Design of Sleeve Piling Machine and Finite Element Analysis of the Sleeve Tubes

Abstract

In order to solve the problems of the easy breakage, transport problems and pile holes shrinkage, a sleeve piling machine was designed. It included a fully used pile frame, a novel pile driver and its piling method. The piling machine integrated the advantages of the diesel hammer piling machine and the vibration hammer piling machine. It is suitable for bored piles and compacted piles. Based on the sleeve pile tubes, the diesel hammer and the vibration hammer worked together to drill. Then the reinforcing cage was lifted by the hoister, the pile tubes were pulled and the concrete were poured with the help of the vibration hammer. All of them can avoid the shrinkage of the pile, the break of the pile, and improve construction efficiency. Besides, finite element analysis of the pile tubes were calculated by ANSYS, the results showed that the strength of the pile tubes was satisfied with the requirements of application. The piling machine and the method were feasible.
