Problems solved by technology

Beam prefabrication requires temporary use of land to build related prefabrication yards. As environmental protection requirements become higher and higher, temporary land acquisition is also more difficult, and generally different forms of beam body prefabrication yards are different. Increasing prefabrication yards will not only increase construction costs, but also Not conducive to environmental requirements

Abstract

The invention discloses a construction method for changing a prefabricated T beam into a multi-span prefabricated box beam pedestal. The construction method comprises the following steps: a, cleaning a pedestal; b, performing foundation expansion construction; c, chiseling the concrete; d, binding reinforcing steel bars; e, constructing an embedded part; f, performing template installation; g, performing concrete pouring and vibrating; h, performing concrete surface finishing; i, performing steel plate installation; and j, checking and accepting the pedestal. Beam system work of different structural forms can be completed in a predicted site, temporary land is reduced, cost is saved, the construction requirements can be met by directly widening the two sides of the pedestal on the basis of an original pedestal, materials are simple, and construction is convenient and fast.

Description

technical field [0001] The application relates to the technical field of bridge widening, in particular, to a construction method for changing a prefabricated T-beam into a multi-span prefabricated box girder pedestal. Background technique [0002] In order to improve the construction efficiency, save a lot of construction time and ensure the quality of construction, the current road and bridge engineering construction, such as bridge girders and other components are produced by prefabrication methods, transported to the construction site for assembly and corresponding construction, which greatly improves It not only improves the construction efficiency, but also ensures that the project quality meets the design requirements. Beam prefabrication requires temporary use of land to build related prefabrication yards. As environmental protection requirements become higher and higher, temporary land acquisition is more difficult, and generally different forms of beam body prefabr...
