Problems solved by technology
This approach is currently active in geomembrane leak measurement, but no one has yet applied it effectively to the problem of large-area geomembrane leak detection.
[0005] In large-area geomembrane projects such as anti-seepage at the bottom of the reservoir, after the reservoir is impounded and operated, if a certain geomembrane is damaged and causes leakage, it is difficult to measure the location of the geomembrane damage in a timely and effective manner, which is extremely difficult. The earth restricts the large-area use of geomembranes

Embodiment Construction
[0027] The technical scheme of the invention will be further described below in conjunction with the accompanying drawings.
[0028] Such as figure 1 and figure 2 The geomembrane shown is convenient for large-area leak detection, including the seamless splicing of multiple single geomembranes 1; the geomembrane is made of 2.0mm thick HDPE geomembrane, and the single geomembrane 1 is 5m wide and 100m long. Rows of geomembranes constitute a detection unit 101 , and each row has 5 single geomembranes 1 .
[0029] Such as image 3 and Figure 4 As shown, 8 electrodes 2 are preset at corresponding positions on the upper and lower surfaces of each single geomembrane 1, corresponding to two electrodes 2 forming a pair, 4 pairs in total, and the electrodes adopt ruthenium-plated titanium sheet electrodes (diameter 50mm, thickness 1mm ), said each electrode 2 is correspondingly connected to a wire 3, said each wire 3 is isolated by an insulating foreskin, and is attached to the su...

The invention discloses a geomembrane facilitating large area leakage detection. The geomembrane facilitating large area leakage detection is formed by splicing a plurality of single width geomembranebodies seamlessly; a plurality of electrodes are preset at the corresponding positions of the upper surface and the lower surface of each single width geomembrane body, and two corresponding electrodes form a pair; each electrode is correspondingly connected with a wire; the wires are mutually insulated, and are attached to the surfaces of the single width geomembrane bodies; the wire on each single width geomembrane body is connected to a circuit bus through a circuit branch; each single width geomembrane body corresponds to one circuit branch; and the terminal of the circuit bus is connected with an instrument disk and an external power source. The invention further discloses a geomembrane leakage detection method. According to the geomembrane facilitating large area leakage detection,during leakage detection, it is not needed to start a detection device all the time, energy is effectively saved, the detection device and the geomembrane are integrated, the measured position can beadjusted just by rotating a gear shifting knob during operation, and operation and construction are convenient.
Description
technical field [0001] The invention relates to a geomembrane leakage detection technology, in particular to a geomembrane which is convenient for large-area leakage detection and a leakage detection method thereof. Background technique [0002] Geomembrane has the advantages of small permeability coefficient, large elongation rate, good environmental protection benefits (compared to concrete and clay materials for seepage prevention), light weight and softness, easy construction, strong regional adaptability, high factory production quality assurance rate, and more convenient operation and maintenance. , In the field of anti-seepage, geomembranes are widely used in roof waterproofing and dam anti-seepage. And in recent years, with the development of geomembrane material science and the improvement of geomembrane performance, the application of geomembrane has become more extensive and the scale of use has become larger and larger. In some large-scale water conservancy proj...
