X形桩的研发与施工工艺

With the development of pile technology in China, the special shaped pile has become a research focus. Hohai Geotechnical Research Institute developed a new special shaped pile X-section pile, and applied for a patent.This kind of pile has fast constrction, low cost,easy quality control, it could be widwly used in various foundation construction projects, and has good applicaton and popularization values, it is therefore a valuable research topic. Combined with the research work accomplished by author, this paper introduces the development idea and section form of X-section concrete pile self-developed by Hohai Geotechnical Research Institute and describes the equipment development and construction technology for this new type of pile, and hope to provide the bebefical reference for the further generalization of X-section pile.
