Tube well dewatering combined reducing steel sleeve plugging construction method
The invention discloses a tube well dewatering combined reducing steel sleeve plugging construction method, and relates to the technical field of foundation pit engineering. The tube well dewatering combined reducing steel sleeve plugging construction method comprises the following steps that starting is carried out, a construction period is calculated, and a construction progress plan is compiled; construction preparation is carried out, and construction management personnel, construction materials and construction machines enter the site; water is pumped; the pump is started; cushion layer pouring is carried out; the combined reducing steel sleeve is manufactured; a casing pipe is mounted; a small guide pipe is mounted; core filling concrete is poured through a small guide pipe method; a simple flange is manufactured; waterproof construction is carried out on the bottom plate; bottom plate concrete pouring is carried out; a basement wall top plate is poured; the tube well is blocked; and construction is finished, and inspection and acceptance are carried out. According to the tube well dewatering combined reducing steel sleeve plugging construction method, a dewatering tube well is plugged layer by layer, the advantages of effectively blocking underground water and gas and ensuring the plugging quality are achieved, and the problem that plugging fails due to the fact that at present, construction is difficult, the plugging effect is poor, and the underground water and gas cannot be effectively blocked is solved.
本发明公开了一种管井降水组合式异径钢套管封堵施工工法，涉及基坑工程技术领域，包括：开始，计算工期，编制施工进度计划；进行施工准备，施工管理人员、施工材料和施工机械进场；进行抽水；进行起泵；进行垫层浇筑；进行组合式异径钢套管制作；进行套管安装；进行安设小导管；进行小导管法浇筑填芯混凝土；进行制作简易法兰；进行底板防水施工；进行底板混凝土浇筑；进行地下室墙顶板浇筑；进行管井封堵；结束施工，检验验收。该管井降水组合式异径钢套管封堵施工工法对降水管井进行层层封堵，实现对地下水气的有效阻断，确保封堵质量的优点，解决了目前施工困难，封堵效果较差，不能实现对地下水气有效的阻断，导致封堵失败的问题。
