Old residential pipe network renovation, steel belt bellows replace original cement pipes

Due to the long-term service of the original cement drainage pipe network in the old community, there are widespread problems such as material aging, pipe wall cracking, joint leakage, etc., which not only has low drainage efficiency, but also easily causes hidden dangers such as waterlogging and road settlement, which becomes an obstacle to the improvement of the community environment. Replacing the original cement pipeline with steel bellows is an efficient solution to meet the needs of the transformation of the old community.

The steel belt corrugated pipe is based on plastic and embedded with high-strength steel strip. It has both the corrosion resistance of plastic and the structural strength of metal. It can withstand large soil pressure and external loads, and is suitable for the complex underground environment of the old community. Compared with cement pipes, its weight is only about 1/5 of the same specification of cement pipes. It does not require large-scale lifting equipment. It can be handled and laid in a narrow space of the community, which greatly reduces the construction difficulty and construction cost. At the same time, the pipes are connected by sealed sockets, which effectively avoids the problem of joint leakage and improves the sealing and stability of the drainage system.

During the construction process, it is necessary to combine the actual geological conditions of the community, do a good job of leveling and strengthening the pipeline foundation to ensure that the pipes are evenly stressed after laying; strictly follow the specifications to complete the interface sealing during installation to avoid hidden dangers of leakage in the later stage. After the renovation is completed, the large flow diameter of the steel belt corrugated pipe can significantly improve the drainage efficiency, and the corrosion resistance characteristics can greatly prolong the service life of the pipe network, reduce the frequency and cost of subsequent maintenance, and create a long-term and reliable drainage system for the old community to help upgrade the quality of the living environment.
