What are the corrosion protection and pipe effects of concrete pipes?

The nozzle methods of concrete pipes used for drainage are usually flat mouth pipe, groove pipe and socket pipe. Depending on the shape of the nozzle, the method of connection is different. Pipe interfaces are generally divided into three types: flexible interfaces, rigid interfaces, and semi-flexible interfaces. Flexible or semi-flexible joints should be used for sewage pipes with higher interface requirements and tighter water tightness.

What are the corrosion protection and pipe effects of concrete pipes?

The concrete pipe professional explained with us the following analysis:

1. Selection of drainage system

The drainage project design should be based on the approved overall planning of the local township (region) and the overall planning of the drainage project. The selection of the drainage system (diversion system or combined system) should be based on comprehensive consideration and confirmation based on township and industrial enterprise planning, local rainfall conditions and discharge standards, original drainage facilities, sewage treatment and utilization conditions, terrain and water bodies. The drainage system of the newly built area is selected by the shunt system.

2.Pipe selection

Generally, metal pipes are rarely used for outdoor pressureless drainage pipes. Metal pipes are only used when the drainage pipe needs to accept higher pressure or has strict leakage requirements (such as the inlet and outlet pipes of sewage pumping stations). More common are concrete and reinforced concrete pipes.

3.Selection of reinforced concrete pipe interface

The nozzle methods of concrete pipes used for drainage are usually flat mouth pipe, groove pipe and socket pipe. Depending on the shape of the nozzle, the method of connection is different. Pipe interfaces are generally divided into three types: flexible interfaces, rigid interfaces, and semi-flexible interfaces. Flexible or semi-flexible joints should be used for sewage pipes with higher interface requirements and tighter water tightness.

4. Pipeline elevation control

Pipeline elevation control should be comprehensively considered from multiple aspects: in order to ensure the drainage of rainwater and sewage in the area served by the pipeline, the pipeline must have a sufficient burial depth; as the burial depth increases, the trenching depth increases, and the construction difficulty also follows. Increase, especially in weaker soil, it will inevitably increase the cost of the pipeline network; at the same time, the municipal pipelines under urban roads are confusing. In order to make the pipelines basically staggered from each other, the elevations of the pipelines should be reasonably controlled. In order, the order of pipelines from top to bottom is power pipe (ditch), telecommunication pipe (ditch), gas pipe, water pipe, heat pipe, rain pipe, sewage pipe.
