Reinforced concrete drainage pipes from our drainage pipe manufacturer are widely used in public facility drainage systems, serving as a lining material embedded and fixed to the inner wall of the pipes. These reinforced concrete drainage pipes are manufactured through various processes including centrifugal casting, radial extrusion, and vertical core mold vibration, which enhance their hardness and ensure their ability to withstand external pressure. Advantages of reinforced concrete drainage pipes:

Reinforced concrete drainage pipes are not only used in drainage systems but also applied in various fields such as agricultural irrigation, chemical industry, gas, and mining. The widespread use of reinforced concrete drainage pipes is attributed to their inherent advantages. ① They offer excellent quality at low manufacturing costs; ② Their production process is relatively simple and quick, enabling rapid fulfillment of customer demands; ③ They possess high hardness, capable of withstanding strong water pressure; ④ The structure is rational, allowing for good assembly and connection, ensuring overall tightness and preventing leaks; ⑤ The inner surface is extremely smooth, ensuring the system's unobstructed flow, thereby reducing the likelihood of sediment accumulation and blockages; ⑥ They are highly durable and made from stable and earthquake-resistant materials.

Production Requirements for Reinforced Concrete Drainage Pipes:

High-quality reinforced concrete drainage pipes from a drainage pipe manufacturer ensure the service life of the pipes. The overall structure is uniform with no delamination, allowing for a more efficient drainage system.

2. In terms of the strength of reinforced concrete drainage pipes, the strength grade of reinforced concrete drainage pipes using conventional excavation methods should not be lower than C50, while the strength grade of those using jacking construction methods should not be lower than C55. The strength of the reinforced concrete drainage pipes upon delivery should not be less than 90% of the designed strength.

3. The interior lining of reinforced concrete drainage pipes is composed of PVC composite drainage pipe materials, which consist of the pipe body and the lining layer. Manufacturers of drainage pipes require the outer surface to be smooth and intact, free from issues such as adhesion loss, roughness, honeycomb structures, hollowed areas, or collapses. Similarly, the inner surface should also be relatively smooth, without any damage or drilling. Additionally, the overall pipe material should not exhibit cracks, while surface crazing and drying shrinkage cracks in the mortar layer can be overlooked. In terms of impermeability, the waterproofing grade of reinforced concrete drainage pipes should not be lower than S6.

In summary, the current reinforced concrete drainage pipe manufacturing process is the vertical core mold vibration pipe-making technique. This method not only boasts high automation and overall production efficiency, but also results in high-strength reinforced concrete drainage pipes with excellent anti-seepage properties and high load-bearing capacity during construction. Additionally, the density of the compacted concrete can be adjusted by varying the vibration frequency.
