Zibo tunnel apparatus and method are disclosed. Girder device for supporting a tunnel formed in the ground inside the tunnel according to an embodiment of the present invention, the cylindrical bolt is provided with a first diameter; And a cylindrical hole of the first diameter such that the bolt is mounted is formed on the inside, provided with a compressible elastic material in the spacing member comprises a cylindrical support portion having a first thickness of a second diameter, the support, the bolt and the at least one first hole, the air in the perforation that the bolt when the bolt is inserted to inject the grout material is filled into the perforations which are inserted into the grout injection pipe for injecting a grout material filled in the perforated mounting is inserted and further comprising at least one second hole is equipped with a discharge pipe for discharging the air. Girder tunnel method according to an embodiment of the present invention is by using a spacing member having a resilient compressible material, which is installed at a predetermined interval in the body of the bolt for jibojae tunnel, and a uniform filling of the juipjae inserted between the bolt and the possible perforation, is to prevent the disconnection of the attachment of the ground and of the bolt according to the breakage of juipjae (grouting material) by receiving the kidney due to the bolt axial force acting on the advantage of keeping the tunnel Girder ability.
