Description
Technical field
The present invention relates to the manufacture of tun, particularly relate to nuclear power, chemical industry, oil storage or smelt
Manufacture method Deng the tun in place.
Background technology
In large reactor nuclear power station, it will usually use steel containment vessel.Fig. 1 show this greatly
A kind of illustrative examples of the steel containment vessel of type.This steel containment vessel is typically by multiple assembling modules pair
Connecing and form, these assemble module and include intermediate cylindrical cylinder and be positioned at the cover head at cylinder two ends
1 and bottom (head) 5, intermediate cylindrical cylinder can be divided into again multiple cylindrical drum 2,3,4.Steel safety
The overall weight of shell about 3500t.Wherein, upper and lower two end sockets and multiple cylinder ring completion interior diameter are
40m, height is 11.5m to 15.5m, and piece weight is 660t to 800t.
In the construction of steel containment vessel, typically use the smallest group of containment manufacturer
Becoming unit (part) to shape, then single-piece transports nuclear power station job site, executes at nuclear power station
The steel containment vessel at work scene assembles place temporarily and is respectively completed bottom (head), cover head and cylinder ring body
With the assembling of piece attachments, the most successively bottom (head), cylinder ring and cover head are lifted on nuclear island in place
After installation, finally complete the assembly welding of other adnexaes at nuclear island, to complete a complete steel peace
The construction of full shell.

2) steel containment vessel that nuclear power station job site is all built assembles place occupation of land about 65 mu temporarily,
The ratio accounting for the nuclear power station construction production total land area of Qu is up to 5%, seriously ties up nuclear power station construction and produces
The land used space in district, causes nuclear power station construction to produce district's land used nervous.
3) factory of steel containment vessel component part manufactures and the assembling of nuclear power station job site separates,
Constrain the seamless connection between steel containment vessel part manufacture and overall package, restrict whole steel peace
The raising of the construction progress of full shell.
4) it is correlated with place and work facility owing to nuclear power station job site steel containment vessel assembles place temporarily
Configuration and the difference of manufacturer, limit effective enforcement of part factory manufacturing process, increase nuclear power
The labor intensity that job site steel containment vessel of standing assembles, restriction steel containment vessel integral constructing quality
Promote.
5) in nuclear island of nuclear power station, carry out assembling and the welding job of steel containment vessel adnexa, cause friendship
Fork construction operation and high-altitude construction operation increase, and increase and build management cost and managing risk.
