复合沉井法在某变电站集水池施工中的应用

Application of compound caisson method in construction of collecting basin in a substation

青岛地区某变电站集水池施工受场地周边建筑物和水文地质条件影响,采用沉井法和轻型井点降水相结合的复合沉井法施工。根据地下水位确定井点降水方案,制作集水池刃脚,挖砂下沉,过程沉降把控,为今后类似工程施工提供借鉴和参考。

The construction of collecting basin in a substation in Qingdao area is influenced by the surrounding buildings and hydrogeological conditions,the compound caisson method combining caisson method with light well point precipitation is adopted. The scheme of well point dewatering is determined by the groundwater level,making the edge foot of the collecting basin,the sand is dug down and the process of settlement is controlled,which can provide reference for the similar engineering construction in the future.
