Seeping hidden trouble detection and directional processing method and detection equipment for earth and rockfill dam

Abstract

The invention relates to the field of reservoir reinforcement, and specifically belongs to a seeping hidden trouble detection and directional processing method and detection equipment for an earth and rockfill dam. Aiming at a problem that most of earth and rockfill dams in current water conservancy engineering have a problem of seepage, the invention provides a directional processing method integrating seepage inspection and seepage blocking. The objectives of the invention lie in judging an electrical property abnormal area of a seeping channel according to the testing result of the resistivity of the earth and rockfill dam, interpreting the specific distribution of hidden troubles through combining the technical data of the operation of the reservoir, carrying out the reasonable guide of subsequent reinforcement operations, optimizing the grouting technology, avoiding the blindness of seeping blocking construction, remarkably improving the project benefit and winning social reputation. The method and equipment are advantageous in that the method and equipment introduce the latest parallel electrical method detection technology into the seepage detection of the earth and rockfill dam, carry out reasonable grouting according to a detection result, achieve the integration of hidden trouble inspection and processing, and achieve a purpose of quick directional processing.

Description

technical field [0001] The invention relates to the field of reservoir reinforcement, specifically belongs to an earth-rock dam leakage detection method and a directional processing technology, and further relates to a directional processing method and detection equipment combining the parallel electrical leakage detection technology and grouting plugging. It is mainly suitable for hidden leakage detection and plugging treatment of reservoirs, ponds, embankments, tailings dams and other projects. Background technique [0002] Earth-rock dams are water-retaining facilities whose main structure is composed of homogeneous clay or core walls, and are widely distributed in the form of reservoirs or mountain ponds. Most of the earth-rockfill dams in my country were built from the late 1950s to the early 1970s. Due to the technical and economic conditions at that time, a considerable number of reservoirs or ponds had leakage problems after years of operation. Leakage of reservoirs...

AI Technical Summary

Problems solved by technology

[0003] Leakage channels of earth-rock dams are concealed projects, and spatial information such as the location, depth, shape, and scale of hidden dangers are not easy to grasp, resulting in blindness in hazard elimination and reinforcement, and even some reservoirs have not seen any leakage after repeated repairs and reinforcements. change, resulting in bad social impact
