Abstract
Description
Technical Field
[0001] The utility model relates to the field of plastic pipes, in particular to a reinforced water stop joint for a plastic pipe. Background Art
[0002] The reinforced water stop of plastic pipe is one of the key technologies to solve the problem of water leakage at the root of pipes in construction projects. At present, many companies pre-buried water stop at the root of pipes in order to solve this technical problem. The main advantage of the water stop is that it is pre-buried once, and no holes are left to fill holes, which solves the quality problem of water leakage around the hanging hole of traditional drainage pipes. In addition, it has a large displacement adjustment distance and is easy to construct. There will be no phenomenon that the pipe cannot be installed due to the position deviation of the upper and lower layers. The use of water stop can reduce the later links such as hanging molds, thereby saving a lot of processes and greatly improving construction efficiency. Due to the small size and light weight of the water stop, we usually put it in the whole box for transportation. During the transportation process, the water stop is collided with each other. Due to the material problem, the water stop is very likely to be damaged by the collision. In order to avoid the loss caused by this transportation, we proposed the reinforced water stop of plastic pipe. Utility Model Content
