On the basis of technique scheme, in described S6, soil moved in improve the original is evenly sowed grass seeds by duster to being covered with the domatic of galvanized wire mesh by removed-earth jet sowing machine, is divided into from top to bottom and sows grass seeds by duster for twice, and the 5cm that sows grass seeds by duster for the first time is thick, after soil stabilization of receiving guests, again sows grass seeds by duster to design thickness.
On the basis of technique scheme, in described S7, vegetable seeds chooses Bermuda grass, Festuca Arundinacea, horse sour jujube, wild golden aster mix.
On the basis of technique scheme, in described S7, the non-woven fabrics of covering is 30g/m2, and described maintenance comprises water spray, reseed, weed a garden and the control of disease and pest.
Beneficial effect of the present invention is: rock slope ecological protection method, by soil moved in improve the original of sowing grass seeds by duster, vegetable seeds, realizes the vegetal cover of rock slope, avoids producing domatic loosening phenomenon of being scattered with stone, eliminates safe hidden trouble, is conducive to the maintenance of ecological environment.
Accompanying drawing explanation
Fig. 1 is the flow chart of rock slope ecological protection method of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As shown in Figure 1, rock slope ecological protection method of the present invention, comprises following concrete steps:
S1. mucking side slope is domatic, is specially: except foreign material and the loosening sillar of the rock slope scope of operation, repairs, make it curved to the corner angle on domatic corner and top, slope, as far as possible that the scope of operation is smooth, is beneficial to subsequent step.For smooth scar, offer a transverse groove every certain altitude thereon, offer altogether many transverse grooves, to increase the roughness of the scope of operation, and then increase adhesive power.
S2. according to the drawing requirement designed in advance, the domatic surveying setting-out in rock slope is arranged anchor hole position, and plug anchor pole and grouting and reinforcing in each anchor hole.Described anchor pole adopts diameter to be the indented bars of 18cm, and many anchor poles are that array is arranged.Meanwhile, be drilled with multiple hole at scar, in each hole, insert an aqueduct.
S3. spray one deck cement mortar, treat that it solidifies.Before injection, first with floating dust, the chip of high pressure water washing by spray scar, when scar meets the easy deliquescence of the water capacity, argillization, blow off scar with high-pressure blast.
S4. on the cement sand bed solidified, lay steel mesh reinforcement, and steel mesh reinforcement hangs on described anchor pole, pneumatically placed concrete solidifies again, and described anchor pole exposes layer of concrete.Preferably, cement mortar layer thickness is 4 ~ 5cm, and steel mesh reinforcement distance cement sand bed surface is more than or equal to 2cm, ensures slope stability, avoids loosening.The layer of concrete again sprayed is 5 ~ 10cm, and blocks the mouth of pipe of aqueduct, but layer of concrete has gap, does not shut aqueduct, aqueduct can between rock and layer of concrete water guide.
S5. outside the layer of concrete solidified, often row anchor pole and often all tired bundle of row anchor pole fix a batten, many battens form square frames.Preferably, batten is China fir, and the rectangle batten of processing growth 500cm, wide 5cm, high 10cm, is tied up by iron wire and be fixed on anchor pole, form vertical resistance, prevent planting matrix landing on concrete.Then on the square frame of batten formation, lay galvanized wire mesh, preferably, galvanized wire mesh is regular hexagon, machine volume two kink individual layer No. 14 galvanized wire mesh, and the mesh length of side is less than or equal to 5cm.
S6. first configure soil moved in improve the original, soil moved in improve the original primarily of greening backing, fiber, plant loam and mix by a certain percentage, preferably, mix according to volume ratio 1:2:2.Wherein, greening backing mainly includes machine matter, soil conditioner, can carry out code test according to actual features, selected match ratio.Planting loam selects the engineering original ground surface soil in ground or neighbouring farmland soil to carry out pulverizing 8mm sieve, water content≤20%, air-dry sieve after plant loam and should take waterproof measure.Fiber mainly comprises stalk, branch, is ground into 10 ~ 15mm long, moisturely should take waterproof measure, Han Shui Liang≤20%.
Then, by removed-earth jet sowing machine by alien earth sparging to being covered with the domatic of galvanized wire mesh, covering with new soil galvanized wire mesh.Concrete, selecting professional removed-earth jet sowing machine, evenly being sowed grass seeds by duster by soil moved in improve the original to being covered with the domatic of galvanized wire mesh, the 5cm that sows grass seeds by duster for the first time is thick, after soil stabilization of receiving guests (10 ~ 20min), again sows grass seeds by duster to design thickness.Alien earth sparging should adopt the thickness of sowing grass seeds by duster of about 10 ~ 12cm, and section thickness of sowing grass seeds by duster in broken in lithology, hard slope suitably can adjust according to actual conditions.
S7. to sow grass seeds by duster vegetable seeds with spray seeder, vegetable seeds chooses Bermuda grass, Festuca Arundinacea, horse sour jujube, wild golden aster mix.After having sowed grass seeds by duster, good with non-textile mulch, be preferably the non-textile mulch of 30g/m2, then safeguard, safeguard to comprise and spray water moderately and at the right moment, reseed, weed a garden and the control of disease and pest, until throw off non-woven fabrics when seedling plants grows to 5 ~ 6cm or 2 ~ 3 leaf, to ensure the normal growth of seedling.
The present invention is not limited to above-mentioned embodiment, and for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications are also considered as within protection scope of the present invention.The content be not described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
