1, pipes and floor drains pass through the floor slab without reserved holes or improperly reserved. In actual construction, the reserved materials often shift, or according to the situation that there is no reserved pipe hole. The remedy must be to use a sledgehammer to drill a hole in the cast floor, or to empty the original hole after displacement, and to enlarge the hole when digging alone, and so on. The floor is prone to cracks, leaving artificial leakage problems.
2. Pipe hole plugging is not implemented as required, and the quality of pipe hole filling construction is poor. At the same time, the sealing material is unqualified, and some use plain concrete that does not meet the mixture ratio to seal the pipe hole, which makes the hole sealing loose and not dense; There are even bricks, gravel and other sundries in the pipe hole, and the surface is smooth and smooth with cement mortar, which actually leaves a serious leakage hazard.
3. There is no blockage between the pipeline and the casing. The casing is not higher than the ground, and water drips down the gap between the pipes.
Second, the responsibility and repair:
The maintenance fund is to repair the damage of the public part, and the damage in the real estate is repaired by the owner. Because the floor drain exists to realize the function of the house at home, it should be repaired by itself.
