A BED STRUCTURE FOR DEPOSITION OF REFUSE AND OTHER WASTE MATERIALS

摘要

A bed structure for deposition of refuse and other waste materials comprises a pair of vertically spaced upper and lower liners or membranes (11, 12) and an intermediate layer (13) of porous material arranged between the liners. Electrical moisture detecting means (20, 30), which may comprise electrical conductors arranged like a square grid, are positioned between the liners. Because the intermediate layer (13) is normally isolated from percolate contained in the refuse or waste materials and from ground water, the moisture detecting means may detect even a small leakage in the upper or lower liner or membrane (11, 12) through which percolate or ground water may flow into the intermediate layer (13).
