[0002] In recent years, large-scale urbanization construction has effectively promoted the development of urban municipal infrastructure construction. The underground drainage pipe network with reinforced concrete pipes as the main structural members is an important part of the urban municipal infrastructure, effectively ensuring the collection and transportation of urban domestic sewage, industrial sewage and floodwater. As is known to all, leakage often occurs in drainage pipes, which not only affects production and people's daily life, but also causes water resource waste and even serious accidents such as foundation collapse.

[0003] Although there are strict regulations on the acceptance of drainage pipes in China, there is no specific requirement for the detection of the internal pressure of the drainage pipes. The current detection of drainage pipes mainly observes the leakage phenomenon of the drainage pipes by injecting water with a certain pressure into the closed drainage pipes within a given time, but for concrete and reinforced concrete drainage pipes, the length and weight of the pipes directly restrict the detection device, and the detection device is difficult to adapt to different concrete and reinforced concrete drainage pipes, which seriously affects the detection of the internal pressure. During the pipe joint assembly and jacking construction process, it is a problem and challenge for the project to ensure the butt joint quality of the ultra-large-diameter reinforced concrete pipe joint and reduce the leakage phenomenon.
