PROBLEM TO BE SOLVED: To provide a construction method for a sidewall and a connection structure of the sidewall and a segment for facilitating its construction work, preventing corrosion of a connection means, and providing excellent durability. SOLUTION: First of all, the ground is excavated to form a tunnel 1, and the segment 3b is provided on an internal wall of the tunnel 1. The segment 3b has recessed and projecting parts 13 on its inner face. Next, a pedestal 17 is installed in the tunnel 1, and a member 15a for forming the sidewall by units is provided on the segment 3b by using a crane 25 on the pedestal 17. Then, a form 35a is provided around the member 15a for forming the sidewall by units, and concrete is placed to construct the sidewall 5a. At this time, the pedestal 17 is used as an arch center. Since the sidewall 5a and the segment 3b resist fulcrum reaction force of a floor slab by shear capacity of the recessed and projecting parts 13 and bearing of the concrete of the sidewall, a process for mounting a dowel separately becomes unnecessary and the construction work is facilitated.
