| Abstract: | 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. |
