In all types of pile, bored pile applied universally, bored piles due to various geological conditions adaptability, simple construction and easy operation and low equipment investment is not very big, have been widely used in various types of housing and construction. So in order to speed up the construction progress, ensure the quality, save the cost, in terms of its construction technology and quality control is of great significance to do. This paper mainly from the aspects of construction technology and quality control of bored pile on the simple discussion and analysis.
