Abstract
The utility model belongs to the technical field of mine abandonment ground ecological remediation, concretely relates to acid spoil site side slope ecological remediation's compound isolation layer structure. The utility model aims to solve the technical problem that an ecological prosthetic isolation layer structure of acid spoil site side slope is provided, including two-way geogrid of plastics and polyethylene drain bar, still include soil improvement layer between two-way geogrid of plastics and the polyethylene drain bar, two-way geogrid of plastics, soil improvement layer and polyethylene drain bar pass through the stock to be fixed on domatic. The utility model discloses effectively solved the situation that acid spoil site side slope plant is difficult to grow, built the environment of plant good growth, construction process maneuverability is strong, has embodied the characteristics that engineering protection and ecological protection combined together.
Description
Technical field
The utility model belongs to abandoned land ecological reestablishment field, mine, is specifically related to the compound insulation layer structure that a kind of acid waste-rock yard slope ecological is repaired.
Background technology
It is very big that China's non-ferrous metal is composed the ratio that is stored in the mineral with sulfide, is equivalent to 3/4 of all kinds of mineral species total amounts approximately.In mineral mining, sulphide ore produces a large amount of overburdens.Under the condition of banking up in the open, the quite high sulfide that in this class mine discarded object there is remaining different content easily by the oxidation of airborne oxygen institute, is met rainfall and water, forms strong acid water, and a large amount of heavy metal ion of carrying under one's arms.As unreasonable disposal, will become the serious harmful pollution sources in mining area.In fact, China is perplexed by this pollution problem in many mines for many years, and acid pollution is very serious.The hillock that has, close many decades and still be sharp sourness, not even a blade of grass grows on the face of land, sets up the vegetation difficulty, have in addition pollute and have influence on surface water, underground water and soil around the mining area, caused the rugged environment influence.No matter China's land reclamation work is reclaim scientific research, the technology of reclaiming, the scale of reclaiming, still the level of reclaiming is still not high, reclaiming with external advanced person, to compare gap bigger in country, rests on mostly on the simple ground works link, and the ecology recovering technical research of sulphide ore discarded object stockyard is also more backward.How fundamentally to prevent from or stop substantially from discarded stockyard to produce acid pollution, this still is the problem that faces during the mine abandoned land recovers.Relate to also that the generation of waste materials amount is big, wide, harm is serious, great environmental problem.Setting up vegetation itself in acid place promptly is to be imbued with a challenging difficult problem, and routine is reclaimed and disposed down that vegetation is difficult to survive or grows very poor.In most cases, the prevention and cure of pollution in the acid mine of China only limit to produce the back in acidity acid water are disposed.Take measures from the source that acidity produces in China, prevent to produce acid pollution, persistence ground ecology recovering is set up vegetation and still is in the Primary Study stage.
Summary of the invention
The purpose of this utility model just provides the compound insulation layer structure that a kind of acid waste-rock yard slope ecological is repaired, it can effectively improve the abominable land occupation condition of acid waste-rock yard side slope surface, improved plant growing condition, acid waste-rock yard side slope has been carried out ecological protection effectively.
The technical solution of the utility model is: the compound insulation layer structure that a kind of acid waste-rock yard slope ecological is repaired, comprise two-way geo-grid of plastics (2) and polyethylene drainage plate (5), also comprise the reclamation layer (4) between two-way geo-grid of described plastics (2) and the polyethylene drainage plate (5), the two-way geo-grid of described plastics (2), reclamation layer (4) and polyethylene drainage plate (5) by anchor pole (3) be fixed on domatic on.
Described reclamation layer comprises lime, plants loam and adhesive.
The thickness of described reclamation layer (4) is 2～3cm.
The compound insulation layer that is used for acid waste-rock yard slope ecological reparation that the utility model provides, on the one hand the reclamation layer has played the problem of the acid barren rock of good improvement in the early stage by the lime neutralization, and the late growing stage for plant provides good soil environment to a certain extent; On the other hand,, can form good soil layering structure by the buffer action of band drain, for seedling stage plant good growing space is provided, in addition, by the gap of anchor pole and band drain, for the plant growing of later stage resistance provides favourable passage.
Description of drawings
Fig. 1 is that acid waste-rock yard slope ecological is repaired the separation layer schematic cross-section.1 is side slope among the figure; 2 is the two-way geotechnological barriers of plastics; 3 is anchor pole; 4 are the reclamation layer; 5 is the polyethylene drainage plate.
The specific embodiment
Embodiment 1
As shown in Figure 1, the insulation layer structure that the utility model provides a kind of acid waste-rock yard slope ecological to repair, carry out following steps successively:
Reclamation layer 4: with lime, plant loam and adhesive evenly mixes, wherein, the lime and the consumption of planting loam are according to being 1: 10 by volume, and binder dosage calculates according to unit area to be sowed grass seeds by duster, and concrete consumption is 10g/m
2Wherein said adhesive is a kind of water-soluble organic class soil conditioner that a kind of high molecular weight polyacrylamide (PAM) is polymerized, and model is that gloomy A30 likes in France.
Lay the two-way geo-grid 2 of plastics on side slope 1, the equipment of sowing grass seeds by duster by specialty is ejected into the two-way geo-grid 2 of plastics with reclamation layer 4, makes the surface of the two-way geo-grid 2 of reclamation layer 4 plastic covering, and jet thickness is 2cm; After treating the initial set of reclamation layer, band drain 5 is laid on the reclamation layer 4, makes band drain 5 cover whole reclamation layer 4, and it is fixed on domatic 1 with anchor pole 3.
Embodiment 2
The reclamation layer: with lime, plant loam and adhesive evenly mixes, wherein, the lime and the consumption of planting loam are according to being 1: 15 by volume, and binder dosage calculates according to unit area to be sowed grass seeds by duster, and concrete consumption is 15g/m
2, the reclamation layer thickness of making is 3cm.Wherein said adhesive is a kind of water-soluble organic class soil conditioner that a kind of high molecular weight polyacrylamide (PAM) is polymerized, and model is that gloomy A30 likes in France.
Lay the two-way geo-grid 2 of plastics in side slope 1, the equipment of sowing grass seeds by duster by specialty is ejected into the two-way geo-grid 2 of plastics with reclamation layer 4, makes the surface of the two-way geo-grid 2 of reclamation layer 4 plastic covering, and jet thickness is 3cm; After treating the initial set of reclamation layer, band drain 5 is laid on the reclamation layer 4, makes band drain 5 cover whole reclamation layer 4, and it is fixed on domatic 1 with anchor pole 3.
The reclamation layer has played the problem of the acid barren rock of good improvement in the early stage by the lime neutralization, and the late growing stage for plant provides good soil environment to a certain extent; On the other hand,, can form good soil layering structure by the buffer action of band drain, for seedling stage plant good growing space is provided, in addition, by the gap of anchor pole and band drain, for the plant growing of later stage resistance provides favourable passage.
