EARTH RETAINING CONSTRUCTION METHOD AND REINFORCING STRUCTURE OF SHEET PILE USED FOR THIS CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a wholly novel earth retaining construction method capable of largely restraining deflection of the top end of a self-sustaining sheet pipe without using a strut and an anchor, and allowing deep excavation by improving yield strength as the whole earth retaining structure by a skeleton structure for functioning as a scaffold, and the sheet pile unitedly supported by this structure, and a structure having the scaffold function used for this construction method.;SOLUTION: A sheet pile reinforcing structure ST formed of a column member 6 and beam members 7a and 7b is unitedly arranged on the sheet pile 3 in front of the steel sheet pile 3 driven for retaining earth along an excavating area 1', and the deflection of the top end of the sheet pile 3 is restrained by transmitting earth pressure acting on the sheet pile 3 to the foundation ground via the reinforcing structure ST. The reinforcing structure ST can be used as a scaffold.;COPYRIGHT: (C)2003,JPO
