ABSTRACT:
The present invention discloses a system and method for simultaneously installing a pipe loop and a grout pipe in a wellbore. In another aspect such a system is then used to grout the wellbore by releasing the grout pipe from the pipe loop or from a bottom member connected with the pipe loop and then introducing grout through the pipe into the wellbore as the grout pipe is removed upwardly from the wellbore. In another aspect a drilling-grouting system is provided with which while one hole is being drilled a previously-drilled hole is being grouted.
