Description

Suitable for the gabion subgrade protection structure of karst area

Technical field

It the utility model is related to technical field of road construction, and in particular to a kind of gabion roadbed suitable for karst area is prevented Protection structure.

Background technology

Karst is karst (KARST), is that water is carried out with chemistry to solublerock (carbonate rock, gypsum, rock salt etc.) Based on corrosion, the geologic process supplemented by the mechanism such as the erosion of flowing water, latent erosion and avalanche, and produced by these effects The general name of raw phenomenon.The landforms as caused by karsitification, claim karst landform (karst features).It is fast due to engineering activity Speed development, the frequency of karst ground subsidence, intensity and harmfulness are also increasing, these generations collapsed, none not with work Journey action attacks karst area original poised state is relevant.Karst ground subsidence has become current karst area roadbed and built If face extremely widespread, but insoluble engineering geological problems, it is therefore necessary to the measure for prevention of taking the initiative, wherein The dykes and dams of one of gabion box are assembled with gabion net cage, for protection road of keeping the flood in check, prevent side slope slump, soil erosion from destroying Ecological environment is a kind of mean of defense being often used, and traditional gabion box is only a cage type structure, for containing Stone, it is more difficult green plants to be planted on gabion bank protection.

Utility model content

To solve above technical problem, the utility model provides a kind of gabion subgrade protection knot suitable for karst area Structure.

Technical scheme is as follows：A kind of gabion subgrade protection structure suitable for karst area, its key are：Including along the river Roadbed, the side slope of the roadbed along river are provided with greening gabion, and the greening gabion is in successively from the bottom of side slope to top-direction Stepped stacking；

The greening gabion includes gabion net cage and greening frame, and the gabion net cage is interior filled with protection stone, the stone The case mouth of cage net cage is provided with net cage cover plate, and the net cage cover plate is provided with the greening frame, and the greening inframe is filled with greening Soil, the net cage cover plate are provided with permeable hole, and the permeable hole connects the greening frame with gabion net cage.

The dykes and dams of one of gabion box are assembled with side of the gabion along river course using above-mentioned technical proposal, are protected for keeping the flood in check Berm road, gabion layering are stacked, and effectively solve ecology caused by landslide, soil erosion, water pollution etc. in state protection zone Destruction problem, compared with traditional mortar flag stone and concrete protect, gabion protective slope structure is with more " ecological ", " landscape " to base Plinth requires low many advantages, and its structure type is more flexible, easily solves the problems, such as engineering raw material, economical, can be effective Ground reduces the construction costs of mountain area supporting construction, and the greening inframe of gabion can plant green plants, not only attractive in appearance to enter One step prevents the soil erosion of earth's surface.

Further, welded between the greening gabion of adjacent layer, at interval of two layers of the greening stone in the roadbed along river Cage is respectively equipped with reinforcing anchor pole, and the outermost greening gabion fixes company with the corresponding reinforcing anchor pole in the side slope Connect.It is more firm using the fixation of this design gabion using the design.

It is reinforced gabion and zinc-plated gabion that above-mentioned greening gabion, which includes, and the greening gabion of the bottom is in the side slope Reinforced gabion, the zinc-plated gabion is successively stacked with the reinforced gabion.It is good using the zinc-plated gabion associativity of the design, can be more preferable Ground adapts to hillside, and the shape of seashore and dyke, reinforced gabion construction is fast, and cost is low, with reference to and protection gabion so a little both It can fully meet that construction requirement is again cost-effective.

Above-mentioned gabion box case includes outer case, is arranged with least one internal box in the outer case, the outer case and interior Casing is set in " returning " shape, and the protection stone is separately filled with the outer case and each internal box.Using this scheme side Just successively filling protection stone.

The block footpath of above-mentioned protection stone is gradually reduced from the outer case toward the direction of the internal box of innermost layer, the outer container The block footpath of internal protection stone is more than the mesh aperture of the outer case.Using this scheme by successively loading different masses footpath Stone, small stone is located among gabion while the stone in all kinds of pieces of footpaths is made full use of, filling more consolidation, firmly.

Above-mentioned green soil includes undermost boulder bed, is equipped with fine sand layer on the boulder bed successively from the bottom up and sticks Soil layer.Using the root of this scheme earlier plant substantially in clay layer, with its root of the constantly growth of plant can be gradual To submucosa growth, so as to which the larger protection stone in lower floor's block footpath be fixed, such longer period of time gabion net cage gets rusty corruption Erosion rear protecting stone, which can be still fixed, plays protective action.

The framework of above-mentioned greening frame is provided with air-vent, and the aperture of the air-vent is less than the aperture of the permeable hole.Adopt Plant root air permeable effect with this design plantation is good, and growth is more preferable.

Green plant protection network is equipped with the frame mouth of above-mentioned greening frame.Can early stage plantation using the green plant protection network of this design Play a part of windproof fixation to plant.

The top of above-mentioned outer case is respectively equipped with suspension ring at its corner.Gabion net cage is carried using this design is convenient.

Above-mentioned net cage cover plate is installed in rotation on the case mouth of the outer case by rotating shaft, the bottom of the greening frame It is fixedly mounted on the upper surface of the net cage cover plate.This design whole device is used as monoblock type, rotating opening net cage cover plate Protection stone can be filled.

Beneficial effect：It is to assemble one of gabion box with side of the gabion along river course using the beneficial effects of the utility model Dykes and dams, for protection road of keeping the flood in check, gabion layering is stacked, and effectively solves landslide, soil erosion, water in state protection zone Ecological disruption problem caused by matter pollution etc., compared with traditional mortar flag stone and concrete protect, gabion protective slope structure is with more " raw The many advantages such as state property ", " landscape " be low to fundamental importance, its structure type is more flexible, easily solves asking for engineering raw material Topic, it is economical, the construction costs of mountain area supporting construction can be effectively reduced, and the greening inframe of gabion can plant green plant Thing, the not only soil erosion attractive in appearance that can also further prevent earth's surface.
