Eccentric water stop principle

The principle of eccentric water stop is to replace the traditional hanging mould technology with water stop. When the structural floor is constructed, the water-stop joint is directly installed on the floor formwork, and the pipe body of the water-stop joint is poured into the structural floor concrete at one time. The water-stop joint has its own water-stop wing ring, which is closely bonded with concrete after pouring with the cast-in-place slab, which can effectively solve the problem of easy leakage caused by the need to reserve holes for the installation of riser passing through the floor. According to the relevant public information, the eccentric waterstop meets the design code of building drainage, which solves the problem that the installation riser of waterstop is not vertical and the installation is inconvenient. The contents of building drainage design include the classification and composition of drainage system, the hydraulic calculation method and steps of drainage system, the selection of drainage pipes and the principles of pipeline layout and laying.
