  • U-shaped sheet pile with low cut-through resistance
    Patent number: 6190093
    Abstract: A U-shaped sheet pile comprising a flat flange (10), two flat webs (12) connected to the flange (10) so as to be symmetrical with respect to a plane (8) perpendicular to the flange (10), and an interlocking element located at the end of each of the two webs (12). The sheet pile has a depth/useful width ratio greater than or equal to 0.18. The concave corners (18) defined by the two flange/web connections are significantly flattened by an extra thickness (26) of material so as to obtain a reduction in the resistance of the sheet pile to pile-driving. The extra thickness (26) is sufficient for a fictitious cylindrical surface (38), which has a radius at least equal to 75 mm and which is tangential to the planes extending the inner faces of the flange and the web (32, 34), to be completely located inside the said extra thickness (26) between its two tangential generators.
