Research on Construction Technology of Complex Water-adjacent and Rock-socketed End Bearing Pile Foundation
The foundation of No.10 and No.11 main piers of Pingxin extra-large bridge on Jianhe-Liping Expressway in Guizhou Province is in a complex water-adjacent environment.The geology is silty slate rock,and the rock-socketed end bearing piles are designed.If the traditional hand digging pile construction is adopted,the risk is large and the period is long,which is difficult to meet the construction needs.Because the terrain is slope and adjacent to water,it is impossible to conduct normal vertical drilling construction.Based on the research,combined with the actual geological and hydrological environment,the drill platform is set up to create a construction environment for the impact drill,and the construction problem of rock-socketed end bearing pile in complex water-adjacent environment is solved.
