| Abstract: | In the construction of drilled cast-in-place pile foundation under the coal silo of Huanghua Coal Terminal Phase-3 project, post-grouting technology is adopted to renovate the quality defects existed in the construction of large-diameter drilled cast-in-place piles, such as settled material at the bottom of pile and thicker mud coat at the side of pile, which can increase the bearing capacity of pile foundation to a large extent. Now the principle of work, construction key points detail for post-grouting method strengthening for similar projects. and the measures to deal with common problems are introduced in the bearing capacity of pile foundation, which will provide references |
