Interface method of concrete drainage pipe and habitual planning
Cement pipe
At present, the interface methods of reinforced concrete drainage pipes are: flat mouth, rigid groove, socket and flexible groove. Due to the low construction power and poor seismic performance of the flat mouth pipe and the rigid riser pipe, the displacement of the foundation will swing the joint away and cause damage to the road surface. Therefore, these two interfaces have not been selected at all in the project. The socket and the flexible tongue and groove are made of rubber ring to seal the water stop because of the interface. It is a flexible connection with good seismic performance. It can be used to resist uneven settlement of the foundation, and the equipment is fast and popular among users.
The basic structure is that two rigid end plates are fixed to the two ends of the drainage pipe through a pull rod. In order to ensure the tightness under regular water pressure, the tube end and the rigid end plate touching part are filled with elastic data. After the end plate of the test equipment is sealed with the drain pipe, it is filled with water inward and pressurized to the required inspection pressure, so as to query the closed seepage condition.
Reinforced concrete drainage pipe joints are suitable for planning: Class A pipes are suitable for concrete encapsulation and laying. The B-type pipe is suitable for the direct laying of non-motorized lanes such as sidewalks and green belts, as well as the concrete encapsulation and laying of motorway with heavy-duty vehicles passing by.
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 high multiples of water, they are continuously rolled by the pipe making machine under pressure. It is widely used for cable protection in power systems and communication systems, and can also be used as a water pipeline. characteristic:
1. Low price, simple structure and convenient construction.
2. The processing function is good, and the equipment allows corners.
3. High ampacity, laying factor is 10% higher than PVC pipe.
4. The chemical function is stable, not aging, and its strength is increased at any time.
5. Corrosion resistance and non-magnetization.
6. The inner wall is lubricated, and the roughness coefficient is 0.07.

Features of joints for cement pipes
Cement pipe
The interface methods of cement pipes are: flat mouth, rigid groove, socket and flexible groove. Let us introduce the joint characteristics of cement pipes.
1. Low price, simple structure and convenient construction.
2. The processing function is good, and the equipment allows corners.
3. High ampacity, laying factor is 10% higher than PVC pipe.
4. The chemical function is stable, not aging, and its strength is increased at any time.
5. Corrosion resistance and non-magnetization.
6, inner wall lubrication, roughness coefficient is 0.07.


Introduction to the characteristics of concrete manhole covers
Concrete manhole covers have the following characteristics:
1, can be made according to different customers: municipal, postal, telecommunications, electricity and other special logos, can also be the name of the manufacturer of the production company and the telephone.
2. Beautiful and generous: The injection mold is selected, and the product cover is lubricated and light.
3. The compressive strength is high, the heavy-duty cover can pass the trailer of 80 tons, and the joint is flat, and the vehicle is rolled without damage, slip, rollover, and noise.
4. It is convenient to manufacture. It only needs to load the equipped steel fiber and concrete into a plastic mold and oscillate. The demolding cycle is short, the investment is small, and the labor intensity is low.
5. The manufacturing cost is low, and the original materials are easy to buy.
