Abstract (en)
Method of making a tunnel tube with the aid of a tunnel drilling device, particularly for car or train traffic, with a diameter of preferably 3m to a minimum, particularly at least partly below the local ground water level in sandy soil or another relatively easy processable underground, such as clay, peat, gravel or mixtures of these soil types, by initially making one or more at least substantially parallel guide or pilot drillings which are subsequently followed by the tunnel drilling device. <IMAGE>
