The invention relates to hydraulic construction and can be used for the construction of shore protection when laying trunk pipelines at crossings over rivers, reservoirs, slopes, slopes, etc.

The purpose of the invention is to reduce the cost of the shore protection facilities and increase the reliability of its work.

Figure 1 shows the shore protection structure and pipeline, frontal section; figure 2-raerez aa in figure 1; fig.Z - layout of synthetic mesh; in figure 4 · U-shaped anchor for fastening the mesh to the slope.

The shore protection structure is located above pipeline 1 on the surface of the planned coastal slope 2. It includes sowed on the slope 2. Grass 3, on top of which the synthetic grid 4 is laid with an overlap, 20-40 km overlap of the panels, the direction of laying perpendicular to the water edge against the flow. Along the upper and lower boundaries of the structure, there are pit areas 5, in which the edges of grid 4 are loaded with reinforced concrete blocks 6. The mesh of grid 4 between blocks 6 is filled with a layer of local mineral soil 7 with a thickness of 200-300 mm and fixed on the slope with U-shaped anchors 8. Backfilling pipeline 1 in a trench

Claims (3)

Claim 1. Shore protection structure, including placed above the underground pipeline on the strengthened coastal slope of a cloth of synthetic material and mineral soil, while the slope is fixed by sowing grasses, and the cloth is fixed to Otko15 su, characterized in that, in order to reduce the cost of the shore-protective structure and increase its reliability work, cloth synthetic material performed The e2θs are in the form of a grid and are placed with an overlap perpendicular to the water edge, while the end sections of the panels are fixed by means of reinforced concrete blocks, partially recessed in 25 holes made on the slope, and the mineral soil is laid flush over the panels between the blocks and fits flush with the part of reinforced concrete protruding above the slope above the slope, and reinforced concrete blocks are laid above the panels and are flush with the reinforced concrete part above the slope, and reinforced concrete blocks are laid over the slope of the reinforced concrete blocks above the panels that lie flush with the reinforced concrete part above the slope, and reinforced concrete blocks are laid over the slope of the reinforced concrete. 30 2. The construction according to claim 1, characterized in that the panels of the grid are made of multilayer, and between them lay a layer of soil. 3. The construction according to claim 1, characterized in that the surface layer of the soil is treated with a binder. 1486554
