Description

A kind of guard sand control desertification prevention method

The present invention relates to a kind of sand control and end unconcerned method, particularly a kind of sand control with the fixing weaving of stake guard ends unconcerned method.

At present, the desert of land is affecting weather, is worsening environment, is threatening human existence and expanding economy.The desertification of land situation is also very severe, and except that slowly moved under the wind-force effect in the desert of level ground, the grains of sand on the sand dune produced sand, sandstorm weather under the wind-force effect.This bad weather has caused the concern of the whole society to the harm that the mankind bring, and takes some measures and contain desertification, constructs green screen, to improve the ecological environment.Existing method mainly contains: the vegetation method: the method with afforestation, kind grass forms vegetation, blocks external dust storm, is blown away by wind with the grains of sand that prevent sandy land surface, reaches the purpose of fixing the sand.But this method only is applicable to desert edge, has the place of planting trees and grass condition, and limitation is quite arranged.Longer because of its time limit that forms vegetation, performance sand fixation at short notice can't take effect.This passive solid method method makes that often because dust storm is too big the vegetation part is flowed or blow over and cover completely by the desert, and can't survive, all that has been achieved is spoiled.Mechanical Method: generally adopt sand-proof wall, the method for windproof dike or truncheon grass, though this method can temporarily play the sand prevention effect, because of service life too short, need repeat to be provided with, labour intensity is big, can not reach the purpose of fixing the sand of putting things right once and for all.Up to the present, yet there are no the report that utilizes the weaving eyelet fabric to check winds and fix drifting sand.

The purpose of this invention is to provide a kind of guard sand control and end unconcerned method, these method material therefor wide material sources, processing ease, windbreak function is remarkable, sand fixation is permanent, can construct at short notice to fix the sand barrier, finishes sand control rapidly and ends unconcerned task, fundamentally fix the sand, reach the result in unexpected positive of putting things right once and for all.

The object of the present invention is achieved like this: this method is to adopt the eyelet fabric of high-tenacity chemical fibre silk braiding, covers the jail in sandy land surface or top of sand dune with solid stake, forms sand fixing cover or every husky net.

Because the eyelet fabric that the present invention adopts high-tenacity chemical fibre strand to be made into, can make wind be able to by, alleviate the thrust of wind to cloth, can give wind with certain resistance again, reduce wind-force and wind speed,, not only strengthen the structural capacity of surface sand intergranular so cover firm guard with solid stake, reduction makes sand dune grains of sand ascension power to the power of directly blowing and the high speed winds formation pressure reduction of the grains of sand, stops the formation of sandstorm.The solid stake of eyelet fabric utilization is covered the jail and is got final product, so not only the eyelet fabric material source is extensive, and the operation that covers guard also is very easy to, sand-fixing effect is good, if be aided with measures such as planting trees and grass betwixt, can construct at short notice and fix the sand green screen, finish sand control rapidly and end unconcerned task, fundamentally fix the sand.Therefore, the present invention can reach the result in unexpected positive of putting things right once and for all, and this method is very easy to apply.

Below in conjunction with drawings and Examples the present invention is further described.

Describe specific embodiments of the present invention in detail according to Fig. 1-6.The textile that the present invention adopts is the eyelet fabric of high-tenacity chemical fibre silk braiding.This eyelet fabric can be according to actual needs cover 2 and upright cover 4 with making, cover the jail in sandy land surface or top of sand dune with

solid stake

3 or 5 then, can reach the purpose that sand control ends desert.Above-mentioned eyelet fabric adopts special process to be woven into, and its weaving is: utilize high-tenacity chemical fibre silk to form as warp, parallel twisted weave, wherein per two warps are one group, and strand is knitted, and a latitude hank is woven into netted eyelet cloth.The eyelet fabric that high-tenacity chemical fibre skein silk through twisting is made into, its warp-wise density is 3 groups-0.5 group/10 millimeters, latitudinal density is 3-0.5/10 millimeters.Can allow wind be able to by, alleviate the thrust of wind to cloth, can form certain resistance to wind again, reduce wind-force and wind speed.Therefore, this eyelet fabric can play the effect that sand control ends desert effectively as ground cover or upright cover.Sand-fixation method of the present invention can be defined as following several method according to the physical features in desert.

Fig. 1-2 is depicted as the cover net and fixes the sand method.It is with eyelet fabric sand dune in blocks 1 to be covered, and reinforces with solid stake 3 between ground cover 2 nets.Reinforce at top of sand dune with solid 5 with upright cover 4.Gu stake not only plays a major role to upright cover 4 and the ground cover 2 that covers firm eyelet fabric, and can also decompose wind-force to the pulling force that eyelet fabric produces, and protects it not to be damaged.Ground cover 2 can make that structural capacity increases between the grains of sand, and the wind-force of resisting is to the power of directly blowing of the grains of sand, prevents the pressure reduction that high speed winds forms and makes grains of sand ascension.Upright cover 4 plays the barrier effect, can effectively reduce wind-force and wind speed in the following scope of upright cover 4 height, has stopped most of grains of sand of carrying secretly in the wind simultaneously, prevents the formation of blown sand, has stopped moving of desert, helps fixing the sand.This method can be used for comprehensive sand control in big or small basin.

Fig. 3-4 is depicted as fill and fixes the sand method.It is with artificial or machinery sand ground to be piled up the sand barrier of certain altitude, and its height is decided with the distance of being fixed the sand, and also can directly do on the ground on the bigger sand dune of drop.Specific practice is to make ground cover 2 in the windward side on sand barrier or sand dune with eyelet fabric, covers sandy land surface, reinforces with solid stake 3 again.Reinforce with the upright cover 4 of eyelet fabric work and with solid stake 5 at top on sand barrier or sand dune.Action principle is fixed the sand method with the cover net.For improving and building the effect of fixing the sand, can be at the chase place of sand barrier or both sides, sand dune, plant grass 6, the tree 7 of drought-enduring easy life, below grass 6, tree 7, hole to the aquifer simultaneously toward the sand ground depths, inserted siphonage cordage 8 then, made underground water supply with grass 6, tree 7 growths (as shown in Figure 6) continuously through cordage 8.This law can be used for the sand control of big or small basin.

Figure 5 shows that barrier fixes the sand method.Be used for the small watershed sand control more.It is to check winds and fix drifting sand along the line or near the living area, desert at highway, railway.Concrete way is in highway or railway both sides, reinforces to stand with solid stake 5 and covers 4, covers 2 in the side of facining the wind with solid 3 simultaneously, grass planting 6 in the middle of road, trackside kind tree 7 with reinforcing.Its action principle is with above-mentioned desertification control method.
