What we are doing
Excavation and Reinforced Concrete Works in Wormwood Scrubs
We will be excavating a launch shaft to prepare the area to launch the micro-tunnelling machines. As part of this work, we will also be installing concrete structures in the ground to enable the micro-tunnelling to be carried out.
To complete this work an excavator will dig to the pit. All material will be removed from site using tipper lorries. Once the excavation is complete, we will install a concrete base slab with front and back walls.
Micro-tunnelling works in Wormwood Scrubs
Once the shaft is complete, we will be installing eight micro-tunnels, which will run from the launch chamber in Wormwood Scrubs site underneath the railway tracks to the reception chamber in the main site. These micro-tunnels will be used to divert the services along Old Oak Common Lane. This diversion is needed to allow us to lower Old Oak Common Lane that is planned in the future.
