Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Please combine figure 1 . In the block-based rapid detection device for leakage detection in landfills of the present invention, a transmitting electrode 1 is placed in the protective layer A on the geomembrane of the landfill, a receiving electrode 2 is placed in the soil under the geomembrane, and the emission The two ends of the signal source 3 are connected between the electrode 1 and the receiving electrode 2 .

[0022] Multiple detection electrodes 4 are placed in the protective layer A (or the drainage layer or the shallow garbage layer), and the detection electrodes 4 are respectively connected to the data acquisition and processor 5, and the vulnerability location is performed by detecting the potential difference of each point.

[0023] In practical applications, the protective layer A can also be a drainage layer or a relatively shallow garbage la...

Abstract

A device for checking rapidly leakage detecting block gasification of landfill is provided. An emitting electrode is placed in protection layer of geomemberance of landfill, and a receiving electrode is placed in the soil under the film of geomemeberance, two ends of signal source are connected between emitting electrode and receiving electrode. Multiple detecting electrode are placed in protection layer, each of which is connected with data collecting processor respectively, orientating by detecting the electric potential difference of each point. Signal is connected with data collecting processor and controlled by said data collecting processor. Each detecting electrode signal is added to active low pass filter after low pass filtering and transient suppression, output signal is entered analog-to-digital converter to transmit, data of each point is carried on leak judgement and the corresponding coordinate position is showed on display. The device of present invention has advantages of high speed detecting, high veracity and high omission factor.

Description

technical field [0001] The invention relates to a leakage detection device used in landfill sites, in particular to a block-based rapid detection device for leakage detection in landfill sites. Background technique [0002] In order to prevent the groundwater from being polluted, the anti-seepage lining system of the landfill is an essential facility for the construction of the landfill. Its function is to isolate the inside and outside of the landfill and control the leachate from entering the clay and groundwater. The general materials of this system mainly include clay and artificial synthetic materials. The most commonly used artificial synthetic material is high-density polyethylene (HDPE). In the investment of landfill construction, the investment in anti-seepage layer is huge. Due to the quality of HDPE itself or construction reasons, the anti-seepage layer of the landfill is often damaged. Relevant data show that the probability of the geomembrane being damaged after...
