TEMPORARY PIER CONSTRUCTION METHOD
To provide a temporary pier construction method which can perform construction with a wider pile pitch than before, reduce the number of support piles required for constructing the temporary pier, and improve construction costs and period.SOLUTION: A part of an overhanging main girder 30A is protruded across in the extension direction of the temporary pier from the support position of a support pile 20 to form an overhanging portion 38, and an extension overhanging main girder 30B, which is supported by the end part of the protruding portion 38 of the overhanging main girder 30A and a support pile 20b, is hung across, a slab 40 is laid on the extension overhanging main girder 30B to form a superstructure protruding in the extension direction of the temporary pier, and in a state where the joint position between the overhanging main girders 30A, 30B and the support position of the overhanging main girder 30A by the support pile 20a are shifted in the bridge axis direction, the end part of the existing overhanging main girder 30A and the end of the extension overhanging main girder 30B are joined together to provide continuity.SELECTED DRAWING: Figure 2
【課題】従来と比べて杭ピッチを拡げて施工できて、仮桟橋の施工に要する支持杭の本数を削減できて工費および工期を改善できる、仮桟橋の構築方法を提供すること。【解決手段】支持杭２０の支持位置に対して張出主桁３０Ａの一部を仮桟橋の延長方向に向けて張り出して張出部３８を形成し、張出主桁３０Ａの張出部３８の端部と、支持杭２０ｂとに支持させて延長用の張出主桁３０Ｂを掛け渡し、延長用の張出主桁３０Ｂ上に床板４０を敷設して仮桟橋の延長方向に上部工を張り出して形成し、張出主桁３０Ａ，３０Ｂ同士の接合位置と支持杭２０ａによる張出主桁３０Ａの支持位置とを橋軸方向にずらした状態で、既設の張出主桁３０Ａの端部と延長用の張出主桁３０Ｂの端部との間を一体に接合して連続性を持たせた。【選択図】図２
