Abstract (en)
[origin: WO9713039A1] An unsymmetrical steel sheet pile and a method for manufacturing the same in which good joint shapes can be obtained without forming any convex portion by making a joint portion of a sheet pile wall become flush with a flat arm portion, while in forming a joint bend neither unstable rolling posture nor incomplete joint is provided, and a corner steel sheet pile and a method for manufacturing the same, both being used for the unsymmetrical steel sheet pile and a method for manufacturing the same. One of unsymmetrical joints has a turned-up shape, while the other has a turned-down shape, and in forming left and right joint bends rolls with different passes are used on respective sides for finishing the bends. During this process, while the formation of one of the joint bends is being finished, the other joint is only restrained in the pass with bend formation not carried out at all or carried out halfway. The corner steel sheet pile is manufactured by inverting either the inward joint portion of the above unsymmetrical steel sheet pile or the outward joint portion thereof. In another method, it is possible to manufacture it by inwardly bending either of the joints.
