The invention discloses a recyclable self-anchored anchor rope assembly and a construction method. The recyclable self-anchored anchor rope assembly comprises: an auger anchor head and a steel strand, wherein the auger anchor head comprises a drill bit and a stern tow; the drill bit is hinged to the stern tow through a pin; a drilling rod hole is formed in the middles of the drill bit and the stern tow; anchor heads are arranged at the bottoms of the drill bit and the stern tow; a steel strand pull hole is formed in the upper part of the stern tow; a drilling rod platform is arranged at a tail end of the stern tow; the steel strand penetrates through the steel strand pull hole of the auger anchor head; two ends of the steel strand are fixed on an anchor device through tapered anchor locks to form a U-shaped tension structure; the construction method is shown as the specification. The recyclable self-anchored anchor rope assembly has the beneficial effects that the recyclable self-anchored anchor rope assembly can be anchored by self characteristics and an additional anchoring agent is not needed; in a construction process, an acting force is applied to the tail end of the drilling rod, so that the auger anchor head jacks frontward, and the installation is simple and rapid. After a mission is finished, the anchor device of the anchor rope and the steel strand can be detached and recycled, so that resource reuse is realized.
