the soil, and a wedge block adjacent to it, and the soil is developed in front of the wedge block to the width of the retaining wall. 5

In FIG. 1 shows the described retaining wall, a transverse section; in FIG. 2-5 - the sequence of operations during the construction of the described retaining wall.

The retaining wall consists of a wedge block 1, trapezoidal blocks 2 with a front wall, trapezoidal buttress blocks 3. Blocks 2 with a front wall are mounted on the wedge block so that the height of the wedge block and blocks with the front wall is not less than the total immersion depth of the structure into the ground. The cavity of blocks 1 and 2, if necessary, can be filled with soil to increase the mass of the structure, determined by my calculation. Thus, the necessary height created by these blocks, or, which is the same thing, their number depends on the depth of immersion of the wall in the ground and the mass required for calculating the structure.

On trapezoidal blocks 2 with a front wall, buttress blocks 3 are mounted, which differ structurally from the first by the absence of a front wall and are not filled with soil. The number of buttress blocks is determined by the height of the retaining wall, ki.

, When erecting the retaining wall on a pre-aligned platform, expose the guide element 4, for example, an inverted trapezoidal block 3. Then, using the inclined rear wall of it as ³⁵ as a guide, expose the wedge block I. Under the influence of gravity, this block is immersed by a certain amount in the ground . Then, soil is developed in front of the wedge block 1 and the block 1 is immersed under the action of its own weight jq, sliding the rear inclined face along the guide element 4.

After the wedge block 1 is deepened, the trapezoidal blocks 2 and 3 are mounted and monolithic. Under the action of gravity ⁴⁵ , the wall slides into the ground along an inclined plane, which increases during the development of the soil in front of the blocks.

When the retaining wall is immersed, its front edge moves forward by the width of the wall.

The stability of the structure is ensured by the distribution of its gravity and the pressure of the soil in front of the buried part of the structure. The implementation of the retaining wall with a wedge block can significantly reduce the complexity of its construction, provides the ability to perform work in several stages, and the construction of the retaining wall as a berthing structure eliminates the need for expensive underwater technical work and provides the ability to perform dry work both from the shore, and from the water area.

(54) Retaining wall and method of its construction with an inclined angle exceeding the angle of repose of the soil, the face and the adjacent wedge block adjacent to it, and the development of the soil is carried out in front of the wedge block to the width of the retaining wall. FIG. 1 shows the described retaining wall, transverse section; in fig. 2-5 - the sequence of operations during the construction of the described retaining wall. The retaining wall consists of a wedge block 1, trapezoidal blocks 2 with a front wall, and trapezoidal counterforce blocks 3. Blocks .2 with a front wall are mounted on the wedge block in such a way that the height of the wedge block and blocks with a front wall is not less than the full depth of the structure in the ground. The cavity of blocks 1 and 2, if necessary, can be filled with soil to increase the mass of the structure, which is determined by calculation. Thus, the required height is created by these blocks, or, what is the same, their number depends on the depth of the wall in the ground and the required mass of the structure. On the trapezoidal blocks 2 with the front wall, counterforce blocks 3 are mounted, which differ structurally from the first ones by the absence of the front wall and are not filled with soil. The number of counterforce blocks is determined by the height of the retaining walls. When the retaining wall is erected, a guide element 4, for example, an inverted trapezoidal block 3 is exposed on a previously leveled area. Then, using its inclined back wall as a guide, the wedge block 1 is exposed. the block is immersed by some amount in the ground.
