  • Method and system for automatically monitoring and identifying water seepage of segment joint of subway shield tunnel
    Patent number: 12596046
    Abstract: The present disclosure provides a method and system for automatically monitoring and identifying water seepage of a segment joint of a subway shield tunnel. The method includes: 1): grinding a water-sensitive material and then mixing with a waterproof material to form a color-developing agent; 2): coating the color-developing agent on two sides extending from a construction joint and/or a deformation joint of a tunnel lining as a center line, to form a color-developing layer; and 3) obtaining a color development feature of the color-developing layer, and identifying water seepage based on the color development feature. According to the present disclosure, a water seepage amount can be determined based on the color development feature of the color-developing layer around the construction joint and/or the deformation joint of the tunnel lining, which facilitates monitoring of the water seepage amount around the construction joint and/or the deformation joint.
