Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4This utility model provides the following technical solution: a bridge pier mold for preventing grout leakage, including a first mold 1, a second mold 2 set on the top of the first mold 1, a first bolt 6 threadedly connected to both sides of the second mold 2, a second nut 7 set on the surface of the first bolt 6, a work box 8 set at both ends of the second mold 2, a motor 11 fixedly installed on one side of the work box 8, a first bidirectional threaded rod 13 set at the output end of the motor 11, a first sprocket 14 fixedly installed at one end of the first bidirectional threaded rod 13, a chain 4 meshing with the surface of the first sprocket 14, a second sprocket 16 meshing with the inner wall of the chain 4, a second bidirectional threaded rod 15 fixedly connected to one side of the second sprocket 16, a clamping plate 9 threadedly connected to both ends of the surfaces of the second bidirectional threaded rod 15 and the first bidirectional threaded rod 13, and a second bolt 12 threadedly connected to both sides of the first mold 1, a first nut 3 set on the surface of the second bolt 12.

[0016] In a specific embodiment of this utility model, two first molds 1 are placed together and fixedly connected using a second bolt 12 and a first nut 3. A motor 11 operates, causing the first bidirectional threaded rod 13 to drive the chain 4 on the surface of the first sprocket 14 to rotate, which in turn causes the second sprocket 16 to drive the second bidirectional threaded rod 15 to rotate. This causes the clamping plate 9 to move inside the work box 8, clamping the two second molds 2 together. The second molds 2 are then snapped onto the top of the first molds 1, and the first bolt 6 and the second nut 7 are used to secure the two second molds. 2. The first mold 1 is fixedly connected to the second mold 2. Cement slurry is poured into the interior of the first mold 1 and the second mold 2 for molding, effectively preventing cement slurry leakage. The motor 11 works to drive the first bidirectional threaded rod 13 to drive the chain 4 on the surface of the first sprocket 14 to rotate in the opposite direction, and the second sprocket 16 drives the second bidirectional threaded rod 15 to rotate. The clamping plate 9 is moved to both sides to disassemble. Then the first nut 3 and the second nut 7 are removed from the surface of the first bolt 6 and the second bolt 12.

The operator holds the handle 5 and places the work box 8 at both ends of the second mold 2. The motor 11 is activated, causing the first bidirectional threaded rod 13 to drive the chain 4 on the surface of the first sprocket 14 to rotate, which in turn drives the second sprocket 16 to drive the second bidirectional threaded rod 15 to rotate, causing the clamping plate 9 to move inside the work box 8, clamping the two second molds 2 together for assistance and reducing the need for multiple people to work together. Then, the second mold 2 is snapped onto the top of the first mold 1, and the two second molds 2 and the first mold 1 are fixedly connected using the first bolt 6 and the second nut 7. Cement slurry is then poured into the first... The molds 1 and 2 are formed inside each mold to effectively prevent cement slurry leakage. Motor 11 drives the first bidirectional threaded rod 13 to rotate the chain 4 on the surface of the first sprocket 14 in the opposite direction, causing the second sprocket 16 to rotate the second bidirectional threaded rod 15. The clamping plate 9 is then moved to both sides for disassembly. The first nut 3 and the second nut 7 are then removed from the surfaces of the first bolt 6 and the second bolt 12. The first mold 1 and the second mold 2 are then disassembled. The operation is simple, reducing the difficulty of operating this equipment.
