Waterproof casing pipe structure of dewatering well point and construction technology of waterproof casing pipe structure
The invention discloses a waterproof sleeve structure of a dewatering well point and a construction technology of the waterproof sleeve structure, and belongs to the field of basement waterproofness, the waterproof sleeve structure comprises a waterproof sleeve, the outer side of the waterproof sleeve is provided with a waterstop ring and annular reinforcing steel bars, and the annular reinforcing steel bars are arranged on the two sides of the waterstop ring respectively; an annular opening is formed in the upper end part of the waterproof sleeve, a plurality of groups of upper connecting holes which are distributed at equal intervals are formed in the annular opening, bolt columns are mounted in the upper connecting holes, and bolt bodies of the bolt columns are arranged upwards; a flange blind disc is detachably arranged at the upper end of the waterproof sleeve, a connecting hole is formed in the flange blind disc, the lower connecting hole is matched with the upper connecting hole and is suitable for being connected with a bolt column, and a locking nut is installed at the upper end of the bolt column and is suitable for closing the flange blind disc on the waterproof sleeve. The problems that existing tube well plugging construction is difficult, the plugging effect is poor, the plugging cost is high, later maintenance is difficult, and inconvenience is brought to use of a user are solved.
本发明公开了一种降水井点的防水套管构造及其施工工艺，属于地下室防水领域，包括防水套管，所述防水套管的外侧分别设置有止水环和环形钢筋，所述环形钢筋设置有多组且分别设置于止水环的两侧，所述防水套管的上端部设置有环形口，所述环形口上开设有多组等间距分布的上连接孔，所述上连接孔内安装有螺栓柱，且螺栓柱的栓身向上设置；所述防水套管的上端可拆卸有法兰盲盘，所述法兰盲盘上开设有连接孔，所述下连接孔与上连接孔相适配并适于螺栓柱相连接，所述螺栓柱的上端安装有锁紧螺母适于闭合法兰盲盘在防水套管上。本发明解决了现有的管井封堵施工难度大、封堵效果不好、封堵成本高、后期维修难给使用者的使用带来不便等问题。
