Description

Technical Field

[0001] The utility model belongs to the technical field of supporting engineering, and more specifically, relates to a large-tonnage anchor cable tensioning pad and an anchor cable. Background Art

[0002] Anchor cable is a common form of support. During installation and construction, holes are drilled on the rock mass or concrete lining that needs to be supported, and steel strands are inserted. The inner end of the steel strand is anchored in the hole by grouting, and then a tensioning pad is installed at the hole mouth. The steel strand is temporarily fixed to the tensioning pad by anchors, and then the jack is installed on the outer end of the steel strand using anchors, and the jack is placed on the tensioning pad; during tensioning, the steel strand is loaded with tensioning force by the jack, so that the steel strand is stretched. After reaching the target tensioning force, the steel strand is fixed to the tensioning pad by anchors.

[0003] At present, the tensioning pads are basically made of ordinary steel plates, and two angle plates are welded on the inner side of the tensioning pads to make the plate surface direction of the tensioning pads perpendicular to the extension direction of the steel strands. This results in that when large-tonnage anchor cables are under construction, the force applied by the jacks to the tensioning pads is very large, which can easily cause the tensioning pads to bend and deform, and the huge tension on the steel strands will cause plastic deformation at the contact between the tensioning pads and the anchors, that is, the anchors will press grooves on the tensioning pads. This can easily cause changes in the tensioning force and tensioning direction of the steel strands, which poses a safety hazard during tensioning construction and subsequent use.
