The invention belongs to the technical field of subway ventilation pavilion vertical shaft construction, and particularly relates to a vertical shaft integral lifting formwork and a second lining construction method. In the integral formwork, the outer contour is a secondary lining formwork, a partition wall formwork is arranged in the integral formwork, the porous vertical shaft integral lifting formwork is vertically lifted through lifting equipment arranged on the ground, and the formwork is used for synchronous pouring of a secondary lining and a partition wall in a sectional mode. And after pouring is completed, the whole formwork is lifted to a certain height, pouring is repeated, and finally construction of the second lining and the partition wall in the whole vertical shaft is completed. According to the mode, more than half of the construction period can be saved, and the leasing cost of the equipment is greatly reduced. Compared with a rollover system in the prior art, the steel consumption is greatly reduced, the vertical shaft structure constructed through the structure does not need to be pre-buried, and later repair is reduced.

本发明属于地铁风亭竖井施工技术领域，特别涉及一种竖井整体提升模架及二衬施工方法。该整体模架中，外部轮廓为二衬模架，内部设置有隔墙模架，多孔竖井整体提升模架通过设置于地面的吊装设备进行竖直的提升，该模架用于分段式的进行二衬和隔墙的同步浇筑。浇筑完成后，整体将模架进行提升一定的高度，重复进行浇筑，最终完成整个竖井内二衬和隔墙的施工。该种方式能够节约大半的工期，也极大的解决了设备的租赁费用。与现有技术的翻模系统相比，用钢量极大的缩减，该结构施工的竖井结构无需预埋，减少了后期的修补。
