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

Abstract

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.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a bridge deck drainpipe bushing mold and a using method. Background technique [0002] The bridge deck drain pipe is an important part of the bridge superstructure. It can drain the bridge deck water to the outside of the bridge, protect the bridge deck structure and facilitate the driving of vehicles. [0003] The installation of the bridge deck drainpipe generally needs to reserve the drainpipe channel on the bridge deck when the bridge deck structure is prefabricated or cast-in-place. Therefore, the diameter of the drain pipe hole will be larger than the outer diameter of the drain pipe, and then the bushing concrete will be poured between the drain pipe hole and the outer wall of the drain pipe, which can be used to adjust the installation position of the drain pipe, and It can seal the gap between the periphery of the outer wall of the drain pipe and the hole of the drain...

AI Technical Summary

Problems solved by technology

This construction method is labor-intensive and material-intensive, and the economy of drainpipe installation is relatively poor, and the labor intensity of workers is also relatively large.

At the same time, due to the two-step construction of the drain pipe, the gap between the outer wall of the drain pipe and the lining concrete still exists to a certain extent, and the phenomenon of seepage water polluting the bottom plate of the bridge deck and dripping under the bridge is unavoidable
