Zusammenfassung:PROBLEM TO BE SOLVED: To provide a management method and a management device for a cast-in-place concrete pile construction method, which are advantageous to rationalizing the works of pulling out casing pipes and tremie pipes.SOLUTION: A casing pipe bottom end depth Dc, a tremie pipe bottom end depth Dt, and a concrete top end depth Dk are each detected. Whether it is possible or not to pull out an uppermost casing pipe unit body 12 is determined based on the concrete top end depth Dk, the casing pipe bottom end depth Dc, and the length of the uppermost casing unit body 12. Whether it is possible or not to pull out an uppermost tremie pipe unit body 18 is determined based on the concrete top end depth Dk, the tremie pipe bottom end depth Dt, and the length of the uppermost tremie pipe unit body 18. These determination results are notified. Thus, works of pulling out a casing pipe 14 and a tremie pipe 20 can be performed based on the notified results.
