Installation method of underground station rail top air duct prefabricated structure
The invention discloses an installation method of an underground station rail top air duct prefabricated structure. The installation method comprises the steps that firstly, rail top air duct prefabricated section blocks are split and numbered according to a design file, and a rail top air duct prefabricated component design file is formed; a prefabrication factory conducts prefabricated block formwork manufacturing and rebar blanking manufacturing according to the prefabricated component design file, and prefabricated component prefabrication is completed; then, station and interval construction plan arrangement is combined, a rail top air duct can be positioned and installed before station middle plate pouring and can also be installed through jacking equipment after middle plate pouring; and finally, adjacent prefabricated blocks are subjected to caulking treatment through polymer modified cement mortar. According to the installation method, rail top air duct installation is rapid and convenient, jacking in-place is conducted through tools such as a forklift, the construction efficiency is greatly improved, and precious time is won for subsequent professional construction of a station. The technical effect is obvious, and the installation method can be applied and popularized.
本发明公开了一种地下车站轨顶风道预制结构的安装方法，首先根据设计文件对轨顶风道预制节块进行拆分、编号，形成轨顶风道预制构件设计文件；预制厂根据所述预制构件设计文件进行预制块模板制作、钢筋下料制作，完成预制构件预制；再结合车站、区间施工计划安排，轨顶风道可以在车站中板浇筑前定位安装，也可以在中板浇筑后通过顶升设备进行安装；最后相邻预制块采用聚合物改性水泥砂浆做嵌缝处理。本发明的方法使得轨顶风道安装快捷、方便，通过叉车等工具进行顶升就位，大大提高了施工效率，为车站后续专业施工赢得了宝贵时间。技术效果明显，可推广应用。
