The present invention is a method of connecting and constructing underground piles. The method of connecting and constructing ground piles according to the present invention includes: a step of manufacturing a lower pile, which has a through-hole horizontally passing through a position away downward from an upper end thereof and a weld metal fitting coupled to a circumference of the upper part thereof, and an upper pile having a weld metal fitting coupled to a circumference of a lower end thereof; a step of perforating a pile hole in an underground position into which the upper pile and the lower pile are embedded and embedding a casing; a step of allowing a hanging rod to pass through the through-hole so that both ends of the hanging rod protrude from an outer surface of the lower pile to the outside; a step of inserting the lower pile into the pile hole until the hanging rod is locked on the upper part of the casing; a step of stacking the upper pile on the lower pile in order to come into contact with between a lower surface of the upper pile and an upper surface of the lower pile; a step of weld-jointing a lower end of the upper pile with an upper end of the lower pile; and a step of further deeply inserting the lower pile into the pile hole after pulling out the hanging rod in a state where an assembly of the upper pile and the lower pile is held. |
