[0004] At present, tunnel construction requires a large number of steel arches and advance small conduits. First, the steel arches are spliced ​​and formed, and then the advance small conduits are inserted through the belly of the steel arches into the front soil and rock layer. Then cement mortar is injected into the advance conduit to adhere to the front soil and rock layer as a whole before the next cycle of excavation can be carried out. The first is to strengthen the initial support of the tunnel, and the second is to carry out safe construction operations. At present, the holes for the ultra-small conduits on the web of the steel arch are cut with oxygen + acetylene or plasma gas. A large amount of smoke will be generated during the cutting process, and the cut apertures are of different sizes, and professional personnel must be required to operate.
