Project Overview:
Ground Conditions:
Solution:
Once SC installation began, the uncontrolled fill layer proved to be tougher to drill through than originally anticipated. To penetrate this layer and make SC installation easier, Menard decided to predrill to a maximum depth of 20 ft. Due to the collapsing of the holes, at times Menard needed to predrill some of the
holes multiple times.
During insertion of the vibro probe into the predrilled holes, the uncontrolled fill layer collapsed on top of the probe, effectively trapping it. To extract the tooling without damaging the rig, Menard drilled angled holes into the collapsed fill. This loosened the material enough so that the tooling could be extracted.
Although complications with the fill layer set production back by a few weeks, the client was overall pleased with Menard’s performance and the ground improvement solution. A total of 546 SCs were installed to a maximum depth of 35 ft.
