TEMPORARY RECEIVING METHOD OF EXISTING STRUCTURE
PROBLEM TO BE SOLVED: To provide a temporary receiving method of an existing structure capable of efficiently temporarily receiving a vertical load of the existing structure directly supported by a footing foundation, even under an environment of being unable to remove a floor slab.SOLUTION: A temporary receiving method comprises a first process of executing construction of a groove-shaped work pit capable of passing through an intermediate position of an adjacent footing foundation and primary excavation for constructing a reinforcement space positioned around a foundation beam, a second process of reinforcing the foundation beam and the footing foundation by using the reinforcement space, a third process of improving the ground under the footing foundation and on its periphery, a fourth process of secondarily excavating the ground under an underground beam by leaving the ground under the footing foundation and a fifth process of driving a temporary receiving pile in at least any one of under the foundation beam and under the footing foundation.SELECTED DRAWING: Figure 4
【課題】床スラブを撤去できない環境下においても、フーチング基礎で直接支持された既設構造物の鉛直荷重を、効率よく仮受けすることの可能な、既設構造物の仮受け工法を提供する。【解決手段】隣り合う前記フーチング基礎の中間位置を通過可能な溝状の作業坑の構築と、基礎梁の周囲に位置する補強空間を構築するための一次掘削とを行う第１の工程と、補強空間を利用して、基礎梁およびフーチング基礎を補強する第２の工程と、フーチング基礎下およびその周囲を地盤改良する第３の工程と、フーチング基礎下の地盤を残して地中梁下の地盤を二次掘削する第４の工程と、基礎梁下と、フーチング基礎下のうち、少なくともいずれか一方に仮受け杭を打設する第５の工程と、を備える。【選択図】図４
