The drainage pipe was originally intended to be used for drainage, including drainage of rainwater and sewage. In practice, the drainage pipe has a wide range of applications and has exceeded its original definition. Concrete drainage pipes are currently commonly used in the following areas:
(1) Rainwater pipe: It is used to collect and discharge rainwater, surface soaked water, etc., and the maximum amount is used. Ordinary pipes with an inner diameter of 250 to 1200mm are mostly socket-type flexible joint pipes, and those with an inner diameter of 1350mm or more are mostly flexible tongue-and-groove pipes. Because rainwater pipes are usually buried shallowly, most of them adopt the construction method of grooving and embedding; in some burial depths or the excavation cannot be excavated due to site conditions, the jacking method is used instead, and the corresponding pipes need to be modified. Use flexible steel socket tube.
(II) Sewage pipe: It is used to collect and discharge liquids that cannot be directly discharged into rivers, such as domestic sewage and industrial sewage. In recent years, with the country's efforts to improve the environment, the use of this pipe is also very large. Coming bigger. The construction method of the sewage pipe is similar to the construction method of the drainage pipe. It is used for slot buried or jacked construction, and the joint method is the same.
(3) Auxiliary casing: Concrete pipes for maintenance of special pipelines, such as cables, communication cables, gas pipelines, etc., which are mainly used for construction convenience, and can also reach installation and maintenance requests. Concrete drainage pipes are used. Characteristics, first install a large-diameter concrete drainage pipe at the location of the design pipeline, and then set up the utility pipeline in the pipeline.
(4) Other pipes: For example: water application pipes and so on.
