Abstract
The invention provides a high and steep slope vegetation recovery structure. The surface layer of a high and steep slope body is covered with a growth substrate; a reinforced mesh is positioned in the growth substrate; water-blocking grooves are horizontally distributed in the growth substrate; a seed germination substrate is longitudinally embedded in a strip shape into the growth substrate; seed germination holes are distributed in microporous thin films according to the position of the seed germination substrate; the surfaces of the growth substrate and the seed germination substrate are covered with the microporous thin films in a fitted manner; the microporous thin films are clung to the bottoms of the water-blocking grooves at the water-blocking grooves. The slope substrate of the recovery structure is stable; soil or broken stones on the slope surface are effectively prevented from sliding off; the recovery structure is light in self weight, thereby facilitating the fixation of a greening substrate, increasing the germination rate of seeds and increasing the cover degree of vegetation; the water-blocking grooves are capable of prolonging the retaining time of the moisture from natural rainfall or manual watering on the microporous thin films to further enable the moisture to penetrate the growth substrate, thereby avoiding the runoff loss under the high and steep slope condition and the erosion of the runoff on the growth substrate or the seed germination substrate.
Description
Technical field
The invention belongs to high gradient slope revegetation Treatment process field, and in particular to a kind of recovery of high gradient slope vegetation
Structure.
Background technology
China's geographical configuration is complicated, and high gradient slope has a very wide distribution, and it has the characteristics of gradient is larger, slope is high, because
This, its own water conservation, fertilizer conservation and solid soil ability are poor, and for protecting slope vegetation or resuming work, difficulty is big, the cycle
Long, recovery effects are also undesirable.
At present for high gradient slope vegetation control measures mainly have following several：
（1）Thick photoresist greening structure：It is applied to soil-slope, and slope gradient is not suddenly in 1:1 middle air slaking or weak
Air slaking rock side slope and domatic broken, the poor loose crumb stone of vegetation growth and containing the instable slope of larger rubble.
But when the gradient is steeper, its defect will be apparent upon, such as cannot overcome the weight of the high steep and soil itself of side slope, it is impossible to resist
Prolonged heavy rain washes away and is exposed to the sun with burning sun, ultimately forms that rill erosion, sheetflood are even domatic to collapse, so as to cause domatic secondary damage
Wound, is highly detrimental to greening backing and fixes, and is easily washed away by heavy rain, and fixing of soil and conservation of water ability is poor.
（2）Plant cover concrete is sowed grass seeds by duster protective slope structure：It often takes building stones or concrete masonry units retaining wall and mask, or
Fully closed protection is carried out using the method side slope of spray anchor, this traditional side slope protection is the rigidity for repelling green plantss
Protection, although do so can prevent the disasters such as the serious erosion of soil and water that slope instability brings and landslide, mud-rock flow, also brings
Serious environmental problem, such as visual pollution, disruption of ecological balance, and also to be restricted with domatic height by domatic angle, no
Can be exhaustive, the contact for having completely cut off vegetation and natural soil and rock using the structure sowed grass seeds by duster is added, cause seed germination rate
Lowly, vegetation cover degree is little, and root system of plant is unstable, is susceptible to a series of problems such as lodging.
The content of the invention
For above-mentioned deficiency, the present invention provides a kind of recovery structure of high gradient slope vegetation, and the domatic substrate of the structure is stablized,
The domatic of any gradient can be flexibly applied to, and prolonged heavy rain can be resisted and washed away and be exposed to the sun with burning sun, it is solid beneficial to greening backing
Fixed, solid native, solid fertile, water holding capacity is good, adds its deadweight less, it is ensured that vegetation and natural soil or rock are fully contacted,
So as to improve seed germination rate, increase the cover degree of vegetation, improve domatic greening speed.
The present invention is realized by such technical scheme：

Can effectively prevent domatic soil or rubble from sliding, even if being washed away by heavy rain length day, it is also possible to prevent it is domatic collapse, recovery knot
Structure easy construction, deadweight is relatively light, reduces domatic load, is not affected by geological conditions, can be flexibly applied to the domatic of any gradient,
It can resist prolonged heavy rain and wash away and be exposed to the sun with burning sun, fix beneficial to greening backing, special microporous membrane can improve it is solid soil,
Gu fertilizer and water holding capacity, effectively suppress the evaporation of moisture, water management program is reduced, lift the water utilization effect of high gradient slope
Rate, the perforate on thin film makes the breathability of growth substrate just right, and then improves seed germination rate, along with the structure is also protected
Being fully contacted for vegetation and natural soil or rock is demonstrate,proved, so as to further improve seed germination rate, has increased the cover degree of vegetation, planted
Thing can fast-germination, Cheng Ping, improve domatic greening speed；It is further to block water groove to make natural rainfall or manually apply
The moisture of water extended residence time on microporous membrane, further makes moisture be fully infiltrated in growth substrate, it is to avoid on high steep side
Runoff loss and runoff under the conditions of slope sprouts the erosion of substrate to growth substrate or seed, final effectively quickly to realize high steep side
The greening and protection on slope.
