管道施工排降水在引岗黄水库水工程中的应用

Application of Pipeline-constructing Precipitation in Division Project of Gang Huang Reservoir

本案例为井点降水在河北省石家庄市引岗黄水库水二期工程中的实际应用.在降水方式上通过现场实际确定采用深井、大口径深井井点降水,在方案比选上,采用了井点总数少、井点总进深小、降水周期短、降水费用少的方案,有效地保护了生态环境,加快了施工进度,取得了良好的社会效益和经济效益.

This case is about the application of dewatering in precipitation project of Gang Huang Reservoir in Shijiazhuang City of Hebei Province.Through the way of actual on-site identification in precipitation,we use deep well and large-diameter deep well point precipitation.In terms of the program comparison and selection,we use a program with such qualities as a small number of well points,small deep-into-well points,short period rainfall,low cost of rainfall,which can effectively protect the ecological environment and accelerate the construction schedule,achieving good social and economic benefits.
