Water-rich stratum tube well dense arrangement dewatering construction method
The invention discloses a water-rich stratum tube well dense arrangement dewatering construction method, which comprises the following steps of: carrying out inrush stability checking calculation according to the actual site condition, optimizing the tube well arrangement, carrying out site measurement and setting out, lowering a protective cylinder as a wellhead, drilling by adopting a slurry wall protection casing method, lowering dewatering tubes section by section through lifting equipment with a guiding function, and carrying out water-rich stratum tube well dense arrangement dewatering construction. The method comprises the following steps: putting a puncher near the bottom end of a downcast pipe, injecting flushing fluid, putting gravel into an annular space between the downcast pipe and a pipe well, filling by using clay in a layered manner, sealing to the ground surface by using original soil, arranging a downcast pipe well branch pipe and connecting the downcast pipe well branch pipe with a drainage main pipe surrounding the edge of a foundation pit, putting a submersible pump, repeatedly pumping water until the pumped water is clean, and trying to pump water. The water level in the well is monitored daily, after precipitation is completed, the submersible pump is shut down and recycled, and a well mouth is plugged. The method is small in occupied space, few in equipment, simple to operate, cost-saving, high in precipitation efficiency and easy to manage.
本发明公开了一种富水地层管井密排布降水施工方法，针对现场实际情况进行突涌稳定性验算，对管井排布进行优化，现场测量放线，下放护筒作为井口，采用泥浆护壁套管法进行钻孔，通过带有导向功能的升降设备逐节下放降水管，将冲孔器下入降水管底端附近，注入冲洗液，向降水管与管井的环空中投入砾料，先用粘土分层填实，再用原土封严至地表，设置降水管井支管并与环基坑边的排水主管连接，下放潜水泵，反复抽水直至抽出的水质洁净，进行试抽水，检修、检查验收，日常监测井中水位，降水完毕后，关停潜水泵并回收，封堵井口。本方法占用场地少，设备少，操作简单，节约成本，降水效率高，易于管理。
