　　Cast iron drainage pipe manufacturer directly supplies urban sewage drainage pipes

　　What is the main purpose of cast iron drain pipes in engineering?

　　Cast iron drainage pipes are widely used in drainage areas such as highways, railway subgrades, subway projects, landfills, tunnels, green belts, sports fields, and slopes caused by high water content, as well as circular drainage pipes for agricultural and horticultural underground irrigation and drainage systems. They are a structurally complete cast iron drainage pipe suitable for paving structures with waterproof layers for longitudinal drainage. The inner diameter of the drain pipe is generally 0.10? 0.15m， The lower end of the drain pipe should be extended. At least 0.15 below the bottom of the lane board? At 0.20m, to prevent water seepage and wetting of the surface of the main beam ribs.

　　Mainly used for railway bridge drainage, bridge guardrail supports on both sides of highways, engineering and chemical wastewater treatment systems. Underground drainage for site preparation projects; For overpasses and bridges on highways, it is not allowed to directly hang drainage pipes under flat plates. The drainage pipe can be directly led to the ground through longitudinal and vertical drainage pipes, or it can be implemented according to design requirements. The drainage pipe should use fixed devices such as anchoring tracks and clamp inserts.

　　It has the advantages of high impact strength, high mechanical performance, good toughness, and strong resistance to flexibility, thereby reducing the problem of crushing during construction and use. Especially suitable for drainage pipes in airports, highways, and railways. Vertical and horizontal drainage on the back of various retaining walls and highway side ditches; Soil and water conservation for slope development;

　　The construction of cast iron drain pipes should be carried out in accordance with design requirements, and the drain pipes should extend beyond the bottom of the structure. Less than 30mm and with a longitudinal spacing of no more than 4m. The construction of drainage pipes should be carried out according to design requirements. The drainage pipe should extend from the bottom of the building by no less than 30mm, with a longitudinal spacing of no more than 4m. It has a beautiful and elegant appearance, smooth inner walls, low friction coefficient, corrosion-resistant and wear-resistant inner walls, no scaling, reduces fluid friction resistance, improves fluid transport efficiency, and reduces noise.
