Zusammenfassung:	The utility model provides a heat preservation device for a C-shaped duct piece splicing process. The heat preservation device comprises an isolation cover (10), a warm air blower (20) and a control device (30). The isolation cover (10) can cover the periphery of the splicing seam of the C-shaped duct pieces, so that a closed space is formed around the splicing seam of the C-shaped duct pieces; the warm air blower (20) is arranged on the isolation cover (10), and an air outlet of the warm air blower (20) leads to the interior of the isolation cover (10) and is used for conveying warm air into the closed space; the control device (30) is electrically connected with the warm air blower (20) so as to control the warm air blower (20) to work. By arranging the isolation cover and the warm air blower, a closed space with relatively constant temperature can be provided, and the temperature of the closed space can be adjusted by combining the control device with the warm air blower, so that the solidification time of
