- the drill pipe 10 At its front end 13 'and at its rear end 14', the drill pipe 10 "has a connecting flange 15 'For this purpose depressions 17' are embedded in a wall 16 'of the shuttering element 1 1', 12 'corresponding to the depressions 17'. bores 18 'are provided, into which connecting bolts 20' can be inserted, which are screwed together with nuts 19 ', thereby producing a frictional connection between the individual drill pipes 10 ". In a recess 21 'provided in the flange 15' in the region of the bores 18 ', a seal (not shown) can be introduced.
- connection of the drill pipes 10 "can take place in a form-fitting manner, for example by means of engagement elements.”
- a simple release of the drill pipes from each other after removal is not readily possible 'Provided that serves as a point of application for the introduction of force for Voriden or retraction of the drill string 1 10 via the feed unit 103'.
- the wall 16 'recesses 23' are provided which are bounded by a web 24 'on one side.
- the web 24' holes 25 ' are provided in the recesses 23 'and the web 24' holes 25 'are provided. This is also a flange-like connection for the formwork elements 1 1 ', 12', which are arranged on top of each other.
- a mounting device 400 This comprises, as shown in FIGS. 13 to 19, a frame 410 in which a feed region 430 and a mounting area 420 are provided.
- the supply region 430 comprises an outer region 440 and an inner region 450.
- a drill pipe 10 ", which consists of two formwork elements 1 1 ', 12' is assembled but not yet locked is arranged on a carriage 460, which is movable on the guide elements 470 from the outer region 440 in the inner region.This position is shown in Fig. 13.
- the mounting device 400 here comprises two handling elements 500, 510.
- the upper handling element 500 and the lower handling element 510 are each arranged to be vertically movable on the frame 410.
- the upper handling element 500 comprises gripping elements 520 which grip the upper formwork element 12.
- the lower handling element 510 comprises a support 530, on which the lower formwork element 1 1 'rests.
- the drill pipe 10 is then possibly rotated, moved toward and connected to the drill hole 102 'against the drill string 110. All components of the apparatus 400 then release the drill pipe 10" and the drill string 110 is moved by the feed unit 103'. pressed into the borehole 102 '.
