Abstract
The utility model discloses a seepage control structure used in red mud disposal sites. The seepage control structure comprises a protective layer, a main seepage control layer, an auxiliary seepage control layer and a base layer, wherein, the protective layer, the main seepage control layer, the auxiliary seepage control layer and the base layer are arranged from the top down in sequence; the protective layer is made of filament non-woven geotextile; the main seepage control layer is made of HDPE geomembrane; the auxiliary seepage control layer comprises a sodium bentonite blanket; the base layer comprises a compacted foundation; and the side slope of a disposal site adopts geomembrane on the roughened surface according to the slope thereof. The utility model has the advantages that the HDPE geomembrane is relatively moderate in price, light in weight, wide in breadth, easy to weld, high in welding strength, and less vulnerable to high-temperature alkali liquor; and as the side slope of the disposal site adopts the geomembrane on the roughened surface according to the slope thereof, the friction force between the geomembrane and the side slope can be enhanced, and the stability can be enhanced.
Description
Technical field
The utility model relates to a kind of leakage preventing structure, particularly relates to a kind of leakage preventing structure that is used for red mud dump.
Background technology
Along with the develop rapidly of China's aluminium industry, the discharge value of red mud is also increasing suddenly.Data show according to the relevent statistics, and the red mud of 1 ton of alumina discharging of every production is up to 1.0～1.45 tons.Main component is iron oxide, calcium oxide etc. in the red mud, and itself moisture content can not produce other gases than higher in the process of storing up, if do not take seepage control measure, these red muds and attached liquid thereof will severe contamination downstream underground water and surface water.In addition, red mud is stored, can fully utilize.At the characteristic of red mud, adopt suitable seepage control technique, solve the harm that it causes environment.
The utility model content
The utility model aims to provide a kind of leakage preventing structure that Bayer process, sintering process, combination method refine the red mud dump of discharging behind the alumina that is used for.
The utility model is a kind of, and to be used for the technical scheme of leakage preventing structure of red mud dump as follows:
A kind of leakage preventing structure that is used for red mud dump of the utility model from top to bottom is topping, main impervious barrier, auxiliary seepage proof layer and basal layer successively; Described topping is made of the long filament non-woven geotextile; Described main impervious barrier is made of the HDPE geomembrane; Described auxiliary seepage proof layer is made of the sodium bentonite blanket; Described basal layer is made of rammed subgrade; Described storage yard slope adopts coarse-surface geomembrane according to the gradient.
Underground water can be set under described basal layer collect the guide system.
The utility model is a kind of, and to be used for the beneficial effect of leakage preventing structure of red mud dump as follows:
The leakage preventing structure that the utility model is a kind of to be used for red mud dump adopts the HDPE geomembrane as main impervious material, and price is moderate relatively, light weight, fabric width are big, be easy to welding, weld strength is big, it is little influenced by high temperature alkaline solution;
A kind of storage yard slope that is used for the leakage preventing structure of red mud dump of the utility model adopts coarse-surface geomembrane according to the gradient, improves the frictional force of geomembrane and side slope, enhanced stability.
Description of drawings
Fig. 1 is a kind of schematic diagram that is used for the leakage preventing structure of red mud dump of the utility model;
1, red mud, 2, topping, 3, main impervious barrier, 4, the auxiliary seepage proof layer, 5, basal layer, 6, underground water collects the guide system.
The specific embodiment
Referring to accompanying drawing 1, a kind of leakage preventing structure of red mud dump that is used for of the utility model is by under last being topping 2, main impervious barrier 3, auxiliary seepage proof layer 4 and basal layer 5 successively; Described topping 2 is made of the long filament non-woven geotextile; Described main impervious barrier 3 is made of the HDPE geomembrane; Described auxiliary seepage proof layer 4 is made of the sodium bentonite blanket; Described basal layer 5 is made of rammed subgrade; Described storage yard slope adopts coarse-surface geomembrane according to the gradient.
The described leakage preventing structure that is used for red mud dump is provided with underground water and collects guide system 6 under described basal layer.
When using a kind of leakage preventing structure that is used for red mud dump of the utility model, red mud 1 is stacked on the topping 2,
Claims (2)
1. a leakage preventing structure that is used for red mud dump is characterized in that: by under last being topping, main impervious barrier, auxiliary seepage proof layer and basal layer successively; Described topping is made of the long filament non-woven geotextile; Described main impervious barrier is made of the HDPE geomembrane; Described auxiliary seepage proof layer is made of the sodium bentonite blanket; Described basal layer is made of rammed subgrade; Described storage yard slope adopts coarse-surface geomembrane according to the gradient.
