Description
Technical field
The present invention relates to a kind of clay-based sand-protecting barrier, more particularly to a kind of combined clay-based sand-protecting barrier for being easy to mechanical work,
Belong to the water and soil conservation field for aspect of checking winds and fixing drifting sand.
Background technology
Loess Plateau place threatened by wind and sand is predominantly located to the north of Along The Great Wall, and south is wreaked havoc in the Yinshan Mountains with dust storm, Helan Mountain with
East, to the west of Shuozhou City, the line of Huhehaote one, based on Erdos dust storm plateau, about 200,000 square kilometres of area, account for complete
The 1/3 of area's area.Desertification land area accounts for the 57% of the Wind-sandy Area gross area up to 11.8 ten thousand square kilometres in Wind-sandy Area.Sternly
Weight desertification area is about 3.6 ten thousand square kilometres, predominantly Mu Us Shadi, Ku Buqi deserts and Sandy Land（Refer to Yellow River in Ningxia
Section east）, account for the 17.4% of the Wind-sandy Area gross area.In Wind-sandy Area, only dust storm aggrade enters yellow sand amount i.e. up to 1.6 hundred million tons, accounts for
The 1/10 of the Yellow River annual sediment discharge.In addition, place threatened by wind and sand also includes the area that desert edge influences the production of oasis resident living, such as
The Hexi Corridor area etc. of Tengger desert, Kumtag Desert edge.
Set sand-protecting barrier technology be according to different sand dune features set sand proof net, the husky wall of resistance, sand fence, straw checkerboard barrier sand-protecting barrier,
Clay sand-protecting barrier, hedge sand-protecting barrier etc., some fine and close membranoid substance or vegetative protection woodss are covered on sand dune, and then check winds and fix drifting sand
Purpose.Main suitable place threatened by wind and sand moving dunes region.Sand-protecting barrier can substantially reduce wind speed, cause near surface Structure of wind-Sand Flow to be sent out
Changing；Sand-protecting barrier can significantly improve nutrient density in 60 cm soil.
Clay-based sand-protecting barrier, check winds and fix drifting sand and continue long, clay skinning can not only reduce sandy soil surface temperature, and can provide one
To support needed for a little plant growths, promoting vegetation growth, arrival dust storm is fixed, the purpose of ecological management, therefore in loess plateau
Place threatened by wind and sand is widely used.At present, the typing of clay-based sand-protecting barrier also compares more, such as pattern, round.But
It is that these sand-protecting barriers are combined setting, the application for shunting, stopping, fix dust storm movement is more rare.
The content of the invention
It is an object of the invention to provide a kind of combined clay-based sand-protecting barrier, to change landforms type shape, shunting, stops, persistently
Fixed dust storm movement, promotes vegetation growth, realizes ecological management.
The clay-based combination sand-protecting barrier of the present invention, is to set gradually several layers of chevron shaped sand-protecting barrier, round sand-protecting barrier, grid along prevailing wind direction
Type sand-protecting barrier.
The length of side of chevron shaped sand-protecting barrier is 2m, wide 0.4 ~ 0.6m, high 0.3 ~ 0.4m；Line-spacing is 2m, is arranged away from for 2m.Sand-protecting barrier is set
The number of plies is put to be designed according to dust storm size and operating condition.Generally 3 ~ 20 layers, and each interlayer is staggered.
Round sand-protecting barrier is circular ring type, semi-annular or steamed bun type, and it is 3 ~ 20 layers to set the number of plies.Wherein, outside circular ring type sand-protecting barrier
Ring diameter 2m, 1 ~ 1.5m of annular diameters, the high 0.3 ~ 0.4m of ring；Spacing is 2m, and each interlayer is staggered.Semi-annular sand-protecting barrier
Anchor ring is windward to setting；Semicircular ring outer annular diameter 2m, 1 ~ 1.5m of annular diameters, the high 0.3 ~ 0.4m of ring；Spacing is 2m, and each layer
Between be staggered.The base diameter of steamed bun type sand-protecting barrier is 2m, high 0.8 ~ 1.2m, and each interlayer is staggered.
Pattern sand-protecting barrier is set in flakes for square, outer length of side 2m, interior 1 ~ 1.5m of the length of side, high 0.3 ~ 0.4m.
Chevron shaped clay-based sand-protecting barrier stops that shunting is obvious, is adapted to stream rapidly to stop distinguished and admirable；Circular ring type clay-based sand-protecting barrier
Catch blowing sand stream is relatively slow, is suitable for delaying to shunt reduction of speed again；Pattern clay-based sand-protecting barrier is primarily to stop fixed shunting
Dust storm, reach final stable and tackling quicksand purpose.Chevron shaped-circular ring type-pattern combination clay-based sand-protecting barrier is step by step
Dust storm flow velocity is reduced, reaches the effect of fixed dust storm movement.
Brief description of the drawings
Fig. 1 is that chevron shaped/circular ring type/pattern clay-based combines sand-protecting barrier schematic diagram.
Fig. 2 is that Dunhuang Yanguan Pass carries out mechanization setting clay-based combination sand-protecting barrier desert improvement effect using loading machine.
Embodiment
In order to further illustrate the effect of the setting of the combined clay-based sand-protecting barrier of the present invention and desert improvement, we are in Dunhuang Yanguan Pass
Area carries out mechanization using loading machine and combines sand-protecting barrier there is provided chevron shaped-circular ring type-pattern clay-based to be administered, and right
Regulation effect is evaluated.
Clay-based combines the setting of sand-protecting barrier：3 ~ 20 layers of chevron shaped sand-protecting barrier are first set along prevailing wind direction, then set 3 ~ 20 layers it is round
Sand-protecting barrier, it is rear that pattern sand-protecting barrier in flakes is set, as shown in Figure 1.
Chevron shaped sand-protecting barrier：Two length of sides are 2m, hem width 0.5m, high 0.35m, and away from being 2m, each interlayer interlocks cloth row, column
Put.
Circular sand-protecting barrier：It is high to setting, outer annular diameter 2m, annular diameters 1m, ring windward for semi-annular, the one side of circular ring type
0.35m, distance is 2m between circular ring type sand-protecting barrier.
Circular sand-protecting barrier can also use circular ring type or steamed bun type, and layout straggly.The outer annular diameter 2m of circular ring type sand-protecting barrier, it is interior
Ring diameter 1m, the high 0.35m of ring, distance is that 2m row, column distances are 2m between circular ring type sand-protecting barrier.The bottom of steamed bun type sand-protecting barrier is straight
Footpath 2m, high 1m, layout are consistent with circular ring type.
Pattern sand-protecting barrier：Square lattice, connect and set in flakes.The outer length of side 2m of square lattice, interior length of side 1m are high by 0.35
m。
For the ease of the plantation of psammophytes, a layer thickness 0.1m clay etc. is covered with sand-protecting barrier top layer.
Various sand-protecting barriers are standardized, in order to realize the quick, efficient, inexpensive of the mechanical work of clay-based combination sand-protecting barrier
Setting.
