Extraction Of Steel Sheet Pile

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.

Extraction of steel sheet pile.

Realtop excavator mounted hydraulic vibratory pile hammer can drive and extract steel sheet pile cement pile rail pile h steel steel pipe etc. 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. 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. When piles are used as a temporary means of earthwork support they can be extracted for re use.

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. 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. Passage of the sheet pile below the projected mark is corrected by its building up or plating.
