Analysis on Anti-sloughing Mud Properties in the Pile Foundation Borehole Construction

Abstract:

Hole collapse and diameter shrinkage often occur in the pile foundation borehole construction, the borehole quality directly affects the quality of the bored grouting pile. Except for casing in borehole construction, the most effective wall protection method is by sloughing mud. Through the comparison and analysis on various mud with ingredients, the best formula of collapse preventing mud is selected to improve the stability of hole wall in bored grouting pile construction.
