The pipe wall of circular concrete pipe is equipped with single or multi-layered framework of steel reinforcement.
Concrete and reinforced concrete sewer pipes are still widely used in domestic and foreign municipal highway construction, agricultural irrigation and water conservancy construction, power and railway engineering construction and urban integrated corridor construction, and play a key role in the infrastructure construction because of its irreplaceable advantages such as good external compression performance, durability, low production cost, convenient production, low price and long service life. With the development of national infrastructure construction, the reinforced concrete sewer pipe industry in China has experienced a continuous development process from small to large, from few to many, and from backward to advanced.
Concrete and reinforced concrete pipes have unique advantages of high external compressive strength, durability, long service life, easy manufacture, low production cost and low price, and has achieved good economic and social benefits in urban construction, industrial and mining enterprise construction, agriculture and water conservancy construction.
