The invention relates to hydraulic construction and can be used for construction of dams, dams, lintels in a pond.

The aim of the invention is to increase operational reliability and durability.

Figure 1 shows the proposed hydraulic containment coopy; figure 2 - section aa in figure 1 in fig.Z - section bb in figure 2.

Hydrotechnical protective structure, for example, a jumper erected in a pond, consists of vertical 1 cells closed on the sides and connected to each other, curvilinear in plan and made flexible from synthetic materials. Cells 1 are formed by outer 2 and inner 3 shells, which are interconnected by bridges, which in the upper part form closed cavities 4 filled with compressed air. Cavities 4 can be made around the entire perimeter of the cells and used as float, elements. The internal cavity of cells 1 is filled with soil 5.s

If necessary, cells 1 can be loaded from the sides of the upper and lower pools with earth prisms 6. Float elements, in which closed cavities 4 can be used, can be attached to the bottom of the reservoir during erection and operation with the help of bark 7. In the lower part, loading elements 1 8 can be attached to the shells of the cells 1, and from the upper side of the shell, shells can be made with screen 9.

When the jumper is placed, closed cavities 4, -formed in the upper part of the outer 2 and inner 3 shells, sectionally filled with compressed air, perform the function of float elements and provide the walls of the cells 1 with a predetermined position in the pond.

The internal cavity of the cells 1 is filled with soil 5, due to which a bridge is built to acquire the shape

due to the effect of; lean to the shells 2., and the 3 lateral pressure of the soil 5 of the backfill, which causes tensile forces in them, turns out to be ready for work. Water is pumped out of the space enclosed by a bridge

When operating from the upstream side to the proposed hydrostatic pressure protective structure, the said structure works as gravity, whose resistance to shear and tilting is provided by filling cells 1 with soil 5 when soil 5 and shells 2 and 3 work together. Lateral pressure of soil 5 acting the sides of the internal cavity, perceived by the shells 2 and 3, forming the cells 1, causes tensile forces in them, ensuring the given shape of the joint; Keny, as well as joint work eyki 1 and 5 backfill soil.

Claims (2)

1. Hydrotechnical protective structure erected in a pond, including interconnected vertical curvilinear cells in plan with flexible walls from outer and inner shells, with loading elements, and soil in internal cavities, characterized by the fact that increase of reliability in work and durability, it is provided with bridges connecting the inner shells of the cell walls and forming in the upper part of the cells all around their perimeter solid closed cavities filled with compressed air and crusts connected by stretching from the pressure side to the bridges, while the entire height of the structure. " 2. The structure according to claim 1, wherein the cells are made in a vertical plane along the stream of trapezoidal section, increasing towards the base. fF
