US Patent No: 6679655

Permafrost support system and method for vacuum-insulated pipe

---

Abstract

---

A system for supporting pipe within soil or fill material which minimizes positional disturbances of the pipe despite seasonal fluctuations in atmospheric temperature is provided. The system provides a length of double walled pipe, a support member placed in the soil or fill material and a wicking device which transfers energy between the inner pipe of the double walled pipe which is typically full of a cryogenic fluid and the support. The energy transfer stabilizes the soil or fill material, typically by freezing.
