MULTI-COMPONENT BLOCK OF RETAINING WALL Russian patent published in 2015 - IPC E02D29/02 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to erection of a retaining wall from blocks. A mortarless retaining wall formed by a row of composite blocks of the retaining walls laid onto each other in rows, besides, each block comprises a face module with a front facet forming a part of the visible surface of the retaining wall. The face module is equipped with two elements of a lock device. An anchor module with two elements of the lock device, in their shape coupled with elements of the lock device of the face module. The anchor module is in contact with soil, which is retained by the retaining wall. The anchor module and the face module have upper and lower support planes, besides, the upper support plane is matched with the lower support plane of the above laid block, support planes are mainly arranged as flat, capable of resisting shifting forces between adjacent blocks, shifting forces arise from the action of soil at the block retained by the retaining wall. The anchor module and face module are engaged by means of appropriate elements of the lock device to form a block, besides, the anchor module and the face module, being engaged, form a hollow volume limited by inner walls of the anchor module and the face module, which stretches along the vertical line from the upper support plane to the lower support plane. Engagement of elements of the lock device of each anchor module and each face module is untight, permitting limited relative shifts between the specified anchor module and the specified face module without damage to engagement.

EFFECT: provision of stability of a retaining wall, increased bearing capacity.
