A bundle of tubes (1) arranged without trenches according to a bore and swiv el method, wherein a bore channel (9) is made in a first boring step and said bore channel is widened when the drilling and swivel head (5) is removed therefrom, said bundle of pipes being drawn into the bore channel (9). The inventive bundle of pipes is characterized in that said bundle (1) is compos ed of a plurality of individual pipes (2) and flanges which are arranged lengthwise (15) at a distance from said pipes (2) and used as spacers for sa id pipes (2). The invention also relates to a method, wherein a rotational decoupling device (6) prevents the rotational movement of the bore/swivel he ad (5) produced during the removal process (9) from being transmitted to the bundle of pipes (1), and the bundle of pipes (1), supported by means of stabilizing devices (3,14,17) inside the bore channel in the same spatial position as that of the pipes (2) in relation to each other and the surrounding environment, are drawn though the bore channel.
