[0052] Based on the above structural setting, the working principle or use method of the prefabricated platform of the irregular arc wall structure of the present invention is as follows:

[0053] S1. Please refer to Figure 4 , the two bottom molds 401 are pushed by the first pushing mechanism 408 to make the two bottom molds 401 slide on the bottom plate 1 to control the distance between the two bottom molds 401 to match the thickness requirement of the arc wall structure to be cast;

[0054] S2. Please refer to Figure 4 , according to the designed curvature and shape of the arc-shaped wall structure to be cast, a bottom mold fixing hole 4021 in the bottom mold fixing hole group 402 is selected as the end starting point of the side mold 404, and the position of each positioning block 4033 is adjusted by the second pushing mechanism 4011, so that the positioning hole of each positioning block 4033 and the determined bottom mold fixing hole 4021 are on the same longitudinal axis, and the required moving distance of the positioning block 4033 in the positioning slide groove 4032 in each template positioning component 403 on the bottom mold 401 is calculated and determined, so that the bottom mold fixing hole 4021 and the positioning hole 4034 in each template positioning component 403 form corresponding control points that constrain the linear shape of the side mold 404;

[0055] S3. Please refer to Figure 5 , vertically place the side mold 404 on the bottom mold 401, and fine-tune its position to align the side mold through hole 4041 of the side mold 404 with the determined bottom mold fixing hole 4021, and align each side mold through groove 4042 of the side mold 404 with each positioning hole 4014 one by one, then insert the fixing rod 405 through the side mold through hole 4041 and the bottom mold fixing hole 4021, and insert the positioning rod 406 through the side mold through groove 4042 and the positioning hole 4014, thereby completing the preliminary positioning of the side mold 404;

[0056] S4. Please refer to Figure 6 and Figure 8 , according to the required moving distance of the positioning block 4033 calculated and determined in step S2, the second pushing mechanism 4011 synchronously and slowly pushes each positioning block 4033, so that the positioning block 4033 in each template positioning assembly 403 slides to the designed position in the positioning slot 4032, and the positioning block 4033 drives the side mold 404 to move through the positioning rod 406 to achieve bending deformation of the side mold 404. At this time, the arc connecting the control points formed by the bottom mold fixing hole 4021 and the positioning holes in each template positioning assembly 403 is the wall side shape of the linear or arc-shaped wall structure after the side mold 404 is installed and positioned;

[0057] S5. Please refer to Figure 7 and Fig. 9 , fill the positioning groove 4032 between the side molds with paraffin wax to prevent the concrete from blocking the positioning groove 4032 during subsequent concrete pouring, and then install the end mold 407 and the template reinforcement assembly 5 to connect and reinforce the side mold 404 bent into the required arc structure;

[0058] S6. After applying a release agent on the side of the side form 404, the bottom form 401 and the end form 407 that are in contact with the concrete, concrete construction is carried out. After the concrete reaches the ideal strength, the formwork is removed. When removing the formwork, the formwork reinforcement component 5 is first removed, and then the second jacking mechanism 4011 is slowly retracted. The formwork is controlled to slowly restore its original linear shape through the coordinated retraction of each second jacking mechanism 4011. Finally, the installed fixing rod and positioning rod are pulled out, and then the side form 404 and the end form 407 are removed, and the wall structure is hoisted and stored.

[0059] Further, in a specific embodiment, see Figure 1 , Figure 7 and Fig. 9 The template reinforcement assembly 5 includes a plurality of side support members 501 supported between the side form 404 and the side support plate 2 on the same side, a horizontal connecting rod 502 connected between the top ends of the fixing rods 405 of the two side forms 404 or between the top ends of the positioning rods 406, and a side support rod 503 connected to the top end of the fixing rod 405 or the positioning rod 406 at one end and to the bottom plate 1 at the other end; preferably, the side support member 501 is a scissor jack, and the top support surface of the scissor jack is provided with an arc-shaped rubber block 5011 as a support portion for the outer side of the side form 404; based on the above structural arrangement, the side support member 50 1 and the side support rod 503 can provide lateral support for the template to ensure that the overall strength of the template structure meets the requirements when pouring concrete; the cross connecting rod 502 can connect the two side templates 404 to form an integral structure; the use of scissor jacks as side support members 501 can facilitate construction and improve efficiency; when installing the template reinforcement component 5, the scissor jacks, side support rods and cross connecting rods should be installed starting from the side with the largest relative lateral displacement of the side template 404, that is, the template reinforcement should be performed on the side with the largest bending deformation first; and when removing the template, the scissor jacks should be retracted in coordination first, and then the side support rods and cross connecting rods should be removed.

[0060] In order to make the bottom mold 401 slide more smoothly horizontally on the bottom plate 1 and prevent the bottom mold 401 from longitudinally deviating, further, in a preferred embodiment, refer to Figure 1 and Figure 5 Guide grooves 101 are arranged on both sides of the bottom plate 1, and guide wheels 4011 which can be embedded in the guide grooves 101 and roll are arranged on both sides of the two bottom molds 401; preferably, the guide wheels 4011 are steel wheels.

Similarly, a conventional arc with a smoother curvature can also be formed through the 5 constraint points.

[0062] Further, in a preferred embodiment, see Figure 6 and Fig.10 The bottom mold fixing hole group 402 includes 3-5 bottom mold fixing holes 4021; by setting a plurality of bottom mold fixing holes 4021, the bottom mold fixing holes 4021 at different positions can be selected to cooperate with the positioning holes 4034 to achieve more flexible curvature and shape adjustment of the side mold 404.
