Vertical shaft building construction method and device

The invention relates to a vertical shaft building construction method and device.The vertical shaft building construction method comprises the following steps that a to-be-excavated vertical shaft is divided into a central excavation area and a peripheral excavation area surrounding the outer side of the central excavation area; the peripheral excavation area is excavated, and the outer side structure and the inner side structure sink into the peripheral excavation area; the central excavation area is excavated, and an inner side structure is dismantled; in the excavation process of the peripheral excavation area, the height of the excavation face of the central excavation area is larger than or equal to that of the excavation face of the peripheral excavation area; the bottom of the well in the peripheral excavation area is sealed; and the bottom of the well in the central excavation area is sealed. In addition, the construction is matched with a novel tunneling device. The problems that in the prior art, a
