respect to one another along a central axis 13 with an intermediate space 8 being present between the pile element 2 and the tube 5 in the illustrated embodiment the pile 2 and tube 5 is of a substantially cylindrical design in other embodiments not shown the tube may of course have another shape provided that an intermediate space is formed between the outer and inner wall which can reduce the transmission of noise or vibrations to the environment the tube 5 is preferably made from steel walls the structure of the tube may be self supporting which means that no separate supporting structure has to be provided in order to keep the tube in its vertical position fig1 shows that a centre system 11 is provided at the top of the tube 5 here the centre system 11 is schematically depicted in practice several centre systems 11 may be arranged along the length of the pile 2 for centring and aligning the pile 2 with the tube 5 this centre system 11 ensures that the source of sound being the pile 2 while being hammered down by hammering installation 1 remains centred in the tube 5 which is an optimal position in view of noise dampening the diameter of the pile 2 can vary along its length therefore the centre system is adjustable so that this variation can be allowed and in addition any intended narrowing and or widening of the pile 2 can be accommodated by the centre system the pile 2 may for example have a tapered section or sections of different cross section like a telescopic pile the dimensions of the centre system vary depending on the dimensions of.
