Description

Red mud Tailings Dam composite anti-penetrating structure
Technical field
The present invention relates to the processing of Tailings Dam, more particularly to a kind of red mud Tailings Dam composite anti-penetrating structure.
Background technology
The raw material of aluminum smelting industry is usually bauxite, remaining remaining mineral after being extracted to the active ingredient of bauxite Residue is Aluminum mine tailing, normally referred to as red mud.Red mud is that a kind of particle of red similar soil forms material, its mineral Form more complicated, mainly contain the mineral matters such as aluminum oxide, iron oxide and silica, typically exhibit stronger alkalescence and corrosion Property.Due to red mud and wherein liquid body exudate (wastewater from red mud) has strong basicity and corrosivity, and it has very strong destructiveness to environment, Pair there is very havoc power with the animals and plants closed on, therefore the safe stockpiling problem of red mud seems and is even more important.Store up the place of red mud As Aluminum Tailings Dam or red mud Tailings Dam, in southwest, usual addressing makes full use of landform nature Cheng Ku in mountain area, then auxiliary Help progress is necessary manually to build a dam.It is its stability and permeability resistance for the problem of reservoir area and dam body maximum, wherein again with steady Qualitative question is attached most importance to, once red mud Tailings Dam dam break, a large amount of red muds and wastewater from red mud will leak, and this can be to the life of neighbouring resident Property safety and surrounding enviroment cause huge threat.In order to prevent the outside seepage of the harmful substance in industrial tailings from being made to soil Into pollution, so to carry out Anti-seeping technology to industrial tailings, antiseepage cloth is set generally in massif side slope, covered on antiseepage cloth Certain thickness yellow clay makes real, it is therefore an objective to avoids antiseepage cloth from being directly exposed in atmospheric environment, prevents from making because exposing to the weather The too fast aging of antiseepage cloth, but during practice of construction, due under the influence of slope height and soil self gravitation, covering The effect that antiseepage cloth in side slope can be torn, particularly when abundant rainfall, the soil that is covered on antiseepage cloth Easily it is washed, antiseepage cloth is easily damaged, and directly affects anti-seepage effect.
The content of the invention
In view of this, it is an object of the invention to provide a kind of red mud Tailings Dam composite anti-penetrating structure, used antiseepage Material Physics, stable chemical performance, cryogenic property, ageing resistace are excellent, and right angle tear resistance is strong, and joint reliability is high, whole Individual impervious barrier structural strength is high, has very strong tensile strength and elongation percentage, to adapt in large-area storage yard locally to sandstone Anti- top wear intensity, it is ensured that wastewater from red mud will not penetrate into underground during use in stockyard.
The red mud Tailings Dam composite anti-penetrating structure of the present invention, including the impervious barrier being arranged in side slope and it is arranged at impervious barrier On flexible cover sheet and the rigid course that is arranged at below impervious barrier, also set up between the rigid course and impervious barrier There is separation layer, the separation layer is mixed by wheat straw or straw with clay, and the antiseepage layer material includes following by weight Component:20-30 parts makrolon, 10-20 parts polytetrafluoroethylene (PTFE), 5-12 parts polybutylene terephthalate, 10-15 part fine coal Ash, 1-10 part sledge mills glass, 1-5 part graft copolymerizations acrylic acid derivative, 1-5 parts antioxidant, 0.5-3 parts ultra-violet absorber, 1-3 part age resistor;
