Ultra-deep vertical shaft sequential lining unilateral formwork lifting mold frame and construction method

The invention discloses an ultra-deep vertical shaft sequential lining unilateral formwork lifting mold frame. The mold frame comprises a pre-embedded supporting system, a lifting mold frame main beam, a supporting frame body, and a bottom walking platform. A construction method includes the steps that after the binding of first-layer steel bars is completed, a next-layer supporting embedded partis embedded, and the lifting mold frame is synchronously installed on a vertical shaft bottom plate; then a formwork is installed, and steel pipe supports and the lifting mold frame are connected to form a formwork reinforcing system; concrete is poured and cured, and a platform at the top of the lifting mold frame can be used for binding a next layer of the steel bars during curing; after maintenance is completed, the steel pipe support is detached, demolding is conducted, and the supporting system is installed; and finally, hoisting equipment is adopted for integrally hoisting and lifting the lifting mold frame to t
