Well sealing construction method for dewatering well
The invention relates to the technical field of building construction, in particular to a precipitation well shut-in construction method which comprises the steps that a precipitation tube well is formed, a water pump is placed to pump water outwards, a prefabricated sleeve is installed at a wellhead of the precipitation tube well, after the water level is lowered to a proper position, the precipitation tube well is filled with a gravel layer, and a grouting layer is poured above the gravel layer to the wellhead of the precipitation tube well. And when the solidification strength of the grouting layer reaches a proper value, the water pump stops pumping water, meanwhile, a cementing material is poured into the water pipe through high-pressure equipment, and when the solidification strength of the cementing material reaches a proper value, the water pipe and the power supply cable are cut off on the surface of the grouting layer, and a grouting filling layer is poured into the prefabricated sleeve. The continuous working state of the water pump in the well plugging process is set, so that well plugging of the downcast tube well in the states of high water level of underground water and the like can be completed more simply, time and resources consumed by a large amount of water pumping during common well plugging are saved, and the construction cost is saved.
本申请涉及建筑施工的技术领域，具体是一种降水井封井施工方法，包括开设降水管井并放置水泵向外抽水，在降水管井井口处安装预制套筒，水位下降至合适位置后，向降水管井内填充碎石层，在碎石层上方浇筑灌浆层至降水管井井口，灌浆层凝固强度达到合适值时，水泵停止抽水，同时通过高压设备向水管内灌注胶凝材料，胶凝材料凝固强度达到合适值时，在灌浆层表面处切断水管与供电电缆，在预制套筒内灌注灌浆填充层。本申请通过设置水泵在封井过程中的持续工作状态，使得地下水高水位等状态下的降水管井可以较为简单地完成封井，节省了普通封井时大量抽水耗费的时间与资源，节省了施工成本。
