Abstract
A kind of method protected using low vertical sand barrier aeolian sand subgrade, the wide leveling bands of 20m are set respectively in roadbed both sides, the wide bands that fix the sand of at least 500m are set with outside in the leveling of windward side, the wide bands that fix the sand of at least 200m are set with outside in the leveling of leeward side；Fixing the sand, band excavates latticed groove, and sand-protecting barrier materials are embedded in groove, and sand is trained in sand-protecting barrier both sides, then selects suitable season, is adapted to the grass-seed of local growth, is sowed in sand-protecting barrier grid.
Description
Technical field
The present invention relates to Desert Highway to build technical field, and in particular to a kind of desert highway method for preventing and stabilizing sand.
Background technology
Desert area is built highway, and to ensure highway safety, it is an important ring to carry out sand prevention in both sides of highway, fix the sand
Section.At present desert area drift-sand fill region sand prevention, fix the sand it is more punished using shelter belt, but desert area due to
Water resource lacks, and plantation forest difficulty is big, and not only cost is high, and sand prevention, sand-fixing effect are unsatisfactory,.
The content of the invention
It is an object of the invention to for problem existing for current desert highway preventing and fixing sand, use setting low vertical as far as possible
Sand-protecting barrier is protected, and is being ensured sand prevention, on the premise of punishment effect of fixing the sand, is being reduced difficulty of construction, save construction cost.
Technical scheme is as follows：
A kind of method protected using low vertical sand barrier aeolian sand subgrade, it is characterised in that comprise the following steps：
(1) stalk or branch bar are cut into no more than 45cm length, as sand-protecting barrier materials；
(2) the wide leveling bands of 20m are set respectively in roadbed both sides, set at least 500m wide in the leveling band outside of windward side
The band that fixes the sand, the wide bands that fix the sand of at least 200m are set with outside in the leveling of leeward side；
(3) latticed groove is excavated in the band that fixes the sand, grid single lattice size is 1m*1m, ditch groove width 4cm, is deep to few 30cm；
(4) sand-protecting barrier materials are embedded in groove, form sand-protecting barrier；Sand-protecting barrier buried depth 30cm, leakage are no more than 15cm；Sand-protecting barrier materials
Measure as 6000Kg/1000m2；
(5) sand is trained in sand-protecting barrier both sides after sand-protecting barrier is formed, husky use is trained and is manually tamped, keep sand-protecting barrier to hang down during training sand
Directly；
(6) select suitable season, be adapted to the grass-seed of local growth, sowed in sand-protecting barrier grid；Grass-seed dosage is
4.5Kg/1000m2。
The present invention using low vertical sand barrier carry out Highway Subgrade in Desert protection, can directly utilize corn stalk, Sunflower Pole,
Reed, the branch set etc. are reinforced, and cost is cheap, and speed of application is fast, and protection effect is good.Sand-protecting barrier grid is close, sows grass-seed
Afterwards, afforestation effect is obvious.Sapling need not be bought to protect using forest belt, save a large amount of expenses.
In the application example of the present invention, Highway house is the Yellow River alluvial plain, its desert of storehouse cloth through area
Area and maidan area, geomorphic type are broadly divided into three classes, and height above sea level is between 1000~1500m.All fronts roadbed both sides are equal
For drift-sand sand dune landforms, the preventing and fixing sand greening of highway subgrade both sides is carried out using the low vertical sand barrier of the present invention, compared to use
Forest belt construction of prevention work, difficulty of construction is greatly reduced, and taken with construction speed, construction quality etc. from the cost of construction
Obtained good result.
Brief description of the drawings
Fig. 1 is the construction process figure of the present invention；
Fig. 2 is the subgrade protection band cross-sectional view of the present invention；
Fig. 3 is the set-up mode schematic diagram for the low vertical sand barrier that the present invention uses.
Embodiment
The construction process of the present invention is as shown in figure 1, specifically include following steps：
(1) stalk or branch bar are cut into no more than 45cm length, as sand-protecting barrier materials；Stalk includes corn stalk, certain herbaceous plants with big flowers
Flower stalk, reed etc., materials are prepared enough.
(2) as shown in Fig. 2 setting the wide leveling bands 2 of 20m respectively in the both sides of roadbed 1, leveling band is repaired smooth.Meeting
The leveling of wind side sets the wide bands 3 that fix the sand of at least 500m with outside, sets at least 200m wide with outside in the leveling of leeward side
Fix the sand band.The direction of arrow is wind direction in Fig. 2.
(3) latticed groove is excavated in the band that fixes the sand, grid single lattice size is 1m*1m, ditch groove width 4cm, is deep to few 30cm；
Channel excavation construction before, survey crew be able to will be fixed the sand according to drawing tape load point releasing, determined afterwards by site operation personnel's bracing wire
Go out 1m*1m grid.
(4) as shown in figure 3, the sand-protecting barrier such as stalk or branch bar materials are embedded in groove, sand-protecting barrier 4 is formed；Sand-protecting barrier buried depth
30cm, leakage are no more than 15cm；Sand-protecting barrier material quantity is 6000Kg/1000m2。
(5) sand is trained in sand-protecting barrier both sides after sand-protecting barrier is formed, husky use is trained and is manually tamped, sand-protecting barrier should be kept during training sand
Vertically, if any topple in time by sand-protecting barrier righting and will training it is husky steady and sure.
(6) select suitable season, be adapted to the grass-seed of local growth, sowed in sand-protecting barrier grid；Grass-seed dosage is
4.5Kg/1000m2。
Grass-seed selection will be adapted to local climate (temperature and precipitation) and soil condition, well developed root system, have good solid soil and
Protection effect；Coverage is big, density is big, lodging resistance is good；Antiviral, green phase long, perennial, resistance to trample, preferably nature
Breeding is continued and grow；There is stronger desertification property.
