METHOD FOR REINFORCING EXISTING CONCRETE STRUCTURE
To provide a method for reinforcing an existing concrete structure capable of reinforcing a wall that receives a load from the ground behind it, even under the constraint that it is difficult to increase the thickness as reinforcement at a front side of the wall.SOLUTION: A method for reinforcing an existing concrete structure having a wall 3 that receives a load from the ground behind it comprises: a space formation step of cutting a reinforcement target part 5 of the wall 3 to form a space 6 that exposes a reinforcement bar 10; a hole formation step of forming a pair of holes 11 along a main steel bar 7 on a pair of cutting surfaces 8 across the space 6; a reinforcement bar arranging step of arranging the reinforcement bar 10 so as to connect the pair of cutting surfaces 8 while inserting the reinforcement bar 10 into each of the pair of holes 11; and a concrete placing step of placing concrete in the space 6 so as to seal the main steel bar 7 and the reinforcing bar 10.SELECTED DRAWING: Figure 2
【課題】補強として壁部の手前側に増厚することが難しい制約の下においても、背面地盤からの荷重を受ける壁部を補強することが可能となる既設コンクリート構造物の補強方法を提供する。【解決手段】既設コンクリート構造物の補強方法は、背面地盤からの荷重を受ける壁部３を有する既設コンクリート構造物の補強方法であって、壁部３のうちの補強対象部分５を斫って補強筋１０を露出させる空間６を形成する空間形成工程と、空間６を挟む一対の斫り面８に主鉄筋７に沿って一対の孔１１を形成する孔形成工程と、一対の孔１１のそれぞれに補強筋１０を挿入すると共に、一対の斫り面８同士を結ぶように補強筋１０を配置する補強筋配置工程と、主鉄筋７及び補強筋１０を封止するように空間６にコンクリートを打設するコンクリート打設工程と、を備える。【選択図】図２
