由于调节池、辐流式沉淀池(2座),距离河岸较近,地下水位高,已无法进行上述水池的基础施工。施工单位经研究,采用井点降水的施工方法,根据地层概况及施工要求,考虑到涌水量、地层及抽排水时间等因素,尽可能达到较理想的排水效果,根据井径与涌水量的关系,井径设计为350mm,下入300井壁管及滤水管成井,滤水管必须下至地下静水位以下。
Due to the regulation pool, radial flow sedimentation tank (2), close to the bank, the groundwater level is high, has been unable to carry out the foundation construction of the above-mentioned pool. According to the survey and well construction method, according to the general conditions and construction requirements of the strata and the factors such as water inflow, formation and pumping drainage time, the construction unit will try its best to achieve the ideal drainage effect. According to the relationship between well diameter and water inflow Well diameter design for the 350mm, into the next 300 wells and drainage pipe into the well, the filter must be below the underground water level below.
