General

UMBRELLA PIPE DRILLING is a system that provides structural support on the surfaces of tunnels, and machines such as the ROCK Overdrilling machine and various drilling bits are used for this process. Basic methods such as 9-meter steel pipes and selective cements are used. The construction process includes chuck forming, drilling, pipe joining and joining with special machines; This is followed by cutting goose. This support technique provides stability even to the unexcavated tunnel section and separates it from other divisions. The construction process offers a reliable solution in tunnel engineering with the use of expert machinery and the sharing of special parts.
