Steel bridge deck pavement structure and construction method thereof
The invention discloses a steel bridge deck pavement structure and a construction method thereof. The method comprises the following steps that S1, at least two steel bridge deck slabs are prepared; s2, sequentially carrying out the following construction procedures on each steel bridge deck slab: (1) carrying out sand blasting derusting treatment on the surface of the steel bridge deck slab, and welding shear nails; (2) laying transverse reinforcing steel bars and longitudinal reinforcing steel bars to form a mutually staggered grid structure layer; s3, reinforcing steel bars and tooth opening type end molds are arranged at the joints of the at least two steel bridge deck slabs; s4, the at least two steel bridge deck slabs are poured to form an ultra-high-performance concrete pavement layer; and S5, a wearing layer is laid on the ultra-high performance concrete pavement layer. According to the invention, the compressive strength, the shear strength and the fatigue resistance of the ultra-high performance concrete pavement layer can be improved, and the ultra-high performance concrete pavement layer is ensured not to flow and be subjected to stress distribution in the pouring process, so that the thickness of the ultra-high performance concrete pavement layer is ensured.
本发明公开了一种钢桥面铺装结构及其施工方法。该方法包括以下步骤：S1：准备至少两片钢桥面板；S2：对上述每片钢桥面板依序进行以下施工工序：(1)将钢桥面板表面进行喷砂除锈处理并焊接剪力钉；(2)铺设横向钢筋和纵向钢筋，形成相互交错的网格结构层；S3：在所述至少两片钢桥面板的接缝处设置补强钢筋和齿口型端模；S4：分别浇筑所述至少两片钢桥面板形成超高性能混凝土铺装层；S5：在所述超高性能混凝土铺装层上铺设磨耗层。本发明能够提高超高性能混凝土铺装层的抗压和抗剪强度、抗疲劳性能并且保证超高性能混凝土铺装层在浇筑过程中不发生流淌及受理分布以确保超高性能混凝土铺装层的厚度。
