Ursula, the eastbound tunnel boring machine launched from Kirtling Street, has installed it’s 1,000th concrete ring on its journey towards Chambers Wharf in Bermondsey.
The first ring was put in place in March 2019 during the machine’s umbilical launch.
The rings are used as the primary lining for the tunnel and are made up of eight segments. Ursula will install over 3,200 more rings before the end of its drive.
Paul Hallows, Kirtling Street Site Manager, said “The 1,000th ring is a terrific milestone to reach, and it’s a great indication of how much the team has achieved. It’s been a truly collaborative effort, and everyone across the site has played a crucial role. There’s still a long way to go, and it’s important we maintain the same standards to complete the drive safely.”
All segments delivered to Kirtling Street are transported by barge. The site recently received its 100th barge of segments, with each barge movement taking around 50 heavy goods vehicles off the roads in the local area.
