Guided Boring
The guided boring operation is a simple way of accurately installing small diameter pipes using a three pass system. The first pass is to install the pilot tubes to line and grade by using a theodolite guidance system and a led at the pilot head. The second stage is to install casings and augers and the final stage to push the line pipe and remove casing at the exit pit.
B&W own a number of Akkerman 240 GBM’s capable of installing the following pipe diameters 150mm, 225mm, 300mm, 400mm, 450mm, 500mm, and 600mm. In addition we have a 450mm and 600mm Power Cutter Head ( PCH ) which can be used for pilot tube microtunnelling in soft unstable grounds.
