FIELD: construction.
SUBSTANCE: method for construction of an underground structure includes formation of two rows of fencing elements in soil between the erected structure and the existing one, and one of these rows is made in the form of an interlocking fence for the depth that is not less than the depth of the erected structure, and assembly of the erected structure under protection of the fencing elements. The second fencing element is installed along the external contour of the erected structure and is also made in the form of the interlocking fence for the depth equal to the depth of the first fencing element, and as the soil is being mined, the fencing elements are tightened with each other by anchors, at the same time the anchors are arranged at different angles to the planes of the fencing elements.
EFFECT: improved quality of construction, higher resistance to bending and resistance to displacement of fencing elements in direction of a prepared pit.
