[0002] Tunnel ventilation is a safeguard measure to provide fresh air to workers and maintain the normal operation of electromechanical equipment. Most tunnels use duct pressure to supply air to the heading face. A fan is installed outside the tunnel entrance. The fan sends fresh air into the tunnel through the duct connected to it. The duct is usually hung on the tunnel arch wall. During the installation of the duct, the duct may be damaged and leaked due to improper operation of the personnel. Damaged and leaked ducts will reduce ventilation efficiency, especially in plateau areas with low pressure and low oxygen content. Damaged and leaked ducts may cause personnel safety problems. Therefore, it is necessary to inspect the quality of the duct.

After the test is completed, it is necessary to manually use the equipment to move the pipelines away. Loading and unloading materials is troublesome, time-consuming and labor-intensive, resulting in slow efficiency in air duct quality testing.
