Description

Steel strand prestress double-embossing anchor Technical Field The application relates to the technical field of anchors, in particular to a steel strand prestress double-embossing anchor. Background The embossing head of the prestressed anchor cable is formed by processing one end of the anchor cable through a hydraulic pushing mode of a jack by a bridge cable penetrating machine, and the parameters of the embossing head generally comprise embossing length, embossing diameter and embossing voltage angle. The jack transversely compresses the anchored steel strand wires, and different compression footage can form different embossing head specifications.
