When the anti-floating anchor pile 100 receives a tensile force in the bottom-to-top direction of the pipe pile 1, the anti-floating anchor pile 100 applies a compressive force in the bottom-to-top direction of the pipe pile 1 to the movable member 3 in addition to a frictional force in the bottom-to-top direction of the pipe pile 1 generated between the anti-floating anchor pile 100 and the base body, and the frictional force and the compressive force together form an anti-pulling force of the anti-floating anchor pile 100. Compared with the prior art which mainly uses the friction force between the anti-floating anchor pile and the soil body as the pulling resistance, the pulling resistance of the anti-floating anchor pile 100 can be greatly improved.

When the pipe pile 1 reaches the preset depth of the matrix, the four lifting pieces 4 are pulled to enable the four movable pieces 3 to be in the unfolding state.

By arranging a plurality of movable pieces 3 and a plurality of lifting pieces 4, the radial dimension of the bottom end of the anti-floating anchor pile 100 is larger when the anti-floating anchor pile is in a unfolded state, and the anti-pulling force of the anti-floating anchor pile 100 is further improved; moreover, when in the unfolding state, the anti-floating anchor pile 100 is stressed uniformly in the circumferential direction of the pipe pile 1, so that the use reliability of the anti-floating anchor pile 100 is improved.

In the closed state, the first portion is fitted to the outer peripheral surface of the pipe pile 1, and the first portion forms a fitting portion 322.

In the closed state, the attaching portion 322 is attached to the pipe pile 1, so that the size of the anti-floating anchor pile 100 in the radial direction of the pipe pile 1 can be effectively reduced, and accordingly, when the anti-floating anchor pile 100 enters the pile hole in the closed state, the sinking resistance of the anti-floating anchor pile 100 can be effectively reduced, the anti-floating anchor pile 100 can be conveniently and rapidly lowered into the pile hole, and the installation efficiency of the anti-floating anchor pile 100 can be improved.

Specifically, if the preset angle between the movable member 3 and the tubular pile 1 is 40 ° in the unfolded state, when the movable member 3 swings to an angle of 40 ° with the tubular pile 1, the movable member 3 is well stopped against the stopper 9, so that the movable member 3 cannot continue to rotate, and the movable member 3 swings and is kept at 40 °. The reliability of the anti-floating anchor pile 100 is further improved.

Alternatively, the pull member 4 is a steel strand.

For example, the pull-up element 4 is a prestressed steel strand.

By setting the lifting piece 4 as a steel strand, the lifting piece 4 can bear larger pulling force, so that the anti-floating anchor pile 100 is effectively prevented from breaking due to larger stress in the use process.
