PROCESS OF CONSTRUCTION OF TUNNELS IN SOFT WATER-SATURATED GROUND

摘要

FIELD: construction industry. SUBSTANCE: soft water-saturated ground in removed from within the limits of inclined tunnel and replaced with concrete with formation of continuous pillar of necessary thickness along its outer outline. Pillar provides for protection against penetration of floating earth and ground water. Then section beyond formed pillar is filled with material having lesser density. Material with lesser density is used to fill section within which limits tunnel with erection of permanent lining in case of necessity is driven. EFFECT: increased efficiency and reliability of tunnel driving. 2 cl, 2 dwg
