Well sealing method and structure of basement dewatering well
The invention discloses a well sealing method and structure of a basement dewatering well. The method comprises the steps that a dewatering well pipe is cut to the position above a cushion layer; a well sealing lower cover is installed on the dewatering well pipe, a side sealing pipe and a sealing plate of the well sealing lower cover are installed on the dewatering well pipe and arranged on the cushion layer, the upper end of the side sealing pipe is not smaller than the elevation of the upper surface of the bottom plate, and a water stopping plate of the well sealing lower cover is located in the center of the bottom plate; a water pumping pipe in the dewatering well pipe extends out of the inner drainage pipe; a waterproof coiled material is laid on the cushion layer, and the waterproof coiled material is turned upwards and extends to the side sealing pipes; constructing a bottom plate; after construction of the basement structure is completed, the water pumping pipe is pulled out or cut, a well sealing upper cover is installed on the inner discharging pipe and comprises a pipe body and a top plate, the pipe body and the top plate are installed on the inner discharging pipe, the upper surface of the top plate is made to be lower than the upper surface of a bottom plate in elevation, and the pipe body is arranged on a sealing plate and/or the inner discharging pipe; and a concrete closed body is formed in the hole of the bottom plate. The sealing performance of the dewatering well casing can be improved, and a well sealing structure is prevented from being oxidized or corroded.
本发明公开一种地下室降水井的封井方法及构造，该方法包括将降水井管切割至垫层上方；在降水井管上安装封井下盖，使封井下盖的侧封管及封板安装在降水井管上并设置在垫层上，使侧封管的上端不小于底板的上表面标高，使封井下盖的止水板位于底板的中心；将降水井管内的抽水管从内排管内伸出；在垫层上铺设防水卷材将其上翻延伸在侧封管上；施工底板；在地下室结构施工完成后，拔出或者切割抽水管，在内排管上安装封井上盖，所述封井上盖包括安装在内排管上的管体及顶板，使顶板的上表面低于底板的上表面标高，将管体设置在封板和/或内排管上；在底板的洞口内形成混凝土封闭体。本发明能够提高降水井管的密封性能，防止封井构造氧化或被腐蚀。
