Abstract

The invention discloses a bridge deck construction method, a bridge deck and a bridge, and relates to the field of design and construction of composite structure bridges. The bridge deck is a UHPC-NC bridge deck slab provided with two UHPC sections and one NC section, and the NC section is located between the two UHPC sections. In the manufacturing process of the UHPC-NC bridge deck slab, UHPC and NC are poured synchronously, so that the boundary of the two materials is properly fused and has no cracking risk, the problem that the UHPC-NC bridge deck slab is prone to cracking can be solved, the overall comfort of a bridge is improved, and the service life of the bridge is prolonged. In addition, the UHPC sections are located at the two ends of the UHPC-NC bridge deck slab, due to the fact that the strength of the UHPC sections is high, the problem of retraction of the prestressed tendons can be solved, and therefore the overall structural stability of the UHPC-NC bridge deck slab is guaranteed.

Description

technical field [0001] The present application relates to the field of composite structure bridge design and construction, in particular to a construction method of a bridge deck, a bridge deck, and a bridge. Background technique [0002] With the vigorous development of standardized and industrialized construction technology in my country, the application of precast concrete bridge decks in steel-concrete composite beams and prestressed concrete composite beams has become more and more extensive. The prefabricated bridge deck generally adopts the construction method of factory prefabrication and on-site hoisting. Factory prefabrication can ensure the binding accuracy of the steel skeleton and the quality of concrete pouring. After the on-site hoisting in place, only a small amount of wet joints need to be poured, which greatly reduces the on-site wet joints. work to improve construction efficiency. [0003] In the prior art, prefabricated concrete bridge decks are often us...
