Well sealing method for relief well of foundation pit of subway station
The invention relates to a well sealing method for a relief well of a foundation pit of a subway station. The well sealing method specifically comprises the following steps that S101, a pumping well is inserted into a soil body at the bottom of the foundation pit; s102, a waterproof layer is tightly connected with the dewatering well through a hoop; s103, the bent water stop steel plate is welded to the dewatering well, specifically, the bent water stop steel plate is welded to the outer side of the dewatering well; the bent water stop steel plate is welded firstly, then the influence caused by underground water change in the construction process can be effectively prevented in cooperation with control of the ball valve, the grouting equipment and the water pumping equipment are connected with the water pumping and grouting integrated pipe, and water pumping and grouting can be controlled at any time; after construction is finished, the equipment can be disassembled and reused through a threaded connector; the underground water seepage path is further increased by adopting the bent water stop steel plate different from the common rectangular water stop steel plate, and the safety of well shut-in is ensured by matching the L-shaped laying of the waterproof layer and the hoop reinforcement.
本发明涉及一种地铁车站基坑减压井封井方法，具体包括以下步骤：步骤S101：抽水井插入基坑底部土体中；步骤S102：将防水层通过抱箍与降水井紧密连接；步骤S103：弯折止水钢板与降水井焊接，具体的降水井外侧焊接弯折止水钢板；本发明通过先焊接弯折止水钢板，再配合球阀的控制可在施工过程中有效防止地下水变化带来的影响，注浆设备和抽水设备连接抽水注浆一体管，可随时控制抽水和注浆；施工结束后设备可通过螺纹接口进行拆卸重复利用；采用与普通矩形挡水钢板不同的弯折止水钢板进一步增加了地下水渗流路径，再配合防水层的L型铺设和抱箍加固，保证了封井的安全。
