Description

The preparation method of the husky body of modification

Technical field

The present invention relates to the husky utilization of resources and desert, desert treatment field, particularly a kind of preparation method that can obtain the husky body of the modification with earth characteristic.

Background technology

(1) desert, desertization and harm thereof

Desert and desertization are the great environmental problem that face of mankind nowadays is the severeest.

Whole world land surface is 1.62 hundred million square kilometres, takes up an area 30.3% of the ball gross area, and wherein about 1/3 (4,800 ten thousand square kilometres) are arid, semiarid Desert Area, and expanding with the speed of 4 ~ 60,000 square kilometres every year.And desert area has accounted for 10% of the land gross area, the soil of 43% has been also had to be faced with the threat of desertization.

China is that desert, the world distributes one of maximum country, is also in the world by one of country of dust storm and desertization serious harm.The numeral that China national State Forestry Administration, P.R. China announced in 2011, national sandy land area 1,730,000 square kilometres, accounts for 18% of territory total area, and wherein desert area has 80.89 ten thousand square kilometres, accounts for 8.4% of area.

Harm in Desertification Process comprises stream and sand dune reach causes farmland covering, and river, reservoir, water channel block, and highway is buried, also make whole environmental degradation, loss of land resource, and the related regional economy caused is slow, the society of society's instability etc., economic problems.

Desertization directly causes the land resources of the preciousness that can directly utilize sharply to reduce.Desertization directly causes land deterioration, and soil structure destroys, the nutrient loss of soil, and these recoveries need many decades, centuries, even thousands of year.The deterioration of grasslands that desertization causes, the advantage grass seeds being suitable for livestock edible is reduced gradually, even completely loses, herbage becomes short, sparse, and output obviously reduces, and grassland capacity for raising livestock on the grasslands greatly declines.Desertization causes river, reservoir, water channel to block, and such as, the average annual sediment transport in the Yellow River 1,600,000,000 tons, wherein just has 1,200,000,000 tons from Desertification.Desertization causes railway bed, bridge, culvert to damage in some areas, makes highway subgrade, road surface sand, forces highway communication to be interrupted, and even makes highway discard.Because dust storm is pressed hard, thousands of herdsman is forced to move to alien land, becomes " eco-refugee ".The data display that China national State Forestry Administration, P.R. China provides, 20 end of the centurys, desertify every year with the speed expanded of 3436 square kilometres, within every 5 years, just have an area being equivalent to Beijing's administrative division size to lose value because of desertification, the population that the whole nation affects by desertization reaches 1.7 hundred million.Desertification of land, desertification not only worsen ecotope, and decline productivity of land, threatens rivers safety, and aggravate the poverty of husky district.

Desertization causes the ecosystem and natural environment deterioration, and natural calamity takes place frequently, and is one of disaster the most serious of facing mankind.Natural, ecological is the integral framework that a various factors restricts mutually, by the poised state kept relative stability according to certain rule.Desertization changes the physical features on earth's surface, land greatly, destroy Radiation budget balance, bring out weather and environmental change, cause the water and soil loss of Desertification more serious, green vegetation sharply reduces, ecotope sharply worsens, and rare animals and plants disappear or extinction, and diversity of organism suffers serious destruction.After climatic anomaly and the ecosystem are destroyed, cause the speed of desertization to be aggravated, both form vicious circle, are degrading natural environment further, make the people of Desertification lose the basis of depending on for existence, and cause the natural calamity in other area.According to monitoring, if China urban air pollution owner finely ground particles, this and desertization are closely related.Dust pollution the productive life environment of the wide geographic area people, and sandstorm is frequent, have impact on people ' s health.

The seriousness of Deserts in China is also that the population statistics involved is huge, and it directly or indirectly affects the life (account for the whole world and perplex 40% of population by desert and desertification) of nearly 400,000,000 people.The direct economic loss about 64,200,000,000 yuan of China's desertification harm is annual, and the indirect economic loss about 2,889 hundred million yuan that desertification and derivative harm thereof cause is annual.If without effectively preventing countermeasure, be in the big cities such as the Urumchi of desert band, Lanzhou, Xi'an, Yinchuan, Taiyuan, Huhehaote, Beijing, Tianjin, eventually can become city, desert one by one, large quantities of common people will become eco-refugee.

(2) measure of desert and desert treatment and achievement

The fundamental way of Desertification Control is the character according to hazards of sand storms, takes various technical measures, weakens the wind speed of near surface formation, reduces the sediment discharge in air-flow, delays or stop sand dune to move forward, to reach the object weakening or avoid hazards of sand storms.For a long time, the measure of harm (sand control) that prevent and control sandy storm, Chinese scholars is summarized as engineering sand control (machinery) measure, controlling sediment by plant measure and chemical sand control measure three major types it.Controlling sediment by plant measure and engineering sand control measure belong to reduction wind speed, and weaken stream intensity, chemical sand-fixing is then consolidation Shamian Island, control Shamian Island wind erosion process development.

Vegetative sand control is also called sand consolidation with biologic, is by the means such as fencing and serike, reaches control desert, stablizes oasis, improve a kind of technical measures of husky district environmental quality and productive potential.Vegetative sand control why can tackling quicksand, and one is because psammophytes has flourishing root system, can the grains of sand of consolidation around it, in addition the accumulation of dry branches and fallen leaves, is conducive to organic gathering after rotting, and impels husky pedogenesis, change sand ground character, make drift sand tend to stable; Two is due to after serike on sand dune, adds the roughness on earth's surface, thus also just adds the resistance to wind, reduces wind speed, weakens and inhibits stream movable.

The main method of vegetative sand control comprises: (1) envelope sand-base cultivation grass, protection natural vegetation; (2) afforestation is fixed the sand; (3) desert edge wind prevention and sand resistance forest belt is built; (4) build inside, oasis and protect field, forest network.

Vegetative sand control can improve the ecological condition in the husky territory of vegetative coverage, promotes that sandy plant community develops to good direction, forms the stable ecosystem, is conducive to increasing bio-diversity.

But, desert area drought, cold and hot drastic change, wind great Sha is many, natural environment is very harsh, be not suitable for the growth of plant generally, therefore, the effect of vegetative sand control is subject to the restriction of desert characteristic and natural environment, particularly under the condition without irrigation, as the time arid especially, due to water deficient, plant undergrowth or the mortality of plantation can be made.

Sand-prevention engineering measure utilizes weeds, crotch, cob wall or other structure etc., drift sand established air partition or covers Shamian Island, preventing Sand Movement.Engineering sand control measure has fast feature of producing effects, but the protection phase is short, is therefore often applicable to the area in the traffic lines of drift sand serious harm, important industrial and mineral base, farmland and residential area, and adopts for during the growth of protection sand-fixation plant.Main method has: hinder husky fence (high vertical sand barrier), and mechanical sand barrier (establishing checked sand hinder straws), clay fix the sand, the husky engineering of transporting (type such as lower wind-guiding, feather row and sediment transport section).

The mechanical function principle of engineering control measure is all the resistance of motion by increasing stream, retardance energy dissipating, make it slow down and impel the deposition of sandy soil particle, be a kind of provisional measures for sand prevention, for the harm of drift sand, only play the effect of " controlling table " fixed the sand.

Chemical sand-fixing be active dune () upper spray chemical bonding material, cover layer is formed on drift sand surface, or infiltrate in the sand of top layer, loose sand material bonding is got up to be formed bonding course (duricrust), thus prevent wind-force from raising blowing of sand material and carrying, reach tackling quicksand, prevent and treat the object of sand damage.Chemical sand-fixing is generally used for the area that hazards of sand storms causes heavy economic losses, (as airport, traffic lines (railway, highway), military installations and important industrial and mining area), and normal and vegetative sand control matches, as the complementary of vegetative sand control and transitional arrangement.

The effect of chemical sand-fixing effect, not only relevant with the character (as chemical composition, mechanical composition) of drift sand surface particles, and also relevant with physico chemical property (as molecular structure, molecular size, viscosity, absorption affinity) of chemical sand fixing material itself etc.Chemical sand fixing material conventional as asphalt emulsion, oily Ye Yan ore deposit liquid, synthetic resin, synthetic rubber etc., also can use some natural organic matters, as brown coal, peat, municipal refuse refuse, resin etc.

Asphalt emulsion is that our times various countries to be applied in chemical sand-fixing engineering material the most widely.But emulsified asphalt in use yet exists because the asphalitine in pitch and resin are easy to by destructions such as the oxygen in air, light, heat, moisture and microorganisms, oil content declines.The aggravation gradually of this change, causes asphalt performance to degenerate, and as softening point rising, needle penetration declines, and ductility reduces, and causes unity layer slowly to become fragile, harden, and loses plasticity, occurs aging, so that finally ftractures and destroyed by wind sapping, loses sand fixation.

(3) the basic difficulty of desert and desert treatment and Problems existing

The dreamboat of control of desert is, desert can either be made to stablize, again can growing plant, namely makes in " change oasis, desert ".But the husky body in desert is discrete particle, the basic difficulty of control of desert is, the husky body in desert easily moves, is difficult to water conservation and stores nutrient.Comprehensively current sand control measure, people are not difficult to find, existing desert control method fundamentally solves far away desert and easily moves, be difficult to water conservation retaining and store this two hang-up of nutrient.

Existing desert control method fixes the sand to be main, no matter adopt engineering (machinery) measure, plant measures and chemical measure, it is not from the attribute improving Desert Sand body itself, only avoid the harm that husky movement causes, therefore from its method and mode, still belong to passive sand control, the flowability problem in desert to a certain extent or can be overcome within short-term, but be difficult to fundamentally to solve the difficult problem that desert is difficult to water conservation retaining and is difficult to store nutrient, " change oasis, desert " that distance people wish still has larger distance.

1. engineering (machinery) measure temporarily can change the physical aspect (natural existing way) that desert exists, it is a kind of provisional measures for sand prevention, for the harm of drift sand, only play the effect of " controlling table " fixed the sand, desert is of short duration is tamed, cannot reach the effect of " effecting a permanent cure ", after long-time, its true colours still can be recovered in desert.

2. chemical sand-fixing is that employing sand-consolidating agent is sprayed on husky surface, and to reach the object of fixing the sand, the sand-consolidating agent effects on surface grains of sand retrain, and form one stablize containment vessel on grains of sand surface, and then husky body is stablized, and do not flow.But, chemical sand-fixing materials often adopts spray method to be formed, only can form constraint in the scope that husky surface is very thin, the constraint that surface is formed is once destroyed, to be difficult to recover, and chemical substance weather resistance determines its sand control can only the flowing of the husky body of temporarily shutoff, and can not reach the object of long-term stability, its cost drops into high.

The earliest, spray the sand-consolidating agent emulsified asphalt often adopted, after sprinkling, sand dune surface skining average thickness little (usual 2 ~ 3cm), after using the several years (usual 3 ~ 5 years), bonding course starts fragmentation; Meanwhile, the emulsified bituminous materials of sprinkling is unfavorable to environment, and itself is not the nutrient component of plant growth, and therefore its effect is only fixed the sand; Asphalt material aging is poor in addition, will not have sand fixation after break inactivation.

At present, people have developed many macromolecular sand-fixation agents, after sprinkling, and sand dune surface skining thickness thin (being generally 0.2 ~ 0.5cm), surface retains few, and cracking often appears in dry rear surface; Meanwhile, sand-consolidating agent generally needs certain hour consolidation, is difficult to meet aqueous dispersion or dissolving again after consolidation after spraying, its water retention mainly by closing the part hole on top layer, part blocks underground evaporation of water and realizing, its material itself there is no water retention; Further, cortex itself does not have moisture capacity, thus can not protect containing nutrient, can not adapt to the generally growth of plant.So, the feature of sand-consolidating agent and fix the sand its long-term behaviour of fixing the sand of structures shape of layer and be difficult to obtain basic assurance.

3. the applicable elements of vegetative sand control is usually subject to weather and environmental limit

It is husky that vegetative sand control utilizes plant top to hinder sediment barrier, the root of plant is utilized to fix the sand, micro climate and micro-soil environment can be changed to a certain extent, but, the basic difficulty of vegetative sand control is that desert itself is unfavorable for plant growth, as unstable in desert and wind-driven sediment is frequent, desert is barren, water deficient and be difficult to water conservation, temperature adjustment etc. and all plant had a negative impact.

Wind-driven sediment can make the harm that plant is subject to deflation, sand buries and sand cuts, wind-driven sediment can solve with engineering protection measure and chemical sand-fixing, but desert water deficient and be difficult to the basic difficult problem of water conservation retaining, the applicability making traditional plant fix the sand receives very big restriction.

In sum, expect to obtain a kind of control of desert measure, even if husky body has the same stability of soil, moisture capacity, gas permeability have and store the function of nutrient, namely, make husky body " soil ", fundamentally solve the difficult problem that husky body easily moved, and be difficult to water conservation retaining and stored nutrient, make its plant growth preferably, and then fundamentally improve the form of husky body and carry out control of desert.

When the husky body of the modification adopting the present invention to obtain is for control of desert, compare with other control of desert measure of prior art, the present patent application has the following advantages:

1. compared with fixing the sand with engineering

Engineering Sand-fixing Measures changes the roughness on drift sand formation surface, does not improve structure composition and the way of restraint of husky body self, only plays the effect that physics improves.The present invention improves the particle composition rule of husky body by bonding material, while the way of restraint improving husky body particle, its structure is made to have the function of water conservation, retaining, maintenance nutrient, namely, make husky body " soil ", the husky body of this modification is more suitable for plant growth.

2. compared with chemical sand-fixing method

The present invention is embodied in many aspects from the different of chemical sand-fixing.

First, present invention achieves " soil " of husky body, the method realized with chemical sand-fixing and effect have fundamental difference.

The present invention adopts will be had water conservation, bonding and store the constraint materials of effect such as nutrient function and the method for husky body mix, its effect can realize " soil " of husky body, and each Plants can be planted, and chemical sand-fixing is by the method for surface spraying chemical sand-fixing materials, its effect only can realize the consolidation of surperficial husky body, prevents the movement of husky body.The constraint material that the present invention adopts and husky body under certain condition mix form the husky body of modification, the husky body of the modification formed has moisture capacity, function is supported in storage, and the husky body of the modification that the constraint material that the present invention adopts is formed all has good stability in dry, wet two states, the constraint of formation can reconfigure according to the change of dry and wet state, change.The present invention is the entirety constraint system changing husky body, and the constraint system only strengthening husky surface is essentially different.The present invention is used for desert, the husky system of husky surface 3 ~ 50cm can be made the husky body of modification, and then the husky body in desert is not easily flowed, possess moisture and the nutrient of plant growth indispensability simultaneously, reach the object of basic sand control.Chemical sand-fixing measure is by spraying chemical sand-fixing materials in husky surface, strengthened by the constraint of the husky body of infiltration (penetration depth the is generally less than 3cm) effects on surface of sand-consolidating agent, only change the way of restraint of husky surface, its degree of depth is general more shallow, its constraint has irrecoverability, comparatively large on the impact of natural environment, ordinary disbursements is high.The effect of cured layer itself is single, can only provide consolidation, not have water conservation, water storage, and the function of nutrient.

The intensity mechanism fundamental difference of the present invention and chemical sand-fixing.

Chemical sand-fixing is by spraying in husky surface the consolidation that chemical consolidation material realizes surperficial husky body, in order to play the effect of the overall husky body of consolidation, the husky body requirement of strength in surface is higher, compression strength even really will could prevent destruction and the movement of husky body more than 1MPa, the present invention is then within the scope of certain thickness, Sha Tiyu had bonding, the constraint material mixing of water retaining function, realize the constraint each other of overall husky body, prevent the movement of husky body, how strong the constraint of husky body reality do not need, this point can carry out analogy with soil, from test, after adopting the present invention, husky body in a way, achieve " soil ", although by regulating constraint material type and consumption, can the surperficial consolidation strength of husky body be accomplished enough high completely, but test and analysis show, the surperficial compression strength of husky body can play the effect of stabilized sand body in very little scope, chemical sand-fixing effect can be reached, achieve again " soil " of husky body within the scope of certain thickness, get final product planting plants simultaneously, realize fixing the sand again and eucyclic object.

Compared with chemical sand-fixing, the present invention also has the restorability of destruction.

The performance of the constraint material that the present invention adopts determines the feature of the restorability of the destruction of modification sand, the constraint material that the present invention adopts is dissolvable in water in water, after liquid object after dissolving and husky body mix form the husky body of modification, moisture is wherein difficult to lose, even if after loss of water, if meet water again, constraint material can be dissolved in the water again, again the modification forming same purpose is husky, and this process can infinitely repeatedly, therefore the husky body of modification that the present invention is formed has the restorability of destruction, but chemical sand-fixing is then completely different, the material behavior that chemical sand-fixing adopts determines the irrecoverability of destruction, chemical sand-fixing is in order to ensure surperficial husky body consolidation, normal employing intensity is higher and do not have the sand fixation material of reversal properties, but surface strength is once destroy, cannot recover again on the original basis, only have again sprayed on material to recur and arrive consolidation, otherwise after surperficial husky body destroys, husky body below it is exposed to surface again, along with time integral, original effect of fixing the sand will progressively be lost, fixing the sand object and effect just cannot ensure.

As can be seen here, the method that the present invention makes the husky body of modification by mix is different from the method that the infiltration by chemical sand-fixing materials is fixed the sand in itself.

3. compared with vegetative sand control method

The fundamental difference of the present invention and vegetative sand control is, vegetative sand control can only " be taken stopgap measures ", and the present invention fundamentally changes husky volume property, realizes husky body " soil ", thus the vegetative sand control realized truly, therefore the present invention is only arranging of " effecting a permanent cure " of control of desert.

Vegetative sand control utilizes vegetation rhizome the mode that husky body retrains to be played to the effect fixed the sand, but husky body self property is also not suitable for plant growth, moisture easily runs off, husky body also cannot be stablized, under wind effect, husky body moves frequently, plant is difficult to growth, even if short-term plant growth, in the presence of a harsh environment, if moisture can not effectively be preserved, plant is also difficult to continued growth, even withered, therefore the effect of vegetative sand control is not only subject to the restriction of local climate condition, is also difficult to realize its effect fixed the sand for a long time.The present invention then has fundamental difference with vegetative sand control.The present invention is the basic point from vegetative sand control, namely the performance improvement of husky body is started with, realize " soil " of husky body, not only there is the effect of stabilized sand body, also make husky body have the function of water conservation, retaining, storage nutrient, husky body the is possessed condition of plant growth, achieve the condition of the stable of husky body and plant growth, planting also could really realize, and therefore from certain angle, the present invention is only the vegetative sand control of real meaning.

In order to contrast the effect of the present invention and vegetative sand control, the present invention has also carried out comparative trial.Sodium Polyacrylate is taked to have bonding as in modification sand by method of the present invention, the material of water retention, form modification thus husky, by making while of common husky body husky and moistening for modification in outdoor crushed stone, placement thickness is 15cm, and the surface difference multiple vegetable seed of spreading and grass-seed, after 1 day, common husky body becomes dry, modification still keeps wetting state behind husky some skies, and under the prerequisite of not watering, grass-seed and the vegetable seed on the husky surface of modification germinate, but wither again after the grass-seed of common husky surface and vegetable seed germinate and thirst, after the plant that modification sand is planted, once water and can meet the water demand of plant in interval for 10 ~ 30 days, sapling on modification sand grew up through 2 years, about two meters are reached, the tomato that modification sand is planted and dish seedling can normally eat, suitable with planting plants growing way in soil.Plant after 1 year, husky body connection is netted by root system of plant, with the outward appearance of soil, character all without difference, and the plant that former years rot can be described as nutrient again, husky body is stablized further, the plantation effect of modification sand forms benign cycle, and sand fixation is also really feasible, economical, and also making desert become fertile soil becomes possibility.

4. compared with other method: as water-absorbing resins

Super absorbent resin is containing strongly hydrophilic group, usually has the macromolecular material of certain degree of cross linking.Water insoluble and the organic solvent of super absorbent resin, water absorbing capacity is generally the hundreds of of own wt to several thousand times.Swelling after the water suction of this material is hydrogel, and after pressurized, water is also not easily extruded; After resin drying, can repeated multiple timesly absorb water, its moisture overwhelming majority absorbed can slow releasing, utilizes for plant absorption.

The constraint material that super absorbent resin and the present invention adopt has essential distinction.Constraint material of the present invention has cohesiveness and adhesiveness, has water-soluble, relies on the cohesiveness and adhesiveness and the husky bodily form that retrain material into about bundle.This constraint can present different character along with dry, wet change, and constraint also can reconfigure.

5. the present invention has significant economy, exploitativeness and the feature of environmental protection.

First, the husky body of the modification that the present invention is formed is compared with existing sand fixing technology, and its disposable investment construction cost has certain economic benefit.The constraint material that the present invention adopts can form the husky body of the modification that meets the demands under the condition that volume is minimum, can comprise one or both and above mixture in natural polymer and modification solid matter thereof and synthesis macromolecule solid matter by water-soluble solid organic materials as taked some; As: one or both and above mixing in polyvinyl alcohol, polyethylene glycol oxide, polyethylene glycol, Sodium Polyacrylate, sodium carboxymethylcellulose, hydroxypropyl methylcellulose and cellulose ether or copolymer, constraint material only accounts for a few one thousandth of husky body weight ratio, and material is conventional chemical materials, material cost is also lower, therefore material cost is also lower in principle, and construction method is also comparatively simple, only adopt the common process such as stirring, machinery, labour cost are also lower, and therefore comprehensive method of investment cost will have considerable economy.For sodium carboxymethylcellulose, add 20kg sodium carboxymethylcellulose material in 1 cubic meter of water, market unit price is 10 yuan/kg; The husky body about 4 cubic metres of correctability, considers artificial, machine cost 100 yuan, then the husky body 1 cubic metre of modification, cost is 75 yuan, be layed in husky surface by 10cm, 1 cubic metre of husky body of modification can lay 10 square metres, then the disposable input cost of the husky body Desert Control of modification is 7.5 yuan/square metre.

Secondly, different from conventional tune fixing method, the husky body of the modification that the present invention is formed has recyclability, after an investment construction, the husky body of modification can plant each Plants, the husky physical efficiency of modification stablizes root system of plant, and the root system of plant stabilized sand body conversely, and the rhizome, leaf etc. that rot can be used as again nutrient, for husky structural reform appearance becomes benign cycle, desert, by really becoming available class land resources, has the advantages that once invest long-term gain, therefore its indirectly economy by inestimable.

Exploitativeness of the present invention is stronger.The present invention adopts material to be existing chemical industry common used material, as polyvinyl alcohol, polyethylene glycol oxide, polyethylene glycol, Sodium Polyacrylate, sodium carboxymethylcellulose, hydroxypropyl methylcellulose and cellulose ether are the conventional thickening material of chemical industry, production method is simple, feasible, cost is lower, the construction method of the present invention's employing is simple in addition, master operation is the mix of the husky body of point preparation being spread on husky liquid solution and modification, and therefore the present invention is easy to grasp, and implementation is stronger.

The present invention also has the feature of environmental protection, and constraint material of the present invention, can adopt the material being rich in nutrition, and the growth that itself can be plant provides necessary nutrient, also can add the necessary nutrient of plant growth wherein.The present invention can reconfigure the constraint of husky body according to husky body dry wet, change, and has restorability.Constraint material of the present invention adopts conventional material, and such as sodium carboxymethylcellulose, itself be also food additives, environmentally safe, expense is low, easy to implement.

In summary it can be seen, the technical measures of present patent application achieve husky body soil from principle, fundamentally can play the effect of sand control.

Embodiment

Certainly, also following steps can be adopted:

B. by step a get sand, water and above-mentioned solid matter mix in any order and mix evenly after namely form the husky body of modification;

Two kinds of methods obtaining the husky bodies of modification do not have essential distinction, and regardless of order by merging, the final material had in cohesiveness and adhering solution formed has thickening property and water-soluble, could obtain cohesiveness and adhering solution, realize goal of the invention; The husky body of modification that General Requirements is formed after having cohesiveness and adhering solution and husky (order by merging is not limit) mix has the feature of plastically deformable or forms rarer state and have plasticity after moisture evaporation.

Experiment shows, repeatedly can be dissolved in the water and there is thickening property and water-soluble in water, then can form the material with cohesiveness and adhesiveness solution has multiple, as: one or both and above mixing in polyvinyl alcohol, polyethylene glycol oxide, polyethylene glycol, Sodium Polyacrylate, sodium carboxymethylcellulose, hydroxypropyl methylcellulose and cellulose ether or copolymer; After being dissolved in the water, can not only (such as mass percent is 5 ~ 10%, more than even 10 ~ 20% or 20%) makes there is cohesiveness and adhering solution in larger volume (solid content after moisture evaporation) situation, and can when less volume, such as less than 5%, even less than 1%, make and there is cohesiveness and adhering solution.Also some auxiliary agent be can add during use, cohesiveness and the adhesiveness of solution improved or improve further; Inorganic substances and organic substance also can be composite, to obtain having cohesiveness and adhering solution desired by us.

To there is cohesiveness and adhering solution (containing nutrient) mixing and after mix described in Sha Tiyu, just can be formed have soil property, the husky body of the modification of particle+constraint+hole (also can be husky, water and can be water-soluble material by different order mixing also mix and formed); When wet, moisture and nutrient store in the solution and solution sticks in the hole between husky body particle, so the husky body of modification not only has the character that water conservation storage is supported, and have the viscoelastroplasticity character as wet soil; When dry, particle between the husky body of the modification that bonds after the material consolidation be originally dissolved in the water, so, the husky body of modification has the character of the porous solid as dry soil, and, material after described consolidation can absorb moisture and again be dissolved in the water, so the husky body of modification also has the ability of absorption moisture (containing nutrient).

In the husky body structure of modification of particle+constraint+hole, due to make the grains of sand produce adhesion (cohesive strength) constraint this as added enter material (be solution when moisture is large, moisture hour changes solid into gradually), after material filling pore, the hole of the husky body of modification can be less than the hole of unmodified front discrete husky body, but, due to after the solution mix that husky body and material are formed, no longer directly contact completely between the grains of sand, described material is had between contact point, make the spacing between husky body increase (and in the solution that material is formed moisture evaporation after, the solid content of material itself is less, its ratio occupying hole is little), therefore, along with the change of " pine " " tightly " of the Contact of particle, the hole of the husky body of modification also can be greater than the hole of the discrete husky body be even far longer than before modified, to sum up, the hole of the husky body of modification both can be less than, also the hole of discrete husky body before modified can be greater than, experiment shows, the porosity of the husky body of modification can change between 10 ~ 80%, this porosity ranges is not only greater than discrete husky body, and be greater than the soil of nearly all type, this just shows, we can regulate the porosity of the husky body of modification by different proportionings and structure, husky body is made to contain the moisture of our expectation, nutrient and air.Moreover, in the pellet pores structure of the husky body of modification, both had interconnected pore, and also had dead-end pore, wherein interconnected pore rate is 5-70%, and the husky body of modification can by interconnected pore and the outside exchange that water and air occurs.

In structure due to particle+constraint+hole in the husky body of modification, the porosity of the restraining force of constraint material (material) and the husky body of modification can regulate, so, after moisture evaporation in the husky body of modification, the intensity of the porous solid as dry earth formed can regulate in a very large scope, intensity is when below 10Kpa, the husky body of modification is the solid relatively loosened, when intensity is between 10 ~ 50Kpa, the husky body of modification is shaping solid loose preferably, after intensity is more than 50Kpa, the husky body of modification toughens gradually, the husky body of modification harder during in order to obtain dry, can by regulating constraint and porosity, its intensity is made to reach more than 200Kpa.

The husky body of the modification become by sand, mechanical state is exactly a kind of " soil ", there is stream and become (time wet) and solid (time dry) two states, and, " soil " of dry solid state can be converted into " soil " of wet rheology after absorbing moisture, and " soil " of wet rheology can be converted into " soil " of dry solid state after moisture evaporation, by the constraint between adjustment particle and space, we can regulate the stream of the husky body of modification this " soil " to become (such as viscoelastroplasticity) or solid property, obtain from " sandy soil " to " loam " to " clay " various, " soil " of suitable variety classes plant growth, therefore, sand is become " soil ", for the mode of husky body, desert can be utilized by modification of the present invention husky body.

According to the difference of modification object, construction requirement or economy, low viscous solution (below viscosity 100mpas) can be prepared, also moderately viscous solution (viscosity is between 100mpas ~ 5000mpas) can be prepared, also configurable full-bodied solution (viscosity is greater than 5000mpas) and husky body mix and form the husky body of modification.

After preparation forms the husky body of modification, due to the husky body of modification and the extraneous exchange that moisture can occur, so, in the husky body of modification, the water content of solution can change, and then, the viscosity of the solution in the husky body of modification except relevant to the material behavior of added material and except, also relevant to the change of water content, but described in have in cohesiveness and adhesiveness solution moisture evaporation after, the solid content of material is geostationary, so we using the weight ratio of added material and husky body as controlled quentity controlled variable, can determine the volume of described material.According to the difference of material character, add the kind with the material in cohesiveness and adhering solution in the husky body of modification and volume to select in a larger scope, after moisture evaporation, when the weight ratio of the material added and the husky body of modification is within the scope of 1:30-8000, we all can obtain the husky body of modification expecting based on different modification object requirement to obtain.

The husky body of the modification obtained based on particle confinement principle, its constraint can not only produce adhesion between sand grain, and adhesion can be produced between husky body and other material, so when Sha Tizhong is doped with appropriate gravel, plant roots, stem, skin, animal wastes, corpse residue etc., the character its main body with soil characteristics can not be changed, so, based on the method for particle confinement, we not only can transform simple sand or sandy soil, and can transform the wasteland containing sand and other material in Gobi desert etc.; Utilize this character, we even can add rigidity or flexible fiber, fabric, rattan, film tape, sheet etc., improve or regulate the stability of the husky body of modification, crack resistance or toughness; Except can adding the water-soluble various fertilizer of energy, nutrient, other fertilizer also can be constrained in the husky body of modification, for plant growth provides nutrition; We can also add water-absorbing resins, acid-base accommodation material etc., improve the soda acid performance of the husky body of the water suction of the husky body of modification, water retention property or modification.

On the husky body of this modification during planting plants, whole modes of planting plants in prior art soil can be adopted, comprise membrane curing, booth growth, to resist outside severe natural environment; In a word, do not have internal to distinguish with planting plants in soil, do not repeat them here.

Contrast shows, have after cohesiveness and adhering liquid and sand mix forms the husky body of modification by described, pave structure sheaf again that formed in common husky surface, and described liquid is sprayed directly on common husky surface and the superficial layer that formed has the difference of essence, is embodied in:

The first, realize fundamental difference in principle.

From the composition rule of particulate matter, the husky body of modification is based upon the present inventor to propose on the basis of " particle confinement " principle, is a kind of thinking of brand-new sand " soil ".

Constraint type between common sand is " contact ", only there is contact and frictional force in its contact point, and without any node adhesion with in conjunction with moment (as node draws force and moment), therefore, common sand can only by contact and frictional force balancing gravity and external force, its node can not bear and draw force and moment, otherwise, husky body just will occur particle arrangement sudden change and unstability.

And will have after cohesiveness and adhering liquid and sand mix forms the husky body of modification, restraining force between its particle node is " adhesion ", it enough can either produce the restraining tensile force be separated between opposing particle, enough can produce again the restraint moment that opposing particle rotates, simultaneously, it can also produce node pressure and frictional force, therefore, it can limit all degree of freedom of particle, but this restriction is again limited, particle node is while generation constraint reaction, can also extend, rotate and slide, therefore, its constraint type and common sand fundamental difference, that is, the husky body of modification both can resist external force, again can be limited under external force and stably move.On the other hand, in the husky body of modification, being constrained to " adhering to constraint " of husky body whole interior, this constraint is formed after having cohesiveness and adhering liquid and sand mix, on microscopical structure, this constraint is after each sand surface uniform covers one deck adhesion layer, contact again between particle and formed, therefore, this constraint has universal property and restorability, that is, all can be formed " adhering to constraint " at any point cantact between particle, and after being separated, contact between particle, this binding feature can be recovered again.Therefore, the husky body of modification has the viscoelastroplasticity character of even macroscopic and isotropic, the same with the mechanical characteristic of wet soil.

Once after moisture evaporation in the husky body of modification, " adhering to constraint " just will become " consolidation constraint ", namely, space arrangement between sand will be fixed, and husky body can bearing load, has some strength, show as the character of porous solid, just as dry soil.Meanwhile, as previously mentioned, after meeting water, " consolidation constraint " becomes again " adhering to constraint ", and husky body becomes viscoelastroplasticity body from solid.In the husky body of modification (when no matter doing or time wet), there is connection, open space all the time, with the external world, the exchange of moisture, nutrient and air occurs.

But, if only there is cohesiveness and adhering spray liquid in husky surface by described, only can form one deck adhesive film in husky surface, the liquid of infiltration under adhesive film is very limited, and this layer of adhesive film dry after, just become solid film, obviously, this method itself is not draw based on " particle confinement " principle, with the thinking fundamental difference of sand " soil " yet.Be sprayed on adhesion layer (being thin layer after solidification) and the liquid of infiltration under adhesion layer in very thin scope thereof of husky surface, only define constraint in husky surface, this constraint, by by force to weak, does not have all even isotropic nature, comes in and goes out very large with the character of soil; Adhesion layer (thin layer after solidification) resides in sand grains surface, can be completely closed by the hole between sand, this with have be communicated with, the husky body fundamental difference of the modification of open space, also with the thinking fundamental difference of soil; In the husky body of modification constrain in the husky body inner homogeneous of modification, equivalence has an effect, with the property class of natural soils seemingly, and spray layer and only have an effect near surface, not there is the characteristic of natural soils.

The second, fundamental difference in architectural characteristic.

On structure dimension, the husky body of the modification formed after mix, its physical dimension can regulate as required, and paving thickness is changeable, when structural thickness is large, can plant the plant that plant is tall and big, and structural thickness hour, the plant that plant is short and small can be planted; And the thickness spraying layer is only formed near surface, its physical dimension is difficult to regulate as required.

On intensity and wear properties, the husky body of the modification formed after mix, what formed is plate body, has the mechanical characteristic of plate, when the strength of materials is relatively little, still possesses higher bearing capacity, reach the object of fixing the sand, and, the cracking of plate body or destruction, do not destroy the effect that it fixes the sand, play principle with the intensity of soil layer and stability consistent; Meanwhile, the husky body of modification in its thickness range, viscoelastroplasticity body when no matter being wet, or porous solid time dry, all can either stablize the root system of plant, growth and the development of root system can be adapted to again, with soil curing plant with to adapt to the mechanical characteristic that root system of plant develops consistent.But, spray the skin layer formed, there is the mechanical characteristic (very large with the characteristic difference of plate) of film, must ensure enough intensity, just can reach the object of fixing the sand, top layer is once destroy, just be difficult to the husky body under constraint top layer, its effect of fixing the sand just is difficult to play; Meanwhile, between the husky body particle under surperficial top layer, there is no additional constraint, be still the husky body of nature, can not root system of plant be stablized, with the characteristic fundamental difference of soil.

On pore characteristic, the even pore distribution of the husky body of modification, has and is communicated with and the open space contacted with the external world, with the external world, the exchange of moisture, nutrient and air can occur, and spray the skin layer formed, enclose husky body and contact with extraneous.

At water conservation, in water storage and evaporation characteristic, first, the water conservation of the husky body of modification, water storage principle is directly stored in by water to have in cohesiveness and adhering liquid (as previously mentioned, removing solid matter in liquid is all water), be difficult to evaporation and run off, with the water conservation of soil, Water storage characteristics is very similar, its water conservation, storage capacity is very strong, and this ability can regulate in a larger scope, the growth of various plant can be adapted to, show in the enforcement in Chongqing, the husky body of modification of the high storage capacity obtained by regulating match ratio, can rice cultivation flourishing, until gather in the crops full paddy, secondly, the evaporation characteristic of the husky body of modification is also similar with soil, and after the moisture evaporation in the surperficial grains of sand, inner moisture not directly and extraneous contact, from top to bottom slow evaporation, keeps reasonably evaporation and a water storage gradient.But, spray the skin layer formed, its water conservation, the characteristic of water storage and evaporation and the husky body fundamental difference of modification, firm sprinkling and the water resided in skin layer, only can penetrate into the very little scope in below top layer, be easy to evaporate and form the solid film closed with the external world, now, film itself is without storage capacity, its water storage principle is: utilize the free moisture in husky body, evaporate because temperature is uneven in temperature, cohesion, the complex process be hampered, it is finally made to rest on the region of film close beneath, the water storage principle fundamental difference of this water storage principle and soil and the husky body of modification, the moisture stored is few, only can adapt to the growth of minority plant.

3rd, the plantation of plant is different with growth characteristics.

First, in the plantation characteristic of seed, implement contrast and show, for the husky body of modification, seed can be embedded in the husky body of modification, or is sown in the husky surface of modification, different according to the germination characteristic of seed, and various seed all can germinating growth; And for the method for surface sprinkling adhesion layer, after various seed is buried or broadcasted sowing, must spray thin layer adheres to cover layer, but, because the moisture below surface coating is few, the seed that part is imbedded do not germinate or germination poor; Meanwhile, due to surface coating solidify after can close seed (and moisture evaporates), the seed broadcasted sowing is after covering thin layer, and same appearance is not germinateed or the situation of germination difference.Therefore, the husky body of modification has the character of soil, seed sprouting preferably.

In the plantation characteristic of plant, enforcement contrast shows, the husky body of modification can plant each Plants, according to the difference of the husky body thickness of modification, the herbaceous plant that plant is short and small can be planted, also can plant the tall and big herbaceous plant of plant, also shrub can be planted, further, when the local thickness of the husky body of modification and volume can stablize root system of plant, also high megaphanerophyte can be planted; But, form thin layer at spraying liquid and adhere to after cover layer, the moisture evaporation especially in thin layer cover layer and after forming solid thin-film layer, serike destroys thin layer for cost, therefore, after spraying thin layer cover layer, be suitable for hardly planting any plant again; And spray adhesion layer after serike again, few of real value.

In the growth characteristics of plant, the general well-grown of plant in the husky body of modification, with general soil and indifference, according to the difference of the husky body thickness of modification, the husky body of modification can the short and small herbaceous plant of growth plant, also can the tall and big herbaceous plant of growth plant, also can grow shrub and arbor, but, only when thin layer sprays covering, the general growing state of plant is poor, and, sand below thin layer cover layer, is difficult to the tall and big herbaceous plant of firm plant (as corn etc.) and trees.

It should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
