Description

Technical Field

[0002] A tunnel is an engineering structure buried in the ground. It is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels.

[0003] The construction progress of long and large tunnels often depends on whether the ventilation technology can create conditions for long-distance single-headed rapid excavation. At present, the ventilation of newly built railway tunnels in China generally has the problem of insufficient effective air supply to the working face. The construction of long and large railway tunnels mostly speeds up the construction progress by increasing trackless transport inclined shafts, but trackless transport inclined shafts are seriously polluted, especially for a single inclined shaft that undertakes the construction of more than two working faces. The ventilation of the working face will be very difficult. Due to the long length of single-headed excavation, the requirements for the diameter of the air duct and the fan are very high, and the ventilation efficiency is difficult to guarantee. During the construction process, the work efficiency is often reduced due to ventilation difficulties, the progress is slow, and the safety is difficult to guarantee. At the construction site, for the safety of the site, the air supply outside the tunnel is often kept on until there is no personnel in the tunnel for construction. Although this ensures the safety of the gas in the construction environment inside the tunnel, it consumes a lot of electricity and causes an extreme waste of resources. Therefore, it is necessary to provide a new long tunnel segmented pressurized air supply device to solve the above technical problems. Utility Model Content
