Document Type and Number:
Japanese Patent JP2021123961
Kind Code:
A
Abstract:
To provide a rational construction method of a pile head part reinforcement structure of a foundation pile installed into the ground.SOLUTION: A method for connecting a foundation pile 2 installed into the ground and a foundation structure (for example, foundation slab 4) constructed above a pile head part of the foundation pile 2, and constructing a pile head part reinforcement structure 3 for reinforcing the pile head part of the foundation pile 2 includes: an excavation recess formation step (S2) of excavating ground G so as to expose the pile head part of the foundation pile 2, and thereby forming an excavation recess 20 in the ground G; a first mold installation step (S4) of installing a first cylindrical mold 10 on a bottom surface 20a of the excavation recess 20 so as to surround the periphery of the pile head part of the exposed foundation pile 2; and a concrete installation step (S8) of installing concrete 15 into the first mold 10. The first mold 10 is made of precast concrete. The pile head part reinforcement structure 3 includes the first mold 10, and the concrete 15 installed into the first mold 10.SELECTED DRAWING: Figure 3
