BINDING ENGINEERING METHOD OF CAISON AND FOUNDATION PILE

摘要

PROBLEM TO BE SOLVED: To provide a binding engineering method of a caison and a foundation pile capable of sufficiently securing binding power while speedily depositing binding concrete of the caison and the foundation pile. ;SOLUTION: This binding engineering method is to integrate a caison 1 and a foundation pile by depositing pile head binding concrete C2 underwater in a dead space after sinking the caison 1 through the foundation pile in the dead space formed by burying a sleeve pipe 50 in a bottom base concrete C of the caison 1. Thereby, an irregular part is formed by previously fixing band steels 53, 54 on an inner surface of the sleeve pipe 50 and on an outer surface of the foundation pile, and binding power is secured even without arrangement of reinforcing bars. Consequently, work is speedily progressed without arrangement of the reinforcing bars and attachment of seaweeds to reduce binding power of the pile head binding concrete C2 is prevented.;COPYRIGHT: (C)1998,JPO
