Cast-in-place concrete pile by using deep well injection method was originated in the U.S. The injection method was used for the treatment of wasted materials from the petroleum generation process by injecting the waste material into the deep rock fissures through the deep wells. Currently, this injection method has been widely used in the deep and large diameter castinplace reinforced concrete pile installations. This paper presents a case history of the technique and quality control aspects of constructing of the large diameter castinplace reinforced concrete piles.

Key words: Cast-In-Place Reinforce Concrete Piles with Enlarged Base, Piling Engineering, Quality Control, Construction Technique
