Embodiment Construction

[0050] Aiming at the seepage phenomenon of earth-rock dams, the present invention proposes a danger-eliminating and fixed-direction treatment technology integrating leak detection and anti-seepage. The purpose and treatment method are more clear, and the grouting reinforcement treatment project can be realized in a targeted manner, and the monitoring and information feedback system in the treatment process can help the local improvement of the method of risk elimination.

[0051] For further specifically introducing the use of this invention, the specific implementation is as follows:

[0052] like figure 1 , according to the exposure of the seepage point behind the dam, combined with the pre-reservoir background data and site characteristics, an electrical measuring station 4 is arranged on the earth-rock dam. , generally 3 to 4, of which the dam crest measuring station is preferentially arranged on the post-reinforcement axis, and each test line (electrical method measuring...

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...
