Reservoir area anti-seepage geomembrane seepage overhauling device and overhauling method thereof

Abstract

The invention discloses a reservoir area anti-seepage geomembrane seepage overhauling device and an overhauling method thereof, and belongs to the field of hydraulic structure engineering applicationstudy. According to the reservoir area anti-seepage geomembrane seepage overhauling device and the overhauling method thereof, concrete anti-seepage walls are adopted to divide the bottom (the lower portion of an anti-seepage geomembrane) of the whole reservoir area into a plurality of small-area independent areas, a drainage blind ditch is arranged below the anti-seepage geomembrane of each areaand connected with a drainage pipe, and the drainage pipes are connected to flow monitoring equipment arranged outside the reservoir area; and after water storage of a reservoir, the water flow changes of the drainage pipes corresponding to the different independent areas in the reservoir can be observed to accurately judge the area where the anti-seepage geomembrane seeps, and accordingly the accurate geomembrane positioning and overhauling function can be achieved. By means of the reservoir area anti-seepage geomembrane seepage overhauling device and the overhauling method thereof, the waterseepage area after water accumulation can be accurately found, water is drained to the water seepage elevation position for repairing, accordingly, the anti-seepage geomembrane can be repaired, wastecaused by excessive water drainage can be avoided, the water seepage position can be accurately found without mistakes, and the water resource, capital and manpower are saved.

Description

technical field [0001] The invention relates to an anti-seepage geomembrane leak checking device and a checking method thereof in a reservoir area, and belongs to the application research field of hydraulic structure engineering. Background technique [0002] With the development of economy and society, the demand for water in various places is increasing, especially in castor and rocky desertification areas, and engineering water shortage has become the main reason that seriously restricts local development. The karst landform in Yunnan is relatively developed, and there are fewer and fewer areas with good reservoir storage conditions. Many reservoirs can only be built in places with poor geological conditions and leakage, and some reservoirs that have been built also exist For the problem of seepage in the reservoir area, the most common way to deal with seepage in the reservoir area is to lay geomembrane. However, due to the influence of various factors such as inadequat...

Problems solved by technology

The disadvantage is that it is difficult to find the damaged area of ​​​​the geomembrane (need to remove all prefabricated blocks), which consumes a lot of labor, materials and time, resulting in a lot of waste of water
