Description
Technical field
The present invention relates to sand control engineering technical field, the construction knot that bag sand-protecting barrier, segmentation sand-protecting barrier are combined with plantation is specially hanged
Structure.
Background technology
At present, in desert treatment, net grid sand-protecting barrier, sandbag sand-protecting barrier, straw checkerboard barrier sand-protecting barrier is widely used and implements convection current
The fixation in dynamic desert, then plants psammophytes on the desert secured.Due to setting the straw transportation cost of straw checkerboard barrier very
Height, construction cost is also very high, and stalk straw checkerboard barrier will lose function of fixing the sand in 3 years because of weathering corrosion, makes the plant weight planted
Newly face by the condition of dust storm erosion；Net grid and sandbag sand-protecting barrier unit area building cost are more much higher than straw checkerboard barrier sand-protecting barrier, are big faces
The financial burden that product sand control engineering can not be born.The method that a kind of husky ridge of U-shaped Sand-fixation net is fixed the sand, U-shaped are provided before applicant
Sand-fixation net sand ridge sand-fixing effect is good, and cost is also reduced than net grid sand-protecting barrier, but because the section of U-shaped Sand-fixation net takes the shape of the letter U,
Construction is cumbersome, there is also the phenomenon being turned in moving dunes windward slope by eroding.Therefore, invent a kind of outstanding bag sand-protecting barrier,
The constructing structure that segmentation sand-protecting barrier is combined with plantation, to overcome the defect of above-mentioned sand-protecting barrier, the need for being control of desert.
The content of the invention
The technical problem to be solved in the present invention and the technical assignment proposed are to overcome the defect of prior art outstanding there is provided one kind
The constructing structure that bag sand-protecting barrier, segmentation sand-protecting barrier are combined with plantation.The constructing structure that outstanding bag sand-protecting barrier, segmentation sand-protecting barrier are combined with plantation, be
Decomposite what is come according to the principle of " sand-protecting barrier be combined at the top of the landforms of desert sediment trappings fix the sand function law ", " sand-protecting barrier and desert
Sediment trappings are combined at the top of looks to fix the sand function law " character express be：" put at desert landforms (moving dunes, longitudinal dune, Sha Geng)
The sand-protecting barrier at top, the function with fixed flowing desert, the size of function, equal to 1.42 times, the height of desert landforms adds sand
Square of sand-protecting barrier height sum at the top of unconcerned landforms, is multiplied by the length of sand-protecting barrier on contour at the top of the landforms of desert." its formulation
It is：
V=1.42 (H1+H2)2L
V is amount of drift sand in formula, and H1 is the height of desert landforms (moving dunes, sand bar, Sha Geng), and H2 is at the top of the landforms of desert
The height of sand-protecting barrier, L is the length of sand-protecting barrier on contour at the top of the landforms of desert.
1.42 data in formula, are to constitute flowing according to the gradient angle of repose (maximum angle of repose is 35 ° of angles) of moving dunes
What the area statistics of sand dune section triangle were drawn, when moving dunes are (including recessed in longitudinal dune, Sha Geng, Sha Kan, grid sand-protecting barrier
Face) domatic somewhere, angle be more than angle of repose when, sand will be collapsed downwards, collapse to the gradient be less than angle of repose place, just from
So stop collapsing.
Straw checkerboard barrier sand-protecting barrier and sandbag grid sand-protecting barrier on desert fix the sand building site, one can see that sand-protecting barrier grid one by one
It is interior, it is the sand pit being recessed down one by one.The size of straw checkerboard barrier sand-protecting barrier it is general in 1m × 1m between 1.5m × 1.5m, strong wind
My god, the desert that strong wind punching is washed in a pan away in the sand in straw checkerboard barrier, straw checkerboard barrier will be recessed down, when the domatic gradient in straw checkerboard barrier is more than
Angle of repose, domatic to collapse, the sand under straw checkerboard barrier will be collapsed to the pit in straw checkerboard barrier sand-protecting barrier, in some dusts storm mouthful, when
The Desert Sand of straw checkerboard barrier inside recess, is washed in a pan away, the sand under straw checkerboard barrier sand-protecting barrier, just the pit constantly into straw checkerboard barrier sand-protecting barrier by continuous punching
Collapse, once the sand below straw checkerboard barrier sand-protecting barrier is by naughty sky, straw checkerboard barrier sand-protecting barrier just disintegrates.This phenomenon is being provided with straw checkerboard barrier sand
Hinder the dust storm mouthful in building site, be very common.Such phenomenon is fixed the sand building site in sandbag grid sand-protecting barrier, shows more prominent, former
It is bigger than straw checkerboard barrier because being the specification of sandbag grid sand-protecting barrier, typically in 1.5m × 1.5m between 2m × 2m, strong wind day sandbag grid
Pit in sand-protecting barrier, can firmly get many, the sandbag grid sand-protecting barrier on the windward slope of desert, strong wind than the pit in straw checkerboard barrier sand-protecting barrier
It is washed in a pan away due to husky constantly rushed by strong wind in sandbag grid, and the sand below sandbag sand-protecting barrier just constantly collapses to the pit of sandbag grid
Fall into, sandbag is fallen into hole therewith, and sandbag dune work just becomes in disorder.
, can according to " sand-protecting barrier be combined at the top of the landforms of desert sediment trappings fix the sand function law " and the angle number that stops on sand dune
To calculate：Pit in 2m × 2m grid sand-protecting barriers, depth about 60cm.Pit in 1m × 1m grid sand-protecting barriers, depth about 30cm,
Pit in 0.5m × 0.5m grid sand-protecting barriers, depth about 15cm.To desert fix the sand building-site detection, conclusion is also what is be consistent.
As can be seen here, the interval between sand-protecting barrier is smaller, by erosion into pit Yue , the foundation of sand-protecting barrier is more firm.Therefore, U is worked as
The spacing on the shape Sand-fixation net sand ridge, during more than 1m, especially in windward slope, can equally be collapsed by erosion.If reducing U-shaped Sand-fixation net
The spacing on the husky ridge, must increase engineering cost, therefore, manufacture experimently miscellaneous new sand-protecting barrier, to reduce construction costs, improve engineering
Quality, is the routine work of applicant these years.
By month after month being contrasted on desert to various sand-protecting barrier repetition tests throughout the year, it has been found that wide cut 17cm, long 3m
Vertical insert of Sand-fixation net horizontal direction to 10m is embedded on the windward slope of moving dunes, and strong wind day, Sand-fixation net is rushed by strong wind soon
Wash in a pan out, included away by wind.Identical wide cut, long 12cm fillet Sand-fixation net, horizontal direction is vertically inserted and is embedded in meeting for moving dunes
On wind slope, strong wind, but see that fillet Sand-fixation net is safe and sound several times is undergone, the Desert Sand on fillet Sand-fixation net periphery is walked by strong wind erosion
, top of the top margin as a sand hill of fillet Sand-fixation net, this fillet Sand-fixation net not only ensure that inherently safe, also fixed
Desert Sand one small sand hill of formation around firmly.This is an of great value discovery, and this finds explanation potting on desert
Sand-fixation net, length is longer, is more subject to wind erosion and includes race by strong wind, the fillet Sand-fixation net for being about 12cm is just very safe.According to
This finds that people can be Sand-fixation net cutting into the fillet that length is 12cm, the parallel direction interval 10cm to 12cm on desert
