The invention discloses a long-term real-time monitoring device and method for leaking water at the joint of a tunnel, comprising a conductivity measurement unit, a data acquisition unit, a wireless transmission network and a data processing system, the conductivity measurement unit includes a plurality of resistance sheets, the The resistive sheet is pasted at the joint of the tunnel, the resistivity at the joint is measured, and the resistivity is sent to the data acquisition unit through the transmission line. The data acquisition unit summarizes the information of each resistive sheet and transmits it through the wireless transmission network. The data is sent to the data processing system for storage. The data processing system eliminates invalid data, extracts abnormal data caused by water leakage, and determines the corresponding seam position according to the obtained abnormal volume data. The invention can make up for the deficiency that the current commonly used detection method cannot realize long-term real-time monitoring of tunnel water leakage.
Description
technical field [0001] The invention relates to a device and method for long-term real-time monitoring of leakage water at tunnel joints. Background technique [0002] With the rapid development of subway tunnels in my country, there are still many problems to be solved urgently, such as tunnel water leakage, which has become one of the most common problems in tunnel engineering in my country. Water leakage will seriously affect the stability of tunnel structures, resulting in Engineering disasters such as tunnel uneven settlement and tunnel deformation endanger the safety of people's lives and properties. It can be seen that the long-term real-time monitoring of tunnel water leakage and timely understanding of the leakage situation are particularly important. [0003] According to statistics, water leakage in the circular joints and longitudinal joints in the tunnel exceeds 93% of the total water leakage in the tunnel. Therefore, if no water leakage occurs at the joints, th...
