Bridge deck slab construction sequence
The bridge deck slab construction sequence comprises the steps that supporting supports are arranged in spans on the two sides of a main tower, and a steel-concrete combined section of a main beam is placed on the supporting supports; the main beam steel-concrete combined section is poured, and when the strength and age of concrete in the cast-in-place main beam steel-concrete combined section reach preset values, the cast-in-place concrete section is tensioned; main beam side span cast-in-place sections are arranged on the supporting brackets on the two sides, and the cast-in-place concrete sections are tensioned; side span construction is completed; stay cables corresponding to all sections of the side span and the middle span are installed; cast-in-place is conducted on the steel-concrete combined section bridge deck slab, and when concrete in the steel-concrete combined section bridge deck slab reaches a preset value, stay cables corresponding to all the sections of the side span and the middle span are tensioned; a first section of the steel beam section is installed, a stay cable corresponding to the first section is installed, and the stay cable is tensioned; according to the construction method of the bridge deck slab, the line shape of the bridge can be reasonably controlled, the shear resistance of the wet joint of the bridge deck slab is improved, and cracking is prevented.
本发明公开了一种桥面板施工顺序，包括在主塔两侧跨内设置支撑支架，将主梁钢混结合段放置在支撑支架上；对主梁钢混结合段进行浇筑，当现浇主梁钢混结合段中混凝土强度和龄期达到预设值时，对现浇混凝土节段进行张拉；在两侧支撑支架上布置主梁边跨现浇段，并对现浇混凝土节段进行张拉；完成边跨施工；安装边跨和中跨各段对应的斜拉索；现浇钢混结合段桥面板，待钢混结合段桥面板中混凝土达到预设值时，对边跨和中跨各段对应的斜拉索进行张拉；安装钢梁段的第一节段，并安装第一节段对应的斜拉索，对斜拉索进行张拉；重复此步骤，直至主梁合龙，完成桥面板的施工，本发明能够合理控制桥梁的线形，提升桥面板湿接缝抗剪性能，防止开裂。
