What is the production process of reinforced concrete drainage pipe?
What is the production process of reinforced concrete drainage pipe? Reinforced concrete drainage pipes use advanced production technology and equipment. After years of practice in pipe making processes such as centrifugation, suspension rolls, vertical vibration, and radial extrusion, through more than two years of inspection of various pipe making processes at home and abroad Investigation, through expert guidance and insight into the future development trend of the pipeline, Zhongjunda Pipe Industry chose the vertical core mold vibration pipe manufacturing process. This process is now an internationally advanced concrete pipe-making process.
At present, the connection methods of reinforced concrete drainage pipes are: flat mouth, rigid groove, socket and flexible groove. Due to the low construction power of flat-end pipes and rigid riser pipes (concrete base, joint wiping tape), the seismic performance is poor, and the displacement of the foundation will cause the joints to open and cause road surface subsidence and damage. Therefore, these two interfaces are basically not used in engineering. The socket and the flexible tongue and groove are flexible joints due to the use of rubber rings to seal the interface, which is a flexible connection, has good seismic performance, can effectively resist uneven settlement of the foundation, and is popular among users for its fast installation speed.
