Once there is seepage in certain position in system, if making up not in time, can cause large underground area water pollution, will give industrial and agricultural production and
People's lives and properties cause huge disaster and loss.
In the prior art, the drainage system of Tailings Dam is laid less perfect, and seepage once occurs in pipeline, is leaked out to from discovery
The overlong time that contaminated water is handled is completely drawn out, larger range of pollution can be caused, while also increase the place of sewage
Manage cost.Therefore Tailings Dam drainage system deposits certain hidden danger.
Utility model content
For in place of above shortcomings in the prior art, the utility model is a kind of drainage system of Tailings Dam.
Used technical scheme is the utility model to achieve the above object：A kind of Tailings Dam drainage system, the row
Water system is placed in gutter, wraps up the second filtering impervious barrier and the first filtering impervious barrier, institute successively in the outside of draining floral tube
Stating the second filtering impervious barrier includes the second anti-seepage geotextile and is bonded the draining floral tube with coarse sand gravel, the band coarse sand gravel
Outside, the second anti-seepage geotextile of the band coarse sand gravel outer wrap；The first filtering impervious barrier includes the first antiseepage soil
Work cloth and gravel burning into sand, the gravel burning into sand are bonded the outside of second anti-seepage geotextile, the gravel burning into sand outer wrap
First anti-seepage geotextile.
The second steel plastic geogrid is provided between second anti-seepage geotextile and draining floral tube, the band coarse sand gravel is put
In each grid inside second steel plastic geogrid.
It is described uniformly to be placed in each grid inside second steel plastic geogrid with coarse sand gravel.
The first steel plastic geogrid, the gravel folder are provided between second anti-seepage geotextile and the first anti-seepage geotextile
Sand is placed in each grid inside first steel plastic geogrid.
The gravel burning into sand is uniformly placed in each grid inside first steel plastic geogrid.
The utility model has advantages below and beneficial effect：
The utility model is improved to existing drainage system.Both geotextiles and GSZ used, which combine, to be made
With can make enhancing encapsulation, prevent the problem of anti-seepage effect is bad, reduce the scope of contaminated underground water.
It is of the present utility model to use two layers of filtration, filtered by two layers of filtration, and put in filter layer
Two kinds of different fillers of infiltration coefficient are put, seepage can be effectively prevented and reduce the pollution to underground water.
Brief description of the drawings
Fig. 1 is the utility model in overall structure figure；
Wherein, 1 it is gutter, 2 be the first anti-seepage geotextile, 3 be the second anti-seepage geotextile, 4 be draining floral tube, 5 is
One steel plastic geogrid, 6 be the second steel plastic geogrid, 7 be band coarse sand gravel, 8 be gravel burning into sand.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.
As shown in figure 1, determined first according to factors such as Tailings Dam geological condition and requirements by technology and economy comparison
Region quantity.The present embodiment is divided into a region.A kind of Tailings Dam draining system, the drainage system are placed in gutter 1, are being arranged
The second filtering impervious barrier and the first filtering impervious barrier are wrapped up in the outside of spray pipe 4 successively, and the second filtering impervious barrier includes the
Two anti-seepage geotextiles 3 and with coarse sand gravel 7, the outside that the draining floral tube 4 is bonded with coarse sand gravel 7, the band coarse sand
The second anti-seepage geotextile of outer wrap 3 of gravel 7；The first filtering impervious barrier includes the first anti-seepage geotextile 2 and gravel burning into sand
8, the gravel burning into sand 8 is bonded the outside of second anti-seepage geotextile 3, the first antiseepage of outer wrap of gravel burning into sand 8 soil
Work cloth 2.The second steel plastic geogrid 6, the band coarse sand gravel 7 are provided between second anti-seepage geotextile 3 and draining floral tube 4
It is placed in each grid inside second steel plastic geogrid 6.The band coarse sand gravel 7 moulds geotechnological lattice in second steel
Uniformly placed in each grid inside grid 6.First is provided between the anti-seepage geotextile 2 of second anti-seepage geotextile 3 and first
Steel plastic geogrid 5, the gravel burning into sand 8 are placed in each grid inside first steel plastic geogrid 5.The gravel
Burning into sand 8 is uniformly placed in each grid inside first steel plastic geogrid 5.
The specific mode of operation of the utility model is as follows：
When excavated volume reaches size requirement when gutter 1, designed first anti-seepage geotextile 2 is laid.Anti-seepage geotextile
Using plastic sheeting as antiseepage base material, and the non-woven fabric compounded seepage by geo-textile material formed, main function be punctured resistance it is high,
There is preferable erosion resisting, have good effect in acid, the erosion of alkali salt class, adaptation ambient temperature range is big, anti-drainage performance is fabulous.
The first steel plastic geogrid 5 is laid on the first anti-seepage geotextile 2, steel plastic geogrid is passed through by high-tensile steel wires
High density polyethylene (HDPE) is rolled into high strength tapes, at a right angle by plane longitude and latitude, the geosynthetics being molded through ultrasonic bonding.
Its characteristic resistant to corrosion, it will not be dissolved by water or microorganism is encroached on.The aging caused by ultraviolet radiation can be resisted.Completely may be used
To meet the requirement of permanent work construction.
Gravel burning into sand 8 is placed in each grid inside the first steel plastic geogrid 5 laid, infiltration coefficient is
Between 75-150.Lay one layer of second anti-seepage geotextile 3 again on gravel burning into sand 8, be further continued for laying the second steel plastic geogrid
6, the deposit belt coarse sand gravel 7 in each grid inside the second steel plastic geogrid 6, infiltration coefficient of this layer with coarse sand gravel
For 100-200.
Draining floral tube 4 is finally placed, outermost first anti-seepage geotextile 2 is then connected into closure around draining floral tube
Body.
The geotextiles that the utility model uses are used for water-impervious, and GSZ is used for reinforcing, and the two is used in combination, can
Make enhancing encapsulation, prevent the downslide with coarse sand gravel 7 and gravel burning into sand 8 in encapsulation process from causing integument middle and upper part antiseepage effect
The problem of fruit is bad.
It is of the present utility model to use two layers of filtration, when draining floral tube 4 produces leakage, entered by two layers of filtration
Row filtering, and Anti-seeping technology is carried out by two layers of anti-seepage geotextile, effectively reduce the pollution to underground water.This drainage system
It after use, can also determine whether water pipe has seepage according to related monitoring device, and poluted region underground water is individually taken out in time
Return plant area's processing.
