FIELD: construction.
SUBSTANCE: method to reinforce foundation pit and trench boards includes arrangement of a rigid L-shaped structure made as a vertical retaining wall with a collar protruding towards the foundation pit fixed along the wall top, soil working in the foundation pit, installation of anchors and their tensioning. At first anchors are installed on the collar and tensioned, besides, anchors are installed in direction parallel to wall reinforcement, and value of anchors tension is maintained at the calculated level, reinforcement movement start is recorded, afterwards soil is worked in the foundation pit (trench).
EFFECT: neutralisation of impact from compressed pressure and putting reinforcement in operation before soil working in foundation pit, exclusion or minimisation of horizontal displacements of the wall, increased bearing capacity of soil massif.
