PILE FOUNDATION STRUCTURE, AND REINFORCEMENT METHOD FOR EXISTING PILE
PROBLEM TO BE SOLVED: To provide a new CPR method that reduces a thickness of a reinforcement body while taking advantage of the CPR method that solves a problem with a conventional additional pile method, thereby solving a problem with a conventional technology.SOLUTION: A pile foundation structure of the present invention includes a pile and a reinforcement body. The reinforcement body comprises two layers namely a main reinforcement body and a cushioning reinforcement body, the cushioning reinforcement body having rigidity lower than the rigidity of the main reinforcement body. A reinforcement method for an existing pile of the present invention includes a cushioning reinforcement body formation step and a main reinforcement body formation step. In the cushioning reinforcement body formation step, the cushioning reinforcement body is formed by improving a ground around the existing pile. In the main reinforcement body formation step, the main reinforcement body is formed by improving the ground around the pile directly above the cushioning reinforcement body. The cushioning reinforcement body is formed to have the rigidity lower than the rigidity of the main reinforcement body.SELECTED DRAWING: Figure 1
【課題】本願発明の課題は、従来技術が抱える問題を解決することであり、すなわち、従来の増し杭工法が持つ問題点を解消するＣＰＲ工法の利点を生かしつつ、補強体の厚さを軽減することができる新たなＣＰＲ工法を提供することである。【解決手段】本願発明の杭基礎構造は、杭と補強体を備えた構造である。この補強体は、「本補強体」と「緩衝補強体」の２層で構成され、緩衝補強体の剛性は本補強体の剛性よりも低い。また本願発明の既設杭の補強方法は、緩衝補強体形成工程と本補強体形成工程を備えた方法である。緩衝補強体形成工程では既設杭の杭周辺地盤を改良することで緩衝補強体が形成され、本補強体形成工程では緩衝補強体の直上の杭周辺地盤を改良することで本補強体が形成される。緩衝補強体は、本補強体の剛性よりも低い剛性となるよう形成される。【選択図】図１
