Abstract (en)

[origin: EP0955444A2] The outer wall (20) of the building (10) is drilled through, using a drilling device with a controllable rock and concrete drill head. A completely controlled bore is made up to the main conduit (16). The conduit to be laid is connected to the drill rod (42). The drill rod is then drawn backwards to the drilling apparatus until the conduit in the building is reached. The bore crown for concrete and rock drilling can be replaced by one (38) for soft soil which is remotely controlled. The main conduit (16) is accessible via a connecting ditch (28).
