Description

The utility model relates to the field of coastal protection structures that contribute to the prevention of erosion of the coastline.

Various wave-absorbing prefabricated hydraulic structures are known to be installed in a relatively shallow coastal zone to prevent possible destruction of the coastline.

A well-known outline protective hydraulic structure made of shaped concrete masses, which contains a stone bed, a body of randomly laid shaped concrete masses, a massive flexible diaphragm and a triangular prism (SU 1469007 A1.30.03.89).

The well-known overhead protective hydraulic structure has low operational characteristics, due to its massiveness it is subjected to a strong wave load, a wave is washed out.

A penetrating hydraulic structure is known, which contains a sketch of curly blocks or stone, poured into its holding frame with an open upper and lower end. The holding frame is completely immersed in water, its upper end is located below a calm water level, a prism from the same outline with loose slopes is placed on top of the frame. The upper mark of the prism is located above the water, the installation frame is located on the supports, its lower end is located above the bottom irregularities (RU 2200789 C2, 03.20.2003)

The disadvantage of this hydraulic structure is instability during the storm exposure to waves, as well as the destruction of the metal frame during the development of corrosion at the level of exposure to waves.

A prefabricated hydraulic structure is known, which is a flexible protective mat that contains concrete blocks interconnected in order and in rows with flexible cables, while in the upper part the blocks are made in the form of rectangular parallelepipeds by the minimum diameter of the cable bend ring, and the height of the truncated pyramids is less and equal to the height of the rectangular parallelepipeds (RU 2325474 C1, 05.27.2008)

However, the well-known prefabricated hydraulic structure has low operational characteristics due to the low stability of adhesion to the ground, and the presence of mechanical installation means is required.

A prefabricated slab is known, the contour of which is described by a rectangle, and on two opposite sides there are recesses in the form of isosceles trapezoidal, and the lower part of the plate is made in the form of a rectangle, the contour of which is reduced relative to the central axis parallel to the faces with recesses, by the depth of the trapezoidal recess of the upper part moreover, the transition between the corresponding offset lateral faces of the upper and lower parts is carried out using inclined planes (RU 2208080 C2, 07/10/2003).

Known element of prefabricated coating, which is a single unit in the form of a polyhedron, consisting of a lower part based on a horizontally oriented parallelepiped, one of the sides of which has a concave surface formed by faces located at an obtuse angle to each other, and the upper part containing the upper rectangular a face, beveled end faces in the form of faces based on a rectangular trapezoid, and sides, one of which is concave and formed by triangular faces (RU 177772 U1, 03/12/2018)

A disadvantage of the known elements of the prefabricated hydraulic structures are low performance due to the low stability of adhesion to the ground and the need to use flooring made of reinforcement and rubble.

The technical problem, which the proposed utility model is aimed at, is to expand the arsenal of technical means and create a module for a prefabricated hydraulic structure, the parameters of which provide improved operational characteristics.

The indicated technical result is achieved in the proposed module of a prefabricated hydraulic structure, which has the form of a block made in the form of a rectangular parallelepiped, on the upper and lower sides of which, relative to the central axis, left and right, recesses are made in the form of rectangles, and a hole is made in the center of each recess and on the opposite sides of the block are fasteners in the form of anchors.

The implementation of the module of a prefabricated hydraulic structure due to the declared form of the block with two recesses in the form of rectangles on the upper side of the block allows trapping sand, which through the holes enters the recesses of the lower side of the block, which creates the effect of a “trap” of sand and helps to keep sand in the coastline.

The use of fasteners in the form of anchors allows you to connect blocks with small gaps on the principle of "chain mail", with the formation of a large number of faces, which allows for wave-absorbing destructive forces of waves in intersecting directions and allows for the stability of the proposed prefabricated hydraulic structures, to increase operational characteristics and expand Arsenal of technical means of bank protection.

The essence of the utility model is illustrated by drawings, where in FIG. 1 is an isometric view of a precast unit with a 1/4 cut-out;

in FIG. 2 is a view of a prefabricated structure.

The proposed module of the prefabricated hydraulic structures has the form of a block 1, made in the form of a rectangular parallelepiped, on the upper and lower sides of which, relative to the central axis, recesses 2 are made in the form of rectangles on the left and right, with a hole 3 made in the center of each recess, and opposite on the side to the sides of the block are fasteners in the form of anchors 4.

The proposed module in the form of a block 1 is laid on the shoreline and connected to each other using anchors 4 on the principle of “chain mail”, as shown in FIG. 2. The recesses 2 in the form of rectangles on the upper side of the block 1 perform the function of a “trap” of sand, and then through the holes 3 the trapped sand enters the recesses 2 of the lower side of the block 1, which contributes to the adhesion of the structure to the shore.

Using the proposed module of a prefabricated hydraulic structure, laid down on the principle of "chain mail", it allows to increase operational characteristics and expand the arsenal of shore protection equipment, to obtain a monolithic washable hydraulic structure of a penetrating type with the possibility of increasing the level of the coastline.
