深井井点降水在管沟开挖中的设计与应用

The design and application of the deep well drainage in the ditch excavation

根据工程开挖面积、深度及地质条件,选用了深井井点降水方案,对深井井点降水方案的设计参数进行了计算,对管井构造、施工方法及工艺流程作了介绍,并阐述了其施工控制要点,通过效果评价得出该方案使用效果良好的结论。

According to the excavation area, depth and geological conditions of the construction, the paper choosesthe pattern of the deep well drainage, calculates the design parameter of the pattern for the deep drainage. Besides, the paper also introduces the structure of the tube well, the construction methods and the construction procedure, and indicates the control points for the construction, furthermore, the sound efficiency of the pattern is concluded by the effect evaluation.
