How is urban sewage discharged through cement pipes
Generally, large-diameter pipe installations are selected for urban drainage pipes. In addition to large-diameter sewage discharge pipes, pressure resistance is required, because sewage pipes exist under urban roads, and the pipes will accept the pressure of different vehicles every day, and in sewage There will also be a lot of impurities, so the inner wall of the sewage discharge pipe needs to be lubricated and can accept pressure. The cement pipe is the most commonly used sewage pipe, because the displacement of the cement pipe is large, and the production cost of the cement pipe is low. The production is fast, and the number of sewer pipes required by the city is large. Therefore, the lower water pipes need to choose good quality and cheap pipes.
The shape of the cement pipe is larger and smaller, so the connection of the time-division cement pipe of the device will be more tight, the drainage quality is better, and the possibility of water leakage halfway is small. The inside of the cement pipe and the pipe head are relatively lubricating, so impurities in the water during the drainage are not easy to remain in the pipe, so the patency of the pipe will be better.
