Tunnelling-Induced Ground Movements
The Canadian Geotechnical Society (CGS) is hosting a seminar on this topic on April 28. You can access the information by clicking here.
We recently completed a large project with our MiniProbe machine installing settlement monitoring points, surveying benchmarks and other related infrastructure in connection with a large utility installation project. The equipment we installed in our boreholes could be used by engineers and surveyors to monitor the potential for ground movements caused by the large tunnelling equipment used for installing the utility line. The installation of approximately 200 locations required a small drill in order to access very difficult areas and restrict the ground disturbance as much as possible. Although we did not use the direct push soil sampling feature of this machine, its ability to auger allowed us to install the points at a range of depths. The very light weight and “tread lightly” features of the machine were a perfect fit for these installations. We have now done a number of projects involving settlement monitoring with this drill; it’s proving to be a very versatile small drill.
One of the advantages of working with Kodiak drill crews is that we try to minimize the time spent on the job site, filling out the Provincial record that is required when groundwater monitoring wells are installed. That time savings reduces your drilling costs. Since drill crews – from any company – charge out at a substantial hourly rate, the savings can be appreciable.
