Abstract
A method for control landslip includes constructing top ditch for guiding the runoff on the top to decrease the flush of runoff to land, building up valley dam for buffernig flood and sand and stabilizing ditch bed, and planting vegetation on original collapsed surfaces. Its advantage is high effect.
Description
Technical field
The present invention relates to a kind of soil and water conservation method, especially relate to a kind of improvement method that collapses the hilllock.
Background technology
At present, administer that to collapse the classic methods in hilllock be to adopt " on stop stifled in the middle of cut " method.Promptly collapse and back down gutter, contour horizontal ditch, product word ditch and horizontally disperse, dredge and collapse the top runoff as vegetation project in conjunction with contour; Collapse mound mouth is built check dam, and slow flood gulps down sand and joins the barnacle spillway and drain off floodwaters, and covers vegetation in the paddy, forms the plant biological dam, crosses the water filter sand, fixedly the ditch bed; Collapse wall and cut the slope and open level, accomplish the step of one-level one-level from top to bottom, for forestation planting grass creates conditions." cut the centre " one ring in the method collapses under the high and steep situation of wall running into, and needs a large amount of human and material resources of cost and financial resources, and technical requirements is also higher.Have only to those collapse that wall is precipitous, the avalanche amount is big so that active type serious threat traffic, river course, water conservancy projects, farmland and village safety collapses the hilllock, is necessary just under the condition of construction requirement that cutting the slope opens level possessing.
Summary of the invention
What the object of the present invention is to provide a kind of " on stop stifled in the middle of protect " collapses hilllock improvement method, and this method expense is few, easy to operate, effective.
For achieving the above object, the present invention includes following step: 1) build from ditch head 3～5m place and be used for carrying-off top runoff, reduce ditch head runoff and wash away and control the gutter that the ditch hair is opened up collapsing the top, hilllock, gutter is mild and to collapsing the both sides, hilllock, it ditch depth 0.2～0.3m, gutter bottom width 0.4m, two banks were than 1: 1; 2) build check dam at collapse mound mouth, slow big vast sediment trapping is stablized the ditch bed, reduces and collapses the wall relative altitude; 3) keep original wall landform that collapses, collapse originally and cover vegetation on the wall.
Of the present inventionly collapsing the concrete steps that cover vegetation on the wall originally for utilizing the seed broadcasting machine, grass seeds, fertilizer, wood fibre, erosion are prevented that agent etc. from adding water and stir after, the employing pump spills cloth to collapsing wall, the grass-seed length of embedment should be not less than 5cm when broadcasting sowing.
Of the present invention collapse originally on the wall cover vegetation concrete steps for after grass seeds, fertilizer, soil, water etc. are fully mixed, be ejected into equably with spray gun and collapse on the wall, cover with harmless cloth, suitably sprinkle water.
Of the present invention collapsed originally cover vegetation on the wall concrete steps for to constitute plant biological bag by two-layer harmless cloth, in the middle of plant biological bag, accompany grass grain and chemical fertilizer, the grass seeds plant biological bag is layered on collapses on the wall, fine earth on the upper cover, suitably sprinkling water gets final product.
Of the present invention is the hole of 5～8cm, dark 10～15cm collapsing the concrete steps that cover vegetation on the wall originally for collapsing on the wall with the drilling tool excavated diameter, every m
2About 5～10, liana or herbaceous seeds, fertilizer, soil moved in to improve the original, erosion are prevented the mixture of agent etc. from implanting in the hole.
Of the present invention collapsed originally the concrete steps that cover vegetation on the wall for the gradient slow collapse wall, directly plantation shrub and lay down in grass on domatic.
Can according to collective area situation can open several gutters in the step 1 of the present invention more, also can construct horizontal ditch more than collapsing top 10m, row holds combination.
In the step 2 of the present invention when check dam become silted up full after, can on the one-level check dam, continue to build and increase, keep big sediment trapping storage capacity, catchment area is bigger collapses the hilllock and also should set flood spillway and drain off floodwaters, and protects check dam not bursted.
The present invention can afforest apace collapses wall, collapses the slope, and control is collapsed the hilllock and corroded effectively, compares with existing method, and expense still less, and is more easy to operate, and effect is better.
The specific embodiment
Embodiment one: about 60 ° of the gradient, high 20m, wide 28m's collapses the hilllock, builds gutter, ditch depth 0.3m, wide 0.4m from collapsing top ditch head 5m; Collapse mound mouth is built native check dam, height of dam 5m, and the wide 1.5m of dam crest, the gradient is 1: 2 outside the dam, inner slope 1: 4; Collapse the wall employing and broadcast sowing mode, use the seed broadcasting machine, grass seeds, fertilizer, wood fibre, erosion are prevented agent etc., add and spill cloth to collapsing wall after water stirs, the grass-seed length of embedment is not less than 5cm when broadcasting sowing.Be unearthed through 10～20 days seed germination, vegetation coverage was more than 60% after fertilising, ridging etc. are managed and protected in 1 year, 1 year then substantially closing collapse wall, reach the purpose of greening, collapse the hilllock erosion and be effectively controlled.
Embodiment two: about 80 ° of the gradient, high 35m, wide 10m's collapses the hilllock, from collapsing the gutter that dark 0.3m, wide 0.4m build in ditch head 5m place, top; Collapse Gang Kou and build height of dam 2.5m, the wide 0.8m of dam crest, inner slope 1: 0,1: 0.5 the mortarless stone check dam in outer slope, flood spillway is opened in the centre on dam; Collapse wall and adopt the mode of sowing grass seeds by duster, after grass seeds, fertilizer, soil, water etc. are fully mixed, be ejected into equably with spray gun and collapse on the wall, cover with harmless cloth, suitably sprinkle water, vegetation coverage reached 50% in 1 year, but wall is collapsed in closing in 1 year.
Embodiment three: about 75 ° of the gradient, high 30m, wide 37m's collapses the hilllock, and from collapsing the gutter that dark 0.3m, wide 0.4m build in ditch head 5m place, top, 10m builds horizontal ditch; Collapse Gang Kou and build height of dam 5m, the wide 1.5m of dam crest, inner slope 1: 4,1: 2 the native check dam in outer slope, flood spillway is opened in the centre on dam; Collapsing wall and adopt bunch planting way, is 7cm, the hole of 12cm deeply collapsing on the wall with the drilling tool excavated diameter, every m
2Dig 8, liana or herbaceous seeds, fertilizer, soil moved in to improve the original, erosion are prevented the mixture of agent etc. from implanting in the hole, vegetation coverage reached 50% in 1 year, but wall is collapsed in closing in 1 year.
