Well sealing structure of dewatering well and construction method of well sealing structure
The invention provides a well sealing structure of a dewatering well and a construction method thereof, aims to solve the problem that the well sealing structure of the dewatering well is easy to leak in the later period, and relates to the technical field of water prevention. The well sealing structure of the dewatering well comprises a concrete bottom plate and a dewatering well pipe penetrating through the concrete bottom plate, a sleeve is embedded in the concrete bottom plate, the dewatering well pipe is sleeved with the sleeve, the upper end of the sleeve is lower than the upper surface of the concrete bottom plate, and a groove containing the upper end of the sleeve is formed in the upper surface of the concrete bottom plate. A water stop ring embedded in the concrete bottom plate is arranged on the sleeve in a sleeving manner; a plugging cavity used for plugging a dewatering well casing is formed in an inner cavity of the casing pipe, well casing filling micro-expansion concrete is arranged in the plugging cavity, a cover plate matched with the casing pipe in a sealing mode is arranged at the upper end of the casing pipe, and the groove is filled with bottom plate pipe well sealing micro-expansion concrete covering the cover plate. The waterproof effect is good, the problem that a well sealing structure of the dewatering well leaks easily in the later period is solved, and construction is easy and convenient.
本发明是提供一种降水井封井结构及其施工方法，以解决降水井封井结构后期易渗漏的问题，涉及防水技术领域。降水井封井结构，包括混凝土底板和穿过混凝土底板设置的降水井管，所述混凝土底板内埋设有套设在降水井管上，且上端高度低于所述混凝土底板的上表面高度的套管，所述混凝土底板的上表面设有将套管的上端包括在内的凹槽，所述套管上套设有埋设在混凝土底板内的止水环；所述套管的内腔形成用封堵降水井管的封堵腔，所述封堵腔内设有井管填充微膨胀混凝土，所述套管上端设有与套管密封配合的盖板，所述凹槽内填充有将所述盖板盖住的底板管井封口微膨胀混凝土。本发明防水效果好，解决了降水井封井结构后期易渗漏的问题，且施工简便。
