The Tunnel Sturucture for None Open Cut Type Tunnel Pressing

摘要

More particularly, the present invention relates to an end structure for non-fastening tunnel excavation having a chain excavator mounted on a distal end structure, easy entry into the ground, and excellent workability, A tunnel structure for non-detachable tunnel excavation that forms a tunnel structure in a non-adhered manner, the tunnel structure comprising: a structure body having a predetermined length formed according to a tunnel shape; A front press-in portion constituted by a chain gear installed in front of each of the hydraulic motors, and a chain portion installed in the chain gear and rotated according to rotation of the hydraulic motor, a plurality of hydraulic motors provided inside the structure body; A length adjusting support for connecting the plurality of hydraulic motors to each other and adjusting a gap between the hydraulic motors; And an inner body formed inside the front press-in portion and the length control supporting portion. The present invention is advantageous in that the tunnel structure of the tunnel structure can be reduced due to tunneling of the tunnel structure.
