Description

Steel strand anchoring end structure Technical Field The utility model relates to the field of steel strand connection, in particular to a steel strand anchoring end structure. Background The construction of the inclined shaft and the vertical shaft of the hydroelectric engineering is usually carried out by taking a steel strand as a bearing wire, conventionally directly anchoring one end of the steel strand in concrete, carrying out anchoring construction by adopting concrete is difficult, if the anchoring point is deviated, correction is difficult, the steel strand anchoring end structure is fixedly connected with surrounding rock through an anchor rod, and bearing capacity is transferred to the surrounding rock after the steel strand is connected with an anchor rod connecting plate through a pin shaft. Because the pin shaft is adopted for connection, the steel strand is convenient to assemble and disassemble and can be repeatedly utilized, so that the work efficiency is improved and the cost is reduced.
