Well sealing device and method for pressure-bearing precipitation well
The invention discloses a well sealing device and method for a pressure-bearing precipitation well, and the device comprises a bottom plate which is provided with a bottom plate tongue-and-groove and a fan-shaped waterproof steel plate; the dewatering well casing is provided with a well sealing steel plate, and the side wall is provided with a water stop ring wing; the well shut-in device outer pipe is arranged in the dewatering well pipe in a sleeving manner; the well shut-in device inner pipe is sleeved in the well shut-in device outer pipe, and the lower end of the well shut-in device inner pipe is provided with an inner pipe drainage hole and is limited and fixed through an inner pipe limiting steel plate; the inner pipe water stop strip clamping groove is formed between the well plugging device outer pipe and the well plugging device inner pipe and is provided with an inner pipe water stop strip; the bottom plate steel plate is arranged at the lower end of the sealing device outer pipe and provided with bottom plate water permeable holes, and bottom plate water stop strip clamping grooves and bottom plate water stop strips are arranged at the two ends of the bottom plate steel plate; and the water stop plate is arranged between the bottom plate steel plate and the inner pipe limiting steel plate. The device has the advantages that continuous well plugging is realized, enough time is provided for concrete solidification, and one-time successful well plugging can be ensured.
本发明公开了一种承压降水井的封井装置及方法，包括底板，具有底板企口，设有扇形隔水钢板；降水井井管，设有封井钢板，侧壁设有止水环翼；封井装置外管，套设在降水井井井管中；封井装置内管，套设在封井装置外管中，下端具有内管排水孔，通过内管限位钢板限位固定；内管止水条卡槽，设置在封井装置外管和封井装置内管之间，具有内管止水条；以及底板钢板，设置在封装置外管下端，具有底板透水孔，两端设有底板止水条卡槽和底板止水条；隔水板，设置在底板钢板与内管限位钢板之间。具有实现持续封井，给混凝土凝固提供足够时间，可确保封井一次成功的优点。
