CONSTRUCTION METHOD FOR BRIDGE REINFORCEMENT STRUCTURE
To provide a construction method for a bridge reinforcement which can be easily installed with excellent workability, and also can reinforce a deteriorated existing bridge in a simple manner.SOLUTION: A construction method for a bridge reinforcement structure is provided. Synthetic resin foam blocks 4, 4A and a lightweight banking material 5 having fluidity are used as a filler. First, when the synthetic resin foam block 4, 4A are stacked below a floor slab 3 to fill, and on at least one lateral side of the bridge 1, the synthetic resin foam block 4A with a wall surface material is stacked so that its wall surface material 10 becomes a side wall surface bridge reinforcement structure, and also so that the upper end of the wall surface material 10 of the synthetic resin foam block 4A with a wall surface material, which is stacked on the uppermost stage, is placed at substantially the same height as the undersurface on the lateral side of the floor slab 3. Then, a space between the synthetic resin foam blocks 4, 4A and the floor slab 3 is filled with the lightweight banking material 5 having fluidity and solidified.SELECTED DRAWING: Figure 4
【課題】施工が容易で作業性に優れると共に、既設された老朽化した橋梁を簡易に補強することができる、橋梁補強構造体の施工方法を提供する。【解決手段】充填材として合成樹脂発泡体ブロック４、４Ａと流動性を有する軽量盛土材５とを用い、先ず、床版３の下方に前記合成樹脂発泡体ブロック４、４Ａを積み重ねて充填する際に、橋梁１の少なくとも一方の側方側には、壁面材付き合成樹脂発泡体ブロック４Ａをその壁面材１０が橋梁補強構造体の側壁面となるように、かつ最上段に積み重ねられる壁面材付き合成樹脂発泡体ブロック４Ａの壁面材１０の上端が床版３の側方側の下面と略同一の高さに位置するまで積み重ね、続いて、前記積み重ねられた合成樹脂発泡体ブロック４、４Ａと床版３との間の空間に前記流動性を有する軽量盛土材５を充填して固化させる橋梁補強構造体の施工方法とした。【選択図】図４
