Gabion retaining wall for Horfield Cutting
Almost 1,000m of Phi welded mesh gabions were used as part of the works at Horfield Cutting on the Great Western rail route. The gabion retaining wall is up to 5m high in places
The Great Western Route is undergoing 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 bottleneck in the rail system.
Solution
MJ Church, the civils contractor for main contractor Vinci Construction, contracted Phi Group to install a gabion retaining wall nearly 1000m long and up to 5m high.
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 were 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 exposed face ensured a great looking finish to the gabion wall.
