Transport system and method for small-section extra-long tunnel

Abstract

The invention relates to a transport system for a small-section extra-long tunnel. The transport system comprises traction locomotives, rail-mounted transport carts, an intra-tunnel transport route and an extra-tunnel transport route. The intra-tunnel transport route is a monorail transport route, a plurality of meeting lanes are arranged on a rail of the monorail transport route, and the meeting lanes are single-turnout meeting lanes and are arranged on the same side of the rail of the intra-tunnel transport route. The extra-tunnel transport route comprises a turning area, a slag unloading area, a loading and emergency area, a charging overhaul area and a parking area, wherein the turning area is communicated with the intra-tunnel transport route, and the slag unloading area, the loading and emergency area and the charging overhaul area are communicated with the turning area. The turning area comprises at least two rail lines and is communicated with the part, extending out of a portal, of the rail of the intra-tunnel transport route through a turnout. The slag unloading area comprises a slag unloading platform and at least two slag unloading rail lines, and the slag unloading rail lines are communicated with the turning area through a turnout and a rail. The invention further relates to a transport method for the small-section extra-long tunnel.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering construction, in particular to a small-section extra-long tunnel transportation system and a transportation method. Background technique [0002] In the construction of extra-long tunnels for railways and highways, the safety tunnel parallel to the main tunnel serves as an auxiliary construction channel during the construction of the main tunnel. Clearance dimension of the initial support section of the safety tunnel: the width is about 5m, the height is about 5.5m, and the excavation volume is 28m 3 Left and right, because the clearance width in the initial support of the safety tunnel is relatively small, it cannot meet the requirements of the ballast on the reloading machine and the width of the dump truck in the tunnel. In addition, the excavation size of the single head of the safety tunnel is relatively deep. When it reaches a certain depth, ventilation in the tunnel is difficult ...

Problems solved by technology

Clearance dimension of the initial support section of the safety tunnel: the width is about 5m, the height is about 5.5m, and the excavation volume is 28m 3 Left and right, because the clearance width in the initial support of the safety tunnel is relatively small, it cannot meet the requirements of the ballast on the reloading machine and the width of the dump truck in the tunnel. In addition, the excavation size of the single head of the safety tunnel is relatively deep. When it reaches a certain depth, ventilation in the tunnel is difficult , and in order to meet the requirements of the construction period and progress indicators, the transportation system and transportation method in the safety tunnel construction play a vital role. The muck generated during construction requires a scientific, reasonable, environmentally friendly and smooth transportation system and transportation method to discharge the muck, so as to ensure the safety of the tunnel construction progress and meet the requirements of the construction period
