Background technique
The natural causes such as the construction (such as railway, highway, urban rail) of infrastructure, mining and mud-rock flow, earthquake
Under the influence of, primary soil disturbance and terrestrial erosion certainly will be aggravated, accelerate natural ecosystems and degenerate and landscape fragmentation speed, from
And generate a large amount of secondary exposed rock side slopes.Rain Garden is applied in slope ecological slope protection, can be constructed various
It is suitble to the matrix of plant growth, to establish the ecosystem of a benign cycle for rock slope foot, slope surface.This rainwater side slope
Facade landscape effect is good, can rapid Cover, have sustainability, more can effectively solve China and face improvement bare rock at present
This great difficult problem of side slope.
Utility model content
The rainwater side slope based on mine reclamation that the technical problem to be solved by the present invention is to provide a kind of, by Rain Garden
It applies at rock slope slope foot, constructs and be suitble to rock slope vegetation growth environment.
The utility model is that technical solution in this way is realized, a kind of rainwater side slope based on mine reclamation includes building
Stone water storage well, soakaway trench, Rain Garden, it is characterised in that: setting masonry block stores in the Rain Garden at rock slope slope foot
Well and soakaway trench, which facilitate, to be collected rainwater and is irrigated for root system of plant;The masonry block water storage well is piled up with rock block
At a round well, for rain during collect and store rainwater, well lid is concrete structure, and is porous receipts well
Lid, is mainly used to collect rainwater, takes root for the quick rainwater collected at rock slope, conducive to plant, masonry block water storage well abuts
Rock slope setting, is arranged a masonry block water storage well according to the length of Rain Garden at a certain distance.
The beneficial effects of the utility model are: both collecting, storing, utilizing rainwater, moreover it is possible to gather materials on the spot, make full use of rock
The stone of side slope plays positive effect to the vegetation protection and recovery of rock slope.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples:
As shown in Figure 1, the utility model includes masonry block water storage well 1, soakaway trench 2 and Rain Garden 3, it is characterised in that:
Setting masonry block water storage well 1 and soakaway trench 2, which facilitate, in Rain Garden 3 at rock slope slope foot collects rainwater and is root system of plant
Moisture is provided.
Masonry block water storage well 1 is that rock block piles up the round well of to be formed one, for collecting during raining and storing rainwater.Well
Lid is concrete structure, and is porous receipts well cover, is mainly used to collect rainwater.Quickly to collect the rain at rock slope
It water and is taken root conducive to the plant in Rain Garden 3, masonry block water storage well is arranged against rock slope, according to Rain Garden length
One masonry block water storage well is set at a certain distance.
Soakaway trench 2 is PVC plastic pipe, is arranged in the layer of sand of Rain Garden, and penetrates through masonry block water storage well and seep to soil layer
Water.2 surrounding of soakaway trench wraps up geotextiles, prevents sand from blocking soakaway trench.
The soil constituent of Rain Garden 3 is from bottom to top followed successively by hand-stuff layer 4, layer of sand 5, planting soil layer 6.Hand-stuff
Layer 4 is ratchel or cobblestone, and planting soil layer 6 is local sand, and sand content is 60%-85% in main component,
Facilitate rainwater infiltration, guarantees gas permeability.
Marsonary retaining wall 7 is located at the side of Rain Garden 3, is piled up with rock block, and is higher by Rain Garden kind
Native certain distance is planted in favor of collecting rainwater.
Rock slope 8 is located at the other side of Rain Garden 3, is had in construction by the sundries in slope surface and loosens rock
Remove, cleaning is uneven and loose ground so that treated slope surface tilt it is consistent, smooth, without big stone it is prominent or its
He exists sundries, guarantees that construction surface is smooth.It is conducive to composite earthwork cloth in this way to combine closely with slope surface, prevents rainwater from passing through composite earth
Gap between work cloth and rock slope 8 flows away.
When being laid with the soil of Rain Garden 3, fundamental aspect will be cleaned out and smooth, cannot locally be had rough existing
As can choose the lesser sandy soil of partial size and carry out levelling and tamp, be then laid with composite earthwork cloth, be laid with always to cemented rock
Retaining wall top and rock slope planting soil intersection.
Selection absorption class tendril --- the Boston ivy of plant 9 in Rain Garden 3, with 3 meters of one plant of plantations.
The above is only the preferred embodiment of the utility model, not does any type of limitation to the utility model,
Any content without departing from technical solution of the present invention, it is made to the above embodiment any according to the technical essence of the utility model
Simple modification, equivalent change and modification belongs to the range of technical solutions of the utility model.
