Large-span assembled continuous pile plate structure adopting UHPC (Ultra High Performance Concrete) assembly plates and assembly construction method
The invention relates to the technical field of bridge engineering, in particular to a large-span assembly continuous pile plate structure adopting UHPC assembly plates and an assembly construction method. A large-span assembly continuous pile-plate structure of a UHPC assembly plate is adopted, and the middle prefabricated pipe pile is located between the two end prefabricated pipe piles; precast concrete main body bridge deck slabs are respectively erected between the two end precast pipe piles and the middle precast pipe piles; u-shaped crossed steel bars are arranged at the tops of the middle prefabricated pipe piles, and U-shaped longitudinal connecting steel bars are arranged at the ends, opposite to the prefabricated concrete main bridge deck slab, of the prefabricated UHPC assembly plates correspondingly; the U-shaped longitudinal connecting steel bars are arranged in a staggered manner and are inserted with transverse steel bars; the prefabricated pipe piles located in the middle and the prefabricated concrete body bridge deck slab are connected in a pouring mode through the prefabricated UHPC assembly plates to form a continuous pile-slab structure. According to the large-span assembly continuous pile plate structure adopting the UHPC assembly plates and the construction method, the overall rigidity and the spanning capacity of the assembly pile plate structure are improved, the bad aesthetic effect caused by small-span dense pile plates is improved, and the large-span assembly continuous pile plate structure has the advantages of being convenient to construct, environmentally friendly, economical and high in economical efficiency of the assembly pile plate structure.
本发明涉及桥梁工程技术领域，尤其涉及采用UHPC装配板的大跨径装配连续桩板结构及装配施工方法。采用UHPC装配板的大跨径装配连续桩板结构，中部预制管桩位于两根端部预制管桩之间；两根所述的端部预制管桩与中部预制管桩之间分别架设预制混凝土主体桥面板；中部预制管桩顶部设有U形交叉钢筋，预制UHPC装配板（与预制混凝土主体桥面板相对端分别设有U形纵向连接钢筋；U形纵向连接钢筋交错布置且穿插有横向钢筋；位于中部预制管桩、预制混凝土主体桥面板通过预制UHPC装配板浇筑衔接形成连续桩板结构。本发明提供的采用UHPC装配板的大跨径装配连续桩板结构和施工方法，提高了装配化桩板结构整体刚度及跨越能力，改善了小跨径密集桩板带来的不良美学效果，兼具装配化桩板结构施工便捷、环保节约、经济性强的优势。
