摘要

Device for simulation of the thermo-hydromechanical behavior of barriers of fine materials, for the waterproofing and sealing of landfills. The present invention consists of a confinement enclosure (1), materialized in a frame of reinforced concrete open top, which supports the hearth on steel pillars (2). On the basis materialized in grid plates (3) made of steel, the material (4) to be analyzed is arranged and compacted. Under this plate (3) is placed a tray (5) that collects leachates. On its upper embouchure there is a system of irrigation of nebulizer nozzles (7) controlled by a programmable automaton (8), which simulates natural thermo-hydro-pluviometric conditions. During the compaction process, electronic sensors (11-12) that collect periodic readings on the moisture content, temperature and other relevant parameters are distributed within the material. The device allows to know behaviors of materials of fine granulometry arranged in layers according to their ability to delay the migration of water, to sample and characterize the quality of the percolating fluid, to evaluate its longevity and deterioration mechanisms.
