Abstract

The utility model aims to provide a herringbone 8-shaped cylinder mould sand barrier, which has low cost, does not pollute environment and can produce mechanically, and belongs to the engineering field. The herringbone 8-shaped cylinder mould sand barrier is formed through combining herringbone supports and a cylinder mould surface which is fixed on the herringbone supports through fixing holding strips, and the cylinder mould surface is fixed with a herringbone support spacing in 50cm, thereby forming the herringbone 8-shaped cylinder mould sand barrier.

Description

The herringbone fashion splayed net cage sand barrier

Technical field

The utility model relates to field of engineering technology, is specially a kind of herringbone fashion splayed net cage sand barrier.

Background technology

At present, the mechanical sand barrier of using in the desert treatment engineering mainly is with bavin, grass, straw, branch, cobble, clay and plastic wire etc. various forms of obstructions to be set on the desert to come sediment trapping to fix the sand.In the desertification regions of arid, because the plant seedling can't be grown up, often cause the ecological recovery failure in drift sand, therefore, need not the water mechanical sand barrier of tackling quicksand fast, status in sand control and effect are extremely important.The existing mechanical sand-protecting barrier is divided into three major types: a class is the flush system sand-protecting barrier, and a class is half concealed type sand-protecting barrier, and a class is the vertical type sand-protecting barrier; Flush system sand-protecting barrier and half concealed type sand-protecting barrier will be laid blind comprehensively on the desert, so consumable quantity is big, the cost height, therefore can not be in sand control engineering large-scale application, and flush system sand-protecting barrier and half hidden sand-protecting barrier can only fix the sand the part, can not tackle the desert drift sand; Existing vertical type sand-protecting barrier, reason owing to technology, can only be as the alternative of shrub, the sediment trapping function only rest on as planted one row bushes effect, reason is that existing technology can't be constructed the vertical type sand-protecting barrier on the dune ridge line of top of sand dune, can not use the sand dune as sand-protecting barrier, because on the dune ridge line, having stablized of vertical type sand-protecting barrier into big problem, very fast meeting is washed in a pan empty bottom by wind and is lodged; Present vertical type sand-protecting barrier is for the resistance that reduces wind and avoid being buried by drift sand, the sand-protecting barrier degree of porosity is mostly greater than 40%, take to allow drift sand pass through the mode of being detained again behind the vertical type sand-protecting barrier, when drift sand moves to the distance of leaving 20 times of sand-protecting barrier height, sand-protecting barrier just loses the function to its delay, if no longer establish sand-protecting barrier one, drift sand can drive straight in again, if construction is gone down together, not only drift sand still is in runaway condition, and cost is also very high.

Summary of the invention

The utility model aim to provide a kind of simple in structure, cost is low, the herringbone fashion splayed net cage sand barrier of easy construction, use the utility model herringbone fashion splayed net cage sand barrier of on the desert, constructing, by promoting the cylinder mould sand-protecting barrier drift sand interception in desert is piled into sand bar under cylinder mould, reach the fixing desert of flowing, stop the purpose of desert expansion.The utility model is to be 2009201624083 to the patent No., and patent name is the special project application of " splayed net cage sand barrier and constructing structure thereof " (my application) for the herringbone fashion splayed net cage sand barrier.

The utility model herringbone fashion splayed net cage sand barrier is combined by herringbone fashion support and the cylinder mould face that is fixed on the herringbone fashion support by fixed clamping bar, the cylinder mould face is that degree of porosity is between 10% to 30%, the plastic wire of wide cut between 15cm to 40cm, the degree of porosity of cylinder mould face and wide cut can be selected in above-mentioned scope as required.The herringbone fashion support is to prop up top of the trellis in splayed to extend 5cm to 10cm vertically upward and constitute upper frame, formation is configured to the herringbone fashion support of coupled integral body after by upper frame, splayed side arm and splayed, the height of herringbone fashion support can be selected between 15cm to 35cm, angle between side arm and the after-frame, had both been considered to put and surely has been convenient to again promote from sand drift greater than 35 ° of angles less than 75 ° of angles.The splayed side arm is identical with shelf structure after the splayed, can claim side arm and after-frame arbitrarily, and for increasing flexural strength, the cross section of side arm and after-frame can be made into T font, the multiple shape of L font.The cylinder mould face is fixedly clamped above the cylinder mould face on upper frame, side arm and after-frame by fixed clamping bar, and interval 50cm puts a herringbone on the cylinder mould face, constitutes the herringbone fashion splayed net cage sand barrier.

The length of single herringbone fashion splayed net cage sand barrier can be selected between 3m to 30m as required, and special circumstances sand-protecting barrier length can be less than 3m with greater than 30m.When on the desert, constructing, single herringbone fashion splayed net cage sand barrier upper frame is tightened the place that is placed on appointment up, the preceding base of herringbone fashion splayed net cage sand barrier contacts with base, back and desert are husky, the series connection of herringbone fashion splayed net cage sand barrier left and right directions is extended one by one, heap buries the thick desert sand of 5cm to 15cm on the base of cylinder mould sand-protecting barrier simultaneously, the warp of the cylinder mould face that is buried by sand drift since with the friction and the husky weight of sand drift, naturally become very heavy one by one bob, parallel becomes a rule span rope, and the herringbone fashion splayed net cage sand barrier has just been constructed on the desert securely.When being blocked the sand drift that gets off, buries when only exposing the cylinder mould top local cylinder mould sand-protecting barrier, in time this place's cylinder mould sand-protecting barrier is raised up from sand drift, again by above-mentioned work progress construction, so constantly repeat construction, just heap is high gradually under the herringbone fashion splayed net cage sand barrier for the desert drift sand, constitutes check dam.

Description of drawings

Fig. 1 is the transversal cross-sectional schematic of a kind of herringbone fashion splayed net cage sand barrier of the utility model.

Fig. 2 looks schematic diagram for a kind of herringbone fashion splayed net cage sand barrier of the utility model master.

1 is the herringbone fashion splayed net cage sand barrier in the accompanying drawing, and 2 is upper frame, and 3 is splayed side arm and splayed after-frame, and 4 is the cylinder mould face, and 5 is fixed clamping bar, and 6 is triradius, and 7 is the support apical ring.

The specific embodiment

Shown in accompanying drawing 1,2, herringbone fashion splayed net cage sand barrier 1 is combined by herringbone fashion support and the cylinder mould face 4 that is fixed on the herringbone fashion support by fixed clamping bar 5, and the herringbone fashion support is crossed at triradius 6 by upper frame 2, splayed side arm and splayed after-frame and makes herringbone fashion integral body.The splayed side arm is identical with shelf structure after the splayed, measure-alike, upper frame, splayed side arm and splayed after-frame are furnished with the fixed clamping bar 6 that shape, size are complementary with it, and cylinder mould face 4 is fixed on the centre of fixed clamping bar 6 and upper frame, splayed side arm and splayed after-frame.Interval 50cm fixes a herringbone cribbing on the cylinder mould face, constitutes the herringbone fashion splayed net cage sand barrier.The length of upper frame is selected between 5cm to 10cm as required, and greater than 35 ° of angles, select as required between 15cm to 35cm by the height of herringbone fashion support less than 75 ° of angles for the angle between side arm and the after-frame.

The utility model herringbone fashion splayed net cage sand barrier can be produced in enormous quantities with mechanization.
