    • This low-cost, light-weight, high-strength, hollow cylindrical pile having longitudinal ribs is manufactured by rolling an elongated metal plate of predetermined width so as to produce spaced ridges thereon extending at a predetermined angle between lateral edges. The ridged metal plate is spirally wound so that the ridges register to produce longitudinally-extending ribs and the juxtaposed lateral edges are joined, preferably by welding, to form a continuous spiraled joint. When driven into a penetrable medium, the ribs provide directional control and means for joining adjacent piles into a unitary structure.
    • 这种具有纵向肋的低成本,重量轻,高强度的中空圆柱形桩通过滚动预定宽度的细长金属板来制造,以便产生间隔开的脊部,其在横向边缘之间以预定角度延伸。 脊状金属板被螺旋卷绕,使得脊部对准以产生纵向延伸的肋,并且并置的侧边缘优选地通过焊接接合,以形成连续的螺旋接头。 当被驱动到可穿透介质中时,肋提供方向控制和用于将相邻桩连接成整体结构的装置。

    • The invention relates to a sheet pile section for erecting partly or continuously double-walled sheet piles comprising a web and two flanges welded to said web and projecting on either side of said web, each flange-end being designed as one half of a connecting lock for interlocking with an adjacent section, wherein the improvement resides in that the flanges are provided with the same wall thickness over their total extension and with hook-shaped ends which are formed by cold roll bending and bent back towards the web. This section, the web width of which may be freely chosen, is capable of absorbing great axial forces and bending moments. Also, it is capable of exercising high resistance moments with respect to its weight.
    • 本发明涉及一种用于竖立部分或连续的双层板桩的片材桩部分,其包括幅材和焊接到所述幅材的两个凸缘并且在所述幅材的任一侧上突出,每个凸缘端被设计为连接锁的一半 用于与相邻部分互锁,其中的改进在于凸缘在其总延伸部上设置有相同的壁厚,并且具有通过冷辊弯曲形成并且朝向腹板弯曲的钩形端部。 可以自由选择腹板宽度的这一部分能够吸收大的轴向力和弯矩。 此外,它能够相对于其重量行使高电阻力矩。
