After adjustment is in place good can installation connecting element, sequence of construction is：Ring secondary beam (13) is --- ring secondary beam (13) welding --- in place
--- circumferential panel is in place, and --- bolt connection --- welding of end channel steel --- connects circumferential panel weldering for lossless commission
Connect the fastening of --- lossless commission --- high-strength bolt；
When ring secondary beam (13) is assembled, positioned using double plate；Ring secondary beam (13) and cladding boards (15) use truck crane or 1# tower
It hangs.
5. AP1000 superposed type dome spelling technique according to claim 1, it is characterised in that：The specific steps of the technique
Including：Moulding bed superstructure is removed, protective plate/wire mesh/diffusor entry module (5) platform for lining is assembled；Remove moulding bed
When, first tear the crossbeam and fashioned iron diagonal brace between the steel column of outer ring open, after tear diagonal brace between Internal and external cycle steel column open, then remove outer ring steel column
Upper semisection, then remove inner ring steel column between crossbeam and fashioned iron diagonal brace, finally remove inner ring steel column upper semisection；To all
After component dismounting finishes, bracket is installed, and two ring beams (8) are successively installed on the lower semisection of Internal and external cycle steel column, is formed anti-
Backplate/wire mesh/diffusor entry module (5) platform for lining.
6. AP1000 superposed type dome spelling technique according to claim 1, it is characterised in that：The specific steps of the technique
Including：After dome ontology assembly is completed, the introducing of protective plate/wire mesh/diffusor entry module (5) and erector are completed
Make；Protective plate/wire mesh/diffusor entry module (5) monomer is introduced by dome ring beam monomer (2) upper space, is introduced
Work equipment is jack and hanging belt；Introducing sequence is external octagonal monomer --- removable steel plate --- steel column --- steel column in inside
Between diagonal brace.
7. AP1000 superposed type dome spelling technique according to claim 1, it is characterised in that：The specific steps of the technique
Including：After dome ontology assembly is completed, it is completed at the same time upper, annular stair/hoistable platform (6) and passive containment is cooling
The introducing and installment work of structures (7) between system valve；Upper, annular stair/hoistable platform (6) and passive containment are cold
But the introducing selection monomer of structures (7) introduces between system valve or loose mail introduces；It is introduced if monomer, last Pin need to be reserved
Radial girders monomer (3)；If loose mail introduces, last Pin panel need to be reserved；The mode no matter introduced is loose mail or monomer, is introduced
Work equipment is the hanging belt and jack of suitable tonnage.
