Plugging method of dewatering well for ultra-deep foundation pit under water-rich soft foundation condition
The invention discloses the technical field of dewatering well plugging, and particularly relates to a dewatering well plugging method for an ultra-deep foundation pit under the water-rich soft foundation condition. After the water pump in the dewatering well is taken out, the tray and the sealing material are quickly subjected to compression joint sealing treatment through the hooking piece made of field waste steel, glue is injected between the dewatering well and the steel sleeve, the second sealing body is thoroughly pressed on the inner wall of the dewatering well after glue injection, and then the dewatering well is blocked. And finally, the top of the steel sleeve is fully filled with micro-expansive concrete, then full welding and rust prevention treatment are conducted, finally, the dewatering well is thoroughly plugged, foundation construction rich in confined water and large in water return amount can be eliminated, and for the plugging process of the dewatering well in a structural bottom plate rich in confined water mucky soil, through the novel dewatering well plugging technology, the construction period is shortened, and the construction efficiency is improved. Installation can be facilitated, plugging is facilitated after precipitation is finished, the problem of water seepage of the precipitation well reserved hole can be thoroughly solved, and durability is good.
本发明公开了降水井封堵的技术领域，具体为一种富水软基条件下超深基坑用降水井封堵方法。本发明在降水井内部水泵取出后，经过现场废弃钢材制作的钩挂件将托盘和密封材料快速做到压接密封处理，再通过向降水井和钢套管之间注胶，经过注胶后将密封体二彻底压死于降水井内壁上，进而实现降水井封堵，最后将钢套管的顶部在内部注满微膨胀混凝土后进行满焊以及防锈处理，最终将降水井进行彻底封堵，能够消除回水量大的富含承压水基础施工，针对富含承压水淤泥质土的结构底板中降水井的封堵过程，通过新型降水井封堵技术，能够方便安装，降水结束后便于封堵，能够彻底解决降水井预留洞渗水的顽疾，且耐久性好。
