Abstract

The invention relates to the field of hydraulic engineering, in particular, to the construction of a shore-protective structure, and can be used to protect banks from erosion on rivers with high flow rates and easily eroded channels. The purpose of the invention is to simplify the design and reduce material consumption. The device has piles 1 with hollow, hooded blocks 2 mounted on them. In the intervals between the beds are stacked with vertical piles AET and AA AA piles of the same blocks 3 filled with ballast, and at the bottom of the bed are blocks 7 associated with blocks 2 and 3, on top of blocks 2 and 3, loading beams 5 were laid on the top of blocks 1, made along the edges with cutouts corresponding to the cross section of piles 1 corresponding to the shape. The vertical plane of the structure along the entire length of the darkened bank is gradual:; currents with higher speeds growth, completely eliminates the occurrence of transverse circulation of the flow with vortex phenomena. The bottom layer of the flow, falling into blocks 7, re-slows down and loses kinetic energy, as a result of which the bottom velocities fall, which leads to intensive sedimentation and the gradual filling of the internal openings of the blocks, guaranteeing the stability of the foundation structure from erosion. 5 il.

The invention relates to hydraulic construction, in particular to the construction of a shore protection structure, and can be used to protect banks from erosion on rivers with high flow rates and easily eroded channels.

The purpose of the invention is to simplify the design and reduce material consumption.

Figure 1 shows the proposed device, a view in plan; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 2; 4 shows a loading beam, a plan view; on fig.Z the same, side view.

The device for protecting the bank from erosion includes piles 1 with hollow toroidal blocks 2 mounted on them.

As block 2, used tires are used.

In the intervals between their 1 with blocks 2 mounted on them, they are installed in a straight line with the formation of vertical stacks of blocks 3 that are close to each other, similar to blocks 2. The space inside blocks 3 is filled with ballast 4. , laid with the help of notches 6 on piles 1. Rails, rolling, etc. can be used as beams, the length and weight of which is chosen from the condition of tight retention of blocks 2 installed without piles.

Blocks 7 are placed at the bottom of the channel - the same as blocks 2 and 3. Blocks 7 are connected by flexible connections with blocks 2 and blocks 3.

The device works as follows.

The flow of water, moving along the bank protection device, contacts with its surface from blocks 7 almost to the lower edge of beam 5 along the entire height h and length L of the structure.

ticking and horizontal direction due to the adjoining of blocks 3 to each other both along the vertical plane and along the horizontal plane, changes the entire kinetic structure of the flow. The vertical plane of the structure along the entire length of the eroded shore gradually absorbs longitudinal, longshore currents with elevated speeds and completely eliminates the occurrence of transverse circulation of the stream with eddy effects.

The bottom layer of the flow, falling into blocks 7, slows down and loses kinetic energy, resulting in lower bottom velocities, which leads to intensive sedimentation and gradual filling of the internal openings of blocks 7, ensuring the stability of the foundation from crushing.
