Steel strand installation method for overall space corridor lifting construction
The invention relates to a steel strand installation method for overall space corridor lifting construction. The method includes the steps that 1, the two ends of each steel strand are trimmed to be flat, smooth and free of loose strands through a grinding machine; 2, a dredging plate is arranged under a hydraulic lifter, and the positions of dredging plate holes are adjusted; 3, corresponding holes are flush with one another, all the steel strands of the hydraulic lifter penetrate through the hydraulic lifter at intervals in a leftward rotating mode or a rightward rotating mode, a small part of an outer ring is penetrated firstly, then the entire inner ring is penetrated, and then the other part of the outer ring is penetrated; 4, the bottoms of the penetrated steel strands are flush with one another, and the steel strands remaining at the top of the hydraulic lifter are guided out along a guide frame; 5, after the penetrating is conducted, the steel strands are locked through an upper anchorage device cylinder and a lower anchorage device cylinder, and a suspended anchor piece plate is screwed tightly and locked through a bolt; 6, the steel strands are made to penetrate into a ground anchor in sequence and buried in a neat mode, and a ground anchor piece plate locks the steel strands . By means of the steel strand installation method, a basis is provided for overall lifting construction of an ultrahigh overweight large-span space corridor, and the safety of the overall lifting construction of the ultrahigh overweight large-span space corridor is guaranteed.
