Description

TECHNICAL FIELD

[0002] Urban rain and sewage pipe networks are important components of urban infrastructure, and bear the key functions of rainwater discharge and sewage collection. The operation state thereof is directly related to the efficiency of the urban drainage system, environmental protection and the quality of life of residents. Due to the long-term underground burial of the pipe network, the pipe network is affected by factors such as soil pressure, chemical corrosion, mechanical wear and external construction, and is prone to defects such as cracking, clogging, leakage and deformation. If these defects are not promptly investigated and repaired, serious consequences such as sewage overflow, groundwater pollution and road collapse may occur.

[0003] In the prior art, the defect investigation of the urban rain and sewage pipe network usually uses a closed-circuit television (CCTV) detection method. Specifically, a staff member on site uses a detection vehicle carrying a camera to enter the pipe network, and real-time images of the inner wall are transmitted to the ground.
