Production And Application And Development Of Large Diameter Prestressed Concrete Pile

Large diameter prestressed concrete tubular pile is one of the new type of pile foundation structure developed in the period of sixth five-years plan, the category and specifications of this kind of concrete tubular pile improved continually from the only one Al type to A,B,C three category including seven types with the development of harbor industry, and applied in more than forty large scale harbor and bridge projects. The advantages of this product such as better structure performance, lower investment and higher construction speed were fully embodied in such projects.This paper present the pile development and research technology, application and new product research process combined with a lot of project application examples, meanwhile put forward some technical measure to improve and control the pile section fabrication quality and optimize the technology and also describe the technical matter related to tubular pile construction.
