The invention provides a cable crane bearing
rope ground anchor, comprising a pre-stress rock anchor and a
reinforced concrete anchor wall, wherein, the
reinforced concrete anchor wall is poured on the
rock slope surface at two banks; the pre-stress rock anchor comprises an anchoring section, a free section and an anchor wall anchoring section; the anchoring section is anchored in the
rock body; the anchor wall anchoring section is anchored in the anchor wall; the free section is arranged at the middle part; the construction method of the cable crane bearing
rope ground anchor comprises the steps as follows: (1) the central position of the rock anchor is measured to set out and the position of the anchor wall is also set out by pulling a line; (2) the slope surface of the ground anchor position is excavated, the anchor wall
rebar is installed, meanwhile, the rock anchor hole is remained, and the anchor wall concrete is poured by layer; (3) when the anchor wall concrete achieves more than 85% of the design strength, the construction of the hole-forming rock anchor is carried out according to the remained hole on the anchor wall; (4) the anchor cable is arranged in the formed rock anchor hole; (5) the rock anchor scouring construction is carried out; (6) when the strength of the
slurry of the scouring in the rock anchor hole achieves the design tensile strength, the tensioning of the rock anchor is carried out; and (7) after the tensioning is completed, the free section of the anchor cable is grouted or sealed for grouting.
