Embodiment Construction
[0028] According to attached figure 1 , in this embodiment, a combined construction structure of urban tunnels, rail transit sections and comprehensive pipe corridors is composed of urban tunnels, rail transit section tunnels and comprehensive pipe corridors.
[0029] Considering that urban underground roads need to form traffic conversion with surface roads and underground garages in surrounding plots, in order to meet the design requirements of urban roads and facilitate connection, urban tunnels are located on the ground floor. The urban tunnel is in the form of a rectangular double-chamber section, with up and down lines, and is separated by a middle partition wall 3. The cross-sectional size is determined by the lane scale, width, height limit, disaster prevention and evacuation, maintenance, decoration, electromechanical installation, etc.
[0030] The urban tunnel of the present invention, the rail transit section and the rail transit section in the combined constructio...
