管井降水技术在西安地铁施工中的应用

The Application of Tube Well Dewatered Technology in the Subway Construction in Xi'an

地下工程施工在遇到高水位时,经常会采取降水以确保施工的安全顺利进行。介绍了工程概况,结合西安地铁2号线南段三爻至凤栖原暗挖区间的工程地质与水文地质特性,阐述了管井降水方案的选择及降水设计细节,讨论了管井降水的施工问题。

In the case of high water-level in the construction, dewatering measures are often adopted for ensuring the safe and smooth operation of the construction. This paper introduces the general situation of the project, and connecting with the engineering geological and hydro-geological characteristics of Sanyao-Fengqiyuan Subsurface Excavation Section in the south section of No.2 Line of Xi＇an Subway, expounds the selection of tube well dewatering schemes and some details of dewatering design, and discusses some problems of the construction of tube well dewatering.
