[0042] (1) According to the specific range of slope construction and dust suppression demand, the number of extension pipes 31 needed to be used is determined, the required number of extension pipes 31 is taken out, and splicing is prepared. The right end of each extension pipe 31 is inserted into the splicing hole along the fixed threaded sleeve 391, so that the extension pipe 31 enters the splicing box 33. When the splicing threaded sleeve 392 is attached to the end face of the fixed threaded sleeve 391, the extension pipe 31 is inserted into place.
