Services Soil nailing
Project experience Slope stabilisation
Client Bowmer & Kirkland
Contractor Keller / Phi Group
 
 

Context

The development of a new unit at Logic Park Industrial Park, Leeds, required regrading of part of the sloping site and steepening of the slope to the North of the unit.

Requirement

The main contractor was keen for one geotechnical contractor to carry out the complete package of soil nailing and facing system. During the main works Keller installed soil nails to the face of the slope cut by others in a top to down sequence and Phi Group installed gabion cladding.

Challenge

Soil nail installation in very stiff clay and weathered mudstone and challenging logistics and planning.

Solution

Keller installed more than 4.5km of R32-280 hollow high yields bars. Self drilling soil nails were completed with structural mesh and head plates to support the excavated face. During the works Keller used a traditional crawler mounted drilling rig and specially adapted excavator with the drilling rig mounted on the mast. A remotely controlled drilling rig mounted on an excavator provided great flexibility to install soil nails which were located too high for a traditional crawler mounted rig. Following the soil nailing works, Keller colleagues at Phi Group installed 1200sq m of gabion cladding on the face of the slope.
