Abstract
The utility model relates to a sand binding barrier made from a rough straw paper honeycomb board, and is formed by a big pane enclosed by a small pane formed by the crisscross insertion of the rough straw paper board coated with a polyester. The utility model has the advantages of the cheap fabrication cost and the convenient construction, which does not pollute the environment, and has an extensive application prospect in managing the desertification and preventing the harm of a sand storm.
Description
Technical field
The utility model relates to a kind of toilet paper honeycomb plate to fix the sand to hinder.
Background technology
Wrapping blue railway has 55 kilometers by Tengger desert southeast line, and 16 kilometers of location, Shapotou mostly are tall and big intensive mobile trellis dune group, and natural conditions are abominable, and amount of precipitation is low, does not have underground water again and can utilize.Since 1956, through 30 years three generations people's unremitting effort, explore finally based on admittedly, admittedly hinder combination, based on vegetative sand control, the technical measures that vegetative sand control and machinery fix the sand to combine.55 kilometers railway both sides, adopt 1m * 1m straw checkerboard barrier sand-protecting barrier to set up north wide 500 meters (some places are 300 meters), the railway sand prevention protection system that south is wide 200 meters has prevented the harm of drift sand effectively, for vegetative sand control is created a stable condition.Over more than 30 year, utilize vegetable seeds self water retaining functions such as oily wormwood artemisia, sand sagebrush (Artemisia filifolia), hedysarum scoparium, caragana microphylla, arrow-leaved oleaster of psammophytes, building up preferably through 8-10, artificial vegetation, coverage scale can reach 30%.Along with vegetation coverage increases, sand ground natural conditions environment improves, and forms the green together natural cover for defense, thereby guarantees that the blue railway three of bag is unblocked during the last ten years.As time goes on, the straw checkerboard barrier of laying then is rotten through erosion by wind and rain; Some psammophytes is owing to drought and water shortage, and it is withered to have failed, and the vegetative sand control achievement that three more than ten years were obtained faces new wind erosion threat again.Again repair and,, buy and collect difficulty because wheat straw is the raw material of papermaking to the careless lattice in laying side, innerland, desert; The 2nd, laying straw checkerboard barrier needs are artificial many, financial cost is high; The 3rd, the transportation difficulty; The 4th, the life-span of wheat straw has only causes such as 2-3, has been impossibility.Therefore people's exploration of the application of new material and the new measure of preventing and fixing sand, new model of having to sight is invested.Chinese patent 02294372.2 discloses a kind of " cellular plastic knitting Sand-fixation net ", in the location, Shapotou, coastal beach is applied the result that preventing and fixing sand is obtained.But weak point has pollution to environment, and the fixedly needs of plastic wire are manually pounded into timber wedge, and are time-consuming.
Summary of the invention
The purpose of this utility model provides a kind of straw board preventing and fixing sand barrier based on husky sand control, the thinking of suiting measures to local conditions, gathering materials on the spot, and utilizes its architectural feature, prevents moving of drift sand, realizes the purpose of vegetative sand control.
Technical solutions of the utility model are to realize like this
A kind of toilet paper honeycomb plate fixes the sand to hinder, it is the lattice that forms by the crisscross grafting of the straw board of surface applied polyester layer, crowd around into by lattice again that big grid combines, the specification of lattice is 0.05m * 0.05m-0.1m * 0.1m, the specification of big grid is 1m * 1m-2m * 2m, hinders high 20-40cm.
The utility model compared with prior art, the beneficial effect of its advantage and generation is:
1, straw board surface applied polyester layer has waterproof, anti-marquis, corrosion-resistant function, long service life; When reaching certain time limit, the differentiation of straw board natural degradation, do not produce pollution;
2, be convenient to carrying, in the construction, as long as straw board is pegged graft in length and breadth, bury the grid foundation with sand, the time and labour saving can large-arealy be applicable;
3, process raw material rich, cheap, but suitability for industrialized production;
4, spread psammophytes seed in lattice, under certain moisture, temperature condition, sprout, growth, thereby can realize the purpose of vegetative sand control;
Description of drawings
Fig. 1 is a schematic diagram of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described again
A kind of toilet paper honeycomb plate fixes the sand to hinder, be that straw board 1 crisscross grafting by the surface applied polyester layer forms three row's lattices 2, crowd around by three row's lattices 2 again and be combined into big grid 3, the specification of lattice 2 is 0.05m * 0.05m, the specification of big grid 3 is 1m * 1m, bury the grid foundation with sand, form the dotted grid seam of large tracts of land.
Learn from open-air site observation test: in the windward side, the stream streamline is wave.When dust storm fixes the sand to hinder through the toilet paper honeycomb plate that is provided with, all there is eddy current to produce, after circling round, cross sand-protecting barrier, when entering next big grid 3, the end, fall in the surface layer air velocity, and drift sand carrying dynamics weakens thereupon.The net sand drift is by behind the grid, and it is long-pending husky that grid is produced all around, after the long-pending effect of sufficient erosion, network underlying surface character obtains changing, comparatively smooth and stable concave curved surface is formed on big grid 3 bottoms, and ground forms the biological breadcrust layer and promotes soil-forming process, for vegetative sand control is created a stable condition.
