Waterproof casing flexible waterproof casing s312 waterproof casing casing

The role of the rubber ring inside the flexible waterproof casing. During construction, expansion joints must be left between the flexible waterproof casing and the pipe joints. Otherwise, the flexible waterproof casing will not be able to play a flexible role. On the contrary, the chance of water leakage will increase due to the loose opening of the rubber ring. For drainage horizontal pipes or local pressure-bearing pipes at the bottom of the building, high-quality drainage cast iron pipes or water supply cast iron pipes (various types of waterproof casings) can be used to meet the pressure-bearing requirements. The excess adhesive on the outer skin of the plastic pipe must be wiped clean. When lifting the mold, it is best to wrap the installed pipe below with plastic film or waste paper. This can not only reduce the cleaning work after the completion of the project, but also maintain the original pipe. of smoothness. For some construction parts with higher requirements, it is best to use a water-stop ring, stick the water-stop ring on the riser, and drive it into the concrete together to increase the crawling distance of the joint surface and leaking water, so that the waterproof casing can play a greater role. Good watertight effect.
Flexible waterproof casings should be equipped with rubber water-stop rings, which play a greater role. Rigid waterproof casings can be used for drainage pipes in boiler rooms and steam washing machine rooms, which not only solves the problem of high temperature resistance but also overcomes the problem of flexible waterproofing. The disadvantage of casing is poor heat resistance. There are many problems with drainage pipes in projects. Here, we will briefly analyze the problems that arise with flexible waterproof casings during drainage pipe construction. The drainage pipe construction specifications do not require that the outer wall of the pipe where the pipe passes through the flexible waterproof casing should be roughened to make it more closely bonded with the concrete to achieve waterproofing purposes. Rubber water-stop rings and flexible waterproof casings can also be added. During the construction process, casing hangers should be installed in time according to specifications to prevent pipeline breakage.
