Abstract

The present invention is greening technology for sheer soft slope. The technology of the present invention is superior to available technology and combines the technology of slope anchor bolt hung net and concrete spraying greening. The present invention can strengthen mechanical stability of soil, reduce the penetrating run-off, create excellent plant growth environment, reach excellent soil and water conservation effect, and result in high landscape effect and ecological effect.

Description

The greening technique of precipitous soft side slope

Technical field

The invention belongs to side slope water and soil conservation greening technique.

Background technology

In highway construction and Other Engineering construction; stay a large amount of precipitous soft side slopes through regular meeting; as some sand soil side slopes; meet softening high liquid limit soil side slope of water saturation and burning into sand or detritus soil side slope etc.; it is the difficult point of slope protection greening; the conventional method that solves this class problem is to adopt slabstone bank protection or concrete skeleton; hexagon hollow brick grass planting bank protection; but the skeleton of constructing on loose soil-slope still can form the crack; then form and subside; and said method work is heavy; progress is slow, is difficult to and the landscape effect that forms harmony on every side, has been not suitable for the needs of requirement of high-grade highway bank protection and urban environmental protection.

The precipitous soft greening side slope guard technology that the present invention proposes can overcome some shortcomings of above-mentioned greening technique, good soil and water conservation effect is arranged, and can bring better landscape effect and ecological effect, satisfy the needs of requirement of high-grade highway slope protection greening and modern city greening, reach comprehensive greening.

The present invention is according to water and soil conservation principle and plant growing rule, adopts domatic anchor pole linked network and spray concrete greening technique to combine, and reaches the mechanical stability of stablize soil body and domatic infiltration runoff, and creates good plant growing condition, realizes the purpose of inventing.

Summary of the invention:

Construction material and configuration:

1) anchor pole: long 2.0m, diameter 22mm.

2) gauze wire cloth: machine is compiled two knot hexagon galvanized steel wire nettings, size of mesh 8 * 12cm, and steel wire diameter 2.6mm, tensile strength is not less than 380Mpa.

3) grass seeds: utilize local landscape planting grass seeds of one's native land or root of bud dog: paspalum notatum: india lovegrass=3: 8: 5, add a spot of local undershrub and flowers and trees plant, spend as coronule etc.

4) pulping configuration: material mainly comprises sand loam, sawdust, husk, cake fertilizer, composite fertilizer, vegetation seed, cement or water etc.The every m3 of common on-the-spot pulping uses sand loam 810kg, grass-seed 3kg, each 60kg of sawdust and husk, cake fertilizer 120kg, composite fertilizer 10kg, the about 70～100kg of water, cement look the slope than getting 50～90kg, water-loss reducer 5～8kg, cement is used in winter construction more, the many waters of hot weather construction.

Construction technology:

1) remove the rock ballast, deposit etc. of surface dust, rubble, weeds and toe on domatic, domatic repairing is smooth.

2) anchor pole, linked network: with pneumatic drill punching on domatic, then the iron net unfolding is hung on domaticly, net plays the domatic about 5cm of distance with the brick pad, fixes anchor pole degree of depth 2.0m, spacing 2.0m * 2.0m again with anchor pole or holdfast.

3) sow grass seeds by duster: the pulping material is stirred, regulate the ph value, the about 10cm of jet thickness, note: sowing grass seeds by duster, it is domatic necessarily to cover fully.

4) cover: southern rainwater is many, sprays back covering nonwoven and prevents to wash away, and can cover straw screen or mat and preserve moisture northern dry season.

5) maintenance: watering keeps soil layer moistening, reduces the number of times that waters behind the Cheng Ping gradually.
