摘 要：
PROBLEM TO BE SOLVED: To provide a method for correcting a leading ring joint surface when the leading ring joint surface is not flush with a flat surface orthogonal to the direction of progress of excavation.;SOLUTION: The assembling method for the inner form comprises the step of installing a plurality of form pieces 40 of the inner form along an inner peripheral surface 33 of a tunnel cavity section 21 formed by excavating a natural ground 20 to form a lining section
between itself and the inner peripheral surface of the tunnel cavity section to cover the whole inner circumference along the inner peripheral surface of the tunnel cavity section 21 to form a ring-shaped inner form 30 and successively assembling the ring-shaped inner forms in the advancing direction of excavation. A correction ring joint surface 52 is formed for making correction by using a
correcting component (stroke adjusting liner 50) with a predetermined thickness so that the leading joint surface 47b can be flush with the flat surface orthogonal to
