A new tunnel formwork system from Pilosio reduces the time needed for assembly. Made from standard components, this can be used for a wide range of geometries.
The Bauer subsidiary MAT Mischanlagentechnik, known for microtunneling technology, has entered the large-diameter tunnelling market with its BE-2550 separating plant in Switzerland.
The double-track Eppenberg tunnel in the Swiss canton of Solothurn is about 2.6 km long and is one of the busiest railway routes in Switzerland. Since November 2016, a 2,400tonne tunnel boring machine measuring around 115m long and 12.75m in diameter has been drilling through the mountain. The machine has been operating in the
The Terfener Innbrücke reconstruction in the Inntal valley started in 2018 and is currently one of largest bridge construction projects in western Austria. In addition to providing planning services and onsite support, Peri has used its VBC Balanced Cantilever Carriage for the first time in Central Europe.
A diverse array of new tunnelling technologies will help boost productivity and cut project costs, while boosting quality - Mike Woof writes
The worldwide market for tunnelling projects continues to be strong, with a series of major projects underway or planned for the future. These good market conditions have helped fuel research and development in new tunnelling equipment, designed to be more productive, more efficient and more reliable and able to deliver a higher quality of work.
Drilling and blas
A wealth of major road tunnel construction projects and significant cant ITS installations within existing key road tunnels have been recently completed or will soon be underway. Guy Woodford examines some of them. A state-of-the art Tunnel Boring Machine (TBM) - the 10th largest ever to be built worldwide will be put to work later this year on New Zealand Transport Agency’s landmark Waterview Connection project in Auckland. The giant Herrenknecht-manufactured machine will be used to construct the twin 2.5
