[0026] When the concrete pipe pile 1 is subjected to anti-settlement work:

[0027] The concrete pipe pile 1 is inserted into the pile hole, and the bottom plate 2a6 fits with the bottom of the pile hole. The concrete pipe pile 1 continues to fall, and the bottom plate 2a6 drives the curved rod 2a5 to move upward, and the curved rod 2a5 drives the inclined rod 2a4 to move, and the inclined rod 2a4 drives the rod body 2a1 to move outward, so that the rod body 2a1 is inserted into the soil, thereby realizing a primary anti-settling work, and the circular plate 13 is fixedly connected to the external concrete pipe pile 1.
