A 1,200-tonne concrete ‘lid’ has been lifted onto the top of a deep shaft in Stratford, east London – marking the completion of the Tideway ‘super sewer’ construction.
The 24m-wide circular concrete ‘lid’ was lifted into position at Abbey Mills Pumping Station using a purpose-built gantry crane and other manoeuvring equipment.
The operation took around five hours and was the heaviest lift on the whole super sewer project.
The shaft at Abbey Mills is the deepest on the project at 70m, the point at which the super sewer connects to the Lee Tunnel, which was completed in 2016.
