NATM Bogie conveyor sediment handling device in NATM method tunnel

摘要

The present invention relates to a bogie conveyor soil treatment apparatus in a NATM tunnel, which carries soil generated during tunnel excavation to the rear by a conveyor, the conveyor consisting of a front conveyor 10 and a rear conveyor 30. , The front and rear conveyors 10 and 30 are installed inside the front and rear bogies 100 and 300, respectively, and the front bogie 100 retreats when the tunnel is excavated, and when the soil is loaded with a bucket, the front bogie 100 is By moving forward, the front belt conveyor, the middle belt conveyor, and the rear belt conveyor are located inside the front, middle, and rear trucks, respectively, and the front, middle, and rear trucks overlap each other or spread forward and backward. The city moves forward and carries the soil into the bucket, so continuous work is possible quickly without interruption of work. There is no noise or dust caused by the movement of the excavated soil, and there is no traffic of large vehicles in the tunnel. smoke. There is no noise, and there is a remarkable effect of ensuring the safety and health of workers.
