Bus body air duct

The main functions of the rail top air duct are: (1) Ventilation and heat dissipation at the top of the train. The train air-conditioning condenser is set on the top of the train compartment. When the air conditioner is running, the heat inside the compartment is dissipated to the air on the top of the compartment through the air-conditioning condenser. The diffusion of hot air in the tunnel increases the temperature of the tunnel. The station rail top air duct can efficiently discharge the heat emitted by the subway air conditioning system to the outside world, so as to achieve the standard of not exceeding 40 degrees in the maximum temperature in the tunnel in summer. (2) As the fixed base surface of the catenary. (3) As the upper load-bearing and sealing component of screen doors or safety doors.

The main construction procedures of the post-cast-in-situ rail top air duct are: erection of steel pipe supports → excavation of pre-embedded steel bars → overall steel bar fabrication → installation of air duct bottom plate formwork → inspection of reserved holes → acceptance → pouring of concrete for the bottom plate and the lower half of the hanging wall →Install the hanging wall formwork→Acceptance →Pouring the hanging beam concrete.
