What we are doing
Wormwood Scrubs micro-tunnelling
A 1.2 m pipe will need to be installed as part of Stamford Brook Sewer diversion to allow for building the Station Box foundations. The location of works is shown on the image overleaf.
To complete this work, we will be using micro-tunnelling. Micro-tunnelling is a digging technique used to construct small tunnels. This work will be completed by using a tunnel boring machine, which will be installed in Wormwood Scrubs and will be driven towards the Station Box on the Old Oak Common Station site. Only a single micro-tunnel will be installed in this part of the Scrubs. This work is needed to allow us to divert the Stamford Brook Sewer.
For safety reasons, the micro-tunnelling works will be 24/7 whilst the tunnels are under construction. This is to avoid the tunnel boring machine being stuck in the ground and causing potential settlement on the surface.
