[0002] During the construction of underground caverns, smoke and dust are inevitably generated. However, underground caverns are relatively closed, and it is difficult to maintain stable construction when smoke and dust escape into the underground caverns. Most of the existing air supply and smoke exhaust methods install blowers at the excavation opening of the underground caverns to exhaust the smoke and dust.

[0003] In the existing tunnel construction, the length of the tunnel continues to increase during the construction process, and may be several thousand meters in the later stage. Therefore, when supplying air and exhausting smoke, it is necessary to continuously lengthen new air ducts according to the tunnel construction process to ensure the air supply and smoke exhaust effect. Most of the existing air ducts are connected by flanges, and the installation and docking process of the air ducts is extremely troublesome, time-consuming and labor-intensive, which will affect the tunnel construction process.
