Abstract: In the field of civil engineering in China, piles with “screw” technologies are always mistranslated into “screwed pile”, meanwhile, Chinese invention patents related to E02 classification of water conservancy, foundation and dredging are lack of unified standard Chinese terminologies to describe “screw”, which are not constructive for “one belt & one road” and merging the China inventions into the world. This paper uses a term of translation from the screw thread producing methods as the core clue, proposes some suggestions for the translation of relevant words in Chinese and English, and explore new classification system to installation of concrete piles, displacement castinplace concrete pile becoming one of the three key parts among the pile market worldwide.

Key words: Pile with Screw Thread, Screw Thread Producing Methods, One Belt &, One Road, Displacement Cast-in-place Concrete Piles
