A timber heading is a tunnelling process which is implemented in circumstances, such as in this case, where there is a major highway in the line of the works, and congested services in the area. therefore making an open cut trench and excavation by machine high risk and highly disruptive.
The tunnel is dug by Tunnelling Operatives using pneumatic tools, and spoil material transported out of the heading in skips on rail bogies running on the track.
The skips are then lifted out of the shaft and spoil transferred to stockpile for subsequent disposal.
This tunnel houses a new foul drainage line connection for the Wellington Place Complex in Leeds into the existing network in Whitehall Road.
