SECONDARY LINING COMPLETED ON TIDEWAY GIANT SHAFT

摘要

Tideway - London's so-called 'super sewer' - has notched up another milestone: the secondary lining of the 49m-deep shaft at Albert Embankment has been completed.Around 1,800m~3 of concrete and 400t of steel reinforcement were required to create the 14 ascending shutter lifts. The team will now continue to finish the heading beam at the top of the shaft and begin construction of the wall which will form the perimeter of new public space to be created on the riverside.The Albert Embankment shaft is one of three giant structures that will connect London's ageing Victorian sewer system to the new deep-level super sewer. The other two shafts are at Heathwall Pumping Station (28m deep) and Victoria Embankment (48m). Base slabs for the shafts are up to 3m thick and were created by continuous concrete pours to ensure consistent quality.
