Description
Technical field
The invention belongs to environmental engineering technical field, particularly relate to a kind of method that composite curing agent is reinforced the domatic ecology of soil-slope.
Background technology
Strengthen environmental protection is the significant task advancing socio-economic development.In the work progress of the infrastructure such as highway, railway, water conservancy, mine, the destruction of original place looks vegetation is inevitable, spoir, abandons stone, excavation etc. and can leave a large amount of bare side slopings to harmonious natural environment.Slope reinforcing method mainly contains engineering reinforcement and reinforced by plants.Engineering reinforcement adopts usually wipes one's face, beats the forms such as face, whitewashing, hook (filling) seam, domatic revetment, but the method is generally only applicable to the sty of unsuitable vegetation growth, cannot realize ecological reinforcing for soil-slope.Vegetation is reinforced general employing and litters, plants grass and plant shrub (trees) form, though the ecology that the method can be applicable to soil-slope is reinforced, but before vegetation growth or the region of vegetation sparse, still there is the problem such as the erosion caused by sloping surfaces, soil erosion in the domatic soil body, even can affect the growth of vegetation to a great extent.Polymeric consolidator as a kind of soil stabilising material of novel environment friendly, advantages such as the amount of participating in is less because having, convenient transportation, construction are simple, ecological, environmental protective and receiving much concern.
Chinese patent application 200710021619.0 proposes " ecological soil stabilizer and preparation method thereof ", and this ecological soil stabilizer comprises water or deionized water, comonomer 1: vinylacetate, comonomer 2: methyl methacrylate or with comonomer 3; Comonomer 3: acrylate; Polyvinyl alcohol; Emulsifier sodium lauryl sulfate or with OP2-4 or be; Initator (persulfate).Though the method has good environment fitness and can the advantage of Promoting plant growth, also have the following disadvantages: one is that curing compound liquid viscosity is comparatively large, permeability extreme difference, and the cured layer of domatic formation is very thin, can not meet the requirement of domatic solidification generally; Two is that hardening time is extremely long, is difficult to ensure solidification effect in practical operation; Three is cured layer poor water retention property, easily dry and cracked, affects vegetation growth.
Chinese patent application 201110106789.5 proposes " a kind of polyurethane-based ecological sand-fixing agent and preparation method thereof ", this sand-consolidating agent is by base polyurethane prepolymer for use as, dispersion stabilizer and solvent composition, base polyurethane prepolymer for use as is obtained by polymer polyatomic alcohol and vulcabond polycondensation reaction, polymer polyatomic alcohol is made up of Polyoxypropylene diol, polyoxyethylene glycol and easy degradation polymer glycol, the mass ratio of Polyoxypropylene diol and polyoxyethylene glycol is 1: 3 ~ 5: 1, and easy degradation polymer glycol accounts for 13 ~ 23% of polymer polyatomic alcohol gross mass; The mass ratio of polymer polyatomic alcohol and vulcabond is 4: 1 ~ 7: 1.Though the method has good high/low temperature climate adaptability and the advantage of resistance to ag(e)ing, also have the following disadvantages: one is that the curing compound shelf-life is short, be difficult in practice preserve; Two is that hardening time is extremely short, has been difficult to construction, directly will affects construction quality within its hardening time; Three is that cured layer thickness is thin, is difficult to meet slope reinforcing requirement.
Chinese patent application 201110106794.6 proposes " a kind of dust-proof sand-fixation method ", and the method is by polyurethane-based ecological sand-fixing agent dilute with water, and the weight percent concentration of base polyurethane prepolymer for use as is 0.5 ~ 5%; Then sand-consolidating agent dilution is sprayed on sandy soil, forms cured layer on sandy soil top layer; Wherein, the active component of described polyurethane-based ecological sand-fixing agent is base polyurethane prepolymer for use as, described base polyurethane prepolymer for use as is obtained by polymer polyatomic alcohol and diisocyanate cpd polycondensation reaction, described polymer polyatomic alcohol is made up of Polyoxypropylene diol, polyoxyethylene glycol and easy degradation polymer glycol, the mass ratio of Polyoxypropylene diol and polyoxyethylene glycol is 1: 3 ~ 5: 1, and easy degradation polymer glycol accounts for 13 ~ 23% of polymer polyatomic alcohol gross mass; The mass ratio of polymer polyatomic alcohol and diisocyanate cpd is 4: 1 ~ 7: 1, and described easy degradation polymer glycol is the mixture of poly-epsilon-caprolactone glycol, polylactic acid diol or its arbitrary proportion.Though the cured layer that the method is formed has the advantages such as good antiscour and wind erosion-resistance performance, also have the following disadvantages: one is that hardening time is extremely short, within its hardening time, be difficult to construction; Two is that cured layer thickness is thin, is difficult to meet slope reinforcing requirement; Three is that curing compound dilution is sprayed directly on the sandy soil after broadcasting sowing vegetation grass seeds, easily causes the displacement of grass seeds, slope vegetation distributing homogeneity extreme difference.
In sum; how to overcome the deficiencies in the prior art; effective solution is in environment exploitation is built; cause because of excavation that ecosystem is unbalance, natural vegetation damages or exposed soil-slope occurs soil soil property be loose, water content reduction, easy-weathering, easily cause the erosion caused by sloping surfaces, the disaster problem such as soil erosion, slope body cave in, river obstruction, landslide, water pollutions, become one of emphasis difficult problem of urgently capturing in current environmental engineering technical field.
Summary of the invention
The present invention seeks to a kind of method providing composite curing agent to reinforce the domatic ecology of soil-slope for overcoming the deficiencies in the prior art, cured layer of the present invention has good scour resistance, wind resistance, water stability, and water conservation, ventilative, be beneficial to the functions such as vegetation growth, practical.
The method that a kind of composite curing agent that the present invention proposes is reinforced the domatic ecology of soil-slope, is characterized in that comprising the following steps:
