JACKING IN AT BRENT CROSS

The article discusses the installation of two concrete box unit tunnel sections under existing embankments at the Brent Cross flyover, London. The two tunnels are claimed to be the world's largest such units to be installed using pipe-jacking or thrust boring techniques. Each of the precast concrete units are 32 ft wide, 22 ft high and have lengths of 33 ft and 45 ft. The rear jacking capability is provided by a bank of 28 110 ton capacity hydraulic rams. /TRRL/
