Description

One buckles spliced sediment trapping net

Technical field

The utility model relates to sand control engineering technical field, is specially one and buckles spliced sediment trapping net.

Background technology

At present, in desert treatment, widely use plastic wire construction high vertical sediment trapping net, enforcement is to the interception in flowing desert and fix, but above-mentioned high vertical sediment trapping net due to vertical wire side when attacked by strong wind not only wire side easily blown brokenly, the wind stopped changes over upper and lower vertical direction from horizontal direction, and wind vertically downward can the sand of erosion sediment trapping sieve bottom, make sediment trapping sieve bottom unsettled, therefore construct just very unstable at the top of moving dunes and check dam.

Applicant is by for many years to the experimental construction that mechanical sand barrier sediment trapping fixes the sand, from the rule of observing desert flowing and the desert dynamic law occurred after landforms top, desert arranges sand-protecting barrier, draw " sand-protecting barrier to combine with landforms top, desert sediment trapping fix the sand function law ", its character express is: " put at desert landforms (moving dunes, sand bar, the husky ridge) sand-protecting barrier at top, there is the function in interception and fixing flowing desert, the size of function, equal 1.6 times of desert landforms (moving dunes, sand bar, the husky ridge) height add landforms top, desert sand-protecting barrier height sum square be multiplied by desert landforms (moving dunes, sand bar, the husky ridge) length of sand-protecting barrier on isohypse." its formulation is:

V＝1.6(H ₁+H ₂) ²S

In formula, V is the resistance sand amount of landforms top, desert sand-protecting barrier, H ₁for the height of desert landforms (moving dunes, sand bar, Sha Geng), H ₂for the height of landforms top, desert sand-protecting barrier.S is the length of sand-protecting barrier on the isohypse of landforms top, desert.

According to " sand-protecting barrier to combine with landforms top, desert sediment trapping fix the sand function law ", moving dunes are can by arranging sand-protecting barrier at top of sand dune, change the flow direction on sand dune, moving dunes are changed over tall and big check dam intercepting desert, the splayed net cage sand barrier of applicant's design is due to the defect of fracture between can not overcoming therefrom, within 10 years, fix moving dunes not success completely, until in 2013, " the outstanding bag shape high vertical sediment trapping net " of applicant's design has successfully fixed the dune ridge line at moving dunes top completely, and moving dunes from forward change over upwards pile high, harmful moving dunes have been changed over the check dam with intercepting desert function, demonstrate " sand-protecting barrier combine with landforms top, desert sediment trapping fix the sand function law " simultaneously and meet objective law.After gradually piling high dune ridge line heap buried outstanding bag shape high vertical sediment trapping net, just again need to construct on dune ridge line sediment trapping net, at this moment the outstanding bag shape high vertical sediment trapping net by heap buried to be raised up recycling not only very difficult, also can destroy dune ridge line, therefore the outstanding bag shape high vertical sediment trapping net having found a kind of utilization by heap buried, resetting one and buckle spliced sediment trapping net, has been the needs of control of desert.

Summary of the invention

The technical assignment of the technical problems to be solved in the utility model and proposition is the vacancy filling up prior art, buckle the construction of spliced sediment trapping net at the top of the outstanding bag shape high vertical sediment trapping net by drift sand heap buried a kind of, the outstanding bag shape sediment trapping net made by drift sand heap buried recovers sediment trapping function again.

Buckle a wire side for spliced sediment trapping net, by wide cut between 30cm to 65cm, the plastic wire of degree of porosity between 10% to 45% and S shape buckle and form, S shape buckles interval 15cm to 50cm and puts on the base of plastic wire.

One buckles spliced sediment trapping net, it is characterized in that: vertically put above bottom sediment trapping net top margin by the wire side buckling spliced sediment trapping net of stent support, the top margin of wire side is fixed on the top of support, buckling of wire side base is fixed with the top margin of bottom sediment trapping net, is spliced to form one and buckles spliced sediment trapping net.

Because the wind that blows from horizontal direction is through the stop of sand dune windward slope, when being pooled to top of sand dune, the just very fierce and wind direction extremely unstable of wind-force, so general sediment trapping net is thrown after being easy to be washed in a pan sky by strong wind from base, the spliced sediment trapping net of the utility model has been spliced into entirety with the sediment trapping net fastening of bottom due to buckling of base, and bottom hangs a bag shape high vertical sediment trapping net is embedded in the sand below top of sand dune dearly, highly stable, the base safety of the sediment trapping net spliced up can be ensured, thisly buckle spliced sediment trapping net and just can steadily stand upright at top of sand dune.

Completely although construct buckle the height that spliced sediment trapping net exposes top of sand dune and only have 30cm to 65cm, because sediment trapping face off the net has sand dune to make liner, its sediment trapping effect is just far away higher than the high vertical sediment trapping net of height at more than 1.5m.The exemplary applications that this is " sand-protecting barrier combine with landforms top, desert sediment trapping fix the sand function law " in sand control engineering.

Detailed description of the invention

Now in conjunction with Figure of description, the utility model is further described: a kind of wire side 2 buckling spliced sediment trapping net 1 of formation described in the utility model, by wide cut between 30cm to 65cm, degree of porosity 10% to 45% plastic wire and buckle 3 compositions, buckle 3 S-shaped, the upper end button buckled is hung and is fixed on the base of plastic wire, dangle in lower end, the spacing between buckling is between 15cm to 50cm; Wire side 2 launches, above the top margin being vertically placed in bottom sediment trapping net 6, on wire side base buckle 3 lower end, clasp is on the top margin of bottom sediment trapping net one by one; Promote the height of the support 4 in bottom sediment trapping net to the wire side 2 top margin 1.5cm to 2cm of distance splicing on the sediment trapping net top margin of bottom, as bottom support disappearance, just substitute with new support, cradle top to be tightened with adjacent cradle top with iron wire 10 and is connected, the top margin of wire side 2 is pressed on the top of support 4, fix by tying up silk 5, wire side 2 just stands upright on above the top margin of bottom sediment trapping net 6 under the support of support, forms one and buckles spliced sediment trapping net.

Conclude the utility model one to buckle spliced sediment trapping net and can be described below: a kind of wire side 2 buckling spliced sediment trapping net by wide cut between 30cm to 65cm, the plastic wire of degree of porosity between 10% to 45% and S shape buckle 3 and form, S shape buckles interval 15cm to 50cm and puts on the base of plastic wire.It is described in the utility model that a kind of to buckle spliced sediment trapping net be that the wire side 2 supported by support 4 is vertically put above bottom sediment trapping net 6 top margin, the top margin of wire side is fixed on the top of support 4, buckling of wire side base 3 is fixed with the top margin clasp of bottom sediment trapping net 6, is spliced to form one and buckles spliced sediment trapping net 1.
