Through the extension and retraction of the second opening and closing cylinder 3073, the two opening and closing lower templates 3072 can be controlled to open and close, thereby achieving the above-mentioned foldable effect and avoiding the interference relationship with the inner lower template 305 when opening at the same time. The first opening and closing cylinder 309 is hingedly arranged on the middle lower template 3071.

[0054] It should be noted that the number and arrangement positions of the first opening and closing cylinders 309 and the second opening and closing cylinders 3073 provided on the inner lower terminal template 307 and the inner lower template 305 should consider reserving sufficient space to facilitate the movement of the partition wall assembly template assembly 4.

The two partition wall formwork support frames 402 can slide towards each other to realize the different heights of the partition walls 102. It should be noted that a space for sliding towards each other is reserved between the two partition wall formwork support frames 402. A plurality of height-adjusting cylinders 403 are arranged on the partition wall formwork support frames 402. The specific number of the height-adjusting cylinders 403 should meet the support requirements of the partition wall 102. A partition wall formwork 404 is arranged on the output end of the height-adjusting cylinder 403. The partition wall formwork 404 meets the shape of the partition wall 102. The top of the partition wall formwork 404 is open, which is convenient for pouring the partition wall 102 from the top thereof.

[0065] In the open type, the opening and closing upper template 6032 needs to be opened first. When closing, the inner upper template 602 and the inner upper end template 603 need to be closed first, and then the opening and closing upper template 6032 and the inner lower end template 307 are opened and closed in the same manner.

[0066] The present embodiment provides a formwork mechanism for prefabricating an assembled fishway unit 1 in a flat manner, which can effectively avoid the situation where the partition wall 102 formwork needs to be constructed above the bottom plate of the U-shaped unit 101 during vertical prefabrication, effectively ensuring the casting quality of the bottom plate of the U-shaped unit 101, while ensuring the supporting force required for the partition wall formwork. At the same time, by providing a formwork that can be opened at a small angle, demoulding is facilitated.
