[0002] As an excellent performance water supply and drainage pipe, the prestressed concrete cylinder pipe has extremely important applications in the urban water supply and drainage pipe networks. Whether the prestressed concrete cylinder pipe is used to lay the water supply pipe network or the sewage pipe network, it is buried underground. Since there are many harmful media in the soil and the outer wall surface of the prestressed concrete cylinder pipe is a cement surface, if it directly contacts the soil, the outer wall of the prestressed concrete cylinder pipe is very easy to be corroded. Therefore, it is necessary to perform anti-corrosion treatment on the outer wall of the prestressed concrete cylinder pipe.
[0003] When spraying the inner wall of the existing prestressed concrete cylinder pipe, most of them are manually spraying with a spray gun against the inner wall of the pipe. This method not only has high requirements for the operation skills of workers, but also is extremely easy to have uneven coating, thus reducing the anti-corrosion performance of the prestressed concrete cylinder pipe. For this reason, we propose an anti-corrosion spraying device for a prestressed concrete cylinder pipe. Content of the Utility Model
