Flow-diverting and wind-curbing road-protection wall for desert highway
Technical field
The present invention relates to the traffic technique field, particularly a kind of unconcerned highway of desertification that is used for the dust storm arid area divides a fluid stream wind road maintenance wall.
Background technology
Along with China's economic development, more and more higher to the attention degree of environment.Because deterioration of grasslands, a large amount of vegetation by broken ring, cause dusty wind weather, sandstorm weather increasing, dust storm is serious day by day to the harm of highway, directly influences the quality and the life-span of highway.
It is the main sand damage of dust storm local highway that sand buries.Highway sand buries and can be divided into long-pending husky, the long-pending husky and long-pending husky three kinds of citation forms of heap shape of ligule of sheet, and is wherein, outstanding with the long-pending sand of sheet.The characteristics of the long-pending sand of sheet are that long-pending husky scope is big, and often long-pending husky full wafer links to each other, and is continuous hundreds of meters even several kilometers along the road surface, and sand bed thickness is generally 10-20cm, and this sand damage causes difficulty for the maintenance on road surface, because of eliminating the long-pending husky lot of manpower and material resources that needs to spend; As if untimely elimination, long-pending sand thickens day by day, can have a strong impact on traffic, even the blocking-up vehicle pass-through.
Existing highway sand damage safeguard procedures are divided into plant protection and engineering protection two big classes usually, for the serious drought and water shortage area of desertification, rely on the natural rainfall plant to be difficult to growth, so plant protection are difficult to carry out; And existing engineering protection method is roadbed to be reinforced protect mostly, effective removal measure of the area sand that do not satisfy the need.
Summary of the invention
The purpose of this invention is to provide a kind of flow-diverting and wind-curbing road-protection wall for desert highway, the sand of organizing natural wind to remove highway pavement buries, to reduce the maintenance workload of desert highway significantly.
The object of the present invention is achieved like this:
Flow-diverting and wind-curbing road-protection wall for desert highway by verge board, shrouding, go up wind deflector, plate axle, middle wind deflector, down wind deflector, earth anchor, chute, pull bar, staple, stay cord, on go out aerofoil, in go out aerofoil, go out aerofoil, column, control down and constitute apart from rope, king-rod axle, lower beam axle, upper boom axle and locking nut.Column is the seamless steel pipe of external diameter 15cm, wall thickness 5mm, and many root posts are positioned at the side that highway facings the wind, and every root post is apart from roadbed 0.5m, the deeply real soil layer 0.8m in the lower end of column, upper end 2.0m above ground level.Along vertical direction arranged between the highway direction two adjacent upright and dual-side respectively with the fixing verge board of two columns.Verge board is that wall thickness is the sandwich steel plate of rectangle of 4cm.The top edge of verge board is concordant with the top of column, and the lower limb of verge board is apart from ground 0.6m.Along also have between the highway direction two adjacent upright horizontal direction, be between verge board lower limb and the ground and two ends respectively with fixing upper boom axle, king-rod axle and the lower beam axle of two columns.Last wind deflector, middle wind deflector, down wind deflector be three have radian, crowning all up, wall thickness is at the glass epoxy of 10-20mm, the lower limb of last wind deflector, middle wind deflector, following wind deflector respectively has an axle sleeve and is placed in respectively on upper boom axle, king-rod axle, the lower beam axle, and upward the lower limb of wind deflector, middle wind deflector, following wind deflector can rotate around upper boom axle, king-rod axle, lower beam axle respectively.Shrouding is the glass epoxy of an inclination, and the higher one side of shrouding is connected with the windward side of verge board, and one side that shrouding is lower is as a whole with the top edge of last wind deflector.Pull bar is that diameter is that 60mm, wall thickness are the steel pipe of 5mm, and pull bar becomes 70 ° inclination angle with ground.The joint of shrouding and last wind deflector is connected with the upper end of pull bar, the lower end of pull bar and earth anchor welding.The longitudinal direction of pull bar has a chute, and the plate axle that is arranged in wind deflector and following wind deflector top edge middle part is in described chute, and is in active relationship with chute, and the end that each plate shaft extension goes out chute is with locking nut.Earth anchor is made of with the bar portion with screw thread the top of semicircle sphere, and the bar portion diameter of earth anchor is 5-8cm and gos deep into real soil layer 0.5m.On go out aerofoil, in go out aerofoil, down go out aerofoil be three have radian, crowning all down, wall thickness is the glass epoxy of 10-20mm, on go out aerofoil, in go out aerofoil, respectively there is a hole lower end that goes out aerofoil down.Control is apart from restricting through aforementioned three holes.On go out aerofoil, in go out aerofoil, the top edge that goes out aerofoil down respectively has an axle sleeve to be placed in respectively on upper boom axle, king-rod axle, the lower beam axle, and on go out aerofoil, in go out aerofoil, go out aerofoil down and all can rotate around upper boom axle, king-rod axle, lower beam axle respectively.Stay cord and control are the wire rope of diameter 15mm apart from rope, the lower end of stay cord with on go out aerofoil the hole link to each other, the upper end of stay cord is connected with the staple of the leeward side that is fixed in verge board.
Adopt such scheme can receive following remarkable result:
The present invention be not merely the baffle plate by vertical direction keep out the wind, because in naked sand ground is closely shown the 2m height, wind speed with altitude is logarithmic relationship, therefore, the present invention dexterously by a plurality of wind deflectors with go out a plurality of streamlineds air channel that aerofoil is formed, will blow to highway wind along the line do vertical the division, and be compressed into that three strands of upper, middle and lower have that high wind is pressed and different wind speed, paste the cleaning wind band on ground at a high speed.Down, in, last three strands of cleaning wind bands are responsible for highways respectively along horizontal trizonal cleaning works from the near to the remote, thereby realized utilizing highway pavement self-cleaning of natural wind.Like this, save a large amount of highway maintenance work, saved a large amount of highway maintenance expenses, simultaneously, quality that improves highway pavement and the life-span that prolongs highway pavement have been had positive role.
2. the present invention does not need to use concrete fully in installation, building course, and this dry wind sand ground district in lack of water is crucial.
3. the present invention is simple in structure, is beneficial to very much transportation and assembling.
4. wind deflector all can be controlled apart from rope and chute, locking nut by stay cord, control respectively with the position that goes out aerofoil, can carry out flexible modulation according to local wind speed average, has stronger versatility.
