Open-Face Shield

Reinforced concrete pipes are advanced by a so-called jacking station. A steerable shield machine situated in front of the first reinforced concrete pipe ensures accurately driven pipe. This process is suitable for pipe sizes of up to DN 3200. Material is generally removed mechanically at the ‘open face shield.

Under certain circumstances, the soil may have to be stabilised (e.g. through prior injection of a pipe sleeve). VTG has extensive specialised knowledge in this area and plans and supervises the execution of the corresponding actions.
