[0002] In the safety management of reservoir projects, seepage monitoring, as an important part of dam safety monitoring, is an important basis for evaluating the operating status of dams and other hydraulic structures. Dam seepage will damage the anti-seepage and drainage equipment rooms, cause seepage damage to the dam foundation and structure, and reduce the stability of the dam slope.

[0003] There are various existing methods for dam seepage detection, including opening a rectangular water collection tank on the dam wall to understand the seepage status of the dam by observing the seepage speed in the water collection tank. However, the existing water collection tank can only understand the seepage speed of the dam, and it is difficult to judge the seepage speed at different heights on the dam, which is not convenient for evaluating the safety effect of the dam.

[0006] Preferably, an outer wall at one end of the seepage monitoring box includes a drainage pipe, a top end of the drainage pipe is located at the top of the dam body, and a bottom end of the drainage pipe is located downstream of the dam body.

[0007] Preferably, an outer wall of one side of the drain pipe is equipped with equidistantly distributed liquid guiding tubes through an opening, and a bottom end of the flow meter is connected to a liquid guiding hose, and a pipe joint is fixedly provided at the end of the liquid guiding hose, and the inner wall of the pipe joint is fixedly connected to the outer wall of one end of the liquid guiding tube. The water in the seepage monitoring box flows into the flow meter through the drainage elbow, and the water in the flow meter is input into the drain pipe through the liquid guiding hose and the liquid guiding tube, and the water is discharged into the downstream of the dam through the drain pipe.

[0008] Preferably, a support sleeve is fixedly provided on the bottom inner wall adjacent to the seepage monitoring box, and a positioning hole is opened on the top outer wall of the support sleeve.

[0009] Preferably, a vertical downward support rod is fixed on the bottom outer wall of the adjacent seepage monitoring box, and the outer wall of the support rod is provided with limit holes distributed at equal distances. The outer wall of the support rod is slidably connected to the inner wall of the support sleeve, and the inner walls of the positioning hole and the limiting hole are provided with matching bolts. By adjusting the depth of the support rod inserted into the inner wall of the support sleeve, and then using the bolts to insert into the inner walls of the positioning hole and the limiting hole, the distance between the adjacent seepage monitoring boxes can be conveniently controlled.

[0010] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0011] The seepage monitoring boxes arranged vertically and equidistantly are installed in a rectangular water storage trough on the dam body.
