Abstract:Taking the construction of steel trestle in Shiqian River in Guizhou as an example, the construction technology of post-planting anchor pile to reinforce the steel-pipe columns of the trestle is introduced. This technology is used to anchor the bottom of the steel-pipe pile of the trestle in the shallow buried riverbed. The effect of improving the anti-overturning stability of the trestle is obvious, which has the promotion and application value in similar engineering constructions.
