Cavity bridge tower with rapid ventilation function
By designing ventilation hoods and turbine ventilation sheets on the cavity bridge tower, the suction force generated by air circulation is used to accelerate air circulation, and the temperature stress problem caused by the temperature difference of the bridge tower is solved, and rapid ventilation and temperature difference balance is achieved without affecting the appearance and structural strength of the bridge tower.

AI Technical Summary
Under the action of temperature load, the existing cavity bridge tower has a large temperature difference between the outside and the inside, resulting in large temperature stress. The existing ventilation hole design is not smooth, and the temperature difference cannot be quickly balanced, which affects the appearance and structural strength of the bridge tower.
A cavity bridge tower with fast ventilation function is designed, and the ventilation cap is used to fix it with the bridge tower body through a steel base and communicate with the top ventilation hole. The turbine ventilation plate and rotary support mechanism are used to accelerate the air circulation and achieve rapid balance of internal and external temperature differences.
By quickly and effectively reducing the temperature difference between the inside and outside of the bridge tower, the effect of rapidly reducing the temperature stress of the bridge tower without affecting the appearance and structural strength of the bridge tower.
