Abstract

The utility model relates to the technical field of engineering, in particular to a saddle type splayed cage sand-protecting barrier. The saddle type splayed cage sand-protecting barrier is formed by combining a saddle type splayed bracket and a cage surface which is tensioned, attached and fixed on the splayed bracket, wherein the section of the cage surface is of a saddle type splayed shape after a single cage sand-protecting barrier is tensioned in left and right directions.

Description

The saddle type splayed net cage sand barrier

Technical field

The utility model relates to field of engineering technology, is specially a kind of saddle type 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 saddle type splayed net cage sand barrier of easy construction, use on the desert, the construct saddle type splayed net cage sand barrier of Great Wall style of the utility model, 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 saddle type splayed net cage sand barrier.

The utility model saddle type splayed net cage sand barrier is combined by saddle type splayed cylinder mould support and the cylinder mould face that is fixed on the cylinder mould support, the cylinder mould face is that degree of porosity is between 10% to 30%, the plastic wire of wide cut between 40cm to 100cm, the degree of porosity of cylinder mould face and wide cut can be selected in above-mentioned scope as required, and the wide cut of special circumstances cylinder mould face can be less than 40cm with greater than 100cm.Interval 50cm puts a saddle type splayed cylinder mould support below the cylinder mould face, the centre of cylinder mould face becomes the top margin of cylinder mould sand-protecting barrier, two limits of cylinder mould face become the preceding base and the base, back of cylinder mould sand-protecting barrier respectively, preceding base one side is identical with base, back one side structure, can choose wantonly during construction to be preceding base on one side.The two ends of splayed cylinder mould support intersect vertically with former and later two limits of cylinder mould face respectively, and the cylinder mould face is fixedly clamped on the cylinder mould support above the cylinder mould face by the fixed clamping bar that is complementary with the cylinder mould support.

The length of single saddle type 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, the place that is placed on appointment is tightened at single saddle type splayed net cage sand barrier top up, the preceding base of cylinder mould sand-protecting barrier contacts with base, back and desert are husky, the series connection of cylinder mould sand-protecting 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 saddle type splayed net cage sand barrier has just been constructed on the desert securely.Bury when only exposing the cylinder mould top when local cylinder mould sand-protecting barrier is blocked the sand drift that gets off, just in time this place cylinder mould sand-protecting barrier is raised up from sand drift, again by above-mentioned work progress construction, the desert drift sand is heap height gradually under the cylinder mould sand-protecting barrier just, the formation check dam.

The specific embodiment

Now 1,2 pair of the utility model is further described in conjunction with the accompanying drawings: saddle type splayed net cage sand barrier 1 is by saddle type splayed support 2 and tighten and adhere to the cylinder mould face 3 that is fixed on the splayed support 2 and combine, and the two ends of splayed support 2 intersect vertically with two limits of cylinder mould face respectively; Cylinder mould face 3 is fixedly clamped above the cylinder mould face on the splayed support by fixed clamping bar 4; The length of single saddle type splayed net cage sand barrier can be chosen wantonly between 3m to 30m, cylinder mould face 3 50cm is at interval fixed a splayed support 2, this can change adjustment at interval as required, after the tension of cylinder mould sand-protecting barrier left and right directions, the cross section of cylinder mould face is the saddle type splayed, and two limits of cylinder mould face become the cylinder mould base, front and back 5 of splayed net cage sand barrier; Preceding one side of something of saddle type splayed net cage sand barrier is identical with the half of structure in back, can choose one side preceding one side of something as the cylinder mould sand-protecting barrier during construction wantonly.

Now 3 pairs of the utility model are further described in conjunction with the accompanying drawings: the place that is positioned over appointment is tightened at single saddle type splayed net cage sand barrier 1 top up, the preceding base of cylinder mould sand-protecting barrier contacts with base, back and desert are husky, the series connection of saddle type splayed net cage sand barrier left and right directions is extended one by one, heap buries the thick desert sand 6 of 5cm to 15cm on the base of cylinder mould sand-protecting barrier simultaneously, and the saddle type splayed net cage sand barrier has just been constructed on the desert securely.

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