Method and device for driving a series of sheet pile planks into the ground

摘要

A device for carrying out the method for driving a series (1) of sheet pile planks (4) into the ground comprises individual drive-in means (8) for individually acting on at least two sheet pile planks (4), and pressure means (11,12,13) for supplying fluid to the individual sheet pile planks at excess pressure. The pressure means are designed for optionally dispensing fluid (19) either at a relatively high pressure and/or a relatively high flow rate, on the one hand, or fluid (18) at a relatively low pressure and/or a relatively low flow rate, on the other hand. Control means are provided for activating the drive-in means (8) associated with a sheet pile plank, for simultaneously supplying the fluid (19) at a relatively high pressure and/or a relatively high flow rate to said sheet pile plank and simultaneously supplying the fluid (18) at a relatively low pressure and/or a relatively low flow rate to the sheet pile plank which is kept stationary.
