Design and Application of Pressure Jacking Pipe of Centrifugal Casting Glass Fiber Reinforced Plastic Pipe
Taking the pressure pipe jacking project of a trunk sewage pipe project in Ningbo as an example,the relevant calculation of pressure pipe jacking of centrifugal casting glass fiber reinforced plastic pipes is systematically expounded from the aspects of process design and structural design.The glass fiber reinforced plastic jacking pipe is a kind of chemical composite pipe with the strong designability of mechanical properties.The main parameters of the pipe such as the nominal pressure,allowable jacking force and ring stiffness determined in the process design should be further confirmed with the main pipeline manufacturers in the market.The most unfavorable section of the pipeline should be checked for strength,deformation,anti-seismic and other structural design to ensure the safety and reliability of the pipeline structure,which can provide reference for the application of other pressure jacking pipe projects of centrifugal casting glass-fiber reinforced plastic pipes.
