Description

Technical Field

[0001] The utility model relates to the technical field of tunnel engineering, in particular to an escape pipe. Background Art

[0002] Tunnels are generally built on the seabed, on mountains or in other complex terrains. Some of the construction sites are remote, with complex terrain and undulating terrain. The proportion of caves or cracks is as high as 40%, which brings many unsafe factors to tunnel construction. In order to ensure the safety of construction workers, it is generally necessary to set up escape pipes from the heading to the outside of the tunnel, so that the safe section and the heading are connected through the escape pipe, so that when the tunnel collapses or hazards occur, workers can selectively enter the escape pipe to avoid risks and wait for rescue, and rescue personnel can also quickly enter the accident site through the escape passage.

[0003] The escape tunnel is laid as the tunnel face is constructed. In related technologies, the escape tunnel is formed by splicing multiple pipes, and the pipes are laid along the excavation direction of the tunnel, that is, the open end of the pipe faces the tunnel face. Since mud and gravel will fall outward during the construction of the face, it is very easy to fall into the opening of the pipe facing the face and may even block the escape pipe, and it is also easy to damage the part of the escape pipe close to the face. In addition, the connection at the joints of multiple pipes is unstable, and sand and water leakage may even occur. In severe cases, the escape pipe may be blocked. Therefore, it needs to be improved. Utility Model Content
