ABSTRACT:
In a method for the trenchless laying of pipes, a drilling operation (5) is firstly carried out by means of controlled heading from a starting point (1) to a finishing point (6). Then the drilling head (3) is disconnected from the heading pipes (4) and the heading pipe run is connected by means of a special connecting pipe to the product pipe run (9), which is prefabricated above ground at the finishing point (6). Subsequently, the heading pipes (4) are drawn back from the drill hole to the starting point (1), the product pipe run (9) simultaneously being drawn into the drill hole.
