Abstract

The invention discloses a flexible air pipe installation device for long and large tunnel construction. The flexible air pipe installation device comprises a movable frame and an installation height indication device installed at the top of the movable frame. The movable frame comprises a supporting frame body and a walking mechanism. The installation height indication device comprises a horizontal top board and a telescopic strut for supporting the horizontal top board. The horizontal top board is provided with an air pipe installation height detection unit which is a height sensor for detecting the height of the horizontal top board in real time. The supporting frame body is provided with an air pipe installation length detection unit which is a detection unit for detecting the walking route length of the supporting frame body in real time. A control box is arranged on the supporting frame body. The telescopic strut is a telescopic hydraulic cylinder. The flexible air pipe installation device is simple in structure, reasonable in design, easy and convenient to use and operate and good in use effect; and in the installation process of a flexible air pipe, the installation height of the air pipe can be indicated, and the installation length and the installation height of the flexible air pipe can be monitored in real time.

Description

technical field [0001] The invention belongs to the technical field of tunnel ventilation construction, and in particular relates to a flexible air duct installation device for long tunnel construction. Background technique [0002] At present, the tunnel construction ventilation at home and abroad mostly adopts the pipeline press-in ventilation method, and an axial flow fan is installed outside the tunnel entrance, and the axial flow fan sends fresh air to the tunnel excavation working face through the ventilation pipe (that is, the flexible air pipe) connected to it. , the dirty air in the cave is expelled out of the cave along the body of the excavated cave under the extrusion of the fresh air sent into the cave. When the tunnel is long, multiple axial flow fans are used in parallel and in series to increase the air volume and air supply distance. But nowadays, most of the above-mentioned fans and ventilation ducts are constructed manually. For long tunnels, the on-site ...
