Description

Technical Field

[0001] The utility model relates to the field of tunnel ventilation, in particular to a tunnel structure. Background Art

[0002] Tunnel engineering is a building built underground or underwater or in a mountain to lay railways or build roads for motor vehicles to pass. According to its location, it can be divided into three categories: mountain tunnel engineering, underwater tunnel engineering and urban tunnel engineering. Mountain tunnel engineering is to pass under mountains or hills to shorten the distance and avoid steep slopes; underwater tunnel engineering is to pass under rivers or straits or under the sea; urban tunnel engineering is to pass underground in cities to meet the needs of railways passing through large cities. Among these three types of tunnel engineering, mountain tunnel engineering is the most built.

[0003] refer to Fig. 9 , Fig. 9 This is a schematic diagram of the installation of existing tunnel ventilation ducts. Tunnels need to be installed with air ducts for ventilation during construction. The existing ventilation ducts are all canvas hoses. For ease of installation, the fan is installed in a flat position. The fan draws outside air into the tunnel through the ventilation duct. The part of the ventilation duct exposed to the outside of the tunnel is easily exposed to the sun and the temperature of the transported air increases. At the same time, there is a turn when the air duct is connected to the fan and leads to the tunnel. Due to the hot weather shining on the surface of the air duct, the wind transported into the tunnel becomes hot and dry. In addition, the folding of the hose causes air volume loss during the turning process, which makes it less practical.

[0004] Therefore, it is necessary to provide a tunnel structure to solve the above technical problems. Utility Model Content
