气动降水与轻型井点组合降水方案研究

Study on the Combination of Pneumatic Well-Point Dewatering and Light Well-Point Dewatering

通过研究气动降水与轻型井点组合降水工法,给出该工法井点埋置深度、井点数量与间距的确定方法,以示例的方式给出通用布置方案,并应用于山东省滨州市某项目作为工程实例。研究分析了该布置方案的降水效果,突出了该组合降水井相比传统的止水帷幕降水工法,止水效果好、节能降耗效果突出的优点,总结出了一种气动降水与轻型井点组合降水井设计方案的确定方法。

Through the study of combination of pneumatic well-point dewatering and light well-point dewatering.By studying the calculation of the depth,length and number of the well,we conclusion an arrangement of this well-point dewatering.And this arrangement applies to aproject located in Binzhou,Shandong Province.We think this well-point dewatering works better and more environment friendly than water proof curtain.In a word,we design an arrangement of the combination of pneumatic well-point dewatering and light well-point dewatering.
