Abstract
The invention relates to a tying and placing method for a vertical sand barrier, which adopts a nonuniform structure, namely, the porosity or ventilation coefficients at the upper part and the lower part are different; the sand barrier is layered in the vertical direction; and the lower structure is compact, the middle structure is sparse, and the upper structure is ventilative. The high vertical structure tied and placed through adopting the method adapts to the vertical distribution of concentration of wind-drift sand, thereby not only effectively withholding the sand delivery of wind-drift sand, but also reducing the wind pressure on the sand barrier, reducing the breakage damage of wind power, meanwhile reducing the material consumption and sand-prevention cost; and the method provided by the invention can be applied in the mechanical sand-prevention engineering at all areas with sand storms.
Description
Technical field
The present invention relates to a kind of construction method of sediment control structure, be specifically related to a kind of bundle equipment, method of vertical sand barrier.
Background technology
Sandstorm not only affects arid and semi-arid regions, but also can involve other regions, has become global disaster.Sandstorm control a kind of important technological means be that engineering sand control measure is set, by " solid, hinder, defeated, lead " etc. effect, reach the object of sand-proof sand control.Hindering husky measure is a kind of important engineering sand control measure, is the important component part of sand-prevention system.Sand prevention is short in needed material, cost is higher and labour cost is high, is the subject matter that Current mechanical sediment control structure faces, and limits the extensive enforcement of sediment control structure.How effectively reducing the material cost of mechanical sand prevention, is the important thinking solving this problem.
Problems existing in building for above mechanical sediment control structure, the present invention intends changing the consistent homogeneous texture of vertical sand barrier, provides a kind of bundle equipment, method of vertical sand barrier of heterogeneous texture, reduces sand prevention cost by reducing sand prevention material usage.
Summary of the invention
The object of the invention is to, provide a kind of bundle equipment, method of vertical sand barrier, the vertical sand barrier that the method relates to is heterogeneous texture, i.e. upper and lower degree of porosity or coefficient of air infiltration difference.Adopt sand-protecting barrier is extremely lower and above divide band to arrange, substructure is tight type, and middle part is thin saturating type, and top is aeration type.Prick the vertical structure of establishing and stream concentration vertical by the method to distribute and adapt, effectively can not only tackle sand flow sediment transportation, and reduce the wind pressure on vertical sand barrier, alleviate wind-force breakage harm, also reduce material usage simultaneously, reduce sand prevention cost.The method of the invention can be applied in the mechanical sediment control structure of all wind sandy land.
The bundle equipment, method of a kind of vertical sand barrier of the present invention, relates to a kind of sand-protecting barrier of heterogeneous texture in the method, concrete operations follow these steps to carry out:
The making of a, sand-protecting barrier: straw is bundled into the grass of 2-5cm diameter (1), then grass is cut into (1) section of long 1-3m; Or be cut into the wide band of 10-60cm by the sand proof net (4) of three kinds of degree of porosity;
B, waiting lay earth's surface, sand-protecting barrier district, line determine sand-protecting barrier position, rule on spud pile (2) one end is imbedded in surface layer (3), length of embedment 30-40cm, the spacing of spud pile (2) is 1-6m;
C, the grass made by step a are put (1) or the earth's surface between sand proof net (4) band with two spud piles parallel, be fixed on spud pile (2), form sand-protecting barrier, the lower floor of sand-protecting barrier is tight band (5), the middle level of sand-protecting barrier is for dredging saturating band (6), and the upper strata of sand-protecting barrier is ventilation band (7).
Step b is when burying spud pile (2) underground, and fixing grass is 1.0-1.5m the spacing of the spud pile of (1) (2), and the spacing of the spud pile (2) of fixing sand proof net (4) is 3-6m.
The grass made in step c is 5-8mm the spacing of the tight band of (1) sand-protecting barrier lower floor (5), and the spacing that band (6) is dredged in sand-protecting barrier middle level is 8-15mm, and the spacing of sand-protecting barrier upper strata ventilation band (7) is 15-20mm.
In step c, the degree of porosity of the tight band of sand proof net (4) sand-protecting barrier lower floor (5) is 10%-30%, the degree of porosity that band (6) is dredged in middle level is 30%-45%, the degree of porosity of upper strata ventilation band (7) is 45%-60%, and three kinds of bands are woven to one or on-the-spot laying, splice and fix.
In step c sand proof net (4) three kinds of degree of porosity bands be arranged as overlapping 1-2cm between each band.
The arrangement mode forming the three types componental banding of sand-protecting barrier in step c is: three layers of arrangement of band (6) and upper strata ventilation band (7) are dredged in the tight band of lower floor (5), middle level, or the two-layer arrangement of the tight band of lower floor (5) and upper strata ventilation band (7) or be alternately arranged, or being alternately arranged of band (6) and upper strata ventilation band (7) is dredged in the tight band of lower floor (5), middle level.
The bundle equipment, method of a kind of vertical sand barrier of the present invention, the design philosophy of the method is: when sand proof net degree of porosity within the specific limits time, its protective action difference is little; Sand proof net lower floor protective capacities is very large on its initial stage protection benefit impact; Before and after sand proof net after sand, its protection benefit is not only relevant with upper strata sand proof net degree of porosity, also relevant with sand volume morphing.Therefore, the high vertical sand barrier Structure Adjustment Thought of " grab down and put, density combines, and band combines " is defined.
The bundle equipment, method of a kind of vertical sand barrier of the present invention, main feature is: the high vertical sand barrier up-down structure that (1) relates to is uneven, is combined by the band of multiple different aperture degree; (2) lower floor's band of the vertical sand barrier related to adopts comparatively dense structure, and upper strata adopts comparatively sparseness structure, and the width of each sand-protecting barrier is identical or different.The vertical sand barrier that this invention relates to changes the consistent tone patterns of up-down structure in the past, can save sand prevention material, reduce cost, be convenient to apply on a large scale; The band that degree of porosity is larger is simultaneously convenient to air-flow and is passed through, and sand-protecting barrier blast reduces, and alleviates wind-force breakage.
By showing in Vegetation in Center of Taklimakan Desert experimental data, the heterogeneous texture vertical sand barrier that method of the present invention obtains has played good benefit of checking winds and fixing drifting sand.
