Main Points on Construction Method of Bite Piles for Deep Foundation Pits in Mountainous Riverbeds:Taking the Deep Foundation Pit Support Project of National Highway 109 as an Example
Traditional construction methods such as diaphragm walls,underground continuous walls,sheet piles,and caissons have certain limitations and issues,which include reduced water resistance due to pile gaps,high cost and long construction period for underground continuous walls,and constraints on sheet piles and caissons due to geological conditions.In order to achieve effective water sealing performance in deep foundation pit support and expedite construction progress while saving costs,the bite pile construction technology has emerged.Taking the support of the deep foundation pit for the Fengsha Railway Rotating Bridge on the Anjiazhuang Super Bridge project of National Highway 109 as an example,a detailed introduction to the application and effectiveness of the bite pile support structure was provided.The bite pile construction technology was successfully applied in this project,achieving favorable results.It holds significant reference value for similar construction projects in the future.
