Earth and rockfill dam leakage hidden danger detection directional processing system and method

Abstract

The invention relates to an earth and rockfill dam leakage hidden danger detection directional processing system and method. The system comprises an electrical prospecting instrument, a cable, electrode plugs, a power supply and an electromagnetic induction device. The electrode plugs comprise a first electrode plug and a plurality of second electrode plugs, and the first electrode plug and the second electrode plugs are connected to two electrode output ends of an electrical prospecting instrument through cables; the electrical prospecting instrument is used for emitting electrical signals with different frequencies and forming a geological three-dimensional graph according to the first electrode plug and the second electrode plugs; the power supply is used for supplying power to the electrical prospecting instrument; and the electromagnetic induction device is used for detecting a magnetic field generated by current between the first electrode plug and the second electrode plugs. The system and method have the effect of detecting the leakage trend of the earth and rockfill dam before leakage of the earth and rockfill dam occurs.

Description

technical field [0001] The present application relates to the technical field of detection, and in particular to a system and method for detecting and directional processing of hidden dangers of earth-rock dam leakage. Background technique [0002] my country has a vast land with numerous river channels and reservoirs, among which earth-rock dams account for more than 80%. Most of the reservoir dams were built in the 1950s to 1970s. After years of operation, the hydraulic structures of the reservoir dams are naturally aging. Some reservoir dams have even experienced natural disasters, plus factors such as untimely management and maintenance. Gradually, hidden dangers such as dam body leakage, structural defects and metal structure corrosion have emerged, which seriously threaten the safety of the reservoir dam and human life. [0003] In related technologies, some detection methods realize the detection of earth-rock dams by detecting the degree of change in the shape of th...

Problems solved by technology

Most of the reservoir dams were built in the 1950s to 1970s. After years of operation, the hydraulic structures of the reservoir dams are naturally aging. Some reservoir dams have even experienced natural disasters, plus factors such as untimely management and maintenance. Hidden problems such as dam body leakage, structural defects and metal structure corrosion have gradually appeared, seriously threatening the safety of the reservoir dam and people.

[0003] In related technologies, some detection methods realize the detection of earth-rock dams by detecting the degree of change in the shape of the earth-rock dam or by using temperature sensing imaging methods, but these methods can only be discovered or detected after the deformation or leakage of the earth-rock dam occurs. When the earth-rock dam Before the leakage occurs or when there is a hidden danger of leakage, it cannot play the role of detection
