A method and system for installing geothermal heat exchangers, energy piles, concrete piles, micropiles, and anchors using a sonic drill and a removable or retrievable drill bit |
| abstract |
There is provided a method for drilling a cased hole and installing a micropile. A sonic drilling ap-paratus is positioned at a desired location. The sonic drilling apparatus includes a rotating and vibrating appara-tus for rotating and vibrating a drill string into the ground. A retrievable drill bit is operatively connected to the drill string. The cased hole is drilled to a desired depth by rotat-ing and vibrating the drill string into the ground. The re-trievable drill bit is retrieved from the cased hole following the drilling of the cased hole to the desired depth. A mi-cropile is lowered into the cased hole following the re-trieval of the retrievable drill bit. Grouting material may be discharged into the cased hole before or after the drill string is removed from the ground. In another embodi-ment, a removable drill bit may be used in place of the re-trievable drill bit. |
