Abstract

The utility model discloses a highway soil quality side slope live timber pile soil reinforcement structure which comprises a soil quality side slope (1), wherein sapling inserting and placing holes (2) are formed on the soil quality side slope (1), live timber piles (3) are inserted into the sapling inserting and placing holes (2), and nutritional soil (4) is stacked and filled on the periphery of the live timber piles (3) in the sapling inserting and placing holes (2). Through the digging of the sapling inserting and placing holes on the exposed soil quality side slope, the perennial live timber piles which can germinate and branch are planted to the exposed slope surface according to a certain depth and density, so that after the live timber piles are grown, main roots and side roots of the live timber piles can be pricked into a deep layer of a soil body and linked with the peripheral soil body, which achieves a role of anchoring and stabilizing soil and solves the phenomenon of collapse of a slope body within a short period of time.

Description

The solid soil structure of road soil-slope timber alive

Technical field

The utility model relates to the solid soil structure of a kind of road soil-slope timber alive, belongs to slope of highway and prepares the nursing technique field.

Background technology

Along with the speedway mileage open to traffic increase and high-grade highway construction to mountain development, highway two tributary causes are built highway and are excavated and the soil property bare side sloping left over is increasing, and these bare side slopings are not taked safeguard procedures, sloping body slump very easily appears after rain drop erosion, the sandstone that slump produces can pour in highway, cause highway and gutter to stop up, had a strong impact on traffic safety.Soil erosion has simultaneously destroyed domatic prototype structure balance, has increased domatic unstability, to around farmland and highway facilities caused very big influence, and the uncultivated and ecological environment disunity on every side of discontinuity influences attractive in appearance.

Summary of the invention

The technical problems to be solved in the utility model is, provides a kind of and can make soil property bare side sloping growth vegetation and shrub fast, and the road soil-slope that the prevents sloping body slump solid soil structure of timber of living can overcome the deficiencies in the prior art.

The technical solution of the utility model: it comprises soil-slope, offers sapling and insert the hole on soil-slope, is inserted with timber alive in sapling inserts the hole, and heap is filled with nutrient soil around the timber of living in sapling inserts the hole.

On soil-slope, be provided with the grass seeds layer.

The degree of depth that sapling inserts the hole is 30-70cm.

The aperture that sapling inserts the hole is 6-10cm.

On the grass seeds layer, be equipped with nonwoven.

The length of timber alive is 60-120cm, and the bottom is cut and is miter angle.

Compared with the prior art, the utility model is established sapling and is inserted the hole by digging on exposed soil-slope, the timber perennial alive of giving birth to branch that will germinate is planted exposed domatic by certain degree of depth and density, like this after the timber of living is grown up, its taproot and lateral root just can penetrate the deep layer of the soil body and the soil body of periphery connects, reach the effect of anchoring stable soil, can solve the sloping body phenomenon of caving in a short time.On sloping body, sow grass-seed, grass-seed can grow fast, can play water and soil conservation effect in advance, grow up difficult the early stage that remedies timber alive, sapling inserts the spacing between the hole, the physics plantation condition of insertion depth and the openings of sizes best survival rate that all to be applicants obtain through long-time test repeatedly.On the grass seeds layer, lay nonwoven, can improve water retention like this, increase to motility rate, shorten growth cycle.Main material of the present utility model is local indigenous tree simultaneously, can economize on the use of funds significantly, and local seeds can well adapt to this place's environment again, can further improve survival rate and growth rate, is fit to current national conditions, has excellent popularization and is worth.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Embodiment: as shown in Figure 1, finishing solid soil needs following process:

1. to soil-slope 1, carry out on-the-spot geotechnic investigation, understand the trees of one's native land of local climate and local spontaneous advantage, selected timber alive 3 mostly is rudiment in 3 years take root fast kind such as locust tree, weeping willow, the bark of eucommia, Chinese white poplar etc., and it is preferential easily to survive seeds with this locality, grass seeds is that cold season and warm season mix, easily select growing height 30cm with interior strong stress resistance, adapt to low level management, have the certain internal force of sowing certainly grass seeds.

2. the timber 3 selected shrub diameters of living are 2-5cm, the arbor diameter is 3-8cm, length is 60-120cm, the bottom is cut and is miter angle, before using the timber 3 of living, put it in the green plant growth regulator aqueous solution and fully soak, the plant that easily takes root was soaked 1-3 hour with 30-50mg/kg, and the plant that difficulty is taken root was soaked 4-8 hour with 100mg/kg.

3. stone, the weeds foreign material of cleaning on the soil-slope 1 are cleaned with water and are fallen slow grade of side slope, make the side slope after the finishing not have the adverse slope phenomenon, and soil-slope to the greatest extent 1 may be smooth.

4. unwrapping wire is got a little on soil-slope 1, determines that sapling inserts the position in hole 2, and sapling inserts hole 2 and adopts quincuncial arrangement, pile spacing 50-150cm.

5. offer sapling downwards from putting of soil-slope 1 and insert hole (2), the degree of depth that sapling inserts hole (2) is 30-70cm, and the aperture is 6-10cm.

6. be inserted with timber 3 alive in sapling inserts hole 2, heap is filled with nutrient soil 4 around the timber 3 of living in sapling inserts hole 2, the nutrient soil of preferred high humility.

7. at the end winding plastic film of timber 3 of living, and broadcast sowing grass seeds, fertilizer, water-loss reducer etc. on soil-slope 1, the grass seeds consumption is 30kg/m ²

8. lay nonwoven on the grass seeds layer, periodic maintenance can be finished the solid soil structure of soil-slope timber alive.

Claims

1. a road soil-slope work timber is consolidated soil structure, it comprises soil-slope (1), it is characterized in that: on soil-slope (1), offer sapling and insert hole (2), be inserted with timber alive (3) in sapling inserts hole (2), the timber (3) of living in sapling inserts hole (2) is piled on every side and is filled with nutrient soil (4).
