[0002] Tunnels are engineering structures buried in the ground, and are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels.

[0003] During the tunnel construction process, construction workers enter the interior of the tunnel. However, due to the great depth of the tunnel, the air in the tunnel is blocked, causing the carbon dioxide content in the air in the tunnel to increase.

[0004] Therefore, during the tunnel construction process, it is necessary to install a dust removal and oxygenator inside the tunnel to extract the air in the tunnel and pump the external air into the tunnel, so as to realize the exchange of the air in the tunnel with the external air and maintain the oxygen content of the air in the tunnel;

[0005] However, dust removal and oxygenation require the use of different pipes, but multiple pipes will take up space in the tunnel, reducing the construction space of the tunnel. Utility Model Content
