The template is a steel template.
The installation and use process is as follows: according to design requirements, the specifications and the number of the feed-through jacks 5, the support rods 6, the radiation truss girders 3 and the lifting frames 4 are determined through the construction load calculation result.
The material is hoisted on the main platform through the equipment hoist, workers are lifted up and down through the personnel hoist and the safety cage, the system is assembled by using the material, the sliding formwork assembly of a plurality of inner chamber bodies 20 (gate piers/columns/walls) in a shaft is firstly carried out (the sliding formwork assembly controls the position and the angle through a total station in the assembling process, the precision of the sliding formwork assembly is ensured), then the truss girder 3 is radiated to the periphery to the well wall outer chamber body 2, each assembly directly passes through the enclosure, the isolated template system is connected into a whole through the radiation truss girder 3, the penetrating jack 5 is fixed by using the lifting frame 4, and the penetrating jack 5 passes through the support rod 6. And finally, the whole assembly system acts on the through jack 5 through a hydraulic system to synchronously slide and pour concrete along the support rod 6 from bottom to top, so that the one-step forming of the structure of the vertical shaft 1 is realized.
Because the concrete storehouse body is big, concrete is put in storage and adopts two kinds of modes, and the upper reaches side adopts hopper 14+ buffering elephant trunk 15+ annular radiation chute 18 to put in storage, and the downstream side passes through concrete trailer pump + pump line + hopper 14+ buffering elephant trunk 15+ multistage annular radiation chute 18 to put in storage. The concrete warehousing system of the buffer chute 15+ the multistage annular radiation chute 18 effectively prevents concrete segregation, realizes quick and uniform distribution and ensures the quality of concrete lining.
After the warehousing concrete meets the requirement of lifting the formwork, high-pressure oil is delivered to each through-type jack 5 through an oil pipe 13 through a hydraulic control platform 12, a piston of each through-type jack 5 is continuously compressed and reset in the continuous oil supply and return process, and the whole sliding formwork connected with the lifting frame 4 is driven to slide upwards by climbing on the supporting rod 6 through the through-type jacks 5.
And after the sliding mode is assembled, checked and debugged, entering an initial sliding stage. When the height is raised to 2m, the auxiliary disc 9 starts to be erected to serve as a concrete repairing and maintaining platform.

And the stability and operability of the whole die body and the sliding capacity of the feed-through jack 5 are checked during initial sliding, so that the relation between the concrete setting time and the pouring time, the control of the sliding height every time and the like are ensured. And (3) entering a normal sliding stage after initial sliding, distributing materials in layers, vibrating and sliding in layers according to shifts, wherein the time interval between two sliding times is generally controlled to be about 2 hours, and judgment and adjustment are carried out according to the concrete demolding strength or concrete penetration resistance value measurement and construction experience. The height of each pouring layer can be controlled to be 20cm, and the height of each lifting stroke is preferably controlled to be 5-8cm due to the fact that the air temperature in the vertical shaft 1 is constant and the mold body is large. All materials including steel bars, embedded parts and the like are hoisted to the operation platform from the bottom by the hoisting machine through the hoisting hole 11 until the sliding lifting is finished.
