Oblique prestress bridge deck pavement structure and construction method thereof
The invention relates to the field of highway bridge construction, in particular to an oblique prestress bridge deck pavement structure and a construction method thereof. The oblique prestress bridgedeck pavement structure comprises concrete; multiple prestressed tendons which are horizontally laid and obliquely arranged with the length direction of the bridge deck as the reference to form an oblique prestressed tendon pavement layer, wherein steel strands with the diameter being 15.2 mm are adopted as the prestressed tendons; constructional steel bars which are transversely arranged in the oblique prestressed reinforcement pavement layer in the height direction, and parallel to the long edge of the oblique prestressed reinforcement pavement layer; and stirrups which are used for fixing the constructional steel bars and are perpendicular to the constructional steel bars. By the adoption of the oblique prestress bridge deck pavement structure and the construction method thereof, the problems that in the prior art, a reinforced concrete pavement layer is prone to cracking, and unreliable performance of a reinforced concrete bridge deck structure is prone to being caused are solved.
本发明涉及公路桥梁施工领域，具体涉及一种斜向预应力桥面铺装结构及其施工方法，所述结构包括：混凝土；预应力筋，若干所述预应力筋水平铺设，以桥面长度方向为基准，倾斜设置，形成斜向预应力筋铺装层，所述预应力筋采用直径为15.2mm的钢绞线；构造钢筋，沿高度方向，所述构造钢筋横向设置于斜向预应力筋铺装层内，且所述构造钢筋平行于所述斜向预应力筋铺装层的长边；箍筋，所述箍筋用于固定所述构造钢筋，且与所述构造钢筋相垂直。采用本发明的斜向预应力桥面铺装结构及其施工方法，解决了现有技术中钢筋混凝土铺装层易开裂，容易造成钢筋混凝土桥面结构性能不可靠的问题。
