Problems solved by technology

Because the physical properties of concrete and steel are very different, it brings great difficulties to the construction of the steel-concrete joint section.
At present, there is no mature and reliable method for the construction of the steel-concrete joint section. In the specific construction, it is usually constructed while exploring and trying. Not only the construction quality is difficult to guarantee, but also the construction period is easy to be delayed.

Abstract

The invention relates to a bridge steel and concrete mixing section constructing method. The method comprises the following steps of: (1) arranging a bottom mould of the steel and concrete mixing section; (2) binding bottom board reinforcing bars, and installing a prestress pipeline; (3) installing a side mould bracket and a side mould; (4) performing primary concrete pouring on the steel and concrete mixing section; (5) installing an inner ejecting mould of the steel and concrete mixing section; (6) binding top board reinforcing bars, and installing a prestress pipeline; (7) performing secondary concrete pouring on the steel and concrete mixing section. The invention has the advantages of simple and reliable method, high construction speed and guarantee of construction quality.

Description

technical field [0001] The invention relates to a bridge construction method, in particular to a bridge steel-concrete joint section construction method applied to the construction of a large-width bridge steel structure and concrete structure joint section. Background technique [0002] With the continuous development of domestic bridges, the combination of steel box girder and concrete box girder has been widely used, and the steel-concrete combination section is the transition section of the two structures. The construction quality of the steel-concrete joint plays an important role in the quality of the bridge. Because the physical properties of concrete and steel are very different, it brings great difficulties to the construction of steel-concrete joint section. At present, there is no mature and reliable method for the construction of the steel-concrete joint section. The specific construction is usually carried out while exploring and trying. Not only is it difficul...
