Mechanical punching Pile Foundation Construction in Karst Region is commonly used construction method. Faced with the complex geological conditions, Mechanical punching pile in the process of pile stuck drill frequendy occurred, How to analyze the cause, prevention stuck drill stuck drill phe- nomenon and timely processing stuck drill occurred after stuck drill accident, Become the construction progress and quality control of＂ the key. Combining with a project example, From analyzing the punching pile stuck driU cause of geological conditions, according to specific stuck drill, puts forward the prevention measures and stuck drill, the processing method of mechanieal punching pile construction for the site to offer reference and smoothly.
