Description
Technical Field
The utility model belongs to the technical field of the concrete pipe technique and specifically relates to a reinforced concrete pipe.
Background
Concrete pipes are made of concrete or reinforced concrete and are formed by centrifugal, vibratory, roller, vacuum processes and combinations of roller, centrifugal and vibratory processes. Prestressed concrete pressure pipes are being developed more in china and many other countries in order to improve the service properties of concrete pipes. The pipe is provided with longitudinal and circumferential prestressed reinforcements, so that the pipe has high crack resistance and impermeability. In the 80 s, China and other countries developed self-stressed reinforced concrete pipes, which were mainly characterized by the fact that the expansion of self-stressed cement (special cement) during the hardening process was used to generate prestress, simplifying the manufacturing process. Compared with steel pipes, the concrete pipe can save a large amount of steel, prolongs the service life, has less factory building investment and convenient laying and installation, and is very commonly used in factories, mines, oil fields, ports, urban construction and farmland hydraulic engineering; the reinforced concrete pipe is widely applied due to simple structure and low price, and the enterprise finds that the reinforced concrete pipe at the present stage has some problems after field investigation and use investigation of old customers;
