Water-rich depth foundation pit basement dewatering well plugging structure and plugging method thereof
The plugging structure comprises an embedded sleeve arranged outside a dewatering well in a sleeving mode, the embedded sleeve is embedded in a bottom plate of a basement, the lower end of the embedded sleeve penetrates through the bottom plate, and the upper end of the embedded sleeve extends into a sinking groove of the bottom plate; the water stop steel plate is buried in the bottom plate, the water stop steel plate is formed in the middle of the pre-buried sleeve, and the water stop steel plate is arranged in a circle in the circumferential direction of the pre-buried sleeve; the water stop strip is embedded between the root of the water stop steel plate and the embedded sleeve; the cover plate is connected with a connecting sleeve, external threads are formed on the outer portion of the connecting sleeve, the connecting sleeve is screwed to the upper end of the embedded sleeve, the cover plate abuts against the supporting flange of the embedded sleeve, and a sealing gasket is arranged between the cover plate and the supporting flange in a cushioned mode; the tying pieces are tied to the cover plate and the supporting flanges; and the closed concrete is poured into the sinking groove and covers the upper ends of the cover plate and the embedded sleeve. The problem that a traditional dewatering well plugging method is low in one-time plugging success rate is solved.
本发明公开了一种富水深基坑地下室降水井封堵结构及其封堵方法，包括：套设于降水井的外部的预埋套管，埋设于地下室的底板中，预埋套管的下端贯穿底板，预埋套管的上端伸至底板的下沉槽内；埋设于底板中的止水钢板，预埋套管的中部形成有止水钢板，止水钢板沿预埋套管的圆周方向设置一圈；止水条，嵌设于止水钢板的根部与预埋套管之间；盖板，其连接有连接套管，连接套管的外部形成有外螺纹，连接套管螺合于预埋套管的上端，盖板压抵于预埋套管的支撑翼缘，盖板与支撑翼缘之间垫设有密封垫；拉结件，拉结于盖板与支撑翼缘；封闭混凝土，灌注于下沉槽且包覆于盖板和预埋套管的上端。本发明解决了传统的降水井封堵方法存在一次封堵成功率低的问题。
