Abstract
The utility model relates to a sand protecting and guiding fence, which is structurally characterized in that the fence is an inverse V-shaped nylon net fence; and two linear parallel transverse fences are arranged in the inverse V shape, so as to form an A-shaped fence. The height of the fence is 1.8m, the porosity factor is 20 percent, the resistance coefficient is 1.5, angle iron No.45 is adopted as an upright post during the construction of the fence, the spacing is 3m, a cement block of 20cm*30cm*60cm is poured at the lower end of the upright post and is embedded in the ground, a wire rope is pulled and reinforced on a nylon net frame in an inclined manner, and the angle of the wire rope is 45 degrees. The sand protecting and guiding fence can cut off sand sources in the secondary prevailing wind direction, can also achieve the sand guiding function in the prevailing wind direction, and changes the only single function of the conventional fence for cutting off sands. About 60 percent is reduced compared with the monthly sand accumulation before the fence is not mounted. The sand protecting and guiding fence plays an important role of stabilizing gravel earth surfaces and protecting rock caves and murals.
Description
Technical field
The utility model relates to a kind of Gobi desert dust storm control training for sediment fence that is used for.
Background technology
The Mo kao grotto at Dunhuang have the title of " museum on the wall ", " world's art gallery ", and top, cave Mingsha Sand Dunes are a tall and big husky mountain, and Sha Yuan is abundant, and wind-sand activity is strong.The Mogao Grottoes has experienced more than 1600 year so far from creating, and rock cave, mural painting all have been subjected to the damage of dust storm to some extent.On the one hand, seriously long-pending sand causes plank road long-pending husky, and grottoes bury; The sand and dust material is quite serious to the abrasion of mural painting, statue on the other hand, grottoes cup and the therefore a large amount of shank colors of open-air mural painting, even large tracts of land comes off.Dust storm has caused people's attention to the harm of Mogao Grottoes when five generations, and husky clearly record is arranged.Play historical relic research institute the 1950's just the important process of sand prevention as the rock cave protection.At the beginning of the sixties, worked out sand prevention planning, carried out the small-scale test of defending and controlling sand simultaneously, on sheer, build sand-proof wall, take stifled clear down " method, but after because of amount of drift sand is big, cause body of wall to cave in, jeopardize the cave district, be forced to dismounting.Again at the anti-sand furrow of sheer excavation, part red building bar fence is set subsequently, the result causes a large amount of sand materials to gather, and ditch is very fast to be filled and led up, and sand-protecting barrier is buried by pressure, forms new hidden danger.
Summary of the invention
Avoid hazards of sand storms in order to ensure the Mogao Grottoes, the utility model purpose is to provide a kind of sand prevention, training for sediment fence.Sand prevention, training for sediment fence are " A " font nylon wire fence.Sand prevention effect result for many years shows that " A " font nylon wire fence sand prevention system has played the control drift sand on top, cave, Mogao Grottoes, stablized the important function of grit quality table and protection rock cave and mural painting.It has not only expanded the range of application of fence, and provides successful experience for the control of grit matter Gobi desert stream.
The purpose of this utility model is to realize by following measure:
A kind of sand prevention, training for sediment fence, fence are " Λ " shape nylon wire fence, in " Λ " shape, two " one " font parallel transverse fence are set, and are " A " font.The high 1.8m of fence, porosity is 20%, and resistance coefficient is 1.5, and fence adopts 45 bugle steel as column, and spacing is 3m, the clump of column lower end casting 20cm * 30cm * 60cm is embedded in undergroundly, and has 45 ° of wire rope inclined-pullings to reinforce on the nylon wire framework.
The beneficial effect of advantage of the present utility model and generation is:
Be the Gobi desert, have the ambient conditions of multichannel wind direction that the environment that it is the Gobi desert that the technical solution of the utility model is based on urban conservation area, top, cave, Mogao Grottoes, have a multichannel wind direction produces at urban conservation area, cave, Mogao Grottoes top:
(a) " Λ " shape nylon wire fence is on Gobi desert, top, cave, the characteristics that have 3 groups of stable wind directions according to the Mogao Grottoes, design, implemented the nylon wire anti-sand fence of " Λ " font, prevailing wind direction is pointed on " Λ " font summit, its purpose can be blocked the husky source of Mingsha Sand Dunes on inferior wind direction, can on prevailing wind direction, make fence have the training for sediment function again, and change fence in the past only as the simple function of the husky effect of resistance.
(b), two " one " font parallel transverse fence in " Λ " font fence, being provided with, be mainly used in and stop the Gobi desert and play sand on the spot, and combine " A " font nylon wire fence with " Λ " shape nylon wire fence.
Sand prevention, training for sediment fence system are built up in urban conservation area, top, cave, Mogao Grottoes, and the husky moon border of measuring of the long-pending sandbox of contrast plank road changes, long-pending husky obvious minimizing of grottoes plank road.Compare with the long-pending sand in moon border before not establishing fence, approximately reduced about 60%.We can say: " A " font nylon wire fence has played the control drift sand on top, cave, Mogao Grottoes, has stablized the important function of grit quality table and protection rock cave and mural painting.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is Fig. 1 fence construction schematic diagram.
The specific embodiment
Shown in Fig. 1-2: a kind of sand prevention, training for sediment fence, fence are " Λ " shape nylon wire fence 1, in " Λ " shape, two " one " font parallel transverse fence are set, and are " A " shape fence.The high 1.8m of fence, porosity is 20%, resistance coefficient is 1.5, the fence construction adopts 45 bugle steel as column 2, and spacing is 3m, the clump 4 of column lower end casting 20cm * 30cm * 60cm, be embedded in undergroundly, and have 45 ° of wire rope 3 tiltedly to draw reinforcing on the nylon wire framework.In force, " A " font nylon wire fence is the characteristics according to wind direction.At first, prevailing wind direction should be pointed in " Λ " font summit, and its purpose can be blocked Sha Yuan on inferior wind direction, can make fence have the training for sediment function again on prevailing wind direction, and changes fence in the past only as the simple function of the husky effect of resistance.
Two two parallel transverse fence that " one " font parallel transverse fence is provided with in " Λ " font fence are mainly used in the obstruction Gobi desert and play sand on the spot, and combine " A " font nylon wire fence with " Λ " shape nylon wire fence.
The present invention suits measures to local conditions Gobi desert, top, cave, Mogao Grottoes dust storm has been carried out the comprehensive regulation.Facts have proved: " A " font nylon wire fence has played the control drift sand, has stablized the important function of grit quality table and protection rock cave and mural painting.It has not only expanded the range of application of fence, and provides successful experience for the important cultural relics and historic sites of control and China of grit matter Gobi desert stream and the protection of economic facility.
