Application of PHC and CFG composite piles in the Zhengzhou Aviation Port area

Abstract:

The characteristics and applicable conditions of PHC pipe piles and CFG piles are discussed. Based on the engineering geological conditions at the construction site of the Escort Center of the Zhengzhou Aviation Port Economic Comprehensive Experimental Zone, analysis is made of the problems with separate use of PHC pipe piles, the CFG pile composite foundation and bored cast-in-place piles. In regard to the geological condition and the load condition of the building, the feasibility and rationality of selecting the combination of the PHC pipe pile and the CFG pile are discussed. This paper introduces the construction technology and optimization of the PHC and CFG composite pile for the Escort Center project. The application results and the problems encountered are analyzed with the approach to solve the problems put forward, which has produced good returns.
