橋梁、トンネル

Werrington Grade Separation, Werrington, United Kingdom

The 160 m long tunnel was cast monolithically in a total of nine sections – with only one VTC Tunnel Formwork Carriage.
With a customised VTC Tunnel Formwork Carriage, consisting of standard components from the VARIOKIT Engineering Construction Kit in combination with GT 24 Girders and Battens in different lengths, the project requirements could be met.
In total, the tunnel was cast in nine concreting sections, each 17 m long and 8 m high. The combination of concreting sequence and the high speed of the VTC System helped to save a full ten days per cycle.
With the help of the VTC Tunnel Formwork Carriage used, both undersides and inner slabs could be quickly and safely struck at the same time.

Construction Manager

Early involvement has been saving grace with everything, including the design of the structure and formwork from PERI. We got an understanding of the proposed solution, including a sequence drawing and how it would all come together. The PERI system was so quick and simple to use – it has worked brilliantly throughout the project.
