PROBLEM TO BE SOLVED: To provide a launching method making it possible to deliver a bridge body in a low position even if a parapet of a bridge abutment exists at a launch destination.SOLUTION: A launching method which moves bridge bodies 2, 2, 2including a launching machine 1 attached thereto in a bridge axial direction, the method comprising the steps of: reattaching (S2) the launching machine 1 to a high position of the bridge body 2after the bridge body 2reaches a final span L while avoiding interference of the launching machine 1 with a parapet 4a of a bridge abutment 4 at the launch destination; and installing (S4) the bridge bodies 2, 2, 2to the bridge abutment 4 and bridge piers 5, 5in the launch destination by lowering them after the bridge bodies 2, 2, 2reach the bridge abutment 4 in the launch destination.SELECTED DRAWING: Figure 1
【課題】送り出し先に橋台のパラペットがあっても、橋体を低い位置で送り出すことができる送り出し工法を提供する。【解決手段】手延機１を取り付けた橋体２１，２２，２３を橋軸方向に移動させる送り出し工法において、橋体２１が最終径間Ｌに到達した後、手延機１が送り出し先の橋台４のパラペット４ａに干渉しないように手延機１を橋体２１の高い位置に取り付け直す工程（Ｓ２）と、橋体２１，２２，２３が送り出し先の橋台４に到達した後、橋体２１，２２，２３を降下させて送り出し先の橋台４及び橋脚５１，５２に設置する工程（Ｓ４）と、を備える。【選択図】図１
