AN ARRANGEMENT FOR SUPPORTING A STEEL PILE IN AN IMPACT PILE DRIVING DEVICE, AN IMPACT PILE DRIVING DEVICE, AN IMPACT PILE DRIVING MACHINE, AND A METHOD FOR ARRANGING THE SUPPORT OF A STEEL PILE IN AN IMPACT PILE DRIVING DEVICE

摘要

The invention relates to an arrangement forsupporting a thin-walled steel pile (5; 17; 26; 35) in an impactpile driving device, the arrangement comprising a supportingsurface (4; 14; 23; 31), to which the steel pile (5; 17;26; 35) can be supported, and in which arrangement thesupporting surface (4; 14; 23; 31) is provided with one or moreabsorbing surfaces (6; 16; 25; 33) to be placed against the endof the wall (8; 18, 26; 36) of the steel pile (5; 17; 26; 35). Inthe arrangement according to the invention, the absorbingsurface (6; 16; 25; 33) is configured to shape the end of thewall (8; 18; 27; 36) of the steel pile (5; 17, 26; 35) comingagainst the absorbing surface (6; 16; 25; 33), by the effect ofthe impact driving of the steel pile (5; 17; 26; 35), so that atleast the part of the wall (8; 18; 27; 36) at the absorbing surface(6; 16; 25; 33) of the wall (8; 18; 27; 36) is shapedagainst the absorbing surface (6; 16; 25; 33), wherein themovement of the wall (8; 18; 27; 36) in the direction of aplane transverse to the direction of impact driving of the steelpile is prevented, at least at the head of the steel pile (5; 17;26; 35). Also, the absorbing surface (6; 16; 25; 33) in thesupporting surface (4, 14; 23; 31) can be configured to beshaped by the effect of the impact driving of the steel pile (5;17, 26, 35) so that the absorbing surface (6; 16; 25; 33) isshaped against the part of the wall (8; 18, 27; 36) of the steelpile (5; 17; 26; 35) at the absorbing surface (6; 16; 25; 33),whereby the movement of the wall (8; 18; 27; 36) at the headof the steel pile (5; 17; 26; 35) is prevented. The inventionalso relates to a method for arranging the support of a steelpile (5; 17; 26; 35) in an impact pile driving device.
