The present invention provides a retaining wall construction method using a precast pile forming a retaining wall by combining a wale support connection member capable of mounting a wale on a precast concrete pile and embedding the precast concrete pile after boring a retaining wall hole. According to a proper embodiment of the present invention, the retaining wall construction method includes: (a) a step of overlapping and connecting two band-shaped steel plates, wherein the length of one of the steel plates corresponds to the outer circumference of the precast pile and the length of the other one is same as or a bit longer than the outer circumference of the precast pile, by having a connection section formed at both ends, wherein the two steel plates are not overlapped with each other in the connection section, and of forming screw holes in the connection section at both ends in identical positions and numbers to manufacture the wale support connection member comprising an inner band and an outer band; (b) a step of coupling and assembling a headless bolt to the screw hole after forming one or more the wale support connection members and enclosing the precast pile with the wale support connection members at one or more positions in the longitudinal direction into a circular shape; (c) a step of boring and forming the retaining wall hole on the adjacent ground surface at a predetermined depth using a casing, and embedding the precast pile into the retaining wall hole by drawing the precast pile; (d) a step of performing waterproofing grouting to prevent flowing water on the excavated rear surface of the precast pile, embedded after the casing is taken out of the ground, due to excavation from penetrating into the precast pile; (e) a step of performing the excavation and combining a support member to the wale support connection member (20) exposed from the precast pile; and (f) a step of combining an angle bracket to the support member and installing the wale and a timbering member. |
