Application of Pile End Pressure Grouting in Foundations Piles Reinforcement

In the reinforcement of big diameter pouring pile foundation piles,single pile bearing capacity cannot meet the design requirements because of bad pile end bearing stratum mechanics performance and thick pile bottom slag which can be reinforced by the use of pile end pressure grouting.The paper describes the conditions of realizing reasonable pile end grouting;pile end grouting can improve mechanics of single pile bearing capacity and impact analysis of grouting reinforcement.
