真空管井复合降水技术的试验分析
摘要:在基坑开挖工过程中,经常会遇到弱透水性的饱和含水层,普通管井降水技术无法对其进行有效疏干,出现的残留水会对基坑安全造成重大影响,特别是地铁暗挖施工的站体及区间隧道。真空管井复合降水技术的新思路能够彻底改变这一局面,它能有效解决粘性土、饱和粉土和界面残留水的疏干难题,大大降低暗挖结构施工的危险性。
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.
