Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 to 4, the present embodiment provides a post tip structure including a pipe body 1, a post tip 2 and a ferrule 3.

The pile tip 2 comprises a first bending part 21 and a second bending part 22 which are fixedly connected and form an included angle with each other, the length of the first bending part 21 is smaller than that of the second bending part 22, the pile tips 2 are multiple and distributed along the circumferential direction of the pipe body 1, the pile tips 2 are hinged with the lower end of the pipe body 1, and the hinged points are not located at two ends of the pile tips 2; the ferrule 3 is sleeved outside the pipe body 1, and when the ferrule 3 is pressed down, the lower end of the ferrule 3 can be in contact with the first bending part 21, and the pile tips 2 can be rotated to a closed state.

In this embodiment, before piling, the pipe body 1 is lifted by an external device to separate the pile tip structure from the ground, and the first bent portion 21 is pressed down by the self weight of the ferrule 3 to rotate the plurality of pile tips 2 to the closed state. When piling, the closed pile tip 2 is inserted into the ground to pile, and the hoop 3 stays on the ground. This structure utilizes the dead weight of cuff 3 can carry out pile work again after a plurality of pile tips 2 are closed, does not need constructor manually operation pile tip 2, has easy operation, the security is high, characteristics that the efficiency of construction is high.
