[0010] As a further solution of the utility model: a sealing anti-skid layer is provided on the outside of the assembly seat, and the sealing anti-skid layer is in close contact with the inner wall of the contraction extension section.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model can directly press the upper section of the lining onto the two pit liners after the pit lining is poured, and can directly carry out the closing operation of the upper section of the pit lining, and two contraction extension sections are assembled at the contraction position of the pit lining, and the setting of the contraction extension section can ensure the smooth passage of the subsequent hoisting bottom ring, and thus adopting this method can avoid waiting for the bottom ring to be processed before the closing operation, thereby speeding up the construction progress.

[0013] 2. The utility model provides a closed structure. After the bottom ring is hoisted, the assembly seat is embedded in the contraction extension section. Due to the trapezoidal fit between the two, the assembly seat can be prevented from continuing to fall, and the steel bar is passed through the second insertion opening and then out of the first insertion opening, so that the steel bar can again serve to fix the assembly seat and the contraction extension section. At the same time, the hollow design of the assembly seat can realize casting, so that after casting and forming, the steel bar can effectively play a role in reinforcing the assembly seat.

The contraction extension section 4 can play a role in expanding the port, ensuring smooth passage of the subsequent hoisting bottom ring, and thus adopting this method can avoid waiting for the bottom ring to be processed before closing the port, thereby speeding up the construction progress. At the same time, after this method is implemented, the delivery cycle of the bottom ring and water guide and rotating sleeve parts of the pumped storage unit can be extended by 3 months, reducing the production pressure in the factory, better balancing the production plan in the factory, reasonably allocating manpower and material resources, and adjusting the economy brought about by the adjustment of the supply period. The shrinkage extension section 4 is in the shape of a trapezoid, and three corresponding second insertion openings 6 are provided on both sides of the shrinkage extension section 4, and the second insertion openings 6 can ensure the passage of the steel bars, and the two pit liners 1 are butted against each other, and the lining upper section plate 7 is pressed on the upper part of the two pit liners 1, and the pit lining shrinkage opening 2 and the two shrinkage extension sections 4 are both assembled on the lining upper section plate 7, and the lining upper section plate 7 is pressed on the pit lining 1, which can play the role of closing, and the pit lining 1 can shape the concrete during the pouring process, and the two shrinkage extension sections 4 are assembled on both sides of the pit lining shrinkage opening 2, and the bottoms of the two shrinkage extension sections 4 are connected to the lining upper section plate 7, and the inner The part is also embedded with a closed structure 3, which includes an assembly seat 31. The shape of the assembly seat 31 is compatible with the shape of the contraction extension section 4, and the assembly seat 31 is hollow. The hollow design of the assembly seat 31 can facilitate the operation of injecting concrete, so that after pouring and forming, the position of the steel bars is fixed, so that the steel bars can effectively play the role of reinforcing the assembly seat 31. Fixed blocks 32 are fixedly connected to the upper sides of the assembly seat 31. Limiting openings 5 ​​are provided at the two edges of the top of the contraction extension section 4.
