On account of the torsion of water pipe and wire rope around the pile body during working, the dynamic characteristic analysis of the Pile Extractor components was analyzed and the natural frequency and formation characteristics were studied by using finite element method. The fundamental reason of the torsion of water pipe and wire rope is caused by the(More)
The Pile Extractor of water jetting is one kind of the new developed products and the 3-D modeling and the assembly of its various spare parts were carried by 3DSMAX.The water jetting was simulated by using the granule system. The reasonable structure and the best effect of water jetting flow were attained through the 3-D virtual design and the flow(More)
Based on harnessing the Yellow River, a multi-nozzles pile extractor was developed. Multi-nozzles submerged jets of extracting pile component were simulated numerically by the RAN model and the Ansys software. The reasonable structure was attended and tested by experiment. The simulated numerically results showed that the simulated numerically method was an(More)
