The invention relates to hydraulic engineering and can be used to protect the banks of reservoirs, rivers, lakes and seas, slopes of dams from the damaging effects of waves and currents, in particular for the construction of jetty breakwaters and breakwaters, as well as draft elements when blocking river channels and seletok.

Fencing structures from the outline of arrays are known.

The drawbacks of bulkhead structures from ordinary massifs are: high demand for concrete, high likelihood of cracking, cracking, and spalling of faces when exposed to waves, flows, and when the draft is disturbed due to bottom deformation and collision with each other during the draft process.

The closest to the invention in technical essence is a unit for hydraulic structures, made in the form of a rectangular or figured element with high wave-breaking capacity.

The disadvantages of the known structures include an increased likelihood of cracking and spalling of the faces when exposed to waves, flows and when the outline is disturbed due to bottom deformation and collision with each other during the outline and during operation of the structure; reduction of overhaul periods, operation due to a natural violation of the structure profile due to a decrease in the volume of arrays over time.

The purpose of the invention is to increase work efficiency.

The goal is achieved in that the block is made in the form of an array with attached to it, made of interconnected tires, flexible, freely mounted garlands, capable of being located above the surface of the array when immersed in water.

The essence of the invention lies in the fact that the proposed block has attached to it, made of interconnected tire covers of garland, facilitating a soft landing when sketching blocks of subsequent upstream channels, as well as mutual anchoring of the blocks when moving them.

In FIG. 1 shows one of the options for the gravitational part of the block; in Fig.2 - another variant of the gravitational part of the block, not with

horizontal, and with a vertical arrangement of through holes; in FIG. 3 - the proposed unit in the process of lowering (parachuting); in FIG. 4 - a pipe cross placed in the block in FIG. 1; in FIG.

5 - a protective structure using the proposed blocks.

The block is collected as follows. The gravitational part of block 1 has holes 2 and 3 on the lateral faces, and block 4 has holes

the upper and lower faces of the holes 5, through which flexible connections 6 are passed, forming with a string of ring elastic elements 7 of them garlands. During the concreting process, a crosspiece of old-fashioned pipes is laid in the gravity part of block 1, consisting of transverse 8 and longitudinal 9 cuts, so that the holes .2 and 3 coincide with the edges of the shuttering drawing. Block 4 is assembled similarly, but vertical pipes are laid in it, forming holes 5 on the faces of the holes.

Sketching of blocks 1 and (or) 4, for example, in a protective structure, provides

parachuting them in the underwater zone, thereby creating soft landing conditions for each block. In the surface zone, the gravitational part of the block of subsequent channels is also laid on the main part

block of previous Russ outline (or styling) ..

The efficiency of the block is determined by the saving of concrete during the construction period and during operation, as well as

increased efficiency of the draft energy of the outline, leading to an increase in the efficiency of the unit and the structure as a whole.

The claims The block for the construction of a hydraulic structure, made in the form of an array, characterized in that, in order to improve work efficiency, the block

it is provided with flexible ties fixed to its lateral faces in the form of daisy chain and with tires mounted on them, located when the unit is immersed in water above its upper surface.
