[0002] PHC pipe piles, or prestressed high-strength concrete pipe piles, are made by pre-tensioned prestressed centrifugal forming technology, and are cured by steam at 10 atmospheres (about 1.0Mpa) and about 180°C to form a hollow cylindrical concrete prefabricated component with a standard section length of 10m, a diameter of 300mm to 800mm, and a concrete strength grade of ≥C80. PHC pipe piles have a high degree of mechanized construction, a clean site, and a good construction environment. There will be no dirty situation of mud flowing all over the ground at the bored pile construction site, which makes it easy to achieve civilized construction, safe production, and reduce safety accidents. It is also an effective measure to improve indirect economic benefits. Core filling refers to pouring concrete into the pipe pile by filling the inner hole of the pipe pile. In addition to improving the construction and stress conditions of the pile top, core filling can also play a certain role in shear resistance. Generally, the length of the core filling is between 1-2m, which can not only strengthen the strength of the pipe pile, but also save costs.
