(57) Abstract:

The invention allows for reduced labor costs and increase operational reliability. This is achieved by the fact that retaining wall, comprising placed one above the other bearing fastening elements made in the form of rasevych cells filled with an inert material and formed from interconnected by means of projections and depressions horizontal elements, characterized in that raziye cells are located at a distance from each other, and between them successively from bottom to top is placed a layer of inert material filling the cells and the layer of slag monolith body propped up the slope, the lower rajeeva cell made with bearing fasteners, and the lower surface of the horizontal elements are made in relief. 7 Il.

The invention relates to the construction and can be used mainly for attaching earthworks of the rock, half-rock and monolithic slag rocks.

A known method of construction of hydraulic earth structures, consisting of a nucleus, lateral prisms and transitional zones between them, including layer-by-layer stacking, levelling zones between the tion in the outer layers, which is dangerous from the point of view of a breach of its filtration properties, especially when the nuclei of small thickness.

Closest to the technical essence and the achieved results is the construction of retaining walls, which are collected from the same type rasevych beams, stacked horizontal rows. For mutual engagement and horizontal adjustment of the beams on their surfaces are made corresponding to each other combs and frames. Side, top and bottom walls of these vzaimosoedinenii beams form a series of rectangular cells filled with corresponding material. Using incremental beams erected vertical retaining wall of a given height [2]

A disadvantage of the known construction of the wall is significant complexity and low reliability when mounting slopes, consisting of slag monolith body, propping up the slope.

The purpose of the invention reduce labor costs and increase operational reliability.

This objective is achieved in that the retaining wall, including measured over each other carrying fastening elements made in the form of rasevych cells filled with an inert material and formed and the new cells are located at a distance from each other, and between them successively from bottom to top is placed a layer of inert material filling the cells and the layer of slag monolith body propped up the slope, the lower rajeeva cell made with bearing fasteners, and the lower surface of the horizontal elements are made of relief.

Analysis of the known technical solutions in the area of study allows to draw a conclusion about the absence of these characteristics of the proposed retaining wall, and on the criterion of "substantial differences".

The significant distinguishing features from the prototype ensures that the proposed retaining wall to the criterion "novelty" and achieving a positive effect.

In Fig. 1 shows a General view of a longitudinal section of the retaining wall for mounting heat-treated slopes, Fig. 2 cross section of this retaining wall along a-a of Fig. 3 rarely element retaining walls, Fig. 4 and 5, the location of the hemispheres on the lower surface; Fig. 6 razavy element of the retaining wall of Fig.7 location of sinusoidal relief on its bottom surface.

Retaining wall for mounting heat-treated slopes consists of a nucleus slag mono, the Padin and ledges 5, layers of inert material 6 and carrying fastening elements 7.

Retaining wall for mounting heat-treated slopes is constructed as follows. Cut off at the bottom part of the core and slag monolith 1 level, putting an extra layer of inert material 6, for receiving the mounting wall surface 9 that is located parallel to the earth shoes 10, using the construction method of forming the indicated surface of the butt 11.

This filled the bottom surface 9 place raziye elements 2, which interact with the depressions and protrusions 5, form a closed circuit retaining wall 12. The contour of the wall of the fixed bearing fastening elements 7. The generated contour of the retaining wall 12 is covered with a layer of inert material 6.

The second and subsequent paths of the retaining wall 12 does not have a release bearing fastening elements 7, and the technology of their construction similar to the above.

The stability of the erected second and subsequent contours of the retaining wall 12 without carrying fastening elements 7 are provided by the lower surfaces rasevych elements made in the form of hemispheres 3 and sinusoidal the form of hemispheres 3, the porosity of the location on which the supporting surface elements in the General form described by the equation

< / BR>
where a is the angle between the straight lines passing through the centers of touching hemispheres.

In Fig. 3 shows rarely element 2 with the bottom surface, made of hemispheres 3 (see Fig. 4 and 5 layout hemispheres if the angle a is 60oand the 90o.

Maximum bearing surface is achieved by the location of the hemispheres in a checkerboard pattern, in which the angle a 60o(see Fig. 4), and the porosity is 0,259, respectively, the minimum bearing surface at an angle a of 90o(see Fig. 5) and the porosity 0,476.

The proposed surface rasevych elements allow to increase the bearing surface area of 1.4 1.7 times, respectively, will increase the stability of the formed retaining wall.

Maximum bearing surface rasevych elements made in the form of sine waves (Fig. 7), will increase the bearing surface is 1.6 times and eliminate the shift.

The proposed retaining wall through the use of mechanization of the construction will allow to reduce labor costs, and construction rasevych elements creates reliability of their attachment, and therefore poveromo A. A. Dam from local materials. M Stroiizdat, 1973.
