Title: Detection method of water leakage amount for water shielding sheet of waste disposal yard
Inventor: DOI YOICHI
IPC: G01M3/20
Filed: 1993-01-21
Abstract: PURPOSE:To enable the detection of a water leakage amount by a method wherein electrodes are arranged on upper and lower surfaces of a water shielding sheet at a specified interval while a plurality of electrolyte injection pipes are arranged on the upper surface and an electrolyte is injected from the injection pipe on the upstream side thereof following the detection of the position of a water leaking position to detect a changing speed of electroconductivity between the electrodes. CONSTITUTION:When a water shielding sheet 1 tears and a water leaking position 3 is detected from changes in electric characteristics between linear electrodes 2-1 and 2-2, an electrolyte is injected from an injection pipe 4 on the upstream side thereof. In the injection, a packers 6 and 6 are reduced to be moved through the injection pipe 4 and arranged at the position the nearest the water leaking position 3. Then, the packer 6 is expanded by a pressure air to limit an injection width to the length of the packers 6 and 6. When the electrolyte such as salt or ammonium chloride is injected, it flows bit by bit in the direction of the water leaking position 3 on a flow of the water leaked and electroconductivity rises between the linear electrode 2-1 and the linear electrode 2-2 on the underside of the sheet 1. Thus, the water leakage value can be detected by measuring the time DELTAt until the electroconductivity becomes stable.
