Earth loop installation with sonic drilling

摘要: A method for installing a heat exchange pipe loop in borehole, the at least certain aspects, including drilling borehole with sonic drill system having head and casing connected thereto, shoe on lower end of movable by to pumping fluid (e.g., water fluid) into casing, out through up earth surface an annular space so that drilled material flows surface, lowering down introducing grout around loop, extracting from borehole.
