The invention discloses a construction method for synchronous formwork supporting and concrete pouring of a bottom plate and a top plate of a cast-in-place pipe gallery, and relates to the technical field of concrete pouring. According to the method, the supporting strength of the concrete bottom plate is improved through a vertical supporting device, a formwork supporting system is erected on the bottom plate, the top plate and the side walls, meanwhile, concrete pouring and curing are carried out on the bottom plate, the top plate and the side walls, the formwork supporting system is disassembled after curing is completed, a vertical rod and a horizontal supporting rod on the upper surface of the bottom plate concrete are partially cut off, and simultaneous pouring operation is completed. According to the method, the vertical supporting device is easy to manufacture and convenient to install; the number of procedures is small, and the efficiency is high; the construction period of the supporting system is short, and the installation speed is high; the loss is small, and the construction cost is low; the supporting system does not need to be welded with bottom plate steel bars, and the application range is wide; the stress balance of the side walls is good, and the stability of the supporting frame is good; the supporting effect is good, and potential safety hazards are avoided; and the bottom plate, the top plate and the side walls are synchronously implemented, no construction joint exists, the integrity is good, the anti-seepage effect is good, and the construction period is greatly shortened.
本发明公开了一种现浇管廊底板和顶板同步支模浇筑混凝土的施工方法，涉及混凝土浇筑技术领域。本方法通过竖向支撑装置增加混凝土底板的支撑强度，对底板、顶板和侧壁搭设模板支撑体系，同时对底板、顶板和侧壁进行混凝土浇筑和养护，养护完成后拆除模板支撑体系，将底板混凝土上表面的立杆和水平支撑杆部分切除，完成同时浇筑作业。本方法中竖向支撑装置制作简单，安装方便；工序实施少，效率高；支撑体系施工周期短，安装速度快；损耗小，施工成本低；不需要与底板钢筋焊接，使用范围广；侧壁受力平衡性好，支撑架稳定性好；支撑效果好，无安全隐患；底板、顶板、侧壁同步实施，无施工缝，整体性好，防渗效果好，大大缩短工期。
