Device for forming inserted and buckled type V-shaped piles

The invention discloses a device for forming inserted and buckled type V-shaped piles. The device comprises a concave V-shaped head pile machine and a square pile machine. A plurality of concrete square piles are manufactured, when the concrete strength of the square piles reaches a certain level, a concrete concave V-shaped head pile is manufactured by the concave V-shaped head pile machine at each of the left rear and the right rear of each square pile according to the working mode of the concave V-shaped head pile machine, concave V shapes of the concrete concave V-shaped head piles at the left rear and the right rear of each concrete square pile are matched with convex V shapes at the left rear and the right rear of the concrete square pile, and therefore the multiple concrete concave V-shaped head piles and the concrete square piles can be combined for forming the V-shaped piles for reinforcing weak foundations.
