Abstract

The invention discloses a device and method for monitoring the leakage of a hydraulic structure, which comprises a plurality of seepage monitoring modules distributed in the hydraulic structure, and the seepage monitoring modules include a first seepage monitoring unit distributed up and down, a left and right distribution The second seepage monitoring unit and the telescopic support connected with the first seepage monitoring unit and the second seepage monitoring unit at the same time, the first seepage monitoring unit and the second seepage monitoring unit are distributed with seepage measurement optical fibers, and the hydraulic engineering is monitored through the seepage measurement optical fibers Leakage status of the structure. A device for monitoring leakage of hydraulic structures of the present invention has the characteristics of no need for heating, distributed, and synchronous, and has outstanding advantages in reducing monitoring costs, improving monitoring accuracy, and engineering practicality; the monitoring method of the present invention adopts The seepage monitoring module is flexibly arranged in the hydraulic structure, and the position and direction of the seepage can be obtained by comparing the calibration optical fiber and the seepage measurement optical fiber. The operation is simple and the result is accurate.

Description

technical field

[0001] The invention relates to a positioning and directional monitoring of potential safety hazards of a hydraulic structure, in particular to a device and a monitoring method for monitoring leakage of a hydraulic structure. Background technique

[0002] More than 90% of embankment breaches in my country and more than one-third of the damage in earth-rock dam projects are caused by leakage and various problems derived from leakage. Seepage is an important factor and prominent disease that affects the safe and long-term service of hydraulic structures. Research and develop advanced and practical leakage location and orientation instruments, devices and identification methods to reliably detect the location, range, direction and size of leakage in hydraulic structures, and take effective anti-seepage and anti-seepage measures in a timely manner, which is of great significance to ensuring project safety extremely important.

[0003] At present, for the location ...
