Abstract: Post-grouting pile has been widely applied in the field of civil building, as a new type of pile foundation recommended in technical code for pile foundations. However, it could not be used in transmission line directly due to the lack of theoretical parameters and practical application. This paper investigated the post-grouting piles used in the field of transmission line, such as strengthening mechanism, design calculation, grouting layout, technological process, construction equipment, artificial material and so on. The calculation method was suggested for the post-grouting pile under uplifting load and horizontal load. And the main advantages, application scope and economy of post-grouting piles were analyzed and compared.
Key words: post-grouting, tower foundation, transmission line
