Abstract

PURPOSE:To make it possible to construct a tunnel having a larger section at a low cost with small diameter shield machines by inserting gradually preliminary small diameter tunnel structures provided to the outside thereof in advance to widen a diameter after formation spaces of a series of the small diameter tunnel structures of which a tunnel structure is constituted are gradually widened at specific positions. CONSTITUTION:Preliminary small diameter tunnel structures 4' are so constructed that they are respectively inserted among small diameter tunnel structures 4, 4,... in every other way. At that time, those small diameter tunnel structures 4' are constituted of shield tunnels. Among the extra small tunnel structures, they are overlapped with the preliminary common small diameter tunnel structures 4' to gradually widen only a space between adjacent small diameter tunnel structures 4 and 4 each other. According to the constitution, the preliminary small diameter tunnel structures 4' are gradually inserted between the small diameter tunnel structures 4 and 4 to be separated. Accordingly, in a tunnel having a larger section, the section can be rationally widened.
