Abstract

PURPOSE:To shorten a construction period by constructing a main girder column capital section, and at the same time constructing the main tower as a fixed section of a diagonal material in a projecting construction method of the PC cable-stayed bridge. CONSTITUTION:Blocks C1-C5 of a corbel section and blocks T1 and T2 of the main tower are constructed. Then prefabricated scaffoldings 2 are re-shored, a plurality of main tower blocks are constructed on the block T2, at the same time, a lower stage horizontal beam is constructed, and a main girder column capital section is constructed. Then, a plurality of main tower blocks are also constructed on the main tower blocks, and the highest block is used for a fixed section on the main tower side. Wagons W1 and W2 are built up, fixed sections K1 and K2 of first diagonal cables B1 and B2 of a main girder are constructed, and the cables B1 and B2 are tensioned. While repeating the construction of both main tower and main girder at the same time, the diagonal cables are tensioned to construct a diagonal tensiole bridge. Since the main girder column capital section and main tower as the fixed section of the diagonal are not separately constructed as in a conventional construction, a construction period can be shortened.
