Self-adaptive wind barrier system

Abstract

The invention discloses a self-adaptive wind barrier system structurally comprising a first wind barrier device and a second wind barrier device. The second wind barrier device comprises a first windbarrier row, connecting piles, a bridge floor and a second wind barrier row; the connecting piles are arranged between side surfaces of the deck; and the first wind barrier row and the second wind barrier row are respectively arranged at upper and lower ends of the connecting piles. The difference between the numbers of blades in the first horizontal wind barrier row and the second horizontal windbarrier row of the first wind barrier device and the second wind barrier device which are adjacent is one. By rotating the crescent moon structure, whether the semi-crescent moon plate faces the wind direction directly or not is adjusted and thus the local wind speed is changed, so that the wind speed difference between every two adjacent wind barrier rows is increased or decreased, the two adjacent wind barrier rows are inconsistent in speed, and the problems are solved.

Description

technical field [0001] The invention relates to the field of road equipment, in particular to an adaptive wind barrier system. Background technique [0002] For the development and construction of highways, intercity railways, urban expressways, and bridges, when they are built in strong wind areas, the bridge pavement under the action of cross winds will have similar wind speeds above and below the bridge deck, forming common frequency vibrations, which will cause the bridge deck to shake , there are potential safety hazards, so an adaptive wind barrier system is needed to adjust and change the wind speed above and below the bridge deck to improve the safety factor of the bridge. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention is realized through the following technical solutions: an adaptive wind barrier system, the structure of which includes a first wind barrier and a second wind barrier, and the second wind barrier...
