https://lnkd.in/gv7aNyMq Tunnelling is not without its risks, the formation of sink-hole being one of them.

how much NOPE can you put in one project?

“We used EUROFLO® for our Lyttelton Tunnel project, a critical infrastructure project given the tunnel is a vital transport artery for Christchurch. We placed 2000m of EUROFLO® 315mm OD pipe. It was very easy to install as long as they were all facing the right direction when taken into the tunnel on our hi-rail truck. Over the first two-day block of time we put in 500m of pipe as there was a bit of learning for all of the team. The pipes were installed with rodding eyes every 100m or so and wrapped in bidim. Over the second two-day block of time we put in 1500m of pipe. It was possible for the pipe to be picked up and placed by one person if needed, but easier with two.” - Mike Newman, Supervisor Rail, Downer Lyttelton Tunnel Project Read more about KiwiRail's use of EUROFLO® civil pipe here: https://lnkd.in/gbMgb_Zq #euroflo #pipes #pipesandfittings #waterflow #watermanagement #stormwater #drainage #drainagesolutions #civilengineering #civilconstruction #civilcontractors #newzealand #culvert #infrastructure #innovation #stormwatermanagement #council #crossing #rail #roading

Two more ‘sinkholes’ appear above HS2’s Chiltern tunnels The "sinkholes" in South Heath are the latest to have emerged above High Speed 2’s (HS2's) Chiltern tunnels route. #sinkhole #groundcollapse #HS2 #highspeedrail #chilterns #tunnelling

As Part of the Bellingham Shipping Terminal Modernization Project the Port of Bellingham’s contractor (American Construction) has removed a section of dock at the Bellingham Shipping Terminal, and is working to remove the old dock pilings. On or around September 16th 2024, the installation of new pilings will be accomplished using both a vibratory hammer and an impact hammer. An increase in daytime noise levels can be expected during these intermittent operations (Operational hours are 7am – 10pm). When in operation, the vibratory hammer is expected to make noise and the impact hammer will make repeated loud bangs as the steel hammer hits the 155 foot long, 24 inch diameter hollow steel pile.
