Abstract

The utility model discloses a kind of rock slope timber solid earth greening alive structure, comprise cutting hole, timber, planting bag alive.Stable rock slope digs cutting hole, inner filling Nutrition Soil; There is otch the side of timber alive, can insert in cutting hole, and fix with fence rope; Planting bag overlays above fence successively, and the sack staple that is connected connects into entirety; In the hole that planting bag and rock slope are formed, fill Nutrition Soil, soil layer surface coverage plastic film.The timber alive that the utility model utilizes cuttage plant of one's native land to be made into, when after active branch germinating growth, itself has landscape effect, instead of original stone, cement prefab, construct permanent software side slope, greening vegetation speed is fast, and structure is simple, speed of application is fast, significantly can reduce engineering cost.

Description

Rock slope timber greening structure alive

Technical field

The utility model belongs to greening side slope field, particularly relates to a kind of rock slope timber solid earth greening alive structure.

Background technology

In the construction processes such as highway, railway, mine, water conservancy; much precipitous rock wall or soft side slope etc. are left in frequent meeting after engineering; the regeneration of exposed section vegetation and recovery is made to be subject to extreme influence; even cause serious water and soil loss, finally cause the highway after building up, railway, mine, water conservancy slope collapse.

Greening side slope is a kind of emerging ecological revetment mode effectively protecting bare slope, and it combines with traditional project post-evaluation, effectively can realize domatic ecological vegetation and recover.Rock side-slope generally belongs to high gradient slope, without the condition of plant growth, needs soil moved in improve the original during greening.Rock is completely exposed, moisture and nutrient condition poor, plant be difficult to growth.

The greening method that rocky slope outside Current Domestic is conventional has the method such as alien earth sparging method, tape planting (basin, bag) method, three-dimensional grid method, concrete frame lattice beam method, thick layer base material spraying greening vegetation, plant cover concrete greening, fish scale pit excavation technology, planting groove technique, vine greening.But these method great majority all face cost intensive, the fixing difficulty of base material, the problems such as vegetation vitality is not strong, and vegetation moisture, nutrient supply are not enough, meanwhile, a large amount of exposed rocks and concrete vision, the non-constant of landscape effect.

Summary of the invention

In order to overcome deficiency of the prior art, the utility model proposes a kind of rock slope timber solid earth greening alive structure, the timber alive of cuttage plant constitution of one's native land itself is utilized to have landscape function, can also soil and slope protection, simultaneously along with the growth of wooden branch of living, the entirety realizing rock slope together with surrounding plants covers greening, solves the problem that rock slope greening is difficult.

The technical solution adopted in the utility model is: on stable rock slope, dig cutting hole, inner filling Nutrition Soil; There is otch the side of timber alive, can insert in cutting hole, and fix with fence rope; Planting bag overlays above fence successively, and the sack staple that is connected connects into entirety; In the hole that planting bag and rock slope are formed, fill Nutrition Soil, soil layer surface coverage plastic film.

Described cutting hole, on stable rock slope with horizontal spacing 2 ~ 3m, vertical clearance 1.5 ~ 2.5m be blossom type distribution, upward, aperture 10 ~ 20cm, hole depth is not less than 30cm in aperture.

Described timber alive, formed by the activated cuttage plants shoots of one's native land of tool and the reinforcing bar mixing manufacture being no less than 15%, by active branch otch towards side, connect with rope and weave into faggot, active branch quantity proportion is no less than 40%, between adjacent timber alive, make fence with plants shoots and the reinforcing bar being no less than 20%, with rope, work timber is fixedly connected with fence.

Further, described reinforcing bar should choose diameter 1 ~ 2cm, is mainly used to the bearing capacity increasing timber alive and fence.

Further, described active branch should choose the indigenous plant branch of diameter 2 ~ 3cm as locust tree, weeping willow, the bark of eucommia, Chinese white poplar, removing leaf, being cut into length with scissors is 60cm ~ 100cm, by the branch alignment sheared, 20 ~ 40 are bundled into a branch of, in order to prevent wicker dry before cuttage, should be immersed in water or being contained in keeping inside plastic sack.

Described planting bag, the geotextiles be made up of macromolecular material is made, and central filler has the mixture of soil, climbing plants seed, water-loss reducer, fertilizer, overlays successively above fence, and the sack staple that is connected connects into entirety.

Further, described Nutrition Soil, is mixed by the multiple material such as fine earth, modifying agent, binding agent, composite fertilizer, water-loss reducer, vegetable fiber, repeatedly granule agent, increases soil fertility, for plant growth creates good soil environment.

The beneficial effects of the utility model are: utilize the timber alive that cuttage plant of one's native land is made into, and when after active branch germinating growth, itself has landscape effect, together with surrounding plants, form graceful view, naturally coordinate; Space reclaimed soil between planting bag and rock slope, planting bag coordinates with backfill soil, add soil thickness, nutrient needed for enough vegetation and moisture can be provided, and unnecessary rainwater can be stored in inside planting bag, discharges when plant needs, strengthen retaining water retention capacity, improve plant survival rate, expand afforestation coverage rate; Instead of original stone, cement prefab, structure is simple, speed of application is fast, significantly can reduce engineering cost, constructs permanent software side slope, and greening vegetation speed is fast, forms natural side slope attractive in appearance.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.

Embodiment one: see Fig. 1-Fig. 2, a kind of rock slope timber solid earth greening alive structure, comprises cutting hole (2), timber (3) alive, planting bag (6).First, clear up domatic float stone, danger stone, weeds foreign material etc., unwrapping wire is got a little, on stable rock slope, dig cutting hole (2) with drill bit with horizontal spacing 2 ~ 3m, vertical clearance 1.5 ~ 2.5m, aperture upward, distributes in blossom type, aperture 10 ~ 20cm, hole depth is not less than 30cm; After having punchinged, water in hand-hole with water, treat that ponding disappears, complete infiltration, then in cutting hole (2), insert the Nutrition Soil that 10cm is thick; To make the timber alive (3) bundled, the side that otch is downward, and insert in cutting hole, between adjacent timber alive, make fence with plant branch (3) alive with the reinforcing bar (4) being no less than 20%, fence fixes with timber rope (5) of living; The planting bag (6) of mixture of soil, climbing plants seed, water-loss reducer, fertilizer will be housed, overlay successively above fence, the sack staple (7) that is connected connects into entirety, then, in the hole formed at planting bag and rock slope, fill Nutrition Soil, plant shrub (10) above, herbaceous plant seeds can be sowed in top layer, last covered with plastic film, reduces the evaporating loss of soil moisture, improves plant survival rate.
