Background technology
At present in desert treatment; Fix the sand back plantation psammophytes with construction straw checkerboard barrier and plastic wire grid, ecological recovery is produced effect very much, but to fixing very dry unbroken moving dunes that should not plant growing; Said method not only construction cost is high, also can and lose efficacy by the drift sand covering very soon.Scattered seeds by airplane for afforestation seed on the moving sand dune of extremely arid sand is difficult to germinate; More difficult one-tenth is lived; Therefore invent a kind of low preparation cost, easy construction, can fix moving dunes fast; Weedtree boom net splayed net cage sand barrier that does not pollute the environment again and sediment trapping constructing structure thereof have been the needs of desert treatment.
Summary of the invention
The utility model aims to provide a kind of weedtree boom net splayed net cage sand barrier and sediment trapping constructing structure thereof; Weedtree boom net splayed net cage sand barrier; Construction just can be fixed moving dunes on the dune ridge line of moving dunes, purpose is to become useful check dam to harmful moving dunes.The utility model is to be 201120219428.7 to application number, and the utility model name is called dividing an application of " fixing the sand boom net with what weedtree, bamboo, reed were made ".
The described weedtree boom net of the utility model comprises the boom net that fixes the sand with regular shrub branches such as the salix monogolica making of cutting down of needs on the desert.
The utility model splayed net cage sand barrier selects for use wide cut between 25cm to 45cm; Degree of porosity intersects the weedtree boom net that mixes between 30% to 60% makes; Cut out the net sheet that is cut into 10 meters length to the weedtree boom net, netting length is unrestricted, can cut out according to the construction needs and cut.Two overlapping back four limits alignment of sheet of throwing the net; Get the top margin of a long limit as splayed net cage sand barrier; With nylon wire two throw the net sheet top margin link up, make two throw the net sheet top margin both fixed, can open ° angle, 60 ° of angles to 70 to net sheet base again and constitute splayed net cage sand barrier.When dispatching from the factory close up finished product splayed net cage sand barrier base, be rolled into cylindric packing.
When on moving dunes, constructing, move 60cm to 150cm to the sand at dune ridge line top to the windward slope direction, smoothly go out the above dune ridge platform of a wide 60cm; On the dune ridge platform, dig 20cm at interval, the Liang Tiaogou of dark 15cm to 20cm opens tension with weedtree boom net splayed net cage sand barrier; The base separately down; Place Liang Tiaogou to two bases respectively, fill and lead up Liang Tiaogou to the sand that digs again then, be embedded in the Lower Half of splayed net cage sand barrier in the sand; First half heap to the cylinder mould sand-protecting barrier buries desert sand simultaneously, makes the cylinder mould sand-protecting barrier expose its top less than 15cm.On the dune ridge line, be stitched together splayed net cage sand barrier one by one by said structure, the jointing positions of two cylinder mould sand-protecting barriers is tied up fixing with iron wire, and these moving dunes have just been fixed by splayed net cage sand barrier.When the desert drift sand flows to top of sand dune under the blowing of wind and since splayed net cage sand barrier stop that a part of drift sand is blocked in cylinder mould sand-protecting barrier windward slope one side; Part drift sand climbs over splayed net cage sand barrier and falls on the leeward slope on sand dune, and a part of drift sand is piled up at the leeward slope top of cylinder mould sand-protecting barrier after climbing over the cylinder mould sand-protecting barrier, is buried by sand drift up to cylinder mould sand-protecting barrier top and cannot see; At this moment; The cylinder mould sand-protecting barrier just become the sand dune internal fixation the splayed kernel because the resistance of kernel, drift sand still continues at the top of sand dune heap high; Bury up to sand drift and to be higher than more than the cylinder mould sand-protecting barrier top 30cm; Perhaps pass 150cm before the dune ridge alignment, just move 100cm to 150cm to the sand at dune ridge line top to the windward slope direction again, press said structure construction splayed net cage sand barrier again.So repeat construction, splayed net cage sand barrier just changes over upwards heap height to the moving dunes that move forward.Splayed net cage sand barrier is the height that utilizes moving dunes, tackles the desert of flowing, and moving dunes are high more; The sediment trapping effect of splayed net cage sand barrier is good more, and this phenomenon is not introduced on textbook, and the personage among the people of indivedual sand controls has noticed that moving dunes can be transformed into check dam; And there is related article to deliver on the internet; But because the product of its sediment trapping involves great expense, can't on the desert, do the engineering demonstration with its product economically, also can't promote.And splayed net cage sand barrier is cheap, easy construction, and changing over check dam to moving dunes becomes cheap engineering.Applicant's sample project has been demonstrated in the Inner Mongol, Ningxia, Gansu, Qinghai; The applicant has delivered " the fixing and utilizations of moving dunes " in 2009; In article, illustrated the sediment trapping principle and the sediment trapping effect of splayed net cage sand barrier, and the sediment trapping effect formula V=4.5H on the textbook
2Sina (formula 1) is modified as V=4.5 [H+ (H
1+ H
2)/2]
2Sina (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, and V is the husky amount of resistance in (formula 2), H is the height of mechanical sand barrier, H
1Be sand dune windward slope height, H
2Be sand dune leeward slope height, a is the angle of cut.Because splayed net cage sand barrier exposes top of sand dune less than 15cm, if apply mechanically (formula 1) on the textbook, the husky amount of the resistance of splayed net cage sand barrier, available slightly do not disregard explain, in other words, this splayed net cage sand barrier sediment trapping is useless.But in fact expose the splayed net cage sand barrier of top of sand dune less than 15cm; Because being arranged, the sand dune under the cylinder mould sand-protecting barrier makes liner; Its sediment trapping effect is higher than far away and places the moving dunes waist, and height is greater than the high vertical sediment trapping net of 150cm, therefore; (formula 1) is inapplicable to the sediment trapping effect of the splayed net cage sand barrier that is arranged at the moving dunes top, must just can say something with (formula 2).
The applicant sends the Chinese Academy of Sciences paper of " the fixing and utilizations of moving dunes " in December, 2009; Under the vice-president's who is responsible for desert treatment bothering about; Desert analytical test portion of Institute of Analysis of Lanzhou Branch of the Chinese Academy of Sciences, Chinese Academy of Sciences desert and desertification key lab; In May, 2010 " splayed net cage sand barrier lifting check dam " project of applicant has freely been done the wind tunnel experiment detection, it is successful that experiment and detection proof splayed net cage sand barrier promote check dam, construction and experiment indoor construction on the desert; The principle of constructing check dam is identical, and effect is identical; Can directly observe the dynamic process that splayed net cage sand barrier is constructed check dam at wind tunnel laboratory.
