  • Patent number: 8167515
    Abstract: The hot-rolled straight-web steel sheet pile comprises a straight web delimited on each longitudinal side respectively by an interlock strip. The web has a rolled-in taper which is designed in such a way that, in a tensile test of two samples from this sheet pile which are connected by means of their interlock strips, the web is deformed plastically in the region of this taper before a failure of the interlock connection can occur. The rolling of such a sheet pile, which is distinguished in cellular cofferdams by a high plastic deformation capacity, can take place by means of slightly modified standard rolls and consequently requires no major investment.
