Remote System Design of Urban Underground Comprehensive Pipe Gallery Inspection

With the advancement of urbanization, various underground pipelines such as natural gas pipelines, communication pipelines, water lines, and other lines gradually become the lifeline to maintain the normal operation of the city. Thus, the daily inspection and maintenance of pipelines are needed to prevent problems such as water pipeline leakage. The urban underground integrated pipeline corridor is buried deep underground so manual inspection faces the risk of gas leakage and corridor fire. The corridor length of dozens or even hundreds of kilometers, resulting in high costs of manual inspection. Thus, pipeline repair scenarios are required as pipelines are buried deep underground, and the excavation causes environmental pollution and traffic congestion. Underground pipelines have a high cost of maintenance and inspection. Integrated pipeline corridors in the urban underground can be used to solve these problems. The integrated pipeline corridor is managed in a centralized underground space. In the middle of the corridor for manual and robotic inspection channels, to solve these problems, we designed a set of an unmanned urban underground integrated pipeline corridor inspection system with an overall system design.
