Embodiment 1

[0050] See also image 3 , this embodiment discloses a multifunctional connection device for tunnel escape pipes, the track 101 is a "concave" structure, and a horizontal fixing rod 102 is welded between the tracks 101 to play a role of reinforcement and balance.

Embodiment 2

[0052] See also Figure 4 , this embodiment provides another multifunctional connection device for tunnel escape pipes, which differs from Embodiment 1 in that:

[0053] The track 101 is an "I" type structure, the lower part of the track 101 is buried underground, and the upper part of the track 101 is used to ensure that the mobile connection moves on a set path. When installing, a part of the track 101 Buried underground, partly exposed to the ground.

[0054] Working principle: First, install the track assembly 1 at the designated position; secondly, move several mobile connection assemblies 2 to the track assembly 1 and cooperate with the track assembly 1; finally, place the escape pipe unit sections 4 on the pipe one by one On the connection part 203, and make the two adjacent escape pipe unit sections 4 closely fit;

[0055] When the mobile connection assembly 2 reaches the specified position, turn the rotating piece 2042 downward, or step on the pedal 2044 to make the...

Abstract

The invention relates to the technical field of highway and railway tunnel safety construction, and discloses a multifunctional connection device for a tunnel escape pipeline, whichcomprises a track assembly, the track assembly is provided with a matching mobile connection assembly, the mobile connection assembly is provided with a parking part,the mobile connection assembly comprises moving parts matched with the track assembly, each of the two or more moving parts is detachably connected with a supporting part, and the supporting part is provided with a pipeline connecting part; and the pipeline connecting part is provided with an escape pipeline unit section, a pipeline connection part is of an arc-shaped structure, and the escape pipeline unit section is a circular pipe and exactly arranged in the pipeline connecting part. The device is to solve the problem of the advancing movement of the escape pipe inside the tunnel, and the connection problem between the escape pipeline unit sections is also solved, thus laying and moving of the escape pipeline are easy and quick, and the tunnel construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of road and railway tunnel safety construction, in particular to a multifunctional connection device for a tunnel escape pipeline. Background technique [0002] The construction of highway tunnels in my country started relatively late. Compared with foreign developed countries, the relevant technical level is still relatively low. In addition, the characteristics of highway tunnels, such as large spans, complex construction techniques, and variable terrain, lead to many technical problems in the process of highway tunnel construction. Although the new Austrian construction technology of highway tunnels in our country has become more and more mature, and the relevant design theory and construction technology of tunnels with complex geological conditions have achieved certain results, collapse accidents have occurred frequently during tunnel construction, and construction safety problems are extremely serious. ...
