The communication cables detection using radar in the sewers construction

Urban sewage pipeline project often using the pipe jacking technology, the existing communications cables had an obstacle in the construction process, affecting the progress of the project. This paper introduced the principle of the radar method to detect underground pipeline. Combined with project examples, it described the application of determining the location of the original communication cable before the pipe jacking process begins, it had a positive guidance to the right to solve the problem of similar projects.
