Problems solved by technology
This method solves the problem of installing the smoke and air duct in the tunnel, but because the tunnel is curved, the middle part of the smoke and air duct is easily stuck by the tunnel wall in the depth of the tunnel because there is no guidance when the smoke and air duct is dragged in after assembly , the protruding pipe is in a dilemma, which increases the difficulty of installation

The invention provides an improved dedicated track for pipe installation in a tunnel, which can support and guide a flue, thereby ensuring the smooth installation of the flue. The improved dedicated track comprises a base plate which is installed on a passageway. The invention is characterized in that an angle plate is installed on the base plate in an upside down mode.
Description
(1) Technical field [0001] The invention relates to the technical field of pipeline installation in tunnels, in particular to an improved special track for pipeline installation in tunnels. (2) Background technology [0002] The narrow space of the tunnel determines that it is difficult to install the smoke and air duct inside. People can only crawl forward inside, and it is impossible to install it inside. A method has been designed in the industry to split the flue gas pipe into pipe joints, extend the pipe joints into the pipe, leave the interface of the pipe joints outside the hole, and connect the dragged-in first pipe joint with the second joint. The pipe joints are connected outside the culvert, and then the dragged-in first and second pipe joints are dragged into the culvert, and so on, one section is installed and the other is dragged, and this method is used until the pipeline is installed. This method solves the problem of installing the smoke and air duct in the...
