Document Type and Number:
Japanese Patent JP2016191191
Kind Code:
A
Abstract:
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
