Abstract

The utility model relates to a slag vegetation recovery structure, aiming at solving the problems that the vegetation of the surface of the slag side slope is difficult to be recovered and the later effect is not stable after the vegetation is reconstructed so as to reduce the later maintenance and management work. The technical proposal is that: the utility model is provided with slag covered by casing soil, and vegetation is planted on the casing soil. The utility model is characterized in that a grid framework structure is built on the slag, and the bottom of the grid framework structure is buried in the slag. The utility model can be applied to the highway project, the railway project, the water conservancy and hydropower project and industrial and civil buildings and other large-scale construction projects, all of which produce waste slag side slopes and the slipping slag side slopes where the vegetations of the side slopes are needed to be recovered.

Description

Slag body revegetation structure

Technical field

The utility model relates to a kind of slag body revegetation structure.The waste body side slope that is applicable to highway engineering, railway engineering, Hydraulic and Hydro-Power Engineering, industry and civil buildings and other large-scale construction projects and produces, slide slag body side slope etc. need be carried out the situation of slope vegetation restoration.

Background technology

Current stage is carried out the technology that revegetation often adopts earthing to scatter seeds on the slag body, direct earthing on domatic, carry out seed broadcasting or plant transplanting etc. then, these measures exist generally water and soil loss greatly, anti-washing away not, the shortcoming that anaphase effect is bad.Fast because of water and soil loss speed, often form many coombes that scale does not wait on domatic, also can cause satisfying water in the slag body and cause problem such as sloping body unstability.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of slag body revegetation structure is provided, and scheming to solve the revegetation difficulty of these slag body side slope faces, and its anaphase effect problem of unstable after the revegetation ecology, reduce work such as later maintenance and management.

The technical scheme that the utility model adopted is: slag body revegetation structure, have the slag body, and cover overburden layer on it, plant vegetable layer on the overburden layer, it is characterized in that making up on the described slag body grid frame structure, its bottom is imbedded in the slag body.

Described grid frame structure adopts cemented rock or placed rockfill or armored concrete or plain concrete construction; And the grid frame structure forms rhombus or multiple arch shape or square or bow member shape.

Described overburden layer is a meta structure or diadactic structure.

Described overburden layer thickness exposes height greater than the grid frame structure; Or equal the grid frame structure expose the height; Or less than the grid frame structure expose the height.

The beneficial effects of the utility model are: the utility model makes up the grid frame structure on the slag body, slag surface side slope has been carried out stable processing and marked off the small units of earthing, cover one deck earthing structure then, pass through the embedded structure of grid frame structure simultaneously, can be so that grid frame structural system and slag body effectively merge, form integratedly, improve globality, abrasion resistance greatly.Structure choice by overburden layer, can prevent water loss, and then guarantee the necessary moisture of plant growing, thereby keep the ecosphere growth result on the side slope face, meanwhile greatly reduce the cost of later stage maintenance management, thoroughly solved the revegetation problem of slag body side slope face.

Embodiment

As shown in Figure 1 and Figure 2, present embodiment adopts cemented rock or measures such as placed rockfill or reinforced concrete structure or plain concrete construction on slag body 1 surface, make up grid frame structure 4, as Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, its shape can be geometries such as rhombus, multiple arch shape, square, bow member shape.Slag body layer is imbedded in grid frame structure 4 bottoms, and length of embedment can comprehensively be selected according to the thickness of slag body 1, the lumpiness and the sloping body degree of stability of slag.On the described slag body 1, be coated with overburden layer 2 in the skeleton grid, overburden layer 2 structures also have a meta structure or diadactic structure, as shown in Figure 7, and to the soil property and the bad slag concrete conditions in the establishment of a specific crime of water permeability of permeance property difference, adopt the monobasic soil layer construction, promptly directly cover one deck plantation soil layer 2-1 in the slag surface; As shown in Figure 8, soil property and the water permeability good slag concrete conditions in the establishment of a specific crime good to permeance property adopt the binary soil layer construction, at first are covered with certain thickness viscous soil horizon 2-2 in the slag surface, cover plantation soil layer 2-1 then thereon.The thickness of overburden layer 2 is as the criterion to satisfy the plant growing needs, can according to actual conditions can select greater than, be equal to or less than grid frame structure 4 expose the height three kinds (as Fig. 9, Figure 10, shown in Figure 11).Plant vegetable layer 3 by the plantation means on the overburden layer 2.

After above-mentioned implementation of processes, can on slag body side slope face, carry out revegetation rapidly.Grid frame structure 4 has been carried out stable processing with slag body 1 surperficial side slope and has been marked off the small units of earthing, the form of imbedding of grid frame structure 4 can make surperficial vegetable layer 3 well combine together with slag body layer, further stablize domatic and stable overburden layer 2, the effectively interior water loss of controlling plant grown layer of the structure choice of overburden layer 2, kept the necessary moisture condition of vegetation growth, after plant growing is vigorous can with overburden layer 2, grid frame structure 4 comprehensively plays effective protective action of slag surface and rapid afforestation effect, stable and the good water retention property on top layer makes the revegetation later stage maintenance work on the slag body side slope face reduce greatly, thereby greatly reduces the cost of later stage maintenance management.
