摘要:

针对工程实际施工中遇到的单纯采用传统管井降水无法解决特殊地层的降水和无降水作业条件问题,经过摸索、分析和研究,提出了采用管井降水和真空降水相结合的降水施工技术,以解决工程竖井施工问题,结合CRD工法采用洞内水平真空跟进式降水,以解决地面无降水施工条件的问题。

Abstract:

After analysis and study on the problems encountered in dewatering in special stratum that can not be solved by traditional cased well dewatering, the author puts forward the dewatering construction technology that combines the cased well dewatering technology with the vacuum dewatering technology to solve the problems in shaft construction. On basis of CRD tunnel construction method, followup vacuum dewatering is applied to solve the problem that dewatering construction can not be performed on the ground surface.
