Detailed Urban Rail Transit, Subway, Metro Construction Process Introduction
The construction techniques of rail transit projects in the world are mainly divided into segmented rail changing method, rail row laying method, single sleeper comprehensive laying method and push rail laying method.
The technical points of urban rail transit engineering are mainly to master the differences in construction technology in urban rail transit technology. Different construction technologies use different rails in the construction process, and the laying methods of rails are also different. First of all, the key point of the segmented rail replacement method is that the existing seamless line can be directly used for reconstruction, but it needs to be welded into a unit rail section before it can be carried out.
Secondly, the technical points of the rail laying method are the transportation of the rail row and the connection structure of the track.
In addition, the key point of the single sleeper comprehensive laying method is the connection between the single sleeper comprehensive laying method and other rail units. The push rail laying method is simpler than the single sleeper comprehensive laying method, but it is only the a part.
