FIELD: construction.
SUBSTANCE: invention relates to construction of underground structures under ground unique and historical objects in complex engineering-geological conditions. Method of underground facilities underworking by underground structure in complex engineering-geological conditions includes device of geotechnical screen. Geotechnical screen is created in the soil along and under the building; at that, bored piles are made along the building to reduce horizontal displacements under the building. Further, horizontal or inclined wells are drilled to inject grouting mortar into soil under the building. Volume of grouting mortar is specified from conditions of compensation of vertical and horizontal soil displacements arising as a result of underworking, to form, after strength, injected grouting mortar resting on boron piles of horizontal covering above underground structure.
EFFECT: technical result consists in reduction of subsidence of ground objects when running under an underground structure, higher safety of construction.
