Abstract
The invention aims to provide a suspended bag-shaped high vertical sand stopping net and belongs to the technical field of desertification engineering. The suspended bag-shaped high vertical sand stopping net aims to realize that on the basis of an existing high vertical sand stopping net with a single suspended cloth such as a curtain, the existing high vertical sand stopping net can be modified into a design that desert sand can be loaded in the suspended bag-shaped high vertical sand stopping net, in this design, the suspended bag-shaped high vertical sand stopping net is provided with a front side and a rear side and a support therebetween, sand is filled on the lower portion of the net, and the sand stopping net is prevented from washing out and blowing down from the bottom by the gale. The suspended bag-shaped high vertical sand stopping net is constructed on the top of a moving dune and debris dam, which functions in fixing the moving dune and the debris dam.
Description
Technical field
The present invention relates to sand control engineering technical field, be specially outstanding bag shape high vertical sediment trapping net.
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 when the invasion and attack that suffer strong wind not only wire side easily blown brokenly, the wind being stopped changes over upper and lower vertical direction from horizontal direction, the sand of wind meeting erosion sediment trapping sieve bottom vertically downward, make sediment trapping sieve bottom unsettled, construction is just very unstable at the top at moving dunes and check dam, therefore invent that a kind of outstanding bag shape high vertical sediment trapping net fixes moving dunes and check dam has been the needs of control of desert.
Applicant has delivered " the fixing and utilizations of moving dunes " in 2009, in article, illustrate the principle on splayed net cage sand barrier fixed flow sand dune, illustrate at moving dunes top simultaneously and arranged after splayed net cage sand barrier, due to the husky characteristic flowing toward eminence, tall and big moving dunes have just become tall and big mechanical sand barrier, therefore the mechanical sand barrier on textbook are hindered to husky effect formula V=4.5H
2sin a (formula I), is modified as V=4.5H
2+ [H1+H2]
2sin a (formula 2); In (formula 1), V is the husky amount of resistance, the height that H is mechanical sand barrier, and a is the angle of cut.In (formula 2), V is the husky amount of resistance, and the height .H1 that H is mechanical sand barrier is the height of moving dunes windward slope, and H2 is the height of moving dunes leeward slope, and a is the angle of cut.The top of exposing moving dunes due to splayed net cage sand barrier is less than 15cm, if apply mechanically the formula on textbook, be placed in the splayed net cage sand barrier at moving dunes top, it is very little hindering husky effect, but in fact expose the splayed net cage sand barrier that top of sand dune is less than 15cm, owing to there being the moving dunes under cylinder mould sand barrier to make liner, it hinders husky effect far away higher than being arranged on high vertical sediment trapping net on smooth desert, that be highly greater than 150cm.Therefore (formula 1) is inapplicable in the husky effect of resistance of the splayed net cage sand barrier at moving dunes top to constructing, and must just can describe the problem with (formula 2).Arrange after splayed net cage sand barrier at moving dunes top, tackled by splayed net cage sand barrier the drift sand getting off and be deposited in top of sand dune, by promoting splayed net cage sand barrier, make the upwards lifting of moving dunes top, moving dunes just no longer move forward, harmful moving dunes just become useful mechanical sand barrier, and so mechanical sand barrier of height is cannot accomplish with the high vertical sediment trapping net that any method builds.Thereby show the function in the efficient intercepting of moving dunes desert.But the mechanical sand barrier being so efficiently easy to get on desert, is not also familiar with by people at present, fails so far to find correlation theory and experimental data in textbook.What on textbook, introduce is the waist that high vertical sediment trapping net is arranged on to moving dunes, reaches the object of scabbling moving dunes, and people still process moving dunes as disaster so far.So applicant is managing by engineering practice, prove that moving dunes are to be transformed into tall and big mechanical sand barrier.
Outstanding bag shape high vertical sediment trapping net is applicant from the fixing moving dunes of construction splayed net cage sand barrier and constructs the engineering practice of check dam and explore out, outstanding bag shape high vertical sediment trapping net is constructed at moving dunes top and check dam top, more stable than splayed net cage sand barrier, highly can exceed splayed net cage sand barrier, therefore sediment trapping, sand-fixing effect are better than splayed net cage sand barrier, because the bottom of outstanding bag shape high vertical sediment trapping net is to have filled the husky bag end, weather-proof effective, can not blown down from the base erosion of net by strong wind.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is the defect that overcomes prior art, the constructing structure of existing high vertical sediment trapping net, hang as curtain from single width, change over the outstanding bag shape high vertical sediment trapping net that the mesh bag shape that Desert Sand hangs up was housed like the bag end, make sediment trapping netting gear have front wire side and rear wire side, can drift sand interception in desert hanged between bag two wire sides of shape high vertical sediment trapping net and the both sides, front and back of sediment trapping net.
Sediment trapping net of the present invention be wide cut between 120cm to 350cm, the plastic wire of degree of porosity between 45% to 55%.
The outstanding bag of the present invention shape high vertical sediment trapping net, it is characterized in that: the cross sectional shape of outstanding bag shape high vertical sediment trapping net is the sediment trapping net that the outstanding bag shape that Desert Sand hangs up is housed at the bottom of mesh bag bag, the center of the position of sediment trapping net support in outstanding bag shape sediment trapping net, the bottom of sediment trapping net support is fixed in desert through hanging bag bottom vertical of shape sediment trapping net, interval 1M to 2M is equipped with a support, and connection is tightened by an iron wire in the top between support one by one; Prop up a top margin for top of the trellis and outstanding bag shape sediment trapping net and fix, the top margin interval 30cm to 50cm of sediment trapping net and iron wire connect to be fixed; The height of outstanding bag shape high vertical sediment trapping net is freely selected between 25cm to 150cm.
Outstanding bag shape high vertical sediment trapping net has changed the structure of traditional high vertical sediment trapping net, make sediment trapping netting gear have the wire side of two inclinations, can drift sand interception in desert be fixed in the middle of two wire sides that hang bag shape high vertical sediment trapping net and the both sides, front and back of net, due to the bottom of sediment trapping net be filled husky mesh bag at the bottom of, strong wind can not produce erosion to the base of sediment trapping net, be applicable to very much the top of construction at moving dunes and check dam, do not increasing under the prerequisite of cost, reaching the object that improves fixing moving dunes and construct check dam sediment trapping effect.
