Water bag plugging structure of underground diaphragm wall joint and construction method of water bag plugging structure
The invention relates to the technical field of diaphragm wall joints, in particular to a diaphragm wall joint water bag plugging construction method which comprises the following steps that S1, a pair of I-shaped steel is placed on the two sides of a groove correspondingly, a reinforcement cage is placed between the I-shaped steel, and the position and stability of the reinforcement cage are ensured; s2, the filling water bag is placed in a notch, away from the reinforcement cage, of the I-shaped steel; s3, one end of a Y-shaped pipeline is connected to a water outlet of the water pump, and the other two ports of the Y-shaped pipeline are connected to the first pipeline and the second pipeline of the outer bag and the inner bag through a first valve and a second valve correspondingly; s4, opening a water pump, and starting to inject water into the outer bag and the inner bag; s5, the reading of the water pressure detector is observed, and it is ensured that the water pressure is within the normal range; and S6, if the water pressure is suddenly reduced, the outer bag is damaged. At the moment, the first valve is closed, and water is injected into the inner bag only through the second valve; and S7, meanwhile, the water pumping end of a water pump is connected to the second pipeline of the outer bag, water is pumped through the first pipeline of the outer bag, and the inner bag is expanded and attached to the interior of the outer bag.
本申请涉及地连墙接头技术领域，具体是地连墙接头水囊封堵的施工方法，包括以下步骤：S1、将一对工字钢分别放入到成槽的两侧，在工字钢之间放置钢筋笼，确保其位置和稳固性；S2、将填充水囊放入工字钢远离钢筋笼的槽口中；S3、将Y型管道的一端连接到水泵的出水口，另外两个端口分别通过第一阀门和第二阀门连接到外囊和内囊的第一管道和第二管道上；S4、打开水泵，开始对外囊和内囊进行注水；S5、观察水压检测仪的读数，确保水压在正常范围内；S6、如果发现水压突然降低，则外囊出现破损。此时，关闭第一阀门，仅通过第二阀门向内囊注水；S7、同时，将水泵的抽水端连接到外囊的第二管道上，通过外囊的第一管道抽水，使内囊膨胀并贴合外囊内部。
