REINFORCEMENT BUILDING-IN DEVICE OF CAST-IN-PLACE PILE AND BUILDING-IN METHOD

摘要

PROBLEM TO BE SOLVED: To provide a reinforcement building-in device capable of constructing the cast-in-place pile favorable in workability and of high quality by a simple method and its building-in method. SOLUTION: A building-in device of a flexible reinforcement and a tie hoop to use for a cast-in-place pile is constituted of a building-in frame 1 set on a construction foundation G, a building-in device 2 installed on the building-in frame 1 and a lower part frame 4 to contract a lower end of a group of the flexible reinforcement 3 in diameter. Additionally, a building-in method of the flexible reinforcement 3 and the tie hoop to use for the cast-in-place pile is constituted of a process to precedently build the tie hoop in a drilled hole H drilled down to specified depth and a process to build a group of the flexible reinforcement 3 in an inside space of the tie hoop.
