Geothermal energy pile / foundation

摘要

A technique for installing geothermal pipe-work 7 in foundation elements such as piles involves the use of a coupling means 11 to couple said pipe-work 7 to a longitudinal installation member 8 . This allows said pipe-work 7 to be plunged into wet concrete so as to install the pipe-work 7 to a required depth upon which point the installation member 8 may be decoupled and retrieved. The technique is said to be useful in forming geothermal piles by continuous flight auger techniques.
