Red mud storage yard anti-seepage structure
The invention discloses a red mud storage yard anti-seepage structure. The structure comprises an anti-seepage layer, a flexible protection layer arranged above the anti-seepage layer and a rigid protection layer arranged below the anti-seepage layer. The flexible protection layer is in a net structure. Anti-seepage layer materials comprise polycarbonate, polytetrafluoroethylene, pulverized fuel ash, hammer mill glass fibers, polyacrylic acid-2-ethylhexyl ester, antioxidants, ultraviolet light absorption agents and anti-aging agents. According to the anti-seepage materials that are used, the heat resistance, the cold resistance and the chemical stability are good, rigidity and toughness are high, mechanical strength is good, environmental stress cracking resistant and tearing strength resistant performances are good, the mechanical performance and the barrier performance are improve correspondingly along with the rising of the density, and the heat resistance and the tensile strength are better; the structure is resistant to corrosion of acid, alkali, organic solvents and the like, provided with outstanding anti-aging, uvioresistant and anti-decomposition capacities, capable of being exposed, high in right-angle tear resistance, joint reliability and whole anti-seepage layer structure strength and provided with high tensile strength and elongation percentage, so that the structure can be adapted to the anti-jacking strength of the locality to dinas in large-area storage yards, and the red mud waste cannot seep into underground when storage yards are used.
