The interface forms of cement pipes of reinforced concrete drainage pipe manufacturers include: flat end, rigid groove, socket and flexible groove. Due to the low construction efficiency and poor seismic performance of plain and rigid tongued and grooved pipes, the displacement of the foundation will pull the interface apart, leading to the collapse and damage of the pavement. Therefore, these two interfaces are basically not used in the project. Socket and flexible tongue and groove are popular with users because of their flexible connection, good seismic performance, effective resistance to uneven settlement of foundation, and fast installation speed.
The basic structure is to fix two rigid end plates on both ends of the drainage pipe through pull rods. In order to ensure the tightness under the specified water pressure, the contact part between the pipe end and the rigid end plate is filled with elastic material. After the end plate of the test device is sealed with the drain pipe, inject water inward and pressurize it to the required inspection pressure, so as to observe the closed water seepage.
Reinforced concrete drainage pipe manufacturer
Scope of application of reinforced concrete drainage pipe joint: Class A pipe is suitable for concrete encasement laying. Class B pipes are applicable to the direct burial laying of non-motor vehicle lanes such as sidewalks and green belts, and also to the concrete encapsulation laying of motor vehicle lanes with heavy vehicles passing through.
Reinforced concrete anti-corrosion drainage pipe joint is a non-metallic pipe made of sepiolite mineral fiber, vinylon and cement as the main raw materials, fully mixed and mixed with high expansion water, and continuously rolled by the pipe making machine under pressure. It is widely used for cable protection of power system, communication system, and water transmission pipeline. characteristic:
1. Low price, simple structure and convenient construction.
2. Good processing performance, installation allows corner.
3. The carrying capacity is high, and the laying coefficient is 10 percentage points higher than that of PVC pipes.
4. The chemical properties are stable, non-aging, and its strength increases with time.
5. Corrosion resistance and non-magnetization.
6. The inner wall is smooth and the roughness coefficient is 0.07.
