Reinforced concrete anti-corrosion drainage pipe joints are made of sepiolite mineral fiber, vinylon, and cement as the main raw materials. After being mixed and mixed with a high multiple, they are continuously rolled under pressure by a pipe making machine. It is widely used for cable maintenance of power system and communication system, and can also be used as water pipeline.

What's your opinion on a series of characteristics of concrete drainage pipes?

Concrete pipe professionals share with you the following:

In recent years, social development and continuous research and development of core technologies have led to continuous improvements in the environment. (Reinforced concrete drainage pipe) is an important part of municipal highway drainage engineering. Although you may not see it, it has been silently completing its mission to serve human beings, so what interfaces do such important cement pipes have? How about it?

At present, the interface forms of reinforced concrete drainage pipes are: flat mouth, rigid groove, socket and flexible groove. An example: Flexible enterprise interface interface form! The flexible tongue and groove uses a rubber ring to seal the water stop for its interface. It is a flexible connection with good seismic performance, can effectively resist uneven settlement of the foundation, and is fast and popular among users.

Primarily suitable for cement drainage pipes with a caliber ≥d1200. This interface form is also a flexible connection. This interface form has the advantages of the socket type, and it is more obvious than the socket type, but it also has an obvious feature that the socket type does not have.

It is suitable for large-diameter pipes, the depth of the joint pit of the socket pipe device is not easy to control, it is not easy to compact when backfilling, the stress at the transition of the pipe socket is concentrated, and the pipe body will show circumferential cracks in severe conditions, which affects the service life of the pipe, and the flexible tongue and groove The body of the pipe is in good contact with the root bed, and it is evenly beared when subjected to load forces, so it is safer to use; the outer wall of the socket of the socket pipe is a sloped surface, so it is difficult to control and easily leak when the inspection well is built. The flexible enterprise management can be improved a lot; the flexible enterprise management can also be used as a pipe jack.

Reinforced concrete anti-corrosion drainage pipe joints are made of sepiolite mineral fiber, vinylon, and cement as the main raw materials. After being mixed and mixed with a high multiple, they are continuously rolled under pressure by a pipe making machine. It is widely used for cable maintenance of power system and communication system, and can also be used as water pipeline.

characteristic:

1. Low price, simple structure and convenient construction.

2, good processing performance, the device allows corners.

3. The current carrying capacity is high, and the laying coefficient is 10% higher than that of PVC pipes.

4, stable chemical properties, no aging, and its strength increases at any time.

5. Corrosion resistance and non-magnetization.

6. The inner wall is lubricated, and the roughness coefficient is 0.07.

Application scope of reinforced concrete drainage pipe joints: Class A pipes are suitable for concrete encapsulation and laying. The B-type pipe is suitable for the direct buried laying of non-motorized lanes such as sidewalks and green belts. It is also suitable for the concrete enveloped laying of motorized lanes where heavy-duty vehicles pass.
