Abstract

The invention relates to hydraulic construction, in particular to protective and regulatory structures used to protect river banks from erosion and their restoration. The purpose of the invention is to increase the efficiency of work. The semi-pond consists of interconnected links 9 of block 1, the converging walls 2 and 3 of which form a protrusion 6 facing the bed. Through channels 4 pass between walls 2 and 3 of adjacent blocks 1. Each block 1 is provided with a bottom plate 5, which prevents the foundation of the base in the through channels. The slot 8, made in the projections 6 of the blocks, the smaller length and height of the walls 2 of the blocks 1 on the side of the upper pool allow to effectively influence the bottom layers of the flow, which attract sediments, and contribute to their deposition in the lower pool of the semi-ponds. 3 hp f-ly, 6 ill.

The invention relates to the construction of gypsum structures, in particular, to protective and regulatory structures used to protect the coast from erosion and their restoration.

The purpose of the invention is to increase work efficiency.

Fig, 1 schematically shows a semi-pond, top view; FIG. 2 is a section A-A in FIG. 1; in fig. 3 is a section bb of fig 1; Fig. 4 shows the execution of blocks with slits; in FIG. 5, the execution of the walls of the blocks from the upstream side of shorter length in FIG. 6 is the same from the upstream side of a smaller height.

The semi-pond includes interconnected blocks 1, installed in a row and made with converging walls 2 and 3, forming through the length of blocks 1 through channels 4 from the upstream to the lower. Blocks 1 in the row are installed at intervals that increase the penetrability of the semi-ponds. Each unit 1 is provided with a bottom plate 5 placed in its cavity. The converging walls 2 and 3 in the plan form a protrusion 6 facing the channel,. The protrusion 6 of each subsequent block 1 is located in the cavity of the previous block 1, slots 8 are made in the protrusions 6, the walls 2 of blocks 1 from the side of the upper pool are made smaller than the walls 3, located on the side of the lower pool. In addition, the walls 2 of the blocks 1 from the side of the upper reach are made of a smaller height than the walls 3 located on the side of the lower reach. Blocks 1 are connected by links 9,

The semi-pond works as follows,

Between, the walls of walls 2 and 3 of adjacent blocks 1 and bottom plates 5 are formed through channels 4, which intercept the bottom layers of the flow. The movement is in the form of circulation currents with the power and ability to transport solid flow particles. When the flow through the semi-pond is of a shallow depth, commensurate with the height of the blocks 1, the flow is slightly higher

currents out into the downstream. Due to the loss of speed in the bend of the channels 4, the outgoing currents are less than the permissible non-blurring speeds

Making a slot 8 in the protrusion 6 of the block 1 facilitates wind speeds and levels in adjacent circulation currents that pass through adjacent through channels 4, improves the process of passing the pumps and accumulating them along the shore beyond the semi-pond.

Making the walls 2 of the blocks 1 smaller in height and height as compared to the walls 3 allows the process of nano-regulation to be carried out at lower energy costs, provides safe passage of floods through the structure if there is large sediment in the flow
