Title:
REINFORCING METHOD OF SINGLE COLUMN FOOTING
Document Type and Number:
Japanese Patent JP3938393
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a reinforcing method of a single column footing used for pile bent pier, etc.
SOLUTION: All of immersion bodies 20 constituted of a plurality of segment pieces are jacked forcedly into the ground around the pile bent pier 10. The insides of the immersion bodies 20 are excavated by underwater excavation, and the circumference of the pile bent pier 10 is excavated downward. Then, cconcretes 24 and 27 are cast into the immersion bodies 20, and a stiffening body 1 making the immersion bodies 20 as the prototype is formed around the pile bent pier 10. Then, since all of the immersion bodies 20 are jacked forcedly into the ground, the stiffening body 1 making the immersion bodies 20 as the prototype is in a state to fix to the pile bent pier 10. By the constitution, and since the stiffening body 1 can be fixed to such a place as flexural rigidity of the pipe bent pier 10 is increased, the pile bent pier 10 can be reinforced against bending load. Furthermore, before the concrete 27 is cast, it is monolithically formed through reinforcing bars 25, etc., arranged inside of the immersion bodies 20, and the stiffening body 1 making the immersion bodies 20 as the prototype is surely fixed to the pile bent pier 10.
