Grout-stopping plug for anchorage cables

The utility model discloses a grout-stopping plug for anchorage cables. A silica gel plate is clamped by two high-rigidity PVC (polyvinyl chloride) plates, the two PVC plates and the silica gel plate are fixed by bolts and fabricated into a disc-shaped plug body, reserved round holes through which injection tubes, exhaust tubes and steel stranded wires can pass are symmetrically arranged on the disc-shaped plug body, the disc-shaped plug body is mounted on an anchorage cable and fixed, the PVC plates are provided with reserved PVC plate anchorage cable steel stranded wire holes, reserved PVC plate injection tube holes and reserved PVC plate exhaust tube holes, and the silica gel plate is provided with reserved silica gel plate anchorage cable steel stranded wire holes, reserved silica gel plate injection tube holes and reserved silica gel plate exhaust tube holes, the diameters of which are less than the outer diameters of the anchorage cable steel stranded wires, the injection tubes and the exhaust tubes. The structure is simple, the grout-stopping plug is convenient to use, and is highly applicable, the fabrication cost is low, the grout-stopping effect is good, and the grout-stopping plug can guarantee the grouting pressure. The grout-stopping plug can be used for sealing holes with different apertures for anchorage cables with different structural forms under different grouting pressures, the hole-sealing effect is good, and the economic applicability of the grout-stopping plug is good.
