Power tunnel plays an increasingly important role in the power system, which is the source of power for urban operation and development, but the problem of tunnel leakage is becoming more and more prominent, which directly affects the normal inspection and maintenance of power cables. In order to better solve this problem, through the analysis of the current situation of power tunnel leakage, using scientific construction technology and the application of new polymer waterproof materials, the problem has been better solved.
