Abstract

The utility model aims to provide a splayed net cage sand barrier and a construction structure thereof, and the splayed net cage sand barrier can intercept desert quicksand on sand ridges. The utility model aims to intercept and fix the quicksand of a flowing desert under the splayed net cage sand barrier, and achieves the purposes of fixing migratory dunes and preventing desert expansion. The splayed net cage sand barrier is formed through the combination of a front net cage sheet and a rear net cage sheet, the sections thereof are splayed and inclined; each of the net cage sheets is formed by a net cage surface and a plurality of support rods; and a plurality of splayed net cage sand barriers are arranged in the left-and-right sequence on the desert according to design routes, and can be extended continuously according to design lengths.

Description

Splayed net cage sand barrier and constructing structure thereof
Technical field
The utility model relates to field of engineering technology, is specially a kind of splayed net cage sand barrier and constructing structure thereof.
Background technology
At present, the mechanical sand barrier of using in the desert treatment engineering mainly is with bavin, grass, clay, branch, cobble, wicker and plastic wire etc., various forms of blinds is set on Shamian Island comes sediment trapping to fix the sand.At the desert edge of arid extremely, plant can't grow in drift sand, therefore, need not the mechanical sand barrier that water can tackling quicksand, and status in sand control and effect are extremely important.The existing mechanical sand-protecting barrier is divided into two big classes: a class is the flush system sand-protecting barrier, and a class is the vertical type sand-protecting barrier; The flush system sand-protecting barrier will be laid blind comprehensively on the desert, so consumable quantity is big, and cost is high, can't be in sand control engineering large-scale application; 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 a row bushes on the effect, existing technology can't be constructed the vertical type sand-protecting barrier on the dune ridge line of top of sand dune, because on the dune ridge line, the very fast meeting of vertical type sand-protecting barrier is washed in a pan empty because of the bottom by wind and is lodged; Can not all tackle the drift sand through the vertical type sand-protecting barrier live again, because if all interception is in the sand-protecting barrier both sides drift sand, the very fast meeting of vertical type sand-protecting barrier be buried by drift sand and is scrapped.Therefore, the vertical type sand-protecting barrier is mostly taked to allow drift sand flow away by sand-protecting barrier at present, only works to be detained drift sand.Therefore, designing a kind of interception desert drift sand of can constructing on the dune ridge line at moving dunes top, desert, can repeat to promote the vertical type sand-protecting barrier of tackling dust storm mouth desert drift sand in the construction of the lowest point, sand dune again, has been the needs of the times.
The utility model content
The utility model aims to provide a kind of splayed net cage sand barrier and the constructing structure thereof that can tackle the desert drift sand on the dune ridge line, purpose is by construction the utility model, the interception of the drift sand in the desert of flowing be fixed on splayed net cage sand barrier below, reach and fix moving dunes, stop the purpose of desert expansion.
The utility model is to be 200810100602.9 to application number, and denomination of invention is the special project application of " tandem sand trapping net cage and the check dam of constructing thereof " (my application) for splayed net cage sand barrier and constructing structure thereof.The utility model splay configuration cylinder mould sand-protecting barrier is combined by preceding cylinder mould sheet and back cylinder mould sheet, and the cross section of preceding cylinder mould sheet and back cylinder mould sheet becomes splayed to tilt, and the top margin of two cylinder mould sheets is parallel to be drawn close, the mutual correspondence of the support bar top on the cylinder mould sheet of front and back near.Preceding cylinder mould sheet is identical with length, width and the structure of back cylinder mould sheet, can exchange, and can be referred to as the cylinder mould sheet; The cylinder mould sheet by penetrating rate between 5% to 15%, the plastic silk screen of wide cut between 20cm to 50cm done the cylinder mould face, interval 40cm to 100cm is equipped with a support bar on the cylinder mould face, the top margin and the base of support bar and cylinder mould face are perpendicular, the tight cylinder mould face in the top of support bar, by connecting plate the cylinder mould face is fixed on the support bar, cylinder mould face base 5cm to 25cm is stretched out in the bottom of support bar, cylinder mould face and several support bar constitute the cylinder mould sheet, the width of cylinder mould sheet is optional between 20cm to 50cm, and length is optional as required between 2m to 50m.The left end support bar top of front and back cylinder mould sheet is equipped with a tightening buckle of connecting and fixing with adjacent cylinder mould sheet right-hand member support bar top, the right-hand member support bar top is equipped with a span rope that is used for stablizing the cylinder mould sand-protecting barrier, span rope is a thin plastic ties, length is 1.2 to 3 times of cylinder mould sheet width, the span rope other end is equipped with very heavy bob, and very heavy bob is the small wood of a length between 20cm to 30cm.
Many splayed net cage sand barriers are arranged in turn at upper edge, desert design route left and right directions, the cylinder mould sheet of each cylinder mould sand-protecting barrier is tightened about being, be plugged in the sand of desert to the lower tilt of support bar, the top of adjacent cylinder mould sheet right-hand member support bar is fixed in the tightening buckle series connection on cylinder mould sheet left end support bar top, front and back, and the base of front and back cylinder mould sheet embeds 1cm to 5cm in the sand of desert; The span rope at preceding cylinder mould sheet right-hand member top strides across back cylinder mould sheet, is strained and fixed by the very heavy bob that embeds in the sand of desert, cylinder mould back; The span rope at back cylinder mould sheet right-hand member top strides across preceding cylinder mould sheet, is strained and fixed by the very heavy bob that embeds in the sand of desert, cylinder mould front.
Under the wind-force effect, pasting the surperficial saltation in desert when the drift sand on the desert, be subjected to stopping of splayed net cage sand barrier, part drift sand is blocked in the cylinder mould underfooting, part drift sand bleeds inside the cylinder mould, part drift sand climbs over the cylinder mould top after the imperial face of net rises, spill to the sand dune of cylinder mould back waist with parabolical rule mark, sand dune and cylinder mould stop the turbulent flow that causes wind, the sand that falls is by the wind that refluxes to top of sand dune from sand dune leeward side bottom, blow back top of sand dune, drift sand is just piled up with the front and back of cylinder mould in cylinder mould, when drift sand is stacked into apart from cylinder mould top 1cm to 8cm, just untie the tightening buckle on cylinder mould left end top, untie the span rope on cylinder mould right-hand member top, cylinder mould sheet is one by one transferred to from sand drift, then heap high top of sand dune one line, from newly pressing above-mentioned constructing structure construction splayed net cage sand barrier, repeat to promote the cylinder mould sand-protecting barrier so again and again, just raise gradually on the sand dune, moving dunes make upwards heap height into from outwards flowing, the sand dune that heap is high makes splayed net cage sand barrier increase the function of sediment trapping again, thereby makes moving dunes become high check dam.
