PURPOSE: A composite pile with a core restriction structure caused by the integration of a steel pipe pile and a hollow concrete pile is provided to reduce construction time by using a hollow concrete pile manufactured in a plant when the composite pile is manufactured. CONSTITUTION: A composite pile with a core restriction structure caused by the composition of a steel pipe pile and a hollow concrete pile comprises a steel pipe pile(11), a hollow concrete pile(21), and filler(22). The steel pipe pile has a circular cross section. The hollow concrete pile has a smaller outer diameter than the inner diameter of the steel pipe pile and is inserted into the steel pipe pile. The gap between the inner surface of the steel pipe pile and the outer surface of the hollow concrete pile is filled with the filler to integrate the steel pipe pile with the hollow concrete pile. |
