– Shaft Sinking
This technique can be carried out in two different ways, either by jacked caissons or underpinning. These two methods can be used regardless of the size of the shaft.
This method is used for the installation of pipelines and uses powerful hydraulic jacks to push pipes through the ground behind a shield. This method is most commonly used for crossings under small roads and rivers.
Timberheading is a manual tunnelling method, excavated by hand with the use of timber boards for ground support after the tunnel has been manually excavated. This method is ideal for connecting services with minimal disruption.
