METHOD OF CONSTRUCTION OF UNDERGROUND WORKINGS IN UNSTABLE WATER-SATURATED GROUNDS

摘要

FIELD: construction, particular, methods of construction of underground workings in unstable water-saturated grounds. SUBSTANCE: method includes establishment of ice-ground guard and driving of underground working with installation of support. The method is distinguished by the fact that ice-ground guard is defrosted along the axis of underground working by parts multiple to length of lining ring, then, thawed incoherent ground is solidified by injections by separate parts. EFFECT: higher efficiency. 1 dwg
