Harbour Road, Cove
Client: Cove Harbour Conservation Trust Ltd
Main Contractor & Anchor Installer: Holequest Ltd
Access to this coastal area of outstanding natural beauty was being severely hampered due to the erosion of the sea cliffs spilling across the roadway. If left unchecked it was feared that the erosion would not only take the road completely but soon also damage the upper pathway and endanger the houses of this small village. Remedial work to rebuild and stabilise the slope with minimum disruption was required.Solution:
A two tiered approach was taken, firstly to protect the upper edge of the roadway by installing a cost effective but naturally sympathetic retaining wall of recycled telegraph poles. To add support to the vertical sections of the retaining wall two rows of anchors were installed into the embankment and once loadlocked into position the tendons were then wrapped around the timber post and firmly secured with rope grips.
Then to protect the lower edge of the roadway anchors were installed and loadlocked into the cliff face itself. The whole affected area was covered with Maccaferri MacMatR as this would help spread the anchor load across the surface as well as retain the thin topsoil so aiding the re-vegetation process. Finally, load plates were used to hold everything in situ.
Anchor System: 53 x S08EC galvanised spheroidal graphite iron anchor c/w 6m of 8mm Ø stainless steel wire tendon and finished with 3 x stainless steel rope grips. 55 x S08EC galvanised spheroidal graphite iron anchor c/w 6m of 8mm Ø stainless steel wire tendon, finished with a Grade 316 200mm x 200mm stainless steel load plate and 8mm stainless steel wedge grip.
Anchor Design Life: 30yrs
Soil Type: Sandy gravely clay
