Description

A kind of green ecological river course slope protection structure
Technical field
The utility model relates to a kind of protective slope structure, particularly relates to a kind of green ecological river course slope protection structure.Belong to slope protection works field, be applicable to dyke, the side slope protection engineering in road, existing river course along the river.
Background technology
After ecological revetment refers to that excavation slope forms, utilize root system of plant the anchorage effect of Rock And Soil to be produced to the effect on protection, reinforcing side slope top layer, make it to meet to the stable requirement in side slope top layer, can recover again the bank protection mode of destroyed natural ecological environment, be a kind of bank protection effectively, solid slope means.The form of bank protection has direct protection and protection indirectly.Directly protection is that riverbank side slope is directly reinforced, to resist washing away and scour of current.The builds such as conventional jackstone, dry-laid rubble, mortar flag stone, gabion and fascine.Indirectly protection is applicable to the wider or protection larger section of length, riverbed, can build groynes, longitudinal dike and lattice dam etc., and current are chosen from riverbank.
At present, the ecological revetment type of domestic direct protection mainly contains vegetation slope pavement, the solid soil species phytyl bank protection of earth working material, vegetation type eco-concrete slope-protecting vegetation, the solid native phytyl of precast concrete block body, Ecotypic Stone Mesh-box bank protection etc.
Vegetation slope pavement is that the solid native plant of the flourishing root system of employing carries out the solid soil of bank protection, both can reach solid soil guarantor husky, prevents erosion, and can meet again the needs of ecological environment, can also carry out view reward.But vegetation slope pavement is due to maintenance management difficulty in early stage, and new turfing, plant are subject to various natural calamities, often do not reach satisfied side slope protection effect, and cause domatic coombe, the table soil side slope phenomenon such as sliding that runs off, collapses.
The principal mode of the solid soil plantation of earth working material bank protection is geotechnological gauze pad grass planting bank protection, belongs to national new high-tech product.Geotechnique's gauze pad quality is loose, pliable and tough; leaving 90% space can filling soil, grit and microlith; root system of plant can be through therebetween; comfortable, neat, balanced growth; turf after growing up to combines gauze pad, turf, earth surfaces securely, has formed the firm green composite protection layer of one deck.But present geotechnological gauze pad great majority be take thermoplastic resin as raw material, after ageing of plastics, easily in soil, easily form secondary pollution, when river water level is higher, be prone to stability problem in addition.
Vegetation type eco-concrete slope-protecting vegetation is comprised of porous concrete, water-keeping material, slow release fertilizer and topsoil.Porous concrete, by coarse aggregate, cement, appropriate thin blending composition, is the skeleton of vegetation type eco-concrete, has compared with highly-breathable.Water-keeping material be take organic water-loss reducer as main, and mixes inorganic water-loss reducer and mix use, can be plant essential moisture is provided.Topsoil is layed in cellular concrete surface.But the type bank protection is through naturally changing after a while, and the alkalescence of eco-concrete can make plant withered.Because itself is still for concrete rigid structure cannot adapt to the destruction that any distortion causes, when building, reserved again a lot of holes and cannot guarantee integrally-built intensity, and this structure is not considered the waterpower destruction problem of the bank protection soil body and the global stability problem of side slope.
In sum, although existing ecological revetment has been obtained good consolidation effect under suitable engineering specifications, remain the problems such as afforestation effect is not good enough, stability is not enough.Given this, according to the actual needs of current engineering and technical condition, need badly a kind of whole structural stability of invention good, there is certain ecological afforestation function, can prevent the river course slope protection structure that side slope generation waterpower is destroyed simultaneously.
Summary of the invention
The purpose of this utility model is to provide that a kind of energy is permeable, ventilative, the ecological revetment structure of protection against erosion, can meet the level of protection of river course system, be beneficial to the green ecological river course slope protection structure of recovering river course system ecology balance again.
A river course slope protection structure, is characterized in that comprising spats structure and bank protection surface layer, and described spats structure comprises erosion control piece stone and the stake arranging along side slope toe; Described bank protection surface layer comprises that along the direction perpendicular to bank protection geotechnological water proof material layer, permeable boulder bed, anti-filter earth working material layer, Earthworking reinforced bar material layer, eco-concrete are every structure, green soil layer from bottom to top successively; The crushed gravel layer of bottom, bank protection Po Ding gutter is connected with permeable boulder bed; Geotechnique's water proof material layer extends to bottom, gutter.
Described stake is uniformly-spaced evenly arranged along Channel slope direction, and pile body stretches into river bottom soiol 800 ~ 1500mm, and stake is risen in erosion control piece stone 100 ~ 300mm.
Described erosion control piece stone outer wrapping Earthworking reinforced bar material or reinforcing cage, Earthworking reinforced bar material or reinforcing cage are connected with pine stake colligation.
Described eco-concrete can rounded or polygon every structure, can be cast in situs or adopts concrete precast element assembled, fills green soil in it.
Described permeable boulder bed top is connected with the crushed gravel layer of bottom, gutter, top, and bottom is connected with erosion control piece stone.
The utlity model has following feature and beneficial effect:
(1) anti-filter non-woven geotextile, Earthworking reinforced bar material, eco-concrete are used in combination every structure, can make river course slope protection have the advantages such as good integrity, stability are strong, long service life.
(2) setting of permeable boulder bed, geotechnological water proof material layer both can be got rid of side slope top water body fast, can infiltrate in the soil body of bottom by anti-water-stop body again.
(3) root system of plant and eco-concrete can maintain domatic soil body stability every structure, can prevent that the domatic soil body runs off, and its later stage maintenance cost is low.
(4) erosion control piece stone and pine stake are set at toe position, can play ballast effect, be conducive to monolithic stability and the local stability of slope body.
