description	The utility model discloses a drill used for pre-reinforcing the grout injecting big tube shed at the bad geology section such as lanky stone wall rock when the underground project is started. The utility model is a wing panel type chambering sleeve and tube drill, which consists of a drill bit 2, a tube boot 4, a sleeve 5 and a drill rod 7. The utility model has the technical characters that the utility model still comprises a chambering wing penal 1 which is symmetrically arranged on the top face of the drill bit 2; the top face of the drill bit 2 is opened with a plurality of grooves which can make the chambering wing panel 1 rotate; when the drill bit rotates withershins, the chambering wing panel 1 rotates taking a fixed shaft core as the center and then uncloses positively and chambers; here, the chambering diameter is bigger than that of the sleeve 5; when the drill bit 2 rotates deasil, chambering wing panel 1 rotates taking the fixed shaft core as the center and returns and shrinks by rotating wither
