Description

The invention relates to hydraulic engineering construction.

The aim of the invention is to increase the effectiveness of slope protection by increasing the energy-absorbing ability of the coating.

Figure 1 shows the coating, a view in plan; figure 2 - coating, section aa in figure 1; in FIG. 3, a portion of the coating with a symmetry of water flows between the ring-shaped elements, a plan view; figure 4 is a ring-shaped element with the image of the threads in it, view in plan.

The covering of the slopes of a hydraulic structure consists (of Fig. 1) of ring-shaped elements 1, made in the form of recycled tires, and a filler 2 placed under the tires, in their cavities and between them. Tires 1 are placed in rows with a gap relative to each other. Culter windows 3 are made in the walls of each ring-shaped element 1. The inner filler of the ring-shaped element is made in the form of a macrosurved insert 4 with a height not less than the thickness of the ring-shaped element. The fixed position of the ring-shaped elements on the slope and between them is provided by connecting elements 5. The position 6 denotes the slope soil.

The coating is assembled and operates as follows.

On the soil 6 of the slope of a hydraulic structure, tire covers 1 is laid with a gap relative to each other. In the free space between the tires 1 and 8 of their cavities, the core 2 is laid in a layer to the level of the inner rim of the tire. A liner 4 is inserted into each tire. The liners 4 are attached to each other by connecting elements 5, the device is ready for operation.

The stream of water that rises from the slope rushes down from above. This stream is divided into two streams; external, flowing between ring-shaped elements, and internal, flowing inside each ring-shaped element. Water streams flow along the outer forming tires (Fig. E), i.e. on the protector. The flow is reduced as the distance between adjacent tires decreases. Increases the height of the stream, its speed. The flow reaches the side windows of 3 adjacent tires; Part of the flow flows through the side windows 3 in the cavity of the tires 1, The main part of the flow continues to flow further. Flow expansion begins. When the tires are wrapped around their outer parts, the flow encounters many resistances; roughness of protectors, tires, narrowing the flow, its expansion.

After expansion of the flow (Fig. 3) in the space between the four tires, the flow runs onto the adjacent tires,

located below. At the place of flow expansion, in the space between the four tires, turbulence occurs. On the roughness of the protectors, the narrowing, the expansion of the flow, the increase and decrease in the height and width of the flow is spent energy flow. This is how energy is extinguished in the external flow.

- Part of the total flow flowing from the slope through the upper window 3 of the tire enters (FIG. 4) into the internal cavity of the tire. The stream is divided into a portion flowing in circular formations in a cavity intended for an inflatable wheel chamber. The other part of the stream rushes

to the liner 4, flows in the space bounded by the forming liners. In this case, there are numerous turbulence due to the macro-roughness of the liner 4. In addition, there are resistances to the entrance and exit from the cavity of the coating through the windows 3. The curvilinearity of the paths, resistance to overcome the roughness, input and output losses - to overcome this, energy is consumed

flow.
