摘要： PROBLEM TO BE SOLVED: To drive a prefabricated pile under a low altitude head condition without requiring a large device.
SOLUTION: In the initial excavating step 10, a hollow first pile is held by a pile holding device and erected, an excavation rod is inserted into the first pile, and a vertical hole having a larger diameter than the first pile is excavated in a ground. In a pile joint step 12, an intermediate joint excavation rod inserted into a second pile is connected to the excavation rod, the second pile is connected to the head of the first pile, and the second pile is lifted from a pile driver to which the intermediate joint excavation rod is attached. In a pile settling step 14, the holding of the first pile by the pile holding device is released, and the first pile and the second pile are settled into the vertical hole while excavating the vertical hole by the excavation rod. In a foot protection formation step 16, the pile is held by the pile holding device when the front end of the first pile reaches a predetermined position, and after a foot protection is formed by filling and stirring a foot protection fluid while excavating the vertical hole by the excavation rod, the excavation rod is pulled up. In a pile foot protection step 18, the front end of the first pile is settled into the foot protection.
