Construction method of bridge deck slab, bridge deck slab and bridge
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.
一种桥面板的施工方法及桥面板、桥梁，涉及组合结构桥梁设计和建造领域。本申请的桥面为具有两个UHPC段与一个NC段的UHPC‑NC桥面板，并且NC段位于两个UHPC段之间。在UHPC‑NC桥面板的制作过程中，UHPC和NC同步浇筑，使两种材料的分界处存在适当交融，两种材料的分界处无开裂风险，可以解决UHPC‑NC桥面板容易开裂的问题，从而提升桥梁整体的舒适性和使用寿命。此外，UHPC段位于UHPC‑NC桥面板的两端，由于UHPC段的强度高，可以弥补预应力筋回缩的问题，从而保证UHPC‑NC桥面板的整体结构稳定性。
