Abstract

The invention relates to a cast-in-place wet joint construction method and a bridge structure. The cast-in-place wet joint construction method comprises the following steps that bridge decks are prefabricated, and wet joint bottom plates are arranged on the two opposite sides of each bridge deck; the bridge decks and steel longitudinal beams are erected as a whole; a gap between every two adjacentbridge decks is filled; and concrete is poured on the wet joint bottom plates to form wet joints. According to the cast-in-place wet joint construction method and the bridge structure, the wet jointbottom plates prepared in advance can serve as the bottom dies of the cast-in-place wet joints, the workload of mounting and dismounting of the wet joint concrete bottom dies is reduced, and thereforeconstruction is convenient, and the workload is small.

Description

technical field [0001] The invention relates to the technical field of bridge engineering construction, in particular to a construction method of a cast-in-place wet joint and a bridge structure. Background technique [0002] With the development of bridge construction in our country, bridge industrial prefabrication and assembly technology has become an effective method to ensure the construction quality of bridge construction and shorten the construction period. [0003] In the related art, the wet joint is a key part of the prefabricated bridge deck, and the usual construction of the wet joint is to use tie rods to hoist the bottom form, and then install the side form to pour concrete to form the wet joint. However, this traditional construction method requires the installation of a bottom form, and the bottom form needs to be removed after the concrete reaches a certain strength. The installation and removal of the bottom form requires a construction platform, which is n...
