A drill frame or drill platform 1 is allocated to a ship caisson 6 in order to allow bore holes 12, 13 to be driven, for example, into the bottom of a lake 11. Since said bore holes 12, 13 must subsequently be filled with explosives, the use of several drill tools 25 of different design is necessary and possible because a rod magazine 20 comprising several different drill tools 25 is allocated to said drill frame 1. It enables simple and rapid replacement because a conventional clamping device 29 and clamping and crushing device 30 can be employed. The individual drill tools 25 are each equipped with adapters 31 of identical design so that they can be seized and actuated safely using the described clamping and drilling (sic) devices 29, 30 . For the publication FIG. 1 is provided.
