Abstract
The invention relates to a construction method of a water bag type concrete engineering deformation joint water stopping cavity die with protrusions. The cavity die comprises a framework and a water bag. The water bag is connected with the framework and arranged on the outer side of the framework. When the cavity die is applied, the framework is connected with a water stop strip which is embedded in the cross section of first-stage concrete. The water bag is filled with water. Second-stage concrete is poured. After the second-stage concrete is initially set, water in the water bag is released, after the framework and the water bag are removed, a semicircular cavity capable of being filled with molten asphalt is formed in the cross section of the second-stage concrete, and the water stopping effect can be achieved by injecting the molten asphalt into the cavity. The deformation joint seepage problem caused by differential settlement or diastrophism of stratums in hydraulic engineering can be solved, and the cavity die can be utilized repeatedly.
