Description
Technical field
The present invention relates to sand control engineering technical field, be specially the construction method that moving dunes fixed by outstanding bag shape high vertical 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 the invasion and attack suffering strong wind not only wire side easily blown brokenly, the wind 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, construct just very unstable at the top of moving dunes and check dam, therefore invent the construction method that a kind of outstanding bag shape high vertical sediment trapping net fixes moving dunes and fix the needs that moving dunes have been control of desert.
Applicant has delivered " the fixing and utilizations of moving dunes " in 2009.In article, set forth the principle on splayed net cage sand barrier fixed flow sand dune, illustrate simultaneously after moving dunes top arranges splayed net cage sand barrier, due to husky toward eminence properties of flow, tall and big moving dunes just become tall and big machinery and hinder less.Therefore the mechanical sand barrier on textbook is hindered husky effect formula V=4.5H
2sima (formula 1), is modified as V=4.5 [H+ [(H1+H2)/2]
2sima (formula 2), in (formula 1), V is the husky amount of resistance, and H is the height of mechanical sand barrier, and a is the angle of cut.In (formula 2), V is the husky amount of resistance, and H is the height of mechanical sand barrier, and H1 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 for 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 smooth desert, being highly greater than the high vertical sediment trapping net of 150cm.Therefore (formula 1) husky effect of resistance of arranging Eight characters cylinder mould sand barrier in moving dunes top to constructing is inapplicable, just can must describe the problem with (formula 2).After moving dunes top arranges splayed net cage sand barrier, top of sand dune is deposited in by the drift sand that splayed net cage sand barrier is tackled, 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, the mechanical sand barrier of height like this, cannot accomplish with the high vertical sediment trapping net that any method builds, thus show moving dunes efficient intercepting desert function, but the mechanical sand barrier be so efficiently easy to get on desert, also be not familiar with by people at present, so far fail to find correlation theory and experimental data in textbook.What textbook was introduced is waist high vertical sediment trapping net being arranged on moving dunes, and reach the object of scabbling moving dunes, people still process moving dunes as disaster so far.So applicant is managing by engineering practice, proving that moving dunes to be transformed into tall and big mechanical sand barrier.
