Formwork reinforcing device based on foundation engineering

The utility model provides a formwork reinforcing device based on foundation engineering. The formwork reinforcing device comprises a reinforcing assembly, and the reinforcing assembly comprises a pushing rod, a clamping block, a threaded rod, a threaded cylinder, a rotating block, a supporting plate, a reinforcing rod, a rotating cylinder, a cylinder and a transmission rod; the formwork reinforcing device based on foundation engineering has the advantages that the threaded cylinder is rotated while the rotating rod is held by a hand, the threaded cylinder drives the two pushing rods to be close to each other, and therefore the threaded cylinder drives the clamping blocks to clamp and fix formworks on the two sides of the rotating block; and meanwhile, the formwork in front of the rotating rod is reinforced through the supporting plate, the device is easy to operate, the formwork can be reinforced by a single person, the trouble that multiple persons need to work cooperatively is avoided, meanwhile, the formw
