摘要

construction engineering. SUBSTANCE: device used for thermal earth stabilization at foundation foot of buildings and structures being erected in areas of seasonal and eternal frost has soil and air heat exchangers, as well as heating conduit connecting them. Novelty is that heating conduit is made composite in length; it is assembled of hollow members telescopically joined together; length of members is determined from equation given in description of invention. EFFECT: improved operating efficiency; facilitated manufacture due to provision for controlling depth of foundation. 3 cl, 2 dwg
