FIELD: construction industry. ^ SUBSTANCE: block used for building of wall that is made of several similar blocks overlapped in a staggered manner without gaps. Block is made in the form of an element with longitudinal profile and has top surface, bottom surface and two side surfaces. Generally, cross section of block is made in the form of a cavity broadening downwards. On top surface of block there is longitudinal centre protrusion that rises above sides of the surface so that left-handed supporting slope and right-handed supporting slope are formed. Construction of top and bottom surfaces is provided so that when a block is being overlapped with a similar block from below for the purpose of wall building, top surface of lower block is connected to bottom surface of upper block, and left-handed and right-handed supporting slopes are used as blocking elements for mutual blocking of vertical adjacent blocks. Blocks are of such shape and size that at vertical joining of three similar blocks, vertical distance from top of protrusion of the lowest block to bottom of the highest block turns out to be less than 1/3 of height of one block. There described as well is a group of blocks for wall building, and wall built of such blocks. ^ EFFECT: preventing leakages in walls used in underground structures, wall water retaining, and preventing soil washing out. ^ 18 cl, 103 dwg |
