[0028] The connection component 8 comprises:

[0029] Vertical steel bars 8-1, the vertical steel bars 8-1 are several, each with an equal fillet fixedly inserted on the connecting block 6, the lower end of the vertical steel bar 8-1 is fixedly inserted into a slot opened on the pile column 2, and a chamfer 9 is provided at the opening of the slot, which can provide guidance for the vertical steel bar 8-1 in the process of being inserted into the slot, and each adjacent vertical steel bar 8-1 is connected by a connecting steel bar 8-2;
