چکیده | ||
Landfill is the major method of solid waste disposal in developing countries. To protect soil and groundwater from contamination, anti-seepage systems have to be installed in landfills. However, during the construction of anti-seepage system, many factors can result in holes in geomembrane liners. For the purpose of improving construction quality, the construction company needs to find the leaks in geomembrane liners and analyze the damage causes according to the positions after construction. The electrical method can effectively test the integrity of geomembrane liners. In this paper, we combine the electrical method with the wireless location technology and bring forth a leak marking scheme. The working flow of the scheme is as follows: place two acoustic transceivers on two vertexes s of the detection area; after detecting the leaks with the electrical method, calculate the leaks’ relative coordinates in the detection area through acoustic ranging and, then, mark positions of leaks in the landfill. At last, we design acoustic signals for ranging, analyze their performance on anti-interference, and design the leak marking algorithm. | ||
