摘要： PROBLEM TO BE SOLVED: To provide a pile construction method for shortening pile construction time by effectively using motive power of a driving motor for an auger excavator, and a pile head part expandably rotating device used therefor. SOLUTION: This pile construction method repeats an auger precedently excavating process for excavating the ground by lowering an auger rod by the prescribed depth while rotating the auger rod by wholly transmitting the motive power of the driving motor for the auger excavator to the auger rod without being transmitted to a pipe pile, an auger pulling-up process for pulling up a tip auger head in a pipe pile tip part by lifting the auger rod and a pile-auger rotatably intruding process for rotatably intruding both up to a depth position exceeding no depth excavated by the precedently excavating process by mutually rotating the pipe pile and the auger rod in the opposite direction by transmitting the motive power of the driving motor to both the pipe pile and the auger rod in this order.
