Abstract

The invention relates to road construction and can be used to cover sidewalks, pedestrian walkways in squares and parks. The purpose of the invention is to prevent subsidence. Road clothing includes blocks 1 installed on the underlying layer of the soil base, with longitudinal 2 and transverse 3 partitions located in the block cavities, which form cells 4. The lower parts 5 of the transverse 3 partitions are bent at an angle to the surface of the underlying layer. The upper level of the soil filling of the cavities of the blocks is located below the level of the upper ends of the walls of the 6 blocks and partitions, where drainage holes 7 are formed in the walls of the blocks and partitions. The blocks are interconnected with fasteners. 2 hp f-ly, 3 ill.

Description

The invention relates to road construction and can be used to cover sidewalks, pedestrian walkways in squares and parks.

drawdowns. prevention In FIG. 1 shows a pavement block, an axonometric projection; in fig. 2 is a section A-A in FIG. 1; in fig. 3 - mounting unit of adjacent blocks.

Road pavement includes mounted on the underlying layer (not shown) on the underlying layer (not shown) of interconnected blocks 1 with cavities filled with packed soil. The blocks 1 are provided with longitudinal 2 and transverse 3 partitions installed in the cavity, which form cells 4. The lower parts 5 of the transverse 3 partitions are bent at an angle "to the surface of the underlying layer equal to the angle of internal friction of the material of the underlying layer, and the width b of each limb of the transverse 3 partition is determined by the dependence b, de a is the size of the side of the cross section of the cell 4 parallel to the longitudinal partition while the lower parts 5 of the transverse partitions located on both sides of each longitudinal 2 ne egorodki bent relative thereto in opposite directions. Upper soil filling (not shown) cavity; blocks 1 is located below the level of the upper ends of the walls 6 of the blocks 1 and partitions; drainage holes 7 are formed in the walls 6 of blocks 1 and the longitudinal 2 and transverse 3 partitions protruding above the filling level, the bottom of which is located at the filling level. The blocks are interconnected by fasteners 8

The construction of the pavement is performed as follows.

A layer of sandy or sandy soil is spread on the pre-profiled drainage sheet (not shown). Blocks 1 are placed on the underlying layer and combined with each other by means of fasteners 8.

The cells 4 of block 1 are covered with chernozem and seeds of the vegetable layer, compacted by irrigation, and after compaction the ground level should not be higher than the bottom of the holes 7. The bent lower parts 5 of the transverse 3 partitions prevent the blocks 1 from sagging, thereby increasing the carrying capacity of the pavement.
