摘要
目前大压力水的降水井封闭一般由专业队伍施工,费用较高。采用大孔降水井封井工法,利用千斤顶压住地下水,用膨胀橡胶止水条填塞钢板与井管间的缝隙,再焊接钢板与导管的横缝,将地下水封在井下。该做法简便易行,经济实用。
At present, sealing of high-pressure dewatering well is usually carried out by professionals and the construction cost is high. Large-aperture dewatering well sealing method could successfully seal the groundwater in well by using jack to press down the groundwater and expansion rubber strip to fill the clearance between steel sheet and well tube before welding the cross joint between steel sheet and pipeline. This is a simple, economic, practical and feasible method.
