SUBSTANCE: invention relates to hydraulic engineering construction, namely to the design of channel linings, and can be used primarily in the construction and reconstruction of open channels with reinforcing the slopes and the bed formation. Anti-filtration lining of the channel of a meliorative structure consists of polymer-sand concrete and is made in the form of n-shaped or v-shaped blocks.

Description

The invention relates to hydraulic engineering, in particular to the design of the lining of the canals, and can be used mainly in the construction and reconstruction of open channels with fastening slopes and the formation of the channel.

Known antifiltration coating of channels, which includes a non-porous preparation laid on a prepared base, on the surface of which a waterproofing layer is laid, on top of which a lining of concrete or reinforced concrete slabs, or monolithic concrete, or reinforced concrete with expansion joints is laid. Along the perimeter of the channel, anti-caking preparation is made of different thickness and multi-layer, while the heat-conducting layers are laid in the upper part of the anti-caking preparation. The minimum, below the lower water line in the channel, and the maximum, above the upper water line in the channel, the thickness of the anti-porous preparation under the lining is determined by mathematical dependencies (RF patent No. 2284390, publ. September 27, 2006).

The disadvantages of this technical solution are the design complexity, which consequently leads to large labor costs associated with the implementation of a multilayer, multi-thickness anti-porous water treatment; low maintainability with a fairly high cost.

A device for fixing the surface of the reclamation channel, consisting of a layer of filtering material in contact with the surface and a layer of fastening material passing through the water, located on it, characterized in that in order to reduce the cost of fixing and mechanize the process of its implementation, it is made in the form of a two-layer reinforced concrete block laid on the channel surface the side of which is in contact with the surface of the channel is made of porous concrete, and the opposite side is made of dense concrete having water passage openings passing through it (patent SU No. 1142593 A, publ. 02.28.1985).

The disadvantages of such a cladding device are low strength, difficult to fasten the plates together, the susceptibility to destruction under the influence of its own weight during loading and transportation.

Known antifiltration clay clay screen, including a clay layer crumpled or in the form of a paste and a protective layer of soil, while the clay layer is made with a surface area hardened by rubble or gravel, and the protective layer of soil is made of sandy loam soil. In the second embodiment, the protective soil layer is made of incoherent soil (RF Patent No. 78226, publ. 20.11.2008).

The disadvantages of this solution of the anti-filter screen are the large amount of earthwork, the difficulty of performing a uniform coating of the same thickness, low operational reliability and short life of the structure due to rupture of the surface layer by plants, earth-moving animals, and also as a result of seasonal temperature fluctuations (heating - cooling, freezing - thawing) and humidity (moistening - draining).

A known block for the construction of a hydraulic structure, having the form of a multifaceted body, with rectangular faces, a protrusion and a groove (RF patent No. 53686, publ. 27.05.2006).

The disadvantages of this block are low strength and lack of stability due to the execution of the block in the form of a tetrahedral parallelepiped, in addition, the implementation of the fastening of the blocks together requires mechanization, thereby complicating the installation.

The essence of the proposed technical solution consists in creating the design of the anti-filtration lining of the channel of the reclamation facility using composite polymer sand blocks and trays reduced to the smallest number of sizes, grades and shapes (unification, uniformity) to simplify installation work and reduce the construction time for a reliable structure and eliminate irrigation water losses to filter.

The technical result of the proposed solution of the antifiltration lining of the channels is to increase the installation speed with ease of construction, increase the durability of the construction and save irrigation water.

The technical result is achieved by the impervious lining of the channel with polymer sand blocks-trays laid on the prepared base with the formation of transverse seams. The efficiency of using unified blocks and the reliability of docking connections can significantly reduce the construction time of a reclamation facility while reducing the complexity and cost of work. The unification of building blocks and their sizes provide the possibility of rapid transportation by road, and if necessary, dismantling and moving to a given area (for example, when changing the channel of the channel).

An essential feature of the claimed invention is the impervious lining of the channel of the reclamation structure, consisting of composite blocks-trays made in the form of p-shaped or v-shaped blocks of polymer sand, 0.15 m thick, 0.5-2.0 m long, 1 wide , 0-2.0 m. The tightness of the connection of the blocks to each other in the places of transverse joints is provided by a thorn-groove connection, for a better connection of the blocks a rubber gasket or various sealing compounds applied to the joint are used unit installation.

The invention is illustrated by drawings, where in FIG. 1 shows a block tray in a perspective view; FIG. 2 is a cut-out fragment of a channel lined with blocks-trays, in FIG. 3 shows a top view.

Impermeable lining of the channel, consisting of composite blocks-trays having the shape of a tray, consisting of lower 1 and upper 2 faces, vertical front 3 and rear 4 faces, horizontal surface 5 and bottom 6 (see Fig. 1). On the vertical front face 3 there is a protrusion in the form of a head along the entire surface. On the vertical rear face 4, a groove is made in the form of a head along the entire surface. Two polymer-sand block-trays are connected together by means of a thorn-groove lock, forming a rather rigid and tight design.

The claimed technical solution in the form of an impermeable lining of the channel with block-trays can be reproduced industrially, which meets the criterion of "industrial applicability".

Using the proposed block-tray for forming the channel channel of the reclamation facility will increase the durability of the work, operational characteristics and simplify the process of erecting the reclamation structure, which will significantly reduce the complexity of the work.
