In order to prevent the groundwater from being polluted, an impermeable layer system of the landfill site is an indispensable facility for the construction of the landfill site. In recent years, high-density polyethylene films are generally adopted as the anti-seepage layers of the refuse landfills in China, but the high-density polyethylene films are easy to leak due to the influence of various factors in the construction and later use processes of the landfills. If the leakage is not discovered and repaired in time, the seepage-proofing effect of the engineering is inevitably influenced by the leakage, and the landfill leachate enters underground water and soil through the damaged leakage to pollute the surrounding water and soil environment, so that the leakage problem of the landfill site is more and more emphasized.
At present, the leakage detection of the refuse landfill in the prior art is completely realized through manual detection, and aiming at a high-density polyethylene film paved with gravel or sand and a cement layer, a commonly adopted method is a double-electrode detection method, workers need to follow the detection process at all times, and when a leak occurs, the workers perform marking and positioning. In recent years, with the gradual increase of the area of a refuse landfill, the method causes large workload of workers and low detection efficiency.
