Embodiment Construction
[0010] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0011] A high-stability prestressed pipe pile, comprising an outer pile 1 and an inner pile 2; the outer pile 1 is a hollow triangular prism structure; the inner pile 2 is a hollow cylinder structure; the inner wall of the outer pile 1 and the inner The outer wall of the pile 2 is tangent, and the solid part of the pile body is integrally formed. The wall thickness of the outer pile 1 is greater than the wall thickness of the inner pile 2 .
[0012] An embodiment of the present invention has been described in detail above, but the content is only a preferred embodiment of the present invention, and cannot be considered to limit the implementation scope of the present invention. All equivalent changes and improvements made according to the application scope of the invention should still fall within the scope of the invention.

The invention creatively provides a high-stability prestress pipe pile. The pipe pile comprises an outer pile body and an inner pile body; the outer pile body is of a hollow triangular prism body structure; the inner pile body is of a hollow cylindrical structure; the inner wall of the outer pile body is tangent with the outer wall of the inner pile body, and the pile body solid part is integrally molded; and the high-stability prestress pipe pile creatively has the beneficial effects that relative to an original cylindrical structure, the design of the hollow triangular prism body structure of the outer pile body is higher in single-pile foundation bearing, the bending resistance is greatly improved, and the phenomenon that due to insufficient pile body stability and strength, potential safety hazards are caused is avoided.
Description
technical field [0001] The invention relates to a high-stability prestressed pipe pile. Background technique [0002] At present, the prefabricated piles commonly used in the field of engineering technology include solid square piles, hollow square piles, and pipe piles. Although prestressed pipe piles are usually formed by centrifugal forming to improve the strength of the concrete of the pile body, due to the small size of the outer surface of the pipe piles, it may cause problems such as low bearing capacity and low bending resistance of single pile foundations, and there are potential safety hazards. SUMMARY OF THE INVENTION [0003] The problem to be solved by the invention is to provide a prestressed pipe pile with high stability. [0004] In order to solve the above-mentioned technical problems, the technical scheme adopted by the present invention is: a high-stability prestressed pipe pile, including an outer pile and an inner pile; the outer pile is a hollow tria...
