Application And Analysis Of Post Grouting Technology In A Project

In recent years,our country of pile foundation engineering to the way of rapid development.In order to adapt to different geological layers,the type of construction and construction technology,have sprung up more and more,the construction process more complicated At present,the bored piles in all kinds of buildings,transportation,ports and other industries in the most widely used It has low noise,high safety,strong adaptability and small impact on the surrounding buildings,etc.With the development of building diversified,piles to super depth,large diameter,large carrying capacity,the construction of difficulty is also gradually increase,at the same time,some engineering quality and safety problems also followed,direct or indirect economic loss.Therefore,in order to reduce the problem,reduce loss,need to go into details of construction technology of bored piles,optimization of construction details,avoid construction in similar quality problem in the future.Firstly,the pile quality defects in the hole process,matters needing attention in the construction,pile quality problems are introduced,the post grouting to solve the insufficient bearing capacity and pile bottom sediment analysis.Then using ANSYS software to comparative analysis of the stress value of grouting pile bottom grouting,it can improve the bearing capacity of pile foundation,and illustrates the post grouting technique to solve the sediment at the bottom of the pile and the bearing capacity problem.Finally,combined with the construction process of bored pile mud of Fujian Tianhui petrochemical logistics limited pile foundation project in practical engineering,the mechanism of post grouting construction technology,grouting process problems and countermeasures,and through the analysis of the parameters of grouting and the detection effect,not only explains the guarantee with the effectiveness and superiority of the force security but also to save the economy,provide guidance and advice on the construction of pile foundation of the same type in the future.
