Title: Seepage water leak monitoring system for waste disposal site
Inventor: FUJITA TAKEYOSHI
IPC: G01M3/04
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To detect the damaged part of a waste disposal site by laying upper and lower sheet members over the whole area of the housing ground of the waste disposal site, partitioning the area into a plurality of monitoring sections, and guiding the seepage water and ground water leaked from a waste to a leaking layer between the upper and lower sheets in each monitoring section to a monitoring means through a seepage water pipe to monitor it. SOLUTION: In this seepage water leak monitoring system, the leaked state of seepage water is monitored by a leak monitoring pit 42 and a ground water monitoring pit 48. For example, when the upper sheet member of a monitoring section 32-1 is damaged or broken, the seepage water is leaked from a waste to a leaking layer. The leaked seepage water is carried from a collecting hole 38-1 to the leak monitoring pit 42 through a seepage water pipe 40-1. A disposal site manager can detect the damage of the monitoring area 32-1 by monitoring the seepage water. In the monitoring system, one end side is branched over the whole area of a disposal site ground 12 and guided to the ground water monitoring pit 48 by a ground water pipe 46. The manager can judge the inclusion of seepage water into ground water to detect a damage by inspecting and monitoring the water quality.

Title: Pressure filter device
Inventor: YABUTA NOBUYASU
IPC: B01D25/12
Filed: 1991-08-21
Abstract: PURPOSE:To effectively prevent the leaking out of an original liquid from the peripheral edges of filter cloths without acting an excessive initial pressing force on the filter cloths by increasing the pressing force that pressing devices press frame bodies to a filter cloth side with an increase in the pressurizing force on the original liquid injecting spaces of pressurizing bodies. CONSTITUTION:The pressing devices which press the frame bodies 9 to the filter cloth 4 side are provided. The pressing devices and the pressurizing bodies 8 are so connected as to increase the pressing force that the pressing devices press the frame bodies 9 to the filter cloth 4 side increase with an increase in the pressurizing force that the pressurizing bodies pressurize the original liquid injecting spaces 5. The reaction acting in the direction for parting the frame bodies 9 and the filter cloths 4 from each other increases naturally on increasing of the pressurizing force that the pressurizing bodies 8 pressurize the original liquid injecting spaces 5 at the start of the pressure filtration in this way, but the pressing force that the pressing devices press the frame bodies 9 to the cloth 4 side increases as well. Then, the initial pressing force for previously keeping the frame bodies 9 pressed to the peripheral edges of the filter cloths 4 prior to the start of the pressure filtration is minimized.
