REINFORCING STRUCTURE FOR EXISTING PILE FOUNDATION
PROBLEM TO BE SOLVED: To enable reinforcing work in a part of a ground surrounded by an existing pile foundation.SOLUTION: Reinforcing work for a part of a ground surrounded by an existing pile foundation 2 may be performed by the following steps for: excavating a ground directly below and around a structure 1 reinforced by an existing pile foundation; connecting an intermediate part 4A of an existing pile 4 that requires reinforcement with intermediate parts 5A, 6A, 7A of three existing piles 5 to 7, in a surrounding area, respectively, using newly installed four connecting beams 41, 42, 43, 44; and filling back the excavated ground. Rigidity of the existing pile foundation 2 improves even when seismic force 51 is input into the existing pile foundation 2. The excavated depth of the ground and a depth of the intermediate parts 4A to 6A from a ground surface may be determined taking into consideration ease of the reinforcing work.SELECTED DRAWING: Figure 1
【課題】地盤の既設杭基礎で囲まれた部分での補強工事を可能にする。【解決手段】既設杭基礎補強構造物１の直下および、その周囲の地盤を掘削し、補強を必要とする１本の既設杭４の中間部４Ａと、それの周囲に存在する３本の既設杭５乃至７のそれぞれの中間部５Ａ，６Ａ，７Ａとを新たに施工する４本の連結梁４１，４２，４３，４４で連結した後に埋め戻すことにより、地盤の既設杭基礎２で囲まれた部分での補強工事を行うことでき、地震力５１が既設杭基礎２に入力された場合でも、既設杭基礎２の剛性が高くなる。上記地盤を掘削する深さ並びに中間部４Ａ乃至６Ａは、補強工事のやりやすさに基づき地表からの深さが決定されればよい。【選択図】図１
