CONSTRUCTION METHOD FOR CORRUGATED STEEL WEB BRIDGE USING GIRDER WAGON

摘要

PROBLEM TO BE SOLVED: To provide a construction method for a corrugated steel web bridge for lightening the weight of a wagon, facilitating construction and reducing cost.;SOLUTION: The invention is composed of a plurality of corrugated steel web 40a and a lower floor slab 50a at the tip end of an existing completed bridge while a box girder 41a of a corrugated steel web plate wherein an upper floor slab is not executed is protrusively provided. A girder wagon 21, whose one end is supported by the existing part of the corrugated steel web bridge, is projected in the bridge extending direction. Being suspended and supported by a travelable suspension means provided on the girder wagon 21, a new corrugated steel web 40b is moved to a construction position at the end of the bridge and is connected to the tip end of the existing corrugated steel web 40a. Then, a lower floor slab 50b is placed on the corrugated steel web 40b, so as to form the corrugated steel web girder box 41b and at the same time to construct an upper floor slab 60 on the existing corrugated steel web girder box 41a.;COPYRIGHT: (C)2008,JPO&INPIT
