摘要： PROBLEM TO BE SOLVED: To provide a prestressed concrete well enabling a reduction in construction period and a method of constructing a bridge.
SOLUTION: The prestressed concrete well comprises: a cylindrical prestressed concrete well body 21 and a fixing part 10 which projects from the prestressed concrete well body 21 inward and to which a pier 3 can be attached. The method of constructing the bridge comprises: a foundation construction step S1 of constructing cylindrical prestressed concrete well foundations 2 each having the fixing part 10 on the inner peripheral surface by using the prestressed concrete wells; a temporary fixing step S2 of temporarily fixing the pier 3 to each of the prestressed concrete well foundations 2 by attaching the piers 3 to fixing part 10, an installation step S3 of installing bridge upper part structures 4 between the piers 3; and a fixing step S4 of fixing each pier 3 to each prestressed concrete well foundation 2 by depositing a concrete 80 in each prestressed concrete well foundation 2. The installation step S3 is performed before or simultaneously with the fixing step S4.
