Ventilation apparatus of network tunnel and underground road including underground intersection and junction

摘要

The present invention provides a ventilation system that is divided into a total of two systems by constructing an economical and safe tunnel, one system of ducts for supplying fresh air into the tunnel, and one system of concentrated exhaust pipes capable of discharging the pollutants accumulated in the tunnels. Specific means of the present invention, one of the air supply duct is installed in the longitudinal direction to supply fresh air over the whole section in the main tunnel, the air supply duct is formed at regular intervals at the bottom; A plurality of air supply passages installed in the air supply ducts at predetermined intervals and connected to the outside of the main tunnel; An air supply fan installed in the plurality of air supply passages to supply fresh air; A plurality of concentrated exhaust ducts installed in the air supply ducts at predetermined intervals such that the contaminated air inlets at the bottom pass through the air supply ducts and communicate with the inside of the main tunnel, and the air outlets at the top communicate with the outside of the main tunnel; And exhaust fans installed in the plurality of concentrated exhaust ducts to forcibly exhaust the polluted air.
