Crossrail completes first tunnel 'breakthrough' August 2012
Показать описание
Crossrail has successfully completed it's first tunnelling "breakthrough" at our Limmo Peninsular worksite, near Canning Town.
The "breakthrough" took place at the end of August when our eastern tunnels contractor drove the first of two 58m SCL (sprayed concrete lining) tunnels connecting the main Limmo shaft to the auxiliary shaft.
The newly constructed tunnel is teardrop shaped with an average diameter of 8.2m. Approximately 45 metres below ground the tunnel connects the two huge launch shafts, creating the space to build the TBMs underground.
Elizabeth and Victoria (our third and fourth TBMs) will be lowered in sections into the Limmo main shaft and assembled underground, before starting their 8.3km (5.16 mile) journey towards Farringdon.
