With the rapid development of urban construction, the role of cement drainage pipes in urban construction is becoming larger and larger. It can be used not only for drainage and sewage, but also for drainage and flood relief. With the widespread use of cement drainage pipes, In terms of its construction, we should pay attention to it to avoid unnecessary troubles in the later application process. The following is a small series of cement pipe manufacturers' construction process for us on the cement drainage pipe.
In the case where the cement drainage pipe is so widely used, we must have a certain understanding of its construction technology during the construction process. If there is a big problem in the later use due to a small problem during construction, it is worth the loss.
1. Open cut method, also called slot construction method. Dig trenches according to the measurement alignment during construction. Generally, small and medium diameter drainage pipes are made of reinforced concrete pipes, large and medium diameter.
2. Pipe jacking method. Excavation operation pits in the direction of the inspection well. The pits and steel plates facing the stub section form a solid back, and the pit walls on other sides are used as general support. For more pipe jacking pits, continuous wall or sinkhole method can be used for construction.
3. Shield method. A shield is a large working tube with an excavator and a jacking device. The lined pipe section is pushed forward as the back seat, and the space left after the pushing is used to line the wall surface, forming the pipe body. At present, large-scale drainage pipes in China have been constructed by shield tunneling.
