【摘要】 研究了在渗入水和层间滞水作为补给的水文地质条件下的基坑降水方法,设计了轻型井点结合明排降水的施工方案,创新地应用了滤水管间隔增减长度法、横插滤水管集水法的工艺措施。实践表明,这些方法成功地解决了上述条件下基坑降水的难题。更多还原

【Abstract】 Aiming at lowering the water table at foundation pit,this paper studies the hydrogeology condition of the infiltration water and water stagnating between the strata. A construction project is designed by combining wellpoint and waterway drain. This has innovated two techniques-"alternately increasing or decreasing the length of well screen" and "gathering the water by breadthwise catheterizing well screen". The engineering practice has proved that these methods successfully solved the problem of lowering the water table at foundation pit in the above condition.更多还原
