Construction process for arched cylindrical-shaped latticed shell provided with arched steel grid jig frame by adopting slippage installation

The invention discloses a construction process for an arched cylindrical-shaped latticed shell provided with an arched steel grid jig frame by adopting slippage installation. The construction process comprises following steps: (a) installing a slippage tool structural system; (b) installing an arched steel grid jig frame; (c) installing a slippage power system; (d) adjusting the longitudinal position of the arched steel grid jig frame; (e) installing the steel latticed shell of an arched cylindrical-shaped raw-material closing field; (f) dismounting a construction platform; (g) dismounting an arched steel grid load-bearing frame and arch foot supports; (h) dismounting the slippage power system; (i) dismounting the slippage tool structural system.The construction process for the arched cylindrical-shaped latticed shell provided with the arched steel grid jig frame by adopting slippage installation has following beneficial effects: the arched steel grid jig frame is reasonably arranged and technology of slippage tool structural system is adopted so as to be favorable for improving working efficiency, shortening working period, saving material, reducing construction cost and enhancing safety guarantee; and furthermore, adverse influence upon simultaneous construction of the lower portion of the steel latticed shell and other professional engineering projects is reduced to the minimum level during engineering construction of the steel latticed shell so that the overall working period is further shortened.
