Abstract

PURPOSE: To facilitate the correction of the thrust direction of a thrust pipe by fixing a cutter head at the end of the inner pipe of an inner and outer double pipe, and installing a semicircular slant plate for receiving excavated earth pressure in the rear part thereof rotatably. CONSTITUTION: A cutter head 9 including a bit 8 is secured to the tip end of the inner pipe 1 of a thrust pipe 3. Also, a slant heat sleeve 5 is installed in the end of an outer pipe 2 rotatably, and a semicircular slant plate 7 is fastened to the tip end thereof. While, a target 13 having a center lamp 11 and a direction current lamp 12 is inserted airtightly in the end inner part of an inner pipe 1, and a clutch mechanism 14 is provided which engages therewith only during reverse rotation; in addition, an earth intake screw 4 is set on the outside of the inner pipe 1. Thus, when dislocation is yielded in the thrust direction, directional correction can be done easily only by allowing the slant plate 7 at the dislocation yielded side.
