Permanent plugging construction method for sewage connecting pipe in canal box
The invention relates to the technical field of underground water pipe blocking treatment, and particularly discloses a permanent blocking construction method for a sewage connecting pipe in a canal box. The method comprises the following steps that a road surface is excavated, soil is covered to the top of the canal box, and a construction window is cut in the top of the canal box; after a construction window is cut out in the top of the canal box, the construction window enters the canal box from the window for underwater operation, and an inflatable air bag is adopted for preliminarily blocking a connecting pipe, so that flowing water in the connecting pipe is in a static state; a cofferdam is built in the canal box, and the cofferdam is located on the upstream of the connecting pipe so as to block incoming water on the upstream of the canal box; a water pumping device is arranged between the cofferdam and the connecting pipe, and accumulated water between the cofferdam and the connecting pipe is discharged through the water pumping device; building a retaining wall corresponding to the connecting pipe in the canal box so as to permanently block the connecting pipe; repairing the window at the top of the channel box to restore the pavement; the construction floor area is small, and the ground and underground pipeline structures of the ground cannot be damaged.
本发明涉及地下水管封堵处理技术领域，具体公开了一种渠箱内污水连接管永久封堵施工方法包括以下步骤：开挖路面及覆土至渠箱顶部，并在渠箱顶部切割出施工窗口；渠箱顶部切割出施工窗口后，从窗口进入渠箱内部进行水下作业，采用可充气气囊对连接管进行初步封堵，使连接管内流水处于静止状态；在渠箱内修筑围堰，围堰位于连接管的上游，以阻断渠箱上游的来水；在围堰与连接管之间设置抽水装置，并通过抽水装置排出围堰与连接管之间的积水；在渠箱内对应连接管修建挡墙，以对连接管进行永久封堵；对渠箱顶部的窗口进行修复，恢复路面；本发明施工占地面积小，不会破坏地面及其地下管线结构。
