HS2 Chiltern Tunnel North Portal

Описание к видео HS2 Chiltern Tunnel North Portal

Four months since the last video at South Heath (Bucks) in August where they had just started preparing the formwork for the porous portal structure on the up line and a concrete batching plant has been installed and is supplying the concrete to build them. The structures are designed to reduce sonic boom when a high speed enters a tunnel.
Tunnel bore completed in spring 2024 but work continues internally on 38 cross passages and walkways.
