CONTINUOUS WALL CONSTRUCTION METHOD AND EXCAVATING MACHINE

PROBLEM TO BE SOLVED: To provide a continuous wall construction method etc., in which a continuous wall can be easily constructed.SOLUTION: In an excavation part 110a formed by excavating the foundation 100, one steel-made continuous wall member 10a and the other steel-made continuous member 10b are built while connected by inserting a male joint 14 of the other steel-made continuous wall member 10b into the inside of a female joint 13 of the one steel-made continuous wall member 10a, and the periphery thereof is filled with soil mortar 140. Then a guide hole 43 is formed by holing the soil mortar 140 inside the female joint 13 of the steel-made continuous wall member 10a at an end of the foundation 100 on the side of an unexcavated part 120. An excavating machine 50 fitted with a guide material 55 outside is used and moved down while the guide material 55 is inserted into a guide hole 43 so as to excavate the unexcavated part 120. Further, the steel-made continuous wall members 10a, 10b are built in the excavation part 110b where the unexcavated part 120 etc., is excavated while connected, and the periphery thereof is filled with the soil mortar 140.
