Description

Technical Field

[0001] The utility model relates to the technical field of monopile foundations, in particular to a monopile foundation for a power transmission line. Background Art

[0002] In the construction of high-voltage power lines, monopile foundations are required. Monopile foundations can support the installation of transmission lines. During the installation and use process, it is necessary to ensure the high stability of the monopile foundation to avoid tipping.

[0003] The existing single pile foundation is generally composed of steel pipe piles and steel bars. The steel bars are installed inside the steel pipe column, and concrete is poured inside the steel pipe pile. After the concrete solidifies, a single pile foundation is formed. The single pile foundation is then inserted into the land through external equipment for use.

[0004] However, in actual use of the existing single pile foundation, the overall shape of the single pile foundation is in a vertical state. After installation, the part of the single pile foundation exposed to the ground is supported only by the outer wall of the steel pipe pile and the ground, so that the contact area between the steel pipe pile and the ground is small. During long-term use, the overall supporting strength of the single pile foundation is reduced, and it is easy to tilt outward, thereby reducing the overall strength of the single pile foundation. In view of the shortcomings of the existing technology, we propose a single pile foundation for transmission lines to solve the above problems. Utility Model Content
