STRUCTURE OF IMMERSED TUNNEL

摘要

PROBLEM TO BE SOLVED: To provide a structure of an immersed tunnel 1 capable of withstand ing a large stress applied to the immersed tunnel 1. SOLUTION: In this structure of the immersed tunnel 1 constituted by connecting case bodies 2, flexible mechanisms 3 arranged on a cross section crossing substantially orthogonally in the axial direction of the immersed tunnel 1 are arranged in at least two sections or more at an interval shorter than a length in the axial direction of one case body 2. Moreover, in this structure of the immersed tunnel 1 constituted by connecting the case bodies 2, the flexible mechanisms 3 arranged on a cross section crossing substantially orthogonally in the axial direction of the immersed tunnel 1 are arranged in at least two sections or more in the same case body 2. In this structure of the immersed tunnel 1, a correction device 4 for adjusting displacement in the direction crossing the direction of tunnel axis substantially orthogonally is arranged in the vicinity of front and rear parts in the direction of tunnel axis of the flexible mechanism 3.
