The hydraulic pump station 7 outputs hydraulic kinetic energy to push the side pressure component 2 at the lower end of the beam 1 and the positive pressure component 3 on the side of the culvert trolley body 4 to operate simultaneously. The side pressure component 2 cooperates with the positive pressure component 3 to build casting templates of different specifications and sizes.
