The invention discloses a prefabricating construction method for a pi-shaped beam of an ultra-high performance concrete pedestrian overpass. The method comprises the steps of (a) pedestal and bottom die installation, (b) side die and corrugated pipe installation, (c) vibration motor installation, (d) end die and anchor bearing plate installation, (e) transverse connecting steel plate installation,(f) concrete pouring, (g) curing agent spraying and moisturizing film covering for maintenance, (h) segmental beam die removal, (i) high-temperature steam maintenance, and (j) segmental splicing andtensioning. The ultra-high strength and the ultra-high toughness of the ultra-high performance concrete are brought into full play, through structural optimization design, the whole bridge is quite attractive in appearance, meets the urban attractiveness design requirement and becomes quite light, large hoisting equipment is not needed in the construction hoisting process, the occupied road spaceis small, rapid construction can be achieved, and the construction cost is reduced. The influence on urban traffic is small, all sections of beams are directly assembled, cast-in-place is not needed,and the construction speed is high.
本发明公开一种超高性能混凝土人行天桥π型梁预制施工方法，包括步骤：（a）台座及底模安装、（b）侧模及波纹管安装、（c）振动电机安装、（d）端头模及锚垫板安装、（e）横向连接钢板安装、（f）混凝土浇筑、（g）喷洒养护剂及覆盖保湿膜养护、（h）节段梁拆模、（i）高温蒸汽养护、（j）节段拼装、张拉，本发明充分发挥超高性能混凝土超高的强度、超高的韧性通过结构优化设计，使得整个桥梁不仅在外观上十分美观符合城市美观设计要求，且整个桥梁变的十分轻盈，在施工吊装过程中无需大型吊装设备，占用道路空间小且能快速施工，对城市交通影响小，各节段梁直接装配，无需现场浇筑，施工速度快。
