Pile construction method, manifold device, and manifold device design method
The purpose of the invention is to provide a pile construction method that can reliably improve pile bearing capacity. Provided is a pile construction method comprising a step of driving a pile by applying vibration with a vibratory hammer while injecting a high-pressure fluid into the ground, wherein one or more high-pressure fluid delivery devices and a manifold device having a cylindrical inner space are disposed, the one or more high-pressure fluid delivery devices are respectively connected to one or more injection holes in the manifold device, and a plurality of discharge holes in the manifold device are respectively connected to a plurality of jet pipe members. With the inner space of the manifold device filled with the high-pressure fluid, the high-pressure fluid is discharged from each of the plurality of discharge holes and, in terms of the discharge rates of the high-pressure fluid discharged from each of the plurality of discharge holes, the difference between the maximum discharge rate and the minimum discharge rate is no more than 5% of the maximum discharge rate.
