The invention discloses a tunnel water leakage detection method and device based on a temperature gradient. By arranging a temperature sensor array on the inner wall of the tunnel, the temperature difference between the water and the wall and the evaporation and heat dissipation of the water are utilized, and according to the temperature of each platinum resistance measuring point The temperature is used to judge whether there is leakage in the measured area, and the shape of the leakage area can be estimated according to the detection information. The invention can locate and alarm in time when water leakage occurs, so that management personnel can discover and control tunnel water leakage diseases at the first time. In addition, it can also monitor the development of existing water leakage diseases for a long time and help observe the tunnel Structural performance evolution trend.
Description
technical field [0001] The invention relates to the technical field of tunnel water leakage detection, in particular to a temperature gradient-based tunnel water leakage detection method and device. Background technique [0002] With the improvement of the modernization level of our country's cities and the acceleration of people's life rhythm, the subway is gradually becoming an important part of the public transportation system in big cities due to its convenient and fast advantages. A large number of provincial capital cities and some second-tier cities are investing huge sums of money to build new subways . At the same time, the problems facing the healthy service of subway tunnels have become increasingly prominent. Leakage is the most common and typical structural disease of subway tunnels. Many urban subways in my country are plagued by serious water leakage. [0003] Under the long-term erosion of groundwater, the concrete and steel bars in the tunnel lining are co...
