The invention relates to an ultra-high performance concrete I-shaped beam machining method, the method comprises the steps of carrying out formwork and prestressed pipeline installation, carrying outconcrete pouring and embedded shear bar installation, carrying out curing agent spraying and moisturizing film covering for curing, carrying out formwork removal, carrying out high-temperature steam curing and the like, and therefore, the advantages of ultra-high strength and ultra-high durability of ultra-high performance concrete are fully played, the self-weight of an I-shaped beam is reduced,the construction efficiency is improved, the construction safety risk is greatly reduced, the whole machining process method is simple and reliable, procedures are few and simple, and the whole bridgeconstruction time can be greatly shortened; for the I-shaped beam subjected to high-temperature steam curing treatment, shrinkage creep of the I-shaped beam can be rapidly and completely completed inthe steam curing period, compared with a traditional concrete I-shaped beam, the inverted arch is small and easy to control, the economy of the whole life cycle is more remarkable, and the ultra-highperformance concrete I-shaped beam is suitable for bridges with the span smaller than 35 m.
本发明涉及超高性能混凝土工字梁加工方法，包括模板及预应力管道安装、混凝土浇筑及预埋剪力筋安装、喷洒养护剂及覆盖保湿膜养护、拆模、高温蒸汽养护等步骤，充分发挥超高性能混凝土超高的强度、超高的耐久性的优点，促使工字梁自重减少，提高施工效率且大大降低施工安全风险，整个加工工艺方法简单、可靠，工序少而简易，能够大大缩短整体桥梁建造的时间，通过高温蒸汽养护处理的工字梁，能够使得工字梁的收缩徐变在蒸养期内迅速完成全部收缩，与传统混凝土工字梁相比，反拱小且易控制，全寿命周期经济性更为显著，适用于跨径在35m以下的桥梁。
