وصف الحالة
The pipe wall is equipped with single-layer or multi-layer reinforced concrete circular pipe.
Concrete and reinforced concrete drainage pipe products are still widely used in municipal highway construction, farmland water conservancy construction, electric power and railway engineering construction and urban comprehensive pipe corridor construction at home and abroad due to their good external pressure resistance, durability, low production cost, convenient production, low price and long service life, etc, It plays a huge role in national infrastructure construction. With the development of national infrastructure, China's reinforced concrete drainage pipe industry has experienced a continuous development process from small to large, from less to more, from backward to advanced.
Concrete and reinforced concrete pipes have the unique advantages of high external compression strength, good durability, long service life, easy manufacturing, low production cost, and low price. They are widely used in the construction of cities and towns, industrial and mining enterprises, and farmland water conservancy construction in my country. Drainage pipes have achieved good economic and social benefits.
