Dewatering well plugging construction method and dewatering well plugging structure
The invention discloses a dewatering well plugging construction method which comprises the following steps: inserting a dewatering pipe into a dewatering well, and filling a sealing piece between the dewatering pipe and the dewatering well; sleeving the bottom end of the steel sleeve on the top of the downcast pipe, plugging the space between the steel sleeve and the downcast pipe by using waterproof mortar, and dewatering; a cushion layer is laid on the stratum on the periphery of the steel sleeve, a concrete layer is laid on the cushion layer, and a groove to be plugged is reserved in the concrete layer outside the steel sleeve; the downcomer pump is lifted out, and gravel aggregate is filled into the downcomer; after no water return is checked, accumulated water in the steel sleeve is completely drained, and then the steel sleeve is filled with anti-seepage concrete; the top of the steel sleeve is covered with a concave steel holding plate; if water leaks and flows back, a hole is formed in the downcast pipe through the valve body, and cement double-liquid slurry is injected into the hole; and the to-be-blocked groove is filled with impervious concrete. The invention further discloses a dewatering well plugging structure. According to the dewatering well plugging construction method and the dewatering well plugging structure, potential quality hazards are avoided in the well plugging process, construction is easy to operate, and the problem of well plugging water burst can be effectively solved.
本发明公开了一种降水井封堵施工方法，包括：将降水管插入降水井中，在降水管与降水井之间填充密封件；将钢套管底端套于降水管顶部，钢套管与降水管之间用防水砂浆塞堵，降水；在钢套管外周地层上铺设一层垫层，在垫层上铺设混凝土层，在混凝土层于钢套管外预留待封堵凹槽；降水泵提出，将砂石骨料填入降水管中；检查无反水后，排干净钢套管内积水，再填入抗渗混凝土；在钢套管的顶部加盖凹形钢扪板；若渗漏反水，通过阀体向降水管内开孔作业，向孔内注入水泥双液浆；采用抗渗混凝土填实待封堵凹槽。还公开了一种降水井封堵结构。本降水井封堵施工方法及降水井封堵结构井封堵过程不留质量隐患且施工易于操作，能有效解决封井涌水问题。
