Beschreibung
Zusammenfassung:	The present disclosure discloses a shell expansion yield stress anchor cable and construction method thereof. An upper end of the shell expansion anchoring part is fixedly installed with the variable-section yield stress anchor cable, and a lower end of the shell expansion anchoring part is fixedly installed with the anchor. The hollow metal tube is arranged in a middle of the anchor cable body, and an outer part of the hollow metal tube wraps the high-strength tapered tube; an outer side of the anchor cable body wraps the variable-section threaded sleeve through the adhesive. The present disclosure is mainly applied to the water-rich tunnel, especially the anchoring support of the high-stress and large-deformation water-rich underground engineering. The variable cross-section allows the compression anchor cable, the shell expansion anchoring part, the anchor and the backing plate to form an anchoring technology that integrates rapid anchoring, compression support and grouting protection.
