INNER MOLD AND TUNNEL EXCAVATOR WITH INNER MOLD |
摘要 |
PROBLEM TO BE SOLVED: To provide an inner mold and a tunnel excavator provided with the inner mold for improving construction efficiency of a tunnel by facilitating axial pull out work of a demolding piece. SOLUTION: The inner mold W is used in the tunnel construction method that the inner mold W is assembled into a ring shape along a peripheral wall of the tunnel excavated with the tunnel excavator and that the tunnel is excavated while forming a lining wall by substantially continuously placing concrete in the space between the inner mold W and the peripheral wall of the tunnel at the construction site. The inner mold W is divided into a plurality of pieces K1-K4 and D1-D4 in the circumferential direction. Division surfaces of all the pieces are formed to be oriented toward a substantial center O of the inner mold W, and at least a single piece D1 which can be removed in an axial removing method at the time of form removal is divided into a body Da and an outer plate Db, so that the body Da can be removed leaving the outer plate Db behind at the time of the form removal.
