Document Type and Number:
Japanese Patent JP3794682
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To largely shorten a construction period of multistage timbering, to reduce a cost, and to obtain accuracy, a speed, and safety of work for installing the timbering in a sheet pile well foundation construction method.
SOLUTION: This method constructs a foundation lower part of a bridge by the sheet pile well foundation construction method. The construction period is shortened by excavating while replacing water and sediment in a well in an excavating process. A bracket for arranging second stage timbering on the inner peripheral side of a sheet pile is constituted as a collapsible bracket. A flat bar is fixed to a sheet pile inner peripheral side curved surface top surface, and a suspending bracket for arranging third stage timbering is fixed to the lower end. After tentatively assembling the third stage timbering by the collapsible bracket, the timbering is suspended by a suspending tool, the collapsible bracket is folded up, and the third stage timbering is slid downward and immersed, and is placed, assembled, and installed on the suspending bracket. Afterwards, the collapsible bracket is restored to a present state, and the second stage timbering is placed, tentatively assembled, and installed on the bracket.
