Its advantages include use of solar energy to save energy resource, manpower resource and material resource, benefiting water and soil conservation and reducing environmental pollution.
Description
The present invention relates to a kind of method and device thereof of administering the desert and building highway.
In existing highway road building technology, road building machinery is for general on the roadbed and lays, smooth or compacting road materials.And the materials such as normally soil, lime, sandstone, pitch and cement of road surface pavement.There is following deficiency usually in the highway of Xiu Zhuing in this way: the soil property road surface is loose, is easy to generate mire, the dust of kicking up, and is the easiest damage; The gravel road surface rough surface, the tire of fragile vehicle also jolts the vehicle generation; Flexible pavement is smooth smooth, but non-refractory and severe cold; With the rigid pavement that sandstone and cement are built, the quality height, but its cost is high.Because the manufacturing of cement will expend a large amount of energy.Particularly build such highway in the desert area of vastness, its cost is immeasurable especially.And aspect existing control of desert, controlling sediment by plant and engineering sand control two classes are arranged.Engineering sand control mainly is to place obstacles or the method for covering resistance sand fixes the sand with faggot, clay, seat basketry or other high molecular polymer etc.Chinese patent application prospectus (publication number CN1065112A) has description to this, and the method that discloses a kind of petrochemical industry sand-fixed dust-proof, built the road and build the room.This manual proposes a kind ofly to utilize the chemical bond effect to make the husky petrochemical industry rapidly in desert, and so as to the tackling quicksand and the method for building sandy highway, that this method has is lower than in the past engineering sand control expense, than the advantage of in the past controlling sediment by plant instant effect.But because will be on husky body the spraying liquid chemical raw material, still need pay great cost so implement to spray, and can be subjected to the restriction of raw material resources in vast desert area.
The objective of the invention is: seek a kind of grains of sand or soil of can making and carry out petrochemical industry, do not use the method for any proprietary material again.Use this method to gather materials on the spot, administer the desert and build highway.
As everyone knows, the rock that tellurian magma cooling back forms, earth's crust transition and efflorescence through millions upon millions of years have just formed present Gobi desert, desert and soil.Solable matter major part in the original rocks is separated by water-soluble, enters ocean and lake.Grains of sand main component in most of soil and the desert is the various silicate that are insoluble in water.We know that the soil and the grains of sand at high temperature can be sintered into brick, if temperature further improves, make it become cooling again behind the liquid, then can make it to become rock again.This artificial rock is compared with the rock before the weathering, because the minimizing of solable matter can stand the weathering of longer time.Obtain this artificial rock, the method that adopts fuel to heat for administering the desert, obviously is unpractical.The present invention proposes a kind of inexhaustible solar energy that utilizes, and soil or desert are heated, and makes it method and a kind of device of petrochemical industry.Utilize this method and device that desert surface is carried out the construction of petrochemical industry covering and desert highway, can greatly save the raw material and the energy.
Principle of the present invention is: sunshine is focused on, make it to become high-energy light beam guiding.This light beam irradiates on the ground, the temperature that illuminated place is produced is enough to the fusion grains of sand or soil, makes the grains of sand or soil become liquid state or with its sintering.With beam flying ground, the ground of light beam immigration place constantly is heated fusing, and light beam shifts out the continuous cooled and solidified in place.With the building highway on desert is example, is an arrowband if be incident upon ground high-energy light beam guiding, and its length equals width of roadway, and the direction mobile beam that only need advance along the road surface this moment can make the road surface form a hard slabstone; If the light beam of throwing on the ground is a round dot, need carry out light beam the transversal scanning perpendicular to the road surface direct of travel this moment, after having scanned delegation, device carries out flyback after moving a step pitch with step-by-step system forward along the highway direct of travel again, after flyback finishes, step further again, so repeatedly, make beam flying cross whole road surface, the road surface then forms the hard slabstone of one deck.After this, on this layer slabstone, lay the grains of sand or soil repeatedly, carry out illumination repeatedly, the slabstone on road surface is constantly thickeied, thereby build out a flagstone path.In like manner, for the covering in desert, then need not to carry out illumination repeatedly, only Bao one deck stone face is just enough.For the coverage rate in desert, open some at regular intervals not by the zone of illumination, be used for the seepage of rainwater.
Advantage of the present invention is: compare with road building technology with existing sand control, because utilize solar energy, gather materials on the spot, so can save a large amount of energy, road materials and human and material resources.When having reduced energy consumption, also just reduced environment pollution.Especially in desert area, sunlight is strong, and less rainy weather utilizes sand control of the present invention and builds highway, and will produce huge economic benefit and social benefit.This desert coverage rate can reduce phreatic evaporation greatly, helps the retaining in desert.Use method of the present invention, can also be used to that reservoir bottom of the reservior, water-drawing channel are carried out antiseepage and handle.
To the road surface, there is transmission-type to focus on and two kinds of methods of reflective focusing solar light focusing.Transmission-type focus on to need is made large-scale collector lens, cost height not only, and make, transportation is also very difficult; The concave mirror that the metal sheet that reflective focusing use is coated with reflectorized material is made, these concave mirrors are made easily and are assembled into large-area reflector easily, are a kind of best choice.Solar light focusing can be become an arrowband with the cylindrical concave mirror, solar light focusing can be become a round dot with the rotation concave mirror.Make solar light focusing become a round dot more more concentrated than the energy that is focused into an arrowband, the light beam that reflexes on the road surface can make the road surface produce higher temperature, and therefore adopting the rotation concave mirror that sunshine is focused on also is best selection.
The sand control that designs according to principle of the present invention and optimal selection, build the road device as shown in Figure 1, it by control system 1, dynamical system 2, frame 3, track 4, scanning car 5, sun azimuth tracking system 6, focus on Adjustment System 7, rotational paraboloid mirror 8, ellipse of revolution face speculum 9 and guard system 10 and formed.
