[0001] The present application relates to the field of pipe piles, and in particular to a prestressed pipe pile structure. Background Art

[0002] At present, there are two main types of concrete prestressed pipe piles, namely pre-tensioned prestressed pipe piles and post-tensioned prestressed pipe piles. Among them, pre-tensioned prestressed pipe piles are made by pre-tensioned prestressing technology and centrifugal forming method, and the main structure is a slender hollow cylinder. Pre-tensioned prestressed pipe piles are mostly used in high-rise buildings and multi-story basement buildings, with the advantages of fast construction, short construction period and low cost.

[0003] The structure of the product can refer to a prestressed pipe pile structure disclosed in Chinese Patent Document No. 202120776191.6, which belongs to the field of pipe pile design technology, and includes: a pile body; and a center hole that runs through both ends of the pile body, and the insertion end of the pile body is movably connected with a breaking head, and the breaking head includes: a fixed block arranged on one side of the insertion end of the pile body, wherein the shape of the end of the fixed block away from the pile body is conical, and a disassembly and assembly mechanism is provided on the fixed block. The present application provides a prestressed pipe pile structure, which can assemble a fixed block with a conical bottom end on the pipe pile, so that the pipe pile can break the soil and rocks deposited in the pile hole when the pile is driven into the pile, so that the pile driving depth reaches a predetermined level.
