浅地下水位条件下的弱性土质基础施工

介绍输电线路工程中,在浅地下水位条件下,管井降水法在砂土、粉土等弱性土质基础上的施工应用。根据500kV漯河至开封输电线路的施工实践,对传统抽水开挖与管井降水法进行功效比较,并从安全质量、施工时间、人力物耗等角度予以分析总结。

Under the high line of underground water,the constructive application about reducing underground water by pipe well in the soft soil foundation,such as sand and power soil etc,used in the transmission line construction are introduced.According to the practice of the transmission line of 500kV LuoHe-KaiFeng,this paper compared reducing underground water by pipe well with ordinary pumping in its efficiency,in the meantime,analysis and generalized in the security and quality,constructive period,work and materials.
