Title: Application of Pile Base Grouting Technique to Large Diameter and Long Bored Piles
Abstract: Donghai Bridge is in the real sense, the first bridge having ever been built over sea in China. In the trial piling for the bored piles of the navigable spans of the Bridge, the pile base grouting technique is used for the first time. At the time the casting of the concrete for the bored piles is completed, the cement mortar is then uniformly grouted to the pile bases through the pipes pre-embedded into the piles in order to increase the bearing capacity of the piles and reduce pile foundation settlement. The pile base grouting technique herewith undoubtedly provides a new idea for the construction of the large diameter and long bored piles with slurry wall protection in sea, and accumulates valuable experiences for more bridges to be built over sea in China in the future.
