泵站是重要的水利设施,一般情况下为取得稳定的施工结果,会在地基施工中挖掘较深的深度,甚至切入含水层,但是含水层被切断后地下水依然会流动,在压差作用的影响下,地下水会渗入基坑,造成基坑进水、泵站地基不稳等结果。若是泵站所在地区土质较为送算,还有可能在动水压力的影响下出现管涌或流沙现象。为了保障施工安全,施工单位需要采取相应的措施,在施工中给予地下水位以有效的控制。
Pumping stations are important water conservancy facilities. Under normal circumstances, for stable construction results, deep excavations can be tapped in foundation works and even cut into aquifers, but groundwater will still flow after the aquifer is cut off. Under the influence of groundwater seepage into the pit, resulting in foundation pit water, pumping station instability and other results. If the pumping station where the soil is more calculated, there may be under the influence of hydrodynamic pressure pipe or quicksand phenomenon. In order to protect the construction safety, the construction unit needs to take appropriate measures to give effective control to the groundwater level during construction.
