Abstract

Abstract

During the excavation work, low permeability of the saturated aquifers occurred often, ordinary tube well dewatering cannot drain effectively. And the residual water would bring about significant safe impact to the foundation, especially to the concealed-digging metro station and regional tunnel. Vacuum composite tube dewatering method can drain the residual water ffectively in the clay, saturated silt and aquifer boundaries, and reduce the risk about the hidden excavation structure construction.
