摘 要:In the process of tunnel construction, it is inevitable that there will be various kinds of working face cross-operation, especially the interaction between inverted arch construction and the entire excavation and support working face ahead is particularly prominent. Limited by the requirement of safe step distance, the inverted arch construction greatly affects the overall construction progress of the tunnel. For this reason, a high-efficiency equipment forms a trestle bridge which does not interfere with each other and is convenient and fast, which is the guarantee of tunnel progress and safety. A foreign railway project adopts domestic 24m clear span high-efficiency hydraulic self-propelled inverted arch trestle bridge, which effectively solves the mutual interference between working procedures and forms the effect of three-dimensional operation and rapid construction, thus playing a good practical application value.
