arranging a prefabricated steel reinforcement framework on a bottom plate steel reinforcement of the comprehensive pipe gallery, and oppositely arranging two prefabricated formwork support frames; the template support frame comprises a transverse support sheet and a longitudinal support sheet; the transverse supporting sheet is fixed with the longitudinal supporting sheet and is vertical to the longitudinal supporting sheet; a first fixing piece extends from one end of the transverse supporting piece, which is far away from the longitudinal supporting piece; one end of the longitudinal supporting sheet, which is far away from the transverse supporting sheet, is fixedly connected with a second fixing sheet; the second fixing piece is perpendicular to the longitudinal supporting piece; a first fixing hole is formed in the first fixing sheet; a second fixing hole is formed in the second fixing sheet; the first fixing hole corresponds to the second fixing hole;
attaching the first fixing hole of one formwork support frame to the second fixing hole of the other formwork support frame, attaching the second fixing hole of one formwork support frame to the first fixing hole of the other formwork support frame, penetrating a fixing stick into the attached first fixing hole and second fixing hole to form a formwork, and fixing the formwork on the steel bar framework;
pouring concrete into the template to enable the template to limit and shape the concrete so as to form template concrete;
and removing the formwork on the formwork concrete to form the cast-in-place buttress.
