Abstract (en)
[origin: EP2351903A2] The method involves transporting drill pipe sections (20) for extending a drill pipe by a transport unit individually one after another from a drill pipe supply area through a shaft access opening (16) into a shaft structure. The drill pipe supply area is arranged outside of the shaft structure. The drill pipe sections are introduced in a receiving area (58) of a shaft drilling device (14) with the help of the transport unit. An independent claim is also included for an arrangement for manufacturing or expanding bore or for replacing a pipeline.
