FIELD: construction. ^ SUBSTANCE: method for arrangement of pit sides barriers in saturated soils includes development of at least one row of vertical bearing barrier elements along pit perimetre. In space between vertical bearing barrier elements - pipes, at external side of barrier, soil is artificially frozen by any available method. Arrays of frozen soil in space between the elements should be closed to each other and to vertical bearing barrier elements, besides artificial freezing of soil is done before soil extraction from pit starts, and it is continued until pit backfill is over. ^ EFFECT: improved bearing capacity and stability of barrier, provision of water impermeability for water and soil in barrier. ^ 2 dwg |
