Description
Technical field
The present invention relates to sand control engineering technical field, specially a kind of side for inserting embedding fillet Sand-fixation net construction camber line sand-protecting barrier
Method.
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, a kind of slotting embedding fillet is invented to consolidate
The method of sand net construction arc sand-protecting barrier, 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 that the defect for overcoming prior art is inserted there is provided one kind
The method of embedding fillet Sand-fixation net construction camber line sand-protecting barrier.Embedding fillet Sand-fixation net is inserted to construct the method for camber line sand-protecting barrier, be according to " sand-protecting barrier with
Sediment trappings are combined at the top of desert landforms to fix the sand function law " principle decomposite what is come, " sand-protecting barrier is mutually tied with desert landforms top
Sediment trappings are closed to fix the sand function law " character express be：" sand-protecting barrier at the top of desert landforms (moving dunes, longitudinal dune, Sha Geng) is put,
Function with fixed flowing desert, the size of function, equal to 1.42 times, the height of desert landforms is added at the top of the landforms of desert
Square of sand-protecting barrier height sum, is multiplied by the length of sand-protecting barrier on contour at the top of the landforms of desert." its formulation 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 exceed 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 exceedes
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
