The invention relates to hydraulic engineering and road construction and can be used to protect the slopes of land structures and coasts from the effects of waves and currents.

The purpose of the invention is to increase the reliability of ensuring the removal of water from the under-slab space and reducing the labor intensity for its construction.

Figure 1 shows the anti-wave mount, plan; figure 2 - section aa in figure 1.

The anti-wave mount consists of monolithic concrete slabs 1, reinforcing bars 2 with bitumen-coated ends 3 passing through seam 4. The seam contains synthetic fiber material (geotextile) in the form of a loop 5, the free ends 6 of which are bent to the edges of adjacent plates and placed them. The mount is laid on the slope 7 of the dam or dam, made of ground material.

Monolithic reinforced concrete plates 1 of the fastening, laid-on the slope soil 7, are interconnected in the places of temperature-expansion joints with reinforcing bars 2 installed alternating in adjacent plates, the ends of 3 reinforcing bars are coated with bitumen and recessed into adjacent plates to a depth up to 30-40 diameters of rods. This eliminates the upsetting of the plates relative to each other, and the coating with bitumen allows for thermal deformations and eliminates cracking.

the free ends of the loop is determined from the ratio

where d is the thickness of the fibrous synthetic material, such as geotextile; Kg - geotextile filtration coefficient;

Ko is the filtration coefficient of the soil of the dam body.

In this case, the seams (joints) have absolute soil resistance. but retain poor water permeability, making the slope drained. The screening effect of fastening allows to preserve the stability of the slab coating during a sharp drawdown of the reservoir, increasing the reliability of the proposed anti-filtration coating.
