The sand barrier made of the polylactic acid fiber (PLA) fabric overcomes the defect of secondary pollution, and has low cost; and the lay-in type sand barrier and the low vertical sand barrier are paved behind a sand hill required to be protected, thereby effectively protecting the sand hill and preventing the sandy soil loss. The utility module has the advantages of simple method and remarkable effect.

Description

A kind of sand-protecting barrier that utilizes Biodegradable material to make

Technical field

The utility model relates to a kind of sand-protecting barrier, particularly relates to a kind of sand-protecting barrier that utilizes biodegradable acid fiber by polylactic (PLA) to be made into, and belongs to the environmental technology field of defending and controlling sand.

Background technology

The formation of dust storm and geographical position and weather conditions have confidential relation, in case after dust storm forms, all will produce harm greatly to industry, agricultural, nature, environment, ecology etc.How administering dust storm, reduce or prevent dust storm to the negative effect that the mankind bring, is the major issue that current each side expert very pays close attention to and is concerned about.In order to prevent the influence of dust storm to the mankind, what application was very general now is exactly sand-protecting barrier.So-called sand-protecting barrier generally is the abbreviation of mechanical sand barrier, be the various forms of blinds that adopt materials such as bavin, grass, branch, clay, cobble on Shamian Island, to be provided with, control direction, speed, the structure that dust storm flows with this, change erosion cumuliformis condition, reach wind prevention and sand resistance, change purposes such as wind action power and landforms situation.In recent years along with science and technology development; some also occur and be used to make the new material of sand-protecting barrier; as the aging geotextiles of novel anti; acrylic sheet; the conventional chemical fiber; plastics etc.; because the application of these materials has instant effect; cost is low; characteristics such as easy construction; the effect that in foundation of highway sand prevention system and the preventing and fixing sand work of specific region, has quickly fixating sand; simultaneously; these materials are detachably reused; on drift sand, be provided with conveniently; can also combine with plant measures; the protection seedling; seed is not eroded and pile things on by drift sand, and fully drift sand just can be removed this class sand-protecting barrier after fixing when plant and to reuse to fix other local drift sands.Though utilize the conventional chemical fiber, plastics etc. are as cladding material, the sand-protecting barrier that filling inside is provided with the sandy soil of gathering materials on the spot, northwest drought at deficient vegetalitas sand-protecting barrier material resources, half-dried drought and sand area is with cheap simple and easy to do and be subjected to people's attention and approval, but meanwhile, because the non-biodegradation of these materials has also caused certain secondary pollution, also perplexing the large-scale promotion and the application of this technology, therefore, develop a kind of BIODEGRADABLE FIBER MATERIAL of utilizing, be woven into the container of definite shape and specification, the ground filling sandy soil of gathering materials on the spot again inside, it is a kind of both economical being used as sand-protecting barrier, the good method of environmental protection again, this also is the problem of current those skilled in the art and the investigation of expert's emphasis thereof.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art; a kind of sand-protecting barrier that utilizes biodegradable acid fiber by polylactic (PLA) material to make is provided, adopts a kind of sand-protecting barrier that utilizes Biodegradable material to make on flush system or vertical type collocation method protection sand dune.Acid fiber by polylactic (PLA) is manufactured by cornstarch and is formed, and uses the back by being decomposed into carbon dioxide and water behind the microbial action in the soil, and the protection on sand dune and the growth of plant are had good action, does not pollute and can not produce environment.

The technical solution of the utility model is achieved in that

A kind of sand-protecting barrier that utilizes Biodegradable material to make, comprise the fabric that Biodegradable material is made, described Biodegradable material is acid fiber by polylactic (PLA), and the sand-protecting barrier that utilizes described acid fiber by polylactic (PLA) fabric to make is cylindric, and described cylindric sand-protecting barrier diameter is 8-25cm.

Described cylindric sand-protecting barrier comprises the flush system sand-protecting barrier of the long cylinder that is used for the flush system paving mode and is used for the low vertical sand barrier of the short cylinder of low vertical paving mode that the height of described low vertical sand barrier is 15-35cm.

A kind of sand-protecting barrier that utilizes Biodegradable material to make of the present utility model has following advantage with respect to existing, technology:

1, the utility model has adopted the sand-protecting barrier that biodegradable acid fiber by polylactic (PLA) is made into as raw material, be configured on the sand dune by certain way, under the action of microorganisms in the soil, acid fiber by polylactic (PLA) can become nontoxic carbon dioxide and water, therefore environmental protection more can not produce secondary pollution to environment.

2, the utility model can be gathered materials on the spot the sand-protecting barrier that forms by the cylindrical knitting machine braiding, and the filling sandy soil have reduced transportation, and have not been subject to seasonal restrictions.

3, sand-protecting barrier of the present utility model adopts biodegradable acid fiber by polylactic (PLA); and biodegradable acid fiber by polylactic (PLA) is manufactured for cornstarch and is formed; so cost is very cheap; easy construction; effect is obvious, particularly to the sowing on the sand dune seedling, seed is not eroded by drift sand and pile things on plays a very good protection.
