EQUIPMENT FOR ENLARGING TRAIN TUNNEL FOR CONNECTING BORING MACHINE AND OPERATION VEHICLE CONSIDERING OPERATION OF TRAIN, AND METHOD FOR THE SAME

摘要

The present invention relates to an equipment and method for enlarging a train tunnel to connect a boring machine and an operation vehicle in view of operation of a train. When a train is not operated, an operation vehicle is moved to a work position of an existing train tunnel to be enlarged, and then the operation vehicle is connected to a boring machine. The ground in rear of the existing train tunnel is bored by the boring machine having a micro tunnel boring machine (MTBM). Old linings of the existing train tunnel are cut and removed by an existing lining cutting machine mounted on the operation vehicle. New lining segments are assembled within a work range by a new lining assembling machine mounted on the operation vehicle. An anchor for assemble the new lining segments is installed by a drilling machine mounted on the operation vehicle. Backfill grouting is performed between the boring surface of the existing train tunnel and the new lining segments by a grouting machine.
