Abstract
The invention provides a novel rock-soil body side slope ecological stabilizer which is used for solving the problem of water and soil losses caused by rain wash on a side slope soil body, playing a role in corrosion resistance and also achieving the aim of ecological restoration of an exposed side slope of a rock body. The novel rock-soil body side slope ecological restoration and corrosion resistance stabilizer is characterized by being prepared by anionic polyacrylamide, potassium chloride, ethyl acrylic ester, epoxy acrylic ester and water according to the proportion, the blending mass ratio under the condition of the room temperature is 0.5: 2: 0.5: 0.5: 96.5 in sequence, the blending proportion of the stabilizer and the soil body makes the moisture content of the soil body after blending be controlled between the best moisture content of the soil body and the plastic limit of the soil body, then grass seeds and shrubs are added to be blended, the mixture is aired to be the moisture content state under which wet spraying operation requirement is met, the size of the caked soil body meets the operation requirement of a selected wet spraying machine, finally the pump-type wet spraying machine is utilized for wet spraying, the grass seeds are formed by blending ryegrass, dodonaea viscosa and Chinese pennisetum according to the mass ratio of 1: 1: 1, and the shrubs are formed by blending magnolia multiflora, leucaena leucocephala and pyracantha fortuneana according to the mass ratio of 1: 1: 1.
Description
Technical field
The present invention is a kind of slope ecological agent for fixing, belongs to building (ground) field of engineering technology.
Background technology
For the special rock soil body of southwest, as the sandy soil fine particles that complete severely-weathered granite gneiss etc. forms, loose without adhesion stress between particle, meet water softening expansion and be highly susceptible to washing away loss; Expansive soil, the normal disaster problem such as water-swellable, dehydration contraction that occur in laterite area.At present, for the aspect such as diaster prevention and control and rock mass bare side sloping ecological recovery of sandy soil loss problem, dilative soil, also there is no effective and practical counter-measure, the slope of highway of such special soils is first adopted conventionally to the engineering protection measures such as the protection of anchor pole (rope) sash beam or arch slope, carry out again the greening measures such as plant biological bag or alien earth sparging, to guarantee stability and the aesthetic property of such slope of highway.But, process to greening from engineering protection, exist complex procedures, long in time limit, involve great expense and the problem such as protection against erosion poor effect.Therefore, be badly in need of the ecological agent for fixing of a kind of novel rock and soil slope of exploitation, corroded or promotion bare side sloping ecological afforestation by rain drop erosion for anti-slope soil, recover vegetable layer thereby effectively solve, avoid a series of ecological environment problems such as deterioration and biological chain destruction of soil erosion, landslide, mud-rock flow, Partial little climate, keep having significant role for solidifying with vegetation of roadbed side slope.The research and development of ecological solid slope technology, to beautifying road environment, are preserved the ecological environment, and prevent erosion, and guarantee driving safety is all significant.
Summary of the invention
The object of the invention is to provide a kind of slope ecological agent for fixing, solves slope soil because of the soil erosion problem that rain drop erosion causes, and plays erosion-resistant effect, also can solve the problems such as rock mass bare side sloping ecological recovery.
Technical solution of the present invention, is characterized in that this agent for fixing is configured and forms in proportion by PAMA+potassium chloride+ethyl propylene acid esters+epoxy acrylate+water, mixes to join mass ratio and be followed successively by 0 under room temperature condition.5∶2∶0。5∶0。5∶96。5, anion polyacrylamide molecular weight requires to be not more than 6mg/mol, and ion degree is not more than 20%, and selects pulverulence, potassium chloride is selected pulverulence, ethylacrylic acid ester molecule amount requires to be not more than 5mg/mol, and selects pulverulence, epoxy acrylate molecular weight requires to be not more than 5mg/mol, and selects pulverulence, water is drinking water, layoutprocedure is first by soluble in water the potassium chloride weighing in proportion, stir, after all dissolving, the ethyl propylene acid esters weighing is in proportion put into potassium chloride solution, stir to whole dissolvings, then the epoxy acrylate weighing is in proportion put into the mixed solution preparing, stir to whole dissolvings, finally the anion polyacrylamide weighing is in proportion put into potassium chloride, ethyl propylene acid esters, in epoxy acrylate mixed solution, stir to whole dissolvings, this agent for fixing and soil body mix ratio are that the soil moisture content after mix is controlled between soil body optimum moisture content and soil body plastic limit, then mix grass-seed and shrub and carry out mix, airing is to the moisture content state that can carry out wet shot job requirements, and keep soil body caking size dimension to meet selected wet-spraying machine job requirements, finally utilize pump formula wet-spraying machine to carry out wet shot processing, grass-seed adopts rye grass+akeake+Chinese pennisetum to mix at 1: 1: 1 in mass ratio, consumption is that every cubic metre of soil body mixes respectively 40～60 grams of grass-seeds, shrub adopts spends more the mixing in 1: 1: 1 in mass ratio of lily magnolia+new white popinac+torch fruit, and consumption is that every cubic metre of soil body mixes respectively 40～60 grams of shrubs.
