The alignment work of the anchor sleeve 62 and the connecting sleeve 71 can be assisted by drone technology.

[0065] Reference Figure 7 and Figure 8 By setting the anchor sleeve 62 into a metal sleeve 621 and an abutment sleeve 622, the metal sleeve 621 and the anchor bolt 61 have a higher connection strength; and the stiffness of the abutment sleeve 622 is smaller than the stiffness of the spike portion 73, so that the spike portion 73 can be inserted into the abutment sleeve 622, which is convenient for construction workers and improves the connection strength and stability between the anchor assembly 6 and the template 41.

[0066] The implementation principle of a tank inner wall leveling structure in the embodiment of the present application is: Reference Figures 6 to 8 When the first fixing component 51 applies a force to the second fixing component 52, the second fixing component 52 forces the formwork 41 to be in close contact with the concrete outer tank 1; at the same time, the plug-in rod 523 is inserted into the anchor sleeve 62, and the plug-in rod 523 forces the elastic rod 72 to expand outward, so that the spike portion 73 on the elastic rod 72 is engaged and fixed with the anchor sleeve 62; so as to improve the connection strength and connection stability between the anchor component 6 and the formwork 41.

[0067] Reference Figures 6 to 8When it comes to the demoulding stage, the fixed driving member unwinds, the second fixed assembly 52 loses the external force, and the spring member 524 forces the plug rod 523 to move away from the template 41, so that the plug rod 523 is separated from the anchor sleeve 62. When the plug rod 523 is separated from the anchor sleeve 62, the elastic mold forces the elastic rod 72 to move closer to each other, so that the spike portion 73 is separated from the abutment sleeve 622, so as to facilitate the separation of the mold and the concrete outer tank 1, facilitate the operation of the staff, and improve the leveling efficiency of the concrete outer tank 1.

[0068] Reference Figures 6 to 8 That is, through the connection between the anchor assembly 6 and the connecting assembly 7, the concrete outer tank 1 has a fixing effect on the template 41, so as to improve the stability of the connection between the concrete outer tank 1 and the template 41, facilitate the pouring of slurry into the recessed area 11, and improve the quality of the leveling member 10.

[0069] Embodiment 3:

[0070] The difference between this embodiment 3 and embodiment 1 is that: In this embodiment, in the vertical direction, the recessed areas 11 on the concrete outer tank 1 are arranged in a staggered manner.

[0071] Reference Fig. 9 At least two groups of traction components 3 are provided, and at least two groups of traction components 3 are provided on both sides of the recessed area 11 along the circumferential direction of the concrete outer tank 1. At least two groups of first fixing components 51 are provided, and the number of third positioning wheels 525 is the same as the number of first fixing components 51; along the circumferential direction of the concrete outer tank 1, at least two groups of second fixing components 52 are provided on both sides of the recessed area 11.

[0072] Reference Fig. 9 In this embodiment, two groups of traction components 3 are provided, and the two groups of traction components 3 are arranged on both sides of the recessed area 11 . Two groups of first fixing components 51 are provided, and the two groups of first fixing components 51 are arranged on both sides of the recessed area 11 .

[0073] The implementation principle of a tank inner wall leveling structure in the embodiment of the present application is: Reference Fig. 9 When a plurality of adjacent recessed areas 11 are provided on the concrete outer tank 1, two sets of traction components 3 are provided on the concrete ring direction, so that the staff can adjust the working conditions of the two sets of traction components 3 and move the template 41 to different recessed areas 11, thereby simplifying the leveling construction steps of the staff and improving the leveling efficiency of the concrete outer tank 1.

[0074] Reference Fig. 9, second fixing components 52 are arranged on both sides of the recessed area 11 along the direction of the concrete outer tank 1; so that when the recessed area 11 is not on the connecting line between the first positioning wheel 511 and the second positioning wheel 512, the horizontal forces exerted by the multiple groups of first fixing components 51 on the second fixing components 52 can offset each other, so that the multiple groups of first fixing components 51 jointly exert an action on the second fixing components 52 toward the concrete outer tank 1.

[0075] That is, by providing multiple groups of first fixing components 51 , the first fixing components 51 have a fixing effect on the templates 41 at different positions; thereby increasing the use range of the first fixing components 51 , simplifying the leveling steps, and improving the leveling efficiency of the concrete outer tank 1 .

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
