简易轻型井点降水法在苏北工地中的应用

提出一种简易的轻型井点降水施工方法。采用PVC管代替钢管作为轻型降水井点管及导水总管，可用于基坑边坡上降水及坑内降水，也可作为坑底渗水的临时补救措施。该施工方法操作简便、施工迅速、材料消耗少、较为经济等。在苏北某工程的应用实践表明，合理应用该法，可以获得较好的施工效果和经济效益。

APPLICATION OF SIMPLE WELL-POINT DEWATERING SYSTEM IN NORTH JIANGSU PROVINCE

A simple light well-point system is introducted in this paper. PVC pipes are used instead of steel pipes as well point pipes and collecting pipes,to dewater on the slope or in the foundation during the pit excavations,also to solve water leakage from the foundation bottom during the base construction. This system has lots of superiority,such as easy operation, rapid construction,low material consumpion,etc. The application of this method used in a building project in North Jiangsu,shows a good construction effects and ecnomic benefits.
