Improved steel pipe piles and pipe pile structures

Abstract

A pipe pile, for use in a foundation or a retaining wall, comprises a substantially cylindrical, and preferably steel, pipe body extending longitudinally between two opposite ends, the pipe body being' formed of a plurality of pipe sections, interlocked or welded together end-to-end and arranged on a common central longitudinal axis between the two ends, All of the pipe sections have substantially the same outside diameter; however, two or more pipe sections have differing inside diameters, and thus a differing wall thickness, between the two ends of the pipe pile.

Description

technical field [0001] The present invention relates to improvements in tubular piles, especially steel tubular piles, adapted to be driven into soil for use as structural elements in foundations or in walls. More specifically, the present invention relates to a metal pipe pile for use in foundations or walls which is corroded by the natural environment. Background technique [0002] Steel undergoes a natural corrosion process when it is in contact with water and at the same time present in air with oxygen. Material wear by corrosion depends on the one hand on local (eg hydrological) conditions and on the other hand the vertical position of the steel relative to the water level. When tubular piles are driven into the seabed, for example to support above-water or offshore platforms or to form seaside retaining walls, different vertical areas of the tubular piles experience different rates of corrosion or "rust".
