Overall jacking construction method for large-area bolt-sphere net rack
The invention relates to an overall jacking construction method for a large-area bolt-sphere net rack. The overall jacking construction method for the large-area bolt-sphere net rack comprises the following steps of (1) determining the position of an assembled plane, and performing land-leveling operation and location paying off; (2) assembling the bolt-sphere net rack on the ground; (3) uniformly arranging large net rack short-distance lifting appliances at supporting points on the upper portion of the bolt-sphere net rack; (4) mounting jacking supports and hydraulic jacks at various jacking supporting points on the lower portion of the bolt-sphere net rack; (5) maintaining bolt-sphere net rack supporting structures on all the jacking supporting points at the same horizontal position; (6) mounting net rack overall jacking difference value measuring devices at the positions of the jacking supports; (7) jacking primarily; and (8) jacking normally. By the overall jacking construction method for the large-area bolt-sphere net rack, overall primary jacking of the net rack is realized, synchronism of the various jacks in an overall jacking process is guaranteed, and skewing of the bolt-sphere net rack due to uneven stress can be avoided.
