Drilling apparatus for introducing drill-holes in ground, has drilling fluid line comprising connection-side end that is connected with coupling station that includes reactive connections for parking of inlet pipes for unused drilling fluid

摘要

The apparatus has an inner drill rod drive (24) movably arranged at a carriage (14). A drilling fluid line (30) is connected with the drive for supplying a drilling fluid into an inner drill rod (22). A coupling station (40) variably connects inlet pipes (62, 72) for the used drilling fluid. A connection-side end of the drilling fluid line is connected with the coupling station that includes reactive connections for parking of inlet pipes for unused drilling fluid. The reactive connections are arranged adjacent to the connection-side end of the drilling fluid line.
