Device for simulating the behavior thermo-hydro-mechanical barriers fine materials for waterproofing and sealing of landfills.

摘要

Device for simulating the behavior of thermal barriers hydromechanical fine materials, waterproofing and sealing of landfills.; The present invention consists of a containment enclosure (1), embodied in a reinforced concrete frame open at the top, which supports the hearth pillars (2) of steel. Based on slatted materialized plates (3) of steel it is provided and compacts the material (4) to be analyzed. Under this plate (3) a tray (5) is placed collecting leachates. On its upper mouth watering system of spray nozzles (7) controlled by a programmable automaton (8), which simulates conditions thermo-hydro-pluviometric natural stands. During the compaction process are distributed within the electronic equipment sensors (11-12) that collect periodic readings of moisture content, temperature and other relevant parameters. The device provides behaviors of fine granulometry materials arranged in layers according to their ability to delay the migration of water sample and characterize the quality of percolating fluid assess their longevity and decay mechanisms.
