Bushing mold for drain pipe of bridge deck and method for applying bushing mold

The invention discloses a bushing mold for a drain pipe of a bridge deck and a method for applying the bushing mold. The bushing mold is used as a bridge construction auxiliary mold for bushing mortar between a reserved drain pipe pore passage of a poured bridge deck slab and the outer wall of the drain pipe and structurally comprises a central tube, a central draw bar, a bundle tube, a plurality of diagonal braces, a plurality of mold plate struts, a folding mold plate, a bottom nut, a sleeve, a barrier, a support ring, a connecting plate and the like. The bushing mold and the method have the advantages that an existing method for constructing an existing drain pipe in two steps is mainly replaced by the method for applying the bushing mold, bushing concrete is replaced by the bushing mortar with quick solidification and micro-expansion functions, and the bushing mold and the bushing mortar are used with each other, so that mounting of the drain pipe in the drain pipe pore passage can be effectively improved, and problems that a bottom plate of an existing bridge deck is polluted by water which seeps from the existing drain pipe and the water leaks to spaces under a bridge can be solved; the bushing mold is simple in structure, convenient to use and high in integration, labor and materials can be saved, effects of saving energy and protecting environments can be realized, the bushing mold and the method have high popularization and application value, and the like.
