摘要

The methods of a drawing device of construction powder injection pile and device with a quadrant combination steel pipe are developed and introduced, according to the experiences of reconstruction besides Huangpu river of Shanghai Lujiazui distraction. The device which has less friction between pile and device is used in the reconstruction to pull 568 powder injection piles and 346 tree piles of construction and achieves good efficiency. Theoretical results are in good agreement with the field experimental results.
