Horfield Cutting Gabions

The Great Western Route is undergoing a period of modernisation with the upgrading of infrastructure to make journeys faster and services more reliable. Part of this scheme is the Horfield Cutting where an extra lane is being added to ease a bottle neck in the rail system. MJ Church, the civils contractor for Main Contractor Vinci Construction, contracted Phi Group to install a gabion retaining wall nearly 1,000m long and up to 5.0m high in places.

Woven mesh gabion baskets were originally specified by the Client, but Phi Group proposed they be changed to the welded mesh gabion baskets that are quicker to install. The baskets are then filled with 6G gabion stone to give them the required mass. Upvc sleeves were installed within the baskets as they were being installed, so soil nails could be installed through the baskets to further stabilise the slope once the gabions were finished. Hand placing of the gabion stone to the front face ensures a great looking finish to the gabion wall.
