<p>A multi-function portable well boring machine that contains the components for geothermal loop installations including drilling the geothermal well, installing the geothermal pipe and grouting the well after the geothermal pipe is installed in the well. The well boring machine is mounted on a rubber wheeled tractor type base. There is a drilling mast that pivots from a horizontal position to a vertical drilling position. A water recycling tank is mounted on the rear of the machine and pivots from its upright stored position to a horizontal position. Water is recycled for the drilling operation to minimize the amount of water discharged to the surrounding area. The geothermal pipe is installed into the well bore by means of a grouting tool that injects grout into the well bore to seal the well as the grouting tool is withdrawn from the well bore.</p> |
