Construction method based on UHPC bridge deck pavement whole-width paving
The invention discloses a construction method based on UHPC bridge deck pavement whole-width paving. The construction method comprises the steps that S1, shot blasting is conducted on a bridge deck; s2, anti-corrosion coating is conducted; s3, shear nails are welded; s4, mounting a reinforcing mesh; s5, paving the ultra-high performance concrete; and S6, ultra-high performance concrete shot blasting is carried out. According to the method, the transportation distance of UHPC concrete transportation is reduced, front and rear fields are matched more smoothly, meanwhile, the problem that a half-range lane needs to be reserved during concrete transportation is solved, whole-range paving is achieved, the paving flatness is guaranteed, the slope of a paved bridge deck meets the design requirement, automatic film covering maintenance is utilized, and the maintenance efficiency is improved. Automatic film covering is achieved immediately after paving is completed, and the problems that wind on a bridge floor is large, and UHPC is prone to water loss and cracking are solved.
本发明公开了一种基于UHPC桥面铺装整幅摊铺的施工方法，包括，S1：桥面抛丸；S2：防腐涂装；S3：剪力钉焊接；S4：钢筋网安装；S5：超高性能混凝土摊铺；S6：超高性能混凝土抛丸。本发明减少了UHPC混凝土运输的运距，使前后场配合更加流畅，同时避免了混凝土运输时需要预留半幅车道的问题，实现了整幅摊铺，同时保证了摊铺的平整度，使摊铺后的桥面坡度符合设计要求，利用自动覆盖薄膜养生，实现了摊铺完成后立即自动覆膜，解决了桥面风大、UHPC易失水开裂的问题。
