Extraction Of Steel Sheet Pile

Care must be taken to make sure that there is adequate access for the extraction plant including any craneage required to handle the equipment and piles.

Extraction of steel sheet pile.

A pile that has met an obstruction or that has split or broken in driving or that is to be salvaged steel sheet piles are frequently salvaged for reuse is usually pulled extracted. This compact versatile and very powerful extractor consists of two hydraulic cylinders capable of generating up to 4 000 kn 450 ton of pile extraction force through a set of hydraulically actuated taper wedge jaws. Incomplete installation of the pile to the projected mark is eliminated by one two fold raising of the sheet pile by 0 5 0 8 m and its subsequent reinstallation. Increasing pressure within the foundation industry to find means to extract previously driven steel piles without creating any noise or potentially damaging vibrations led to the development of the universal pile extractor.

This can be achieved by either using silent or vibratory equipment. Passage of the sheet pile below the projected mark is corrected by its building up or plating. Pull the pile as soon as possible after driving it. The longer the pile stays in the soil the more compact the soil becomes and the greater will be the resistance to pulling.
