Research on Key Control Point of Bored Pile Construction Technology in Railway Bridge and Culvert Construction
Bored pile is a common foundation form in railway bridge and culvert engineering in China.It is a widely used technical measure with simple process,high construction efficiency and good adaptability.The bored pile foundation structure belongs to underground concealed engineering,which is affected by geology and geographical location,and the construction is difficult.Therefore,good construction technology control is an important link to ensure the quality of pile foundation.Based on the specific engineering case,this paper analyzes the technical control points of four core construction links in the construction of bored piles,namely,the production and embedding of protective tubes,hole drilling,the production and installation of reinforcement cages,and underwater concrete pouring,in order to provide reference for the control of bored pile construction technology and ensure the quality of technology implementation.
