The invention relates to water construction, and specifically to devices for protecting soil slopes of canals, banks of rivers and reservoirs from the destructive action of wavebreaking, currents and other factors, as well as slopes in the downstream water control structures,.

The purpose of the invention is to increase the reliability and reduce the material of fastening.

This goal is achieved by the fact that the connection of reinforced concrete slabs made in the tongue-and-groove lock with reinforced concrete elements having an I-shaped cross-section.

Figure 1 shows the slope with the mounted mount, section; figure 2 - the same plan; fig.Z - node I in figure 2; figure 4 - plate; in figure 5. - section aa in figure 4.

The fastening consists of reinforced concrete slabs 1 with a trough-shaped shape with grooves on the ends and reinforced concrete coupling elements 2, having an I-shaped cross-section, placed on the protected slope 3. A concrete stop 4 is installed for the fastening device to prevent the plates from slipping along the slope, then driving half of the elements of the I-form are laid in it, and after that, reinforced concrete slabs are laid half the length of the blocks, 1, thus forming a tongue-and-groove lock with the latter. In the future, the entire element 2 of the bond with half the length of the slide, etc., fits into the free face of plate 1. The plates 1 and the elements 2 of the connection are laid perpendicular to the water edge in

reservoir (channel), with the formation of longitudinal chambers in which the communication elements 2 are placed. The latter are made in the form of longitudinal strips installed parallel to the coastline.

To prevent soil penetration between the slabs 1, staff seams are arranged. Fig. 3 shows an example of such a seam, where a reinforced concrete beam 5- is laid under the plates, can also be laid instead of a reinforced concrete beam and tarred boards.

15 To remove the weighing pressure of water in the plates 1, holes (cells) 6 are arranged, which are subsequently filled with gravel material. In the case when the protected slope is composed of structurally unstable soils, then a continuous reverse filter is arranged under the fastening plates.

Claims (1)

Claim 25 Fastening channel slopes, including reinforced concrete slabs, interconnected in a ground lock with. using coupling elements with an I-shaped cross-sectional shape, which is characterized by the fact that, in order to increase reliability and reduce material consumption, reinforced concrete slabs are made of trough-shaped 35 with grooves on the ends and installed on the slope with the formation of longitudinal chambers in which the communication elements are arranged, made in the form of longitudinal strips of variable cross-section along the height, 40 forming the closing profile of the chambers and arranged parallel to the coastline with a shift in terms of the trough-shaped plate. 1486553 t ~ t mr one one "TO ₇ 1 Τ one 'I I i I t \ one one one one one | one one one ! one ί one one | one one one - + ! one I g one one one one one I I I T 1 !
