Abstract

The invention relates to hydraulic engineering and road objects, specifically to anti-erosion coatings. The purpose of the invention is to increase the stability and reliability of the coating by reducing soil removal through the gaps, reducing the consumption of materials and the complexity of its installation. The rectangular plate is provided on one of its two planes with a longitudinal 1 and transverse 2 ribs arranged in the shape of a letter T. The plates are laid in a covering at a height of two. Rusa with the arrangement of the edges of the plates 6 of the upper Rus in the gaps of the plates 5 of the lower Rus. At the same time, the longitudinal edge of the plate 6, located in the gap between the plates 5, divides the rest of it into two more narrow gaps 7, covered from above with the near-edge part of the plate 6. The transverse edge 2 of the same plate 6 blocks the straight flow of the jets of flow from narrow gaps 7, causing rotation and collision of opposing jets from each pair of adjacent gaps 7, the same happens in gaps 8 between the edges of the plate 6 and the longitudinal edge I of plate 5, where. in addition, superposition occurs with the intersection of the upper jets on the lower ones, a positive decrease in the erosion rates in the extended overall places 9 of the mating of the plates with clamps. The presence here of counter-flow overhangs of the plate 6 in front of its transverse edge 2 prevents the removal of suspended particles of the soil. The plates are joined by collars 10 in the directions of the longitudinal ribs 1 of the plates 5 behind the loops 3 and in the intersections of the directions of the longitudinal edges I of the plates 6 with the directions of the transverse ribs 2 of the plates 5 behind the loops respectively 3 and 4. 3 Il.

FIG. I shows the stove, a general view; in fig. 2 - plate size along the height and width of the floor, a section according to the size of the sheet outside the 11 e fin; in fig. 3 - placement and association of coating plates, plan view.

The plate (Fig. I) of the rectangle is provided on one of its two planes with a longitudinal 1 and transverse 2 ribs. The ribs at the ends are extended with loops 3 and 4, embedded in the slab to allow the hinge assembly of the plt to the floor with clamps. Petlp in the transverse rib are made in half of the total number of plates. The plates along the thickness of the coating (Fig. 2) are placed in two Rus so that the longitudinal (along the stream) gaps between the plates 5 of the lower rus and their lengths transversely upward. The ribs 1 are covered with plates 6 of the upper rus, the longitudinal edge of each of which facing down and, located in the longitudinal m gap between the plates 5, divides the remaining part of the floor into even narrower two gaps 7, which are covered from above by the lower part of the plate 6, and the transverse edge 2 of the same upper plate blocks the straight jets flow (shown in Fig. 2 dotted with arrows from narrow gaps 7, causing turning and colliding of opposite gaps from each pair of adjacent longitudinal gaps 7 between the side faces of the plastics 5 and the longitudinal edge of the plate 6, similarly, and in the gaps 8 between the faces of pl | b and the longitudinal edge of the plate 5, in addition, there is an overlap with the intersection of the upper jets (shown in
