Abstract (en)
A method for producing an underground passage comprises the steps of: - providing a driving device (4), - providing a pipe section (3,8), - driving the pipe section (3,8) into the subterranean ground (6) by means of the driving device (4), - removing from the pipe section (3,8) the soil material that has gone into the pipe section while it is being driven into the subterranean ground (6). The method is characterized by the use of a pipe section (3,8) whose height measurement is less than the width measurement.
