Analysis On Applying Post-grouting Technique In Bored Pile

Bored pile post grouting is a bored pile method. The technology designed by thesolidified concrete pile pile side grouting pile, So that the sediment, soil and mud are cured,And through the slurry pressure penetration of pile and pile in a certain range of soilreinforcement treatment of pile foundation engineering quality, increase reliability, Improvepile bearing environment the pile foundation, Tthe actual bearing capacity is greatly enhanced,And to reduce the settlement of pile foundation.This paper analyzes the post grouting bored pile mechanism, Process characteristics andbearing capacity characteristics, Summed up the impact of post grouting bored pile bearingcapacity of the main factors and the effect of these factors, And the relationship between eachother. On the grouting pile bearing capacity calculation, Settlement calculation methods areanalysed.Combined with a giant silo structure in pile foundation design case, According to thespecific geological conditions, The pile foundation design and post grouting bored pileoptimization problems are analyzed; in large loads, Considering the soil plastic flow and thepile-soil interaction, Using FEM ADINA software for pile foundation in soft soil foundationwork traits are analyzed in detail; And with the pile foundation for the Mindlin method thecalculated results were compared with test. Results show that the post grouting bored pile insoft soil foundation in, In large loads can effectively play its excellent bearing properties;Combined with a certain high-rise building pile foundation settlement calculation for pilefoundation of the project case, The uneven loads subsidence equivalent summation methodfor simulation and calculation of post grouting bored pile, Significantly improve the pilefoundation settlement, Different load location between settlement has been effectivelycontrolled..
