Construction method for prestressed concrete bridge deck pavement
The invention relates to a prestressed concrete bridge deck pavement construction method, and belongs to the technical field of highway bridges. The construction method comprises the following steps that firstly, a prestressed concrete main beam is installed, and an anti-collision belt is made; 2, applying a prestressing load to the main beam; thirdly, tongue-and-groove joints/wet joints are made, and bridge deck pavement is conducted; fourthly, a tongue-and-groove joint/wet joint and bridge deck pavement concrete are cured; and fifthly, unloading is conducted, and prestress is formed. When the bridge deck pavement concrete is pre-stressed, the load applied to the main beam is scientifically and reasonably determined, the requirement for deformation of the bridge deck pavement concrete is met, and the pre-stress is sufficient in reserve but not redundant.
本发明涉及一种预应力混凝土桥面铺装的施工方法，属于公路桥梁技术领域。该施工方法包括以下步骤：第一步，安装预应力混凝土主梁，做防撞带；第二步，给主梁施加预应力化荷载；第三步，做企口缝/湿接缝和桥面铺装；第四步，企口缝/湿接缝和桥面铺装混凝土养护；第五步，卸载并形成预应力。本发明在进行桥面铺装混凝土预应力化时，科学合理地确定对主梁施加的荷载，既满足桥面铺装混凝土产生变形的需要，预应力储备充足，但不多余。
