Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, in particular to an assembled tunnel escape pipe support. Background Art

[0002] The tunnel escape pipe is a personnel escape passage set up by the construction party for the safety of the project. Due to the closed environment of the tunnel construction project, there are many hidden projects, and the hidden dangers of project quality and safety are easy to occur and difficult to control. The geological survey of tunnel projects in some areas and projects is not detailed, and the design depth is insufficient. These factors make the construction of the project unsafe. According to the requirements of the "Nine Regulations on Tunnel Construction Safety" on escape pipes, escape passages must be set up as required during tunnel construction, and it is strictly forbidden to operate without safety facilities in place. The escape pipe bracket refers to a structural member used to fix the pipe support on the ground, but the main frame of the existing tunnel escape pipe bracket is formed by welding, with a length of 9m, which is relatively bulky. As the tunnel excavation depth gradually increases, the problem of inconvenient transportation is gradually exposed. For this reason, we propose an assembled tunnel escape pipe bracket.
