Abstract
The invention relates to a crosswind guiding device used for pre-shielding crosswind before and after a vehicle meets a wind shielding obstacle. The crosswind guiding device at least comprises a first wind guiding unit and a second wind guiding unit, which are arranged on the two sides of the wind shielding obstacle; the first wind guiding unit and the second wind guiding unit are shaped like slopes; and from the wind shielding obstacle, the slope of the first wind guiding unit and the slope of the second wind guiding unit gradually approach a road surface where the vehicle runs on downwards in a road surface extending direction far away from the wind shielding obstacle. According to the crosswind guiding device provided by the invention, as it is only required to additionally arrange a wind barrier near the wind shielding obstacle (such as a tower column) for shielding the crosswind, a safety problem that the vehicle is slewed and rolled over due to sudden disappearance of the crosswind is solved; and the cost is low and the mounting time is short. The slope dimensions of the crosswind guiding device as well as the appearance, dimension and arrangement of baffles can be adjusted according to factors such as specific meteorological conditions, the width of the tower column and the like so that an air uniformizing and flow-stabilizing effect is achieved.
Description
Technical field
The present invention relates to a kind of pre-abat-vent, particularly a kind of beam wind air ducting.
Background technology
Along with continuing to increase of bridge span, the charming appearance and behaviour effect of bridge is more and more outstanding.The king-post position of such as bridge, the beam wind faced due to Longspan Bridge is very large, and the area of beam wind faced by king-post is also relatively large, so king-post will shelter from the beam wind of a part.When vehicle drives to the Bridge position corresponding to king-post, the safety problems such as vehicle will break away because of suddenly disappearing of beam wind, inclination, affect the safety traffic of vehicle.
Adding air partition is the Main Means reducing bridge floor wind speed, increase bridge floor road-ability, improve bridge using function.As Hangzhou China gulf bridge, Hong Kong Tsingma Bridge, French rice about viaduct etc. all added air partition.But these air partitions need to add to be located on bed rearrangement bridge, to ensure the safety of driving a vehicle.A part of cost that this mode is very large beyond doubt to the construction of Great span bridge, and need to expend the very long set-up time.
Summary of the invention
The technical problem to be solved in the present invention is: add air partition take time and effort to overcome existing Longspan Bridge, and the deficiency that cost is higher, the invention provides a kind of beam wind air ducting.
The technical solution adopted for the present invention to solve the technical problems is: a kind of beam wind air ducting, keep out the wind in advance running into the beam wind before and after the obstruction that keeps out the wind for vehicle, beam wind air ducting of the present invention at least comprises the first wind deflector unit and the second wind deflector unit that are arranged on obstruction both sides of keeping out the wind, the profile of described first wind deflector unit and the second wind deflector unit is ramped shaped, and the slope of the slope of the first wind deflector unit and the second wind deflector unit is from the obstruction that keeps out the wind, along road surface bearing of trend to the direction away from the obstruction that keeps out the wind, gradually downwards near the road surface that vehicle travels.
Described first wind deflector unit and the second wind deflector unit are by some baffle plate compositions be intervally arranged, at least there is a windward side in described baffle plate, the angle α > 0 ° on the road surface that described windward side and vehicle travel, the angle β < 90 ° of windward side and road surface bearing of trend.
Angle α is 60 ° ~ 100 °, and angle β is 30 ° ~ 60 °.
The shape of described baffle plate is arc or bending shape, and the high H of bow of baffle plate is 5m ~ 1m.
Adjacent screen be arranged in parallel, and the space D between adjacent screen is 0.5m ~ 2.5m.Like this, between baffle plate and baffle plate, beam wind passage can also be formed, make beam wind just passing beam wind passage in beam wind passage after multiple impact baffle plate, reducing the beam wind wind-force after passing baffle plate.
The slope height L on the slope of the first wind deflector unit and the slope of the second wind deflector unit is 5m, slope angle θ is 15 ° ~ 60 °.
Described first wind deflector unit and the second wind deflector unit are arranged axisymmetricly relative to the obstruction that keeps out the wind.
Described first wind deflector unit and the second wind deflector unit near the side of the obstruction that keeps out the wind all with keep out the wind bar contact or partly overlap.
The described obstruction that keeps out the wind is the king-post on bridge, and described road surface is the road surface on bridge.
Also comprise mounting bracket, described mounting bracket is provided with slot, and each baffle plate is plugged in described slot.
The invention has the beneficial effects as follows, beam wind air ducting of the present invention, only need add air partition blocking near the obstruction that keeps out the wind (such as king-post) of beam wind, avoid the safety problem that vehicle breaks away because beam wind suddenly disappears, rolls, cost is lower and the set-up time is short; The slope of beam wind air ducting is from the obstruction that keeps out the wind, along road surface bearing of trend to the direction away from the obstruction that keeps out the wind, gradually downwards near the road surface that vehicle travels, thus from the obstruction that keeps out the wind, reduce the size of the baffle plate blocking beam wind gradually, beam wind is increased gradually to both sides with baffle plate from the obstruction that keeps out the wind, avoids beam wind suddenly disappear at obstruction place of keeping out the wind and affect normal vehicle operation; The slope size of beam wind air ducting and the geomery of baffle plate and arranging situation can adjust according to factors such as the width of concrete meteorological condition and king-post, realize the effect of even wind current stabilization.
