Application of Micro-seepage Field Detection in Reservoir Leakage Treatment
Leakage is a key factor affecting the safety of reservoir dams. In view of the problems which is difficult to accurately locate the leakage point of reservoir dams and the inaccurate measurement of leakage volume, this paper describes the principle of sonar velocity measurement, introduces the micro-seepage field detection technology, and successfully applied in Banqiao Reservoir. Through the ‘DB-VI three-dimensional velocity vector sonar measuring instrument’, the crack leakage passage of Banqiao Reservoir concrete spillway dam is detected, and the size and distribution of the acoustic energy transfer in the fluid are measured. At the same time, combined with underwater camera verification, the leakage site was determined, the leakage entrance was located, and the leakage amount of each part was calculated, which provided a basis for taking targeted treatment measures.
