Abstract
A kind of tailings reservoir preliminary dam anti-filter Rotating fields, including permeable rock-fill dams, the domatic surface of upstream dam body of permeable rock-fill dams is equipped with the first nonwoven reinforced geotextile, blotter is filled in the first nonwoven reinforced geotextile surface, the first sand gravel layer has been filled on blotter surface, first sand gravel layer surface is equipped with the second nonwoven reinforced geotextile, and the second sand gravel layer has been filled on the second nonwoven reinforced geotextile surface, and the second sand gravel layer surface is provided with and grouts rock layers pitching；Even if two-layer nonwoven reinforced geotextile is able to ensure that another layer still can play benefit in the case of a damage layer; the drainage rich in mine tailing is reduced to leak risk; the gravel of two-layer sand gravel layer selects different-grain diameter for drainage Contents of Tailings; the working effect of loaded filter can be improved; grouting rock layers can protect anti-filter structure; the utility model prevents the drainage that Tailings Dam occurs being rich in mine tailing at the slag stacking initial stage from leaking, and remains to effectively filter mine tailing infiltration after faint sedimentation occurs in dam body.
Description
Technical field
The utility model is related to Tailings Dam to build field of engineering technology, more particularly to a kind of tailings reservoir preliminary dam loaded filter knot
Structure.
Background technology
At present in the numerous Tailings Dam of China, its initial dam is built a dam more than mode in the form of permeable rock-fill dams, therefore
Such permeable rock-fill dams has more strict requirements to the drainage effect that slag stacks the initial stage, forbids to go out at the slag stacking initial stage
Existing " running muddy " phenomenon, prevents from polluting downstream ecology environment, destroys.Further, since building a dam the initial stage, tailing dam easily occurs
Faint sedimentation, easily cause it is counter consider Rotating fields and fracture belt occur, drainage of the aggravation rich in mine tailing leaks.Therefore a kind of performance is developed
More excellent, the anti-filter Rotating fields opposite state environmental protection for being prevented from excessive tailings occur in drainage is particularly important.
The content of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is that a kind of tailings reservoir preliminary dam of offer is anti-
Structure of filtering layer, prevents Tailings Dam from stacking drainage of the initial stage appearance rich in mine tailing in slag and leaks, after faint sedimentation occurs in dam body
Remain to effectively filter mine tailing infiltration.
In order to achieve the above object, the utility model is adopted the technical scheme that：
A kind of tailings reservoir preliminary dam anti-filter Rotating fields, including permeable rock-fill dams 1, the upstream dam body of permeable rock-fill dams 1 are domatic
Surface is equipped with the first nonwoven reinforced geotextile 2, and blotter 3 has been filled on the surface of the first nonwoven reinforced geotextile 2, in rubble pad
The first sand gravel layer 4 has been filled on 3 surface of layer, and the surface of the first sand gravel layer 4 is equipped with the second nonwoven reinforced geotextile 5, the second nothing
Spin the surface of reinforced geotextile 5 and filled the second sand gravel layer 6, the surface of the second sand gravel layer 6 is provided with and grouts the pitching of rock layers 7.
The first described nonwoven reinforced geotextile 2 is 500g/m2And paste fiberglass gridding in non-woven geotextile both sides
Material.
The ballast grain sizes of described blotter 3 are 2~10mm, and laying depth is 200mm, and the laying gradient is not less than saturating
The upstream dam body of water-water reactor masonry dam 1 is domatic.
The described thickness 200mm of the first sand gravel layer 4, the gradient is domatic not less than the upstream dam body of permeable rock-fill dams 1, gravel grain
Footpath is 5~20mm.
The second described nonwoven reinforced geotextile 5 is identical with the material of the first nonwoven reinforced geotextile 2, with identical mechanics
Performance.
The described thickness of the second sand gravel layer 6 is 200mm, and grain size of gravel is 2~10mm.
Described grouts the thickness of rock layers 7 for 300mm.
The beneficial effects of the utility model：
(1) due to there is preferable mechanical property using two-layer nonwoven reinforced geotextile, it is possible to successfully manage due to
Generation " race muddy " phenomenon of the faint sedimentation institute of dam body；Grouting rock layers 7 can be to the effective protection of loaded filter.
(2) due to using two-layer nonwoven reinforced geotextile, it is ensured that even if another layer still can in the case of a damage layer
Benefit is played, gravel layer uses different gradation according to Contents of Tailings in drainage and the priority contacted with drainage, it is possible to having
Effect reduces drainage Contents of Tailings.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Make narration in detail to the utility model below in conjunction with the accompanying drawings.
Reference picture 1, a kind of tailings reservoir preliminary dam anti-filter Rotating fields, including permeable rock-fill dams 1, first to permeable rock-fill dams 1
Upstream dam body is domatic to carry out smooth, and the domatic surface of upstream dam body of permeable rock-fill dams 1 is equipped with the first nonwoven reinforced geotextile 2,
After the completion of laying, blotter 3 has been filled on the surface of the first nonwoven reinforced geotextile 2, after the completion of blotter 3 is filled, in rubble
The first sand gravel layer 4 has been filled on the surface of bed course 3, after the completion of the first sand gravel layer 4 is filled, the more prominent gravel in its surface is entered
Row leveling, the surface of the first sand gravel layer 4 is equipped with the second nonwoven reinforced geotextile 5, and the surface of the second nonwoven reinforced geotextile 5 is filled
There is the second sand gravel layer 6, the surface of the second sand gravel layer 6 is provided with and grouts the pitching of rock layers 7.
The first described nonwoven reinforced geotextile 2 is 500g/m2And paste fiberglass gridding in non-woven geotextile both sides
Material, improve its toughness, the material has preferable mechanical property, can effectively prevent hard material from being destroyed to it.
The ballast grain sizes of described blotter 3 are 2~10mm, and laying depth is 200mm, and the laying gradient is not less than saturating
The upstream dam body of water-water reactor masonry dam 1 is domatic.
The described thickness 200mm of the first sand gravel layer 4, the gradient is domatic not less than the upstream dam body of permeable rock-fill dams 1, gravel grain
Footpath is 5~20mm.
The second described nonwoven reinforced geotextile 5 is identical with the material of the first nonwoven reinforced geotextile 2, with identical mechanics
Performance.
The described thickness of the second sand gravel layer 6 is 200mm, and grain size of gravel is 2~10mm, because the layer is the first anti-filter
Layer, so the gravel of selection of small particle diameter.
