Application of Percussion Drill and Rotary Drill in the Construction of Dock Rock-socketed Oblique Piles

Weidong Peng

Abstract

The construction technology of perfusion type rock-embedded vertical pile has been relatively mature.However,using percussion drill and rotary drill for the construction of oblique rock-socketed pile both have successful examples in China.From a different perspective on construction equipments,this paper introduces the construction technology of oblique rock-socketed piles,analyzes and compares their adaptability,and finally puts forward the suggestion for choosing drills in oblique rock-socketed pile construction according to the results of analysis and comparison.
