Stabilisation of collapsed shaft at Strood tunnel

This article describes stabilization efforts for a collapsed tunnel shaft and the Strood and Higham tunnel lining project in North Kent, England. After a hole 12 meters in diameter and 11 meters deep appeared in 2000 at an apple orchard, work was initiated to reinstate the ground to its original profile and ensure that there would be no additional load to the existing tunnel lining as well as no encroachment on the tunnel profile. Thirty meters below the surface was a brick-lined tunnel originally constructed as a canal tunnel in the early 1800s. The article describes how, in six stages, the collapse was repaired using cavity grouting, steel channels and rock bolts, permeation grouting, compaction grouting, foam concrete and finally, chalk fill and topsoil.
