At this time, the pile foundation 100 and the joint pile 300 can be respectively formed according to the depth at which the pile is driven into the ground and the height at which the pile driver can piling. If only the pile 100 is not able to reach the predetermined depth of the pile, a plurality of extension piles 200 can be made to fill the insufficient depth.

As shown in Fig. 2A, in the construction of the foundation pile, the piled pile 100 which has been completed by the pile driver 900 is driven into the ground.

If only the pile 100 is reached to reach the predetermined depth of the pile, when the pile 100 is driven into the underground predetermined depth and the pile end cover 140 is still above the ground, the joint pile 300 is placed at the joint portion 330. The driving pile end cover 140 of the pile 100 is coupled to the driving pile 100 by welding the coupling joint portion 330 and the driving pile end cover 140. At this time, the end edge of either the pile end cover 140 and the joint pile 300 may be formed into a chamfered portion, and the chamfered portion 141 of the pile end cover 140 or the chamfered portion 331 of the joint pile 300 may be driven. One performs welding to prevent the welded portion from protruding beyond the circumference of the driven pile 100 and the joint pile 300, thereby increasing the resistance of the pile.

If only the pile 100 is not able to reach the predetermined depth of the pile, it can be connected. The extended pile 200 is continuously driven into the pile 100. When the driving pile 100 is driven into the underground predetermined depth and the driving end end cover 140 is still above the ground, as shown in FIG. 2B, the extending pile 200 is set to the driving pile 100 by the first extended pile end cover 230. The pile end cover 140 connects the first extension pile end cover and the driving pile end cover by welding coupling, so that the extension pile 200 is connected to the driving pile 100. At this time, as shown in a partially enlarged schematic view in FIG. 2B, the end edge of either the pile end cover 140 and the first extension pile end cover 230 may be formed as a chamfered portion, and is driven into the pile end cover 140. Any one of the chamfered portion 141 or the chamfered portion 231 of the first extended pile end cover 230 is welded (the both the driven pile end cover 140 and the first extended pile end cover 230 are chamfered as shown in FIG. 2B), The welded portion is prevented from protruding beyond the circumference of the driving pile 100 and the extension pile 200, thereby increasing the resistance of the pile driving. If the extension pile 200 is not able to reach the predetermined depth of the pile, the extension pile 200 may continue to be continued when the extension pile 200 is driven into a predetermined depth underground and the second extension pile end cover 240 is still above the ground.

When the extension pile 200 is driven into the ground to reach a predetermined depth of the foundation pile and the second extension pile end cover 240 is still above the ground, the joint pile 300 is extended by the joint portion 330 to the second extended pile end cover 240 of the extension pile 200. The joint pile 300 is connected to the extension pile 200 by welding the coupling joint portion 330 and the second extension pile end cover 240. At this time, the end edge of either of the second extension pile end cover 240 and the connection pile 300 may form a chamfered portion, and may be at the chamfered portion 241 of the second extension pile end cover 240 or the chamfered portion 331 of the joint pile 300. Either weld. Further, when piling is continued from the slamming end 340 of the connecting pile 300 to a predetermined position at the lowermost portion of the reinforcing bar joint portion 311 of the connecting pile 300 to reach a predetermined height on the ground, the pile driving operation of the pile is completed.

After the piling operation of the plurality of piles is completed, as shown in FIG. 3A, a plurality of reinforcing bars are disposed at predetermined positions of the cylinders of the connecting piles 300. 311, but the reinforcing bar joint portion 311 may be provided only at the floor position where the construction is currently scheduled, depending on the progress of the construction.
