SUPPORT COLUMN REINFORCEMENT CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a support column reinforcement construction method capable of smoothly arranging a reinforcing frame in a predetermined location on the ground even if any obstruction exists in a subsided location.SOLUTION: A bridge pier reinforcement construction method in which a reinforcement steel plate frame is arranged spaced from and surrounding the periphery of a bridge pier, the lower part of the reinforcement steel plate frame is pushed into the ground via a cutting edge provided on the lower end part of a first reinforcement frame, and a corner part of a cavity between the reinforcement steel plate frame pushed into the ground and the peripheral surface of the bridge pier is filled with a filler so as to reinforce the bridge pier, the method implementing a boring step (step s1) for boring a plurality of places along the peripheral surface of the bridge pier in the depth direction, a reinforcement steel plate frame installation step (step s3) for pushing the lower part of the reinforcement steel plate frame into the ground, and a filler filling step (step s4) for filling the corner part of the cavity with the filler, in this order.SELECTED DRAWING: Figure 5
【課題】沈下箇所に障害物がある場合であっても補強枠を地盤内の所定箇所にスムーズに配置できる支柱補強工法の提供を目的とする。【解決手段】橋脚の周囲に対して間隔を隔てて取り囲むように補強鋼板枠を配置するとともに、第１補強枠の下端部に設けられた刃口を介して補強鋼板枠の下部を地盤内に圧入し、地盤内に圧入した補強鋼板枠と橋脚の周面との間の空隙の角部に充填材を充填して橋脚を補強する橋脚補強工法において、橋脚の周面に沿う複数箇所を深さ方向に削孔する削孔工程（ステップｓ１）と、補強鋼板枠の下部を地盤内に圧入する補強鋼板枠設置工程（ステップｓ３）と、空隙の角部に充填材を充填する充填材充填工程（ステップｓ４）とをこの順で行った。【選択図】図５
