Description
Technical field
The utility model relates to sand control technical field, especially a kind of sheet self adaptation nylon sand-protecting barrier.
Background technology
The existing desert of China and sandy land area reach 173.11 ten thousand km
2, account for 18.03% of China's territory total area.The direct economic loss that the whole nation is caused every year because of the desertification of land comprising desertification is about 4,700 hundred million yuan.Under existing technology, economy and natural environmental condition, the sandy land can administered in nearly decades is about 500,000 km
2.According to 1998 " national improvement of the ecological environment planning " issued by the State Council, in Desert Control, proposing immediate objective (2010) is 220,000 km
2, medium-term goal (the year two thousand thirty) is 400,000 km
2.
The mainly the Northwest, area that China's desertification is the most serious and the most concentrated, namely to the west of Helan Mountain, the Qilian mountains and Altun, Northwest arid district to the north of Kun Lun Mountain.Only sweet, new, cover, blue or green, Zang5Sheng (district) sandy land area just reaches 162.2 ten thousand km
2, account for 93.69% of the national sandy land gross area and 1/4 of national land surface.This region in national security, stability in border areas, national unity, Ecological Civilization Construction and socio-economic development all according in critical role, but the area that Ye Shi China ecological environment is the harshest and fragile simultaneously.Along with population increase, development of resources, the people such as oasis expansion are economic activity aggravation, cause a series of ecological environment problems comprising desertification, as Rive flood routing, vegetation degeneration, the soil erosion, Lakes Dry Up, sandstorm take place frequently, both the living safety of the arid biogeographic zone people had been jeopardized, also jeopardize the ecological safety of eastern region, and the international image of China is affected adversely.With the deterioration of the ecological environment that desertification of land and shortage of water resources etc. cause, not only jeopardize the survival and development of local people, increase the weight of poverty degree, and also serious threat is constituted to country's ecology, national defense safety and socio-economic development.Therefore, defend and control sand, the containment deterioration of the ecological environment has become the obstacle that Northwest arid district people's survival and development cannot be gone beyond.And first Desert Control problem will be considered to administer the situations such as district's weather, landforms and water resource.7 nefuds are had to be distributed in this region in eight nefuds of the whole nation, the sandy land that the whole district can administer in the recent period about 240,000 km
2, account for the half that area can be administered in the whole nation.Simultaneously, this district's drought, wind great Sha is many, and vegetation is rare, water resource famine, annual precipitation is many at below 200mm, and ecological environment is very fragile, and difficulty of governance is very large, depend merely on the sand control with biological measures that cost is low, effective, be difficult to prove effective, therefore general based on mechanical sand barrier, or the comprehensive sand control measure combined with the plant of mechanical sand barrier+appropriateness is just feasible.
In decades, domestic and international existing sand control technology mainly contains sand control with biological measures, machinery (engineering) sand control and chemical sand control three class.Wherein sand consolidation with biologic be the most effectively, the most lasting and this effect than the highest one, but the Northwest that China's desertification blazons, because of surface water shortage, amount of precipitation is few, and sand control with biological measures is difficult to prove effective; The multiplex mulseal emulsion of chemical sand-fixing, emulsion polymerization, the aqueous solution etc. spray in drift sand surface tackling quicksand, and reach the object of consolidation, but have chemical contamination because of its mulseal, other macromolecule organic costs are high, and the life-span is short waits application less; Application at most, the most generally machinery (engineering) fix the sand, and the comprehensive sand fixing technology that is combined with biofacies of machinery.Mechanical sand fixation is that the materials such as bavin, grass, nylon wire, gravel, clay are pressed on drift sand surface with certain height (0.2-1.0m), specification (band, trellis) paving, to reduce Shamian Island wind speed, increase Shamian Island resisting wind erosion, reduce grains of sand flowing, reach and fix the sand object.Comprehensively fix the sand be plant again on the basis of mechanical sand fixation, suitable careless seeds of planting, be issued to sand fixation in the mutual security effect of plant and other sand-protecting barriers.Therefore mechanical sand fixation is the one preferred technique that China's arid biogeographic zone is defended and controlled sand.
In arid biogeographic zone control of desert, main still based on mechanical sand fixation technology, the place be relatively good at moisture condition is aided with vegetative sand control.In mechanical sand fixation technology, applying maximum is faggot sand-protecting barrier, clay sand-protecting barrier and nylon wire sand-protecting barrier three kinds; Be proposed many chemical sand-fixing materialses in recent years in addition, but all in experimental stage, sand-fixing effect is all undesirable.
Gansu Province Zhisha Research Institute is invented and is applied clay sand-protecting barrier sand fixing technology for many years, be by sand dune near clay manually transport to the banded low bank of earth between fields that on sand dune, fortification about 20 centimetres is high, spacing 3-5 rice, there is good sand-fixing effect, its shortcoming is effort of taking a lot of work, cost is high, and be also subject to the local restriction with or without clay, inconvenience is generally applied.
Chemical sand-fixing materials is of a great variety, oil product class sand-consolidating agent can be divided into, synthesis high score subclass sand-consolidating agent, biomass resource class sand-consolidating agent, hydroscopic high-molecular resin, developing low-cost, high-effect, environmentally friendly chemical sand-fixing macromolecular material are the task of top priority, compared with biomass resource class sand-consolidating agent, petroleum-type, synthesis class sand-consolidating agent can not natural degradations, and while fixing the sand, can pollute desert area to some extent.And exploitation is fixed the sand and water-keeping material on the basis of reproducible natural polymer (lignin, cellulose etc.), both reach the object of vegetation of checking winds and fixing drifting sand, recover, turn avoid the pollution of other macromolecular materials to desert area.But at present also because of factor restrictions such as raw material, technology, cost life-spans, fail extensive use.
Faggot sand-protecting barrier arranges conveniently, pollution-free, environmental friendliness, and application is comparatively wide, but is restricted because of insufficient raw material, life-span short (4-5); Nylon (or plastics) sand-protecting barrier sand fixing technology is for primary raw material with HDPE etc., wire drawing machine ribbon shape sand proof net, coefficient of air infiltration 30-45%, with traditional checked sand hinder straws comparative lifetime is long, dustproof effect is better, lay and do not have more application by advantages such as local resources, restriction in season, convenient transportations, but cost is higher, construction is complicated, especially its coefficient of air infiltration is fixing, thus wind erosion is subjected at the sand ground that mobility is large, be subject to sand at the sand ground that mobility is little bury, thus have impact on effect and range of application.Wang Ji and the configuration waiting the artificial sand-fixation plant (200720032058.X) invented to imitate Arid Desert Area undershrub completely design and produce, and its complex structure, cost are high, effect of checking winds and fixing drifting sand is also limited; Therefore, how to solve arid shifting sand area nylon (plastics) Sand-fixation net subject to wind erosion, sand bury and construct convenient, reduce costs, just become the key cracking this sand fixing technology difficult problem.
