LANDSLIDE PREVENTION PILE AND CONSTRUCTION METHOD FOR THE PREVENTION PILE

摘要

PROBLEM TO BE SOLVED: To provide a prevention pile also serving as a drainage well for preventing landslide and further reduce the construction work cost and the term of works. ;SOLUTION: A steel cylinder 15 constructed under the ground comprises ring bodies 13 split in the axial direction (vertical direction) and many split rings 1 split in the circumferential direction. This construction is performed by pressing accompanied by drilling the inside of the steel cylinder 15. A cutting edge is provided on the lower edge of the lowermost split ring 1 to decrease peripheral surface frictional resistance due to presing. A cylindrical reinforcement bar cage 35 is built in the inside of the constructed steel cylinder 15, and the reinforcement bar cage 35 is connected to the inner surface of the steel cylinder 15. An innder formwork 39 is arranged in the reinforcement bar cage 35, and concrete is placed between the steel cylinder 15 and the inner formwork.;COPYRIGHT: (C)1998,JPO
