Abstract
The invention relates to a construction method for a concrete work deformation joint water stop cavity die with reinforced fibers. The cavity die comprises a framework and a water bag. The water bag is connected with the framework and is arranged on the outer side of the framework. When the cavity die is applied, the framework is connected with a water stop piece embedded at the position of the section of first-stage concrete. The water bag is filled with water. Second-stage concrete is poured, and after the second-stage concrete initially sets, the water in the water bag is released out. After the framework and the water bag are removed, a semicircular cavity allowing molten asphalt to be injected therein is formed in the section of the second-stage concrete, and the water stop function can be achieved after the molten asphalt is injected in the cavity. According to the construction method, the problem of deformation joint water seepage, caused by differential settlement or dislocation of a stratum, of the water conservancy project can be solved, and the die cavity can be repeatedly used.
