Description

Retaining sandbox and sandbox dike

Technical field

The utility model relates to a kind of sand-protecting barrier setting, relates more specifically to a kind of retaining sandbox and sandbox dike of the sand that can durable interception advances with the saltation form.

Background technology

Desertification and control thereof are one of maximum and the most urgent problems of influence surface in the environment and development global problems.There are more than 100 countries and regions to have the desertification problem in the world.China is one of the most serious country of desertification in the world.Relate to west, northern territories such as Xinjiang, the Inner Mongol, Gansu, Ningxia, Shaanxi, Hebei, Shanxi, Liaoning, Beijing, Tianjin.Dust storm is to ecological environment, agricultural, forestry, animal husbandry, traffic, water conservancy, factory, mine, tourism, town and country construction, the commerce and trade logistics of China; Economic, cultural, social sustainable development and the people's productive life etc. cause great harm.How to strive to find conscientiously, the countermeasure and the means of efficient, lasting control wind erosion desertification (desertification), become the Chinese government and the west, northern numerous people is very great and urgent subject.

Desertification is to be the natural calamity of outstanding feature with the wind-sand activity.See that from fluid-mechanics point of view its essence is the result of stream motion.Stream is the mixed flow of the solid particle (grains of sand) of a kind of air-flow and carrying thereof, and its formation depends on the interaction of the physical medium of two kinds of different densities of the air and the sandy face of land.Wind gets in the air-flow and is handled upside down because wind makes the grains of sand break away from the face of land when the loose sandy face of land, causes the development of sand ground wind erosion, produces dust storm and moves, and stream occurs.

Dust storm motion has suspended, saltation, wriggling and move three kinds of citation forms in the top layer, is principal mode with the saltation.The saltation of the so-called grains of sand is meant that the grains of sand after receiving the wind-force effect of raising up to break away from the face of land to get into air-flow, just constantly obtain the momentum acceleration and advance from air-flow, and under the effect of grains of sand own wt, to fall rapidly with respect to very little acute angle of horizon.Because the density of air is much littler than the density of the grains of sand, the resistance that the grains of sand receive in motion process is less, when falling Shamian Island, still has sizable momentum.Therefore, the grains of sand itself that not only fall might rebound, and continue to bound forward, and because its percussion, and the entering jump of splashing of a part of grains of sand around can also causing to fall and break a little will cause a series of chain reaction like this.The grains of sand are done the motion of jump form so continuously, are called saltation.

A large amount of research of scientist shows, the strong wind sand of carrying under one's arms moves, i.e. the said stream of scientist mainly is to carry out pressing close to the height of surface, sand dune below 10 centimetres.Field inspection shows that also the sand amount overwhelming majority (more than 90%) of air-flow carrying is in the height on 30 centimetres on the sandy face of land, to pass through, and wherein concentrates in the airflow layer that is distributed in 0-10 centimetre (accounting for 80%) especially again.This shows that the dust storm motion is a kind of sand carrying phenomenon of ground proximity.Because the sand amount in the stream more than 90% is in the height on 30 centimetres on the face of land, to pass through, therefore adopt to exceed Shamian Island 20-30 centimetre sand-protecting barrier, just be enough to control the activity of sand dune surface wind sand drift.And set up sand-protecting barrier also is the more general technology of in the measure of sand fixing technology systems engineering, using.On the route that stream passed through, run into stopping of sand-protecting barrier, wind speed will be affected and reduce; The part of sand of carrying under one's arms will be deposited on sand-protecting barrier around; Hinder the saltation of the grains of sand with this, reduce the sedimentary loading of stream, thereby play the effect of control hazards of sand storms.The method of setting up sand-protecting barrier commonly used is with branch, faggot, stalk, gravel, clay, lath, wheat straw, moulds plate and similar material is provided with the various forms obstruction on Shamian Island; Change wind erosion aeolian accumulation environment; Slow down the direct effect of wind-force to the face of land; With control stream direction, speed, structure, reach the effect of fixing the sand, hinder sand, sediment trapping.Specific practice has:

1. straw checkerboard barrier sand-protecting barrier: wormwood is embedded in the sand, expose 10--15cm one section, make length and width and respectively be one meter grid, can prevent effectively that promptly drift sand from moving.Also available careless fence is a frame with timber, is embedded in the sand, is woven into net with wormwood in the wooden frame, and its height is more than one meter.Strong wind can pass in the grass net, and the sand that strong wind is carried under one's arms then is blocked in before the grass net.Straw checkerboard barrier and careless fence have a shortcoming, are exactly the life-span weak point, damage easily.

2. flush system sand-protecting barrier: utilize faggot, stalk, cobble, clay etc. comprehensively or band shape be tiled in husky table.Isolated wind contacts with husky table, though cause wind to cross and the effect of Sha Buqi.The tiling of grass straw can reach the original place tackling quicksand, the effect of protective plant growth.And dust storm evil area, wide vastness with type things such as stalks, is that lid is unequal to lid, separated at a distance from being unequal to, this has determined the humble of its total effect of defending and controlling sand.

3. vertical sand barrier: be divided into high vertical, low vertical.High vertical sand barrier: adopt high culm plant, directly lining out is on sand like reed, shrub branch, cornstalk and jowar stalk etc., and the degree of depth of imbedding in the sand bed is 30-50cm; Expose height more than 1 meter; Or these materials are weaved into the basketry piece, and nail is on wooden frame, and it is husky with choked flow to form high vertical sand barrier.Low vertical sand barrier: exceed Shamian Island 20-50cm, this type of also claims half concealed type sand-protecting barrier, the obstruction that manufacturing materials is made with straw, straw, soft stalk weeds etc.This kind mode is little to the grains of sand interception in the stream.

In preventing and fixing sand prior aries such as straw checkerboard barrier, flush system, high vertical, low vertical sand barrier, material therefor mainly is a vegetable matter, like stalk, wormwood, brush wood etc.; Both very easily addled; Application life is extremely short, and is regional in the dust storm evil because of these materials again, and the one, total amount is limited; The 2nd, the dust storm area just was starved of these plants originally, and can't large tracts of land use.Cut as cut in a large number, be used to build sand-protecting barrier, both can't satisfy the demand because of measuring less, more be as good as to cut the flesh to cure a boil.

Therefore, be necessary to provide a kind of improved sand-protecting barrier setting to overcome above-mentioned defective.
