<P>PROBLEM TO BE SOLVED: To provide a circular installation method of steel sheet piles capable of accurately installing the steel sheet piles by holding the upper end part of a preceding steel sheet pile in a stable state by a clamp part of a self traveling movement type press-in device when connecting a plurality of the steel sheet piles in a circular arcuate shape of a small curvature radius and pressing and installing them. <P>SOLUTION: In the circular installation method of steel sheet piles 11 using a self traveling movement type press-in device 10, to the distal end side first and distal end side third preceding steel sheet piles 11'a and 11'c, in the state of respectively interposing an adjusting attachment plate 20 having a tapered part 20a of a taper angle α corresponding to a crossing angle θ of the tangential direction s2 of the distal end side second preceding steel sheet pile 11'b and the tangential directions s1 and s3 of the distal end side first or distal end side third preceding steel sheet pile 11'a or 11'c between front and back holding surfaces 21, the upper end parts of the distal end side first and distal end side third preceding steel sheet piles 11'a and 11'c are held by the clamp part 14 of the self traveling movement type press-in device 10, and the next steel sheet pile 11 is pressed in and installed underground. <P>COPYRIGHT: (C)2012,JPO&INPIT |
