Combining with the construction of pre-tensioning pre-stressed hollow square piles in the Tadee liquid chemical terminal project of Huanghua port,we analyze the control key points of the pre-stressed high performance concrete quality from some aspects,such as the quality of raw materials entering the field,concrete air content,and measurement deviation control of mixing station etc.We also analyze the reasons of a series of quality problems such as large slump loss,large thickness of floating slurry,large protective layer of steel and crack on pile surface in the pre-tensioning pre-stressed square pile concrete construction process,and propose the effective concrete construction quality control measures to ensure the physical quality of the subsequent pre-stressed concrete square piles.
