Description
Technical field
The utility model is related to the ecological slope protection device technical field based on water plant volume with geotechnological coconut palm net, specially one
Plant the ecological slope protection device based on water plant volume with geotechnological coconut palm net.
Background technology
Traditional slope protection works is main building materials typically with hard materials such as cement, building stones, concrete, in design with power
Angle goes to think deeply stability of slope, is preferential generally all with safety, economy, have ignored restoration of the ecosystem, makes the ecological work(of side slope
Can recover more difficult.Meanwhile, the implementation of traditional bank engineering construction is also tended to occurring in that substantial amounts of construction and excavation,
Cause substantial amounts of exposed soil-slope and rock slope, change original landforms and stress state so that some side slopes it is steady
Qualitative to there occurs change, original ecosystem is destroyed, and may further cause even more serious soil erosion and environment
Disruption of ecological balance problem.
The function in river course has been not only " rush down flood, water drainage, retaining, draw clear, shipping ", but also including " landscape, trip
Trip, ecological and concord to surrounding enviroment " etc..Requirement more and more higher of the people to water environment, not only needs and ring around
The River Landscape that border is mutually coordinated, and need the luxuriant natural, ecological landscape of river so clear that you can see the bottom, fishes and shrimps migration, pasture and water.In order to
Ensure stabilization and the protecting ecology bad border of side slope, more ecological revetment types start gradually to be applied to river and lake shore protection.
Main Ecological Slope form has much at present, such as direct grass planting skin, grass seeds of sowing grass seeds by duster, extension Three-Dimensional Network Seeding, thick photoresist grass planting,
Plant biological bag etc..Either that method has some shortcomings：As direct grass planting skin intricate operation, time are long, and transplant grass
Skin freight volume is big, and scour resistance is weak after transplanting, fails to slow down rain infiltration and erosion slopes within a very long time；Spray
Broadcast that grass seeds is cheap, easy construction, but side slope surface does not possess erosion resistibility, and grass seeds is influenceed by rainwater wind,
Survival rate is not high, DeGrain；Thick photoresist grass planting, extension Three-Dimensional Network Seeding, plant biological bag are all that grass seeds etc. is existed using carrier
Afforested in side slope, play and preferably consolidate domatic effect, but it is relatively costly, and the plastic products materials such as three dimensional network are to ecology
Environment has certain destruction, and plant biological bag bank protection rainwater is domatic from the gap seepage scour between plant biological bag, domatic anti-impact brushing effects
It is unobvious.In a word, current ecological revetment mode respectively has advantage and disadvantage, and side slope protection has utilization, and achieves good
Effect.But not yet there is one kind to possess that cheap, erosion resistibility is strong, construction is simple, impermeability is strong, to zero environmental etc.
The method of various advantages.
