Description

Technical Field

[0001] The utility model relates to the technical field of assembled foundations, in particular to an anti-pullout anchor pile foundation. Background Art

[0002] The foundation is an important component of the transmission line. Ensuring its construction safety, reducing construction costs, shortening construction period and increasing its economy are the inevitable trends in the development of transmission lines. Considering many factors such as economy, safety, environmental protection and water conservation, and construction period, it is of great significance to select the appropriate foundation type under different conditions.

[0003] The spiral anchor foundation is a widely used foundation type and has been widely used in the cable-stayed foundation of overseas projects.
