Abstract
The invention aims to provide an overlapped-splicing type sand-blocking net and a construction method of the overlapped-splicing type sand-blocking net and belongs to the technical field of desertification control projects. The technical problem to be solved and the technical task provided by the invention are to overcome the defects of an existing sand-blocking net and to allow the sand-blocking net to be manufactured into the overlapped-splicing type sand-blocking net with a hanging buckle on a bottom edge. The construction method of the overlapped-splicing type sand-blocking net comprises the following steps of fixing the top edge of the overlapped-splicing type sand-blocking net onto the top of a bracket which is vertically lifted from the inner part of a bottom-layer sand-blocking net, and fixing the lower end of the hanging buckle on the bottom edge of the sand-blocking net with the top edge of the bottom-layer sand-blocking net so as to form the overlapped-splicing type sand-blocking net which is erected on the top of the bottom-layer sand-blocking net.
Description
Technical field
The present invention relates to sand control engineering technical field, be specially a kind of lap splice formula sediment trapping net and construction method thereof.
Background technology
At present, in desert treatment, be widely used plastic wire construction high vertical sediment trapping net, implement the interception in flow desert and fix, but above-mentioned high vertical sediment trapping net due to vertical wire side suffer strong wind when invasion and attack not only wire side easily blown brokenly, the wind being stopped changes over upper and lower vertical direction from horizontal direction, the sand that wind vertically downward can erosion sediment trapping sieve bottom, make sediment trapping sieve bottom unsettled, therefore construct just very unstable at the top at moving dunes and check dam.
Applicant is by the experimental construction of for many years mechanical sand barrier sediment trapping being fixed the sand, from observe the mobile rule in desert and the desert dynamic law occurring landforms top, desert arranges sand-protecting barrier, draw " sand-protecting barrier 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 the fixing desert of flowing, 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 husky amount of resistance 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 desert landforms (moving dunes, sand bar, Sha Geng) top isohypse.
According to " sand-protecting barrier combine with landforms top, desert sediment trapping fix the sand function law ", moving dunes are can be by sand-protecting barrier being set at top of sand dune, make moving dunes by passing forward, change over upwards and raise, and become the check dam with intercepting desert function.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 and do not reach completely successfully target, until in 2013, " the outstanding bag shape high vertical sediment trapping net " of applicant's design just successfully fixed the dune ridge line at moving dunes tops completely, in the middle of " the outstanding bag shape high vertical sediment trapping net " arranging, do not rupture, long moving dune chain is upwards piled highly from passing to change over forward, and harmful moving dunes have been changed over to useful check dam.This just proves " sand-protecting barrier combine with landforms top, desert sediment trapping fix the sand function law " meets objective law.When after the outstanding bag shape high vertical sediment trapping net of gradually having piled high dune ridge line heap buried, the sediment trapping net of just need again constructing on dune ridge line, at this moment, will by heap buried outstanding bag shape high vertical sediment trapping net to raise up recycling not only very difficult, also can destroy dune ridge line, therefore find a kind of utilization by heap buried outstanding bag shape high vertical sediment trapping net the method for new sediment trapping net is set, be the needs of control of desert.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is the vacancy of filling up prior art, a kind of lap splice formula sediment trapping net, construction to by drift sand heap buried the top of sediment trapping net, the sediment trapping net having made by heap buried recovers sediment trapping function again.
Lap splice formula sediment trapping net of the present invention, it is characterized in that: lap splice formula sediment trapping net is that wide cut is between 30cm to 65cm, the plastic wire of degree of porosity between 45% to 10% constitutes with putting many buckling on plastic wire base, buckle S-shaped, upper end is fixed on the base of plastic wire, lower end hangs, and the spacing between buckling is between 15cm to 50cm.
The construction method of lap splice formula sediment trapping net of the present invention, it is characterized in that: be originally placed in top of sand dune by drift sand heap buried the top margin of bottom sediment trapping net clean out Shamian Island, make the windward side of bottom sediment trapping net expose 5cm to 10cm, again the husky landfill of bottom sediment trapping net originally exposing more than top of sand dune 5cm to 10cm is become to the husky ridge, make sediment trapping net only expose husky ridge 5cm to 10cm, then by lap splice formula sediment trapping net unfolding, vertically be placed in the over top of bottom sediment trapping net, and hanging over the lower end that buckles on sediment trapping net bottom limit, prick one by one in the net of top margin below, sediment trapping net windward side, bottom 5cm to 10cm, with pliers buckling lower end and bottom sediment trapping net is fixed, make lap splice formula sediment trapping net and bottom sediment trapping net connect into entirety, then promote the support in bottom sediment trapping net, support is promoted to the height apart from lap splice formula sediment trapping net top margin 1.5cm to 2cm, as bottom support disappearance, just substitute with new support, a top of the trellis is tightened connection with iron wire and an adjacent top of the trellis, the top margin of lap splice formula sediment trapping net 1.5cm to 2cm is pressed in cantilever tip, with tying up silk, lap splice formula sediment trapping net top is tied up and is fixed on a top of the trellis, again the bottom sediment trapping net top margin Desert Sand landfill higher than Shamian Island 5cm to 10cm, form the husky ridge, form the lap splice formula sediment trapping net standing upright on bottom sediment trapping net top.
Due to the wind blowing from horizontal direction stopping through sand dune windward slope, while being pooled to top of sand dune, wind-force is just very fierce and wind direction is extremely unstable, so general sediment trapping net is easy to be thrown from sky is washed in a pan on base by strong wind, lap splice formula sediment trapping net is because buckling with the sediment trapping net of bottom of base connected into entirety, and the outstanding bag of bottom shape high vertical sediment trapping net is embedded in the sand below top of sand dune dearly, highly stable, can ensure the base safety of spliced sediment trapping net, lap splice formula sediment trapping net just can steadily be stood upright at top of sand dune.
Although exposing the height of top of sand dune, the lap splice formula sediment trapping net of constructing complete only has 25cm to 50cm, because sediment trapping face off the net has sand dune to make liner, and the just high vertical sediment trapping net more than 1.5m higher than height far away of its sediment trapping effect.The exemplary applications that this is also " sand-protecting barrier combine with landforms top, desert sediment trapping fix the sand function law " in sand control engineering.From then on " with husky sand control " will enter engineering application from design experiment.
