The purpose of the present invention is to provide a front tip structure for constructing a tunnel structure by a non-open-cut method, which can freely adjust a movement angle even if a tunnel is constructed on a curved alignment besides a straight alignment, and has simple constituents to adjust the movement angle. To this end, the front tip structure for constructing a tunnel structure by a non-open-cut method comprises: a front end shoe (100) which includes a body (110) formed to have a predetermined width along an edge part of a space where the tunnel is to be formed, and an inclined plate (120) provided at the front of the body (110) so that the body (110) is easily injected underground; a back end shoe (200) which has a front end portion (210) inserted into the body (110) of the front end shoe (100) and a back end portion (220) extended backwards alongside the body (110), and is supported by a support beam (600) not to be pushed backwards; multiple proceeding transfer jacks (300) which have opposite ends supported by the front end shoe (100) and the back end shoe (200) and are arranged to be vertically separated from each other at both sides of the space where the tunnel is to be formed; multiple steering transfer jacks (400) which have a front end supported by the front end shoe (100) and a back end supported by the support beam (600) with a length adjusting part (500) therebetween and are arranged to be vertically separated from the proceeding transfer jacks (300) at both sides of the space where the tunnel is to be formed; and a length adjusting part (500) which is provided to change a length to which the steering transfer jack (400) moves forward. |
