Large basement dewatering well plugging method
The invention discloses a large basement dewatering well plugging method, which belongs to the technical field of dewatering well plugging, and comprises the following steps: a steel sleeve with a water stop ring is sleeved on the upper part of a dewatering tube well, a polymer self-adhesive film waterproof coiled material is firstly paved on the edge of a groove, then a 2cm * 3cm water swelling water stop strip is embedded and filled, foundation raft concrete is poured on the outer side, and foundation raft pouring is completed. A blocking step: pouring micro-expansion impervious concrete to form a first waterproof layer; a water-stopping circular plate is tightly attached to the micro-expansion impervious concrete for plugging, so that a second waterproof layer is formed; high epoxy resin sealant with the depth of 5cm is poured into the upper part for plugging to form a third waterproof layer; a sealing cover plate and the sleeve with the water stop ring are locked through bolts, a rubber sealing gasket is arranged between the steel sleeve with the water stop ring and the sealing cover plate, and a fourth waterproof layer is formed; and finally, the sealing cover plate is wrapped with waterproof mortar, pouring is conducted to be flush with the foundation raft, and a fifth waterproof layer is formed. The technical problems of leakage plugging and poor secondary plugging effect are solved.
本发明公开了一种大型地下室降水井封堵方法，属于降水井封堵技术领域，包括套接在降水管井上部的带止水环钢套筒，先将高分子自粘胶膜防水卷材铺贴至凹槽边，再嵌填2cm*3cm遇水膨胀止水条，外侧浇筑基础筏板混凝土，基础筏板浇筑完成，封堵步骤：浇筑微膨胀抗渗混凝土，形成第一道防水；再紧贴微膨胀抗渗混凝土安装有止水圆板封堵，形成第二道防水；上部灌入深度为5cm高环氧树脂密封胶封堵，形成第三道防水；后用密封盖板与带止水环套筒用螺栓锁紧，带止水环钢套筒与密封盖板之间设有橡胶密封垫，形成第四道防水；最后用防水砂浆将密封盖板包覆，浇筑同基础筏板齐平，形成第五道防水。本发明解决了封堵渗漏且二次封堵效果较差的技术问题。
