Abstract (en)
A method for the removal of a driven-in slender object (1), such as a pipe, a pile or a sheet pile wall plank, comprises the application of an upwardly directed tractive force to the object, and also the exertion of an impact load on the object while maintaining the tractive force. The impact load can be directed either upwards or downwards. The apparatus used for this method comprises an impact plate (9) and/or a piling cap (8) which has a ram element (10) and a hauling means (2) which can be fastened to the object and has a hydraulic press element (3,4) for the application of an upwardly directed tractive force to the object. <MATH>
