Beschreibung
Zusammenfassung:	The invention provides a C-shaped pipe piece splicing method which comprises the following steps that firstly, two to-be-spliced C-shaped pipe pieces are provided, and each C-shaped pipe piece is provided with two splicing ends; secondly, two sealing strips are attached to the splicing seam of every two adjacent C-shaped pipe pieces in the vertical direction; thirdly, the two C-shaped pipe pieces are spliced on the splicing pedestal, and a grouting space is defined by the two splicing ends and the two sealing strips; fourthly, sealing binders are smeared on the outer sides of the two sealing strips correspondingly, and heat preservation maintenance is conducted for preset time; 5, after the strength of the sealing binder meets the set requirement, grouting operation is carried out, and heat preservation and maintenance are carried out for preset time after grouting operation is completed; and sixthly, after the grouting material reaches the preset strength, splicing of the C-shaped duct piece is completed.
