Abstract

The invention relates to regulating hydraulic structures, in particular to filtering dams, and can be used for anti-filtration protection of natural reservoirs. The purpose of the image 1) eteni - increase the efficiency and stability of the dam. In the filtering dam, the horizontal cables are arranged in rows in parallel vertical and horizontal planes, and the ring elements (QE) are strung on the cable in the form of a comb with a step equal to their thickness. The CEs of each of the adjacent rows are mutually inserted into the corresponding gaps between the CEs of the adjacent rows. Four internal cables of two adjacent layers are passed through the internal holes of the FE, each of which passes alternately through the internal holes of the FE of two adjacent rows or layers. CEs, mounted on the cables in the form of a comb, make it possible to more effectively block the channel, since the anchoring elements are located outside the flow area, which eliminates soil erosion. 4 il.

The invention relates to regulating hydraulic structures, namely filtering dams, and can be used for erosion protection of natural watercourses, as a mudflow dam to regulate flow on natural mudflows, and also as a water supporting structure on a deformable foundation.

The aim of the invention is to increase the efficiency and stability of the dam.

FIG. 1 shows a filter dam, a plan; in fig. 2 - the same, front view; in fig. 3 the same, transverse vertical section with a multi-bottom arrangement of elastic annular elements; in fig. 4 - the same, with the arrangement of the elastic ring-20 integral elements in a staggered order of cross-sectional area.

The filtering dam is made of annular elastic elements 1, mounted on the cables 2, which are fixed by anchors 3 in the slopes of the natural channel A, along which the stream 5 flows.

The filtering dam works as follows.

The flow of water 5 with sediments (including the smite-stone flow) passes along channel A and, up to the dam, is delayed, with part of the flow

to reduce the rate of movement of water in the stream. The elastic ring elements 1 are mounted on the cables 2 in the form of a comb and allow to block the channel more efficiently and reliably, since the anchoring elements are located outside the flow zone 5, which eliminates soil erosion in the area of their location.

The design of the dam is more stable due to the formation of a spatial lattice of ring elements. The material for the construction of the facility is recyclable tires that are quite durable in a water-air environment or specially made ring-shaped elements. The mobility of the spatial lattice of the structure also increases the reliability of its operation under the dynamic effects of flow.

Invention Formula The filtering dam is made in the form of a corrugated surface from elastic ring elements strung on horizontal cables, characterized in that, in order to increase the efficiency and stability of the dam, the horizontal cables are arranged in rows in parallel vertical and horizontal (water with fine sediments) has voids, and the elastic annular elements gradually seep through. through the dam, which makes it possible to regulate the flow - to hold the large sediments and reduce the flow intensity in the downstream.
