Therefore, the conventional construction method has the following disadvantages in actual construction:
(1) the embedded rubber water stop is fixed only by utilizing the clamping force of the template, the embedded part does not take a fixing measure, and when the cast-in-place concrete is constructed, the part of the embedded rubber water stop embedded in the concrete deviates to one side due to the flowing extrusion force of the concrete, so that one side of the part of the embedded rubber water stop embedded in the concrete is thick while the other side is thin, and the leakage is easy to cause.
(2) When the buried rubber water stop belt is buried in concrete and no fixing measure is taken, the steel edge of the buried rubber water stop belt is deformed in the construction process, the buried rubber water stop belt is curled under the impact of the discharged concrete in the cast-in-place concrete pouring process, a leakage point is easily formed at the position, and the waterproof effect is seriously influenced.
