[0022] In actual use, during transportation, the lifting plate 2 is installed on the top of the inner wall of the concrete pipe pile 1 through a limiting mechanism, and a column 3 is fixed to the bottom end of the lifting plate 2. Several groups of reinforcing rods 4 are fixed on the rod body of the column 3. The reinforcing rods 4 are against the inner wall of the concrete pipe pile 1 to provide support for the core of the concrete pipe pile 1, preventing the concrete pipe pile 1 from undergoing excessive deformation under squeezing and bumping, thereby realizing the function of reinforcing the core of the concrete pipe pile 1; when the concrete pipe pile 1 is transported to the construction site, the lifting plate 2, column 3, and reinforcing rod 4 can be taken out of the concrete pipe pile 1 for recycling by releasing the limit of the limiting mechanism.

[0023] Example 2: On the basis of Example 1, in order to realize the operation of the limit mechanism, the limit mechanism includes: a limit groove 5, a limit rod mounting groove 6 and a limit rod 7. The limit groove 5 is opened on the inner wall of the concrete pipe pile 1, and the limit rod mounting groove 6 is opened on the surface of the hanging plate 2. One end of the limit rod 7 is movably inserted in the limit rod mounting groove 6, and the other end of the limit rod 7 is movably inserted in the limit groove 5. The limit rod 7 extends into one end of the limit rod mounting groove 6 and a limit spring 8 is fixed between the inner wall of the limit rod mounting groove 6. The surface of the hanging plate 2 is opened. There is a rope hole 9, in which a pull rope 10 is movably inserted. One end of the pull rope 10 extends into the limit rod mounting groove 6 and is fixed on the surface of the limit rod 7. The end of the pull rope 10 away from the limit rod 7 extends from the rope hole 9 and is fixed with a pull rod 11. The other end of the pull rod 11 is fixed with a connecting rod 12. A connecting groove 15 is provided at the top of the lifting plate 2. The connecting rod 12 is movably inserted into the connecting groove 15.

At this time, through the cooperation of the card slot 13 and the snap ring 14, the plug-in rod 12 is limited in the plug-in groove 15 to prevent the pull rope 10 from being accidentally pulled; when the limit needs to be released, the plug-in rod 12 is pulled out of the plug-in groove 15 with force, and then the pull rod 11 is pinched to pull the pull rope 10 out of the rope hole 9. The pull rope 10 drives the limit rod 7 to withdraw from the limit groove 5, so that the limit is released.

Several groups of reinforcing rods 4 are fixed on the rod body of the column 3. The reinforcing rods 4 are against the inner wall of the concrete pipe pile 1 to provide support for the core of the concrete pipe pile 1, preventing the concrete pipe pile 1 from being excessively deformed under squeezing and bumping, thereby realizing the function of reinforcing the core of the concrete pipe pile 1; when the concrete pipe pile 1 is transported to the construction site, the lifting plate 2, column 3, and reinforcing rod 4 can be taken out of the concrete pipe pile 1 for recycling by releasing the limit of the limiting mechanism; during transportation Under the elastic force of the limit spring 8, the push of the limit spring 8 on the limit rod 7 keeps the limit rod 7 in a state where one end is inserted into the limit groove 5 and the other end stays in the limit rod mounting groove 6, so that the limit mechanism plays the role of limiting the hanging plate 2 in the concrete pipe pile 1. At this time, through the cooperation of the card slot 13 and the snap ring 14, the plug-in rod 12 is limited in the plug-in groove 15 to prevent the pull rope 10 from being accidentally pulled; when the limit needs to be released, the plug-in rod 12 is pulled out of the plug-in groove 15 with force, and then the pull rod 11 is pinched to pull the pull rope 10 out of the rope hole 9. The pull rope 10 drives the limit rod 7 to withdraw from the limit groove 5, thereby releasing the limit.
