Abstract：
The main loads of insert rock pile is resisted by the pile tip. The quality of inserting in rock is the key point that decides the quality of pile construction. In this paper, a method is introduced that can control the key points in construction , including the judgment of the pile into the rock , the thickness control of the bottom sediment. The inspection requirement of each key point in construction is proposed in this paper. As a result, the core drilling method plays an important role in the quality acceptance.
