winding hole excavation
The excavations for the winding hole below Devil's Hole Lock. To build the winding hole, which will be on part of the original river line before it was diverted and left the Ox-bow, we have had to remove the years of silt down to the hard clay and then build back up again using good compacted material to provide a base for the winding hole bank where it crosses the line of the old river. The red machine is a remotely controlled earth compactor. (Oct 4, 2009.).
