Description

The invention of ognosigs to the treadmill, in particular to the building blocks for covering the slopes of various hydraulic and transport structures.

Strong blocks for hydraulic structures, made in the form of a slab with ribs 1J, are known.

The well-known blocks, as a rule, do not possess the necessary stability, since the coating formed from them is permeable to water, washing away the surface of the slope, which leads to significant deformations of the coating.

The aim of the invention is to increase the stability of the block.

This is achieved by the fact that the ribs are formed on the lateral longitudinal faces of the slab on its lower and upper surfaces and have a length longer than half the slab length.

FIG. . depicts the proposed building block in axomical projection; in fig. 2 - block in three projections; in fig. 3 - section aa of FIG. 2;

in fig. 4 and 5 - a sheeting of building blocks.

The building block is designed as a rectangular plate. On both of its surfaces there are equal in height side-longitudinal ribs 1, starting flush with the ends of the plate and ending behind the middle of the plate, i.e. the length of each edge E is more than half the length of the plate L (, / 2). The shape of the plate allows its use as in the position shown in FIG. 1, and rotated 180 ° relative to the axis О-О (bottom bed up).

Laying slabs in a sandy-gravel preparation begins from the bottom of the escarpment. The plates are arranged so that half of the plate 2 with the ribs protruding from the bottom surface on the slope is below the half of the plate 3 with the ribs protruding upwards. The distance K between the outer side surfaces of the edges of adjacent plates in one row is less than the width of the plate and the quadruple product of the thickness of the ribs1 {K 01 4i).

The slabs of each subsequent row are laid with the same ish-gap to the overlap on the plates of the previous row so that the inner side surfaces of the lower edges of the plates of the overlying row are in contact with the inner lateral surfaces (of the upper edges of the plates of the underlying row. Thus, the space between the upper halves of two adjacent plates of the underlying row, overlaps with half of the slab of the overlying row. At the same time, the longitudinal height of the slab of the overlying row .d is more than half of the plate length L but less than the edge E (t "/ 2) and 4 ontsy upper edges of the lower slabs not perekrshayutssh overlying plates.

Water, psadal on the overlying slope and half of each slab, flows down the tray, with ribs. Water from the underlying half of each plate can flow either lower or lower, or sideways, but in any case it enters the tray on the upper half of the KV1-lnbo from the adjacent plates.

The ribbed plates can have mounting hinges on both flat surfaces to facilitate compression.

The plates can be interconnected, for example, by using bolts through holes in adjacent fins, welding, or other means.

In order to prevent the ground from blowing out holes that are bounded with

The sides of the outer surfaces of the ribs of adjacent plates of one row, the bottom-top bed of the plates of the underlying row and the top-bottom bed of the plates of the overlying row can be covered, for example, with prefabricated parts with bars with a length and height equal to the height of the plate.

When using the proposed building block for slopes of earthworks, water is not allowed to flow from the surface of the coating to the surface of the soil of the slope, the cost of fortification works decreases, the reliability of the coating increases, as even some

the drawdown of the coating does not worsen

His work, as when using other designs.
