轻型井点降水在浅滩桥梁承台基坑开挖中的应用

Application of Light Well-point Dewatering in Excavation of Base Slab Pit of Bridge in Shoal

以某大桥使用轻型井点法、成功解决浅滩粉砂土层桥墩承台深基坑降水问题为例,阐述了轻型井点降水法的方案设计、方案实施,为类似工程基坑降水施工提供了借鉴经验。

Taking the light well-point method used in a bridge successfully to solve the deep pit dewatering problem of pier base slab in the silt soil stratum of shoal as an example,the article sets forth the scheme design and the scheme implementation of light well-point dewatering method,which provides the experience referred for the similar engineering pit dewatering constructions.
