After the arrangement of reinforcement end of job of the RCCV outside, outboard template framework 82, casting cement in the space that the pressure restraining chamber sleeve 16 by this outboard template framework 82 and RCCV sleeve 10 is surrounded are installed in the outside of RCCV outside arrangement of reinforcement 12.At this moment the RCCV sleeve 10, and the pressure restraining chamber sleeve 16 that is used as the cylindrical portions may sleeve constitutes the inner side template framework.Behind casting cement, pressure restraining chamber sleeve 16 is subjected to the auxiliary of T type fixator 13, and is integrated with inboard arrangement of reinforcement 11 of RCCV and arrangement of reinforcement 12 formation of the RCCV outside, is carried out reinforcing.
Moreover, parallel mutually with the arrangement of reinforcement operation and the concrete depositing operation of RCCV outside arrangement of reinforcement 12, on the nuclear reactor buildings heelpiece 4 of nuclear reactor buildings 1, nuclear reactor pressure container supporting base 5 is set.Near in factory or the construction site ground (on the platform) is divided into pedestal epimere 5a to this supporting base 5 at least and hypomere 5b carries out the building site assembling in addition, moves into then in the nuclear reactor buildings 1 to install and fix.
Pedestal epimere 5a as shown in Figure 6 and carrier ring sleeve assembly (being designated hereinafter simply as the DF sleeve assembly) 85 be assembled into an integral body together.DF sleeve assembly 85 is to be assembled into an integral body by the plate-shaped separators layer arrangement of reinforcement body 86 that constitutes carrier ring 8 and seal pad 30, inner supporting structure spare 87 and dividing plate sleeve 17, constitutes integral structure spare.This DF sleeve assembly 85 is provided with and is installed on the pressure restraining chamber sleeve 16 of pedestal hypomere 5b and RCCV sleeve 10.DF sleeve assembly 85 has the pedestal epimere 5a that fuses in interior all sides, and this pedestal epimere 5a is set on the hypomere 5b of RPV supporting base 5.Inner supporting structure spare 87 is being arranged to radial as many inner supporting structure spare materials 88 of strength member and constituting, and DF arrangement of reinforcement body 86 is combined radiation arrangement of reinforcement 89a and garden week arrangement of reinforcement 89b and constituted.
Be arranged on the DF sleeve assembly 85 on the pressure restraining chamber sleeve 16, it is fixed by complete all welding diaphragm sleeves 17, at the fixing dry-well sleeve 27 as the 2nd section sleeve 10 of RCCV of this dividing plate sleeve 17 surroundings welding.This dry-well sleeve 27 along whole garden week from interior all sides and outer circumferential side soldered and be fixed on the dividing plate sleeve 17 of DF sleeve assembly 85.
As the cylindrical portions may sleeve of the 2nd section sleeve 10 of RCCV, promptly the dry-well sleeve 27, and as the inboard arrangement of reinforcement 90 of the dry-well of the RCCV inside upper part arrangement of reinforcement outside its sleeve, its structure is identical with the inboard arrangement of reinforcement 11 of RCCV with RCCV sleeve 10 illustrated in figures 1 and 2.Join with near the same enterprising luggage in ground (storeyard platform) in factory or the construction site of Figure 1 and Figure 2.The inboard arrangement of reinforcement 90 of dry-well sleeve 27 that is assembled into and dry-well utilizes the lifting auxiliary hook beam 66 of crane shown in Figure 3 65 to lift, and be placed on the carrier ring 8 of nuclear reactor buildings 1, utilize lifting auxiliary hook beam 66 to make it keep along entire circumference dry-well sleeve 27 being welded on the dividing plate sleeve 17 by the lifting state.
Dry-well sleeve 27, carry out from interior all sides and two aspects of outer circumferential side, but no matter be only to have which side according to the legal provisions of atomic energy aspect along welding on dividing plate sleeve 17 on every side, all has enough weld strengths.Before the weld job of dry-well sleeve 27 finished, what can not rise to RCCV arrangement of reinforcement under the carrier ring 8 drew the connection operation mutually.Because the welding of dry-well sleeve 27 is connected the several 10 day time of operation needs with inboard the drawing mutually of arrangement of reinforcement 90 of dry-well, so, in fact can not utilize crane 65 to make the inboard arrangement of reinforcement 90 of dry-well under the lifting state, keep several 10 day time.
Therefore, as shown in Figure 5, prepare prop 91, replace crane that dry-well side arrangement of reinforcement 90 is lifted with this prop 91.Lifting is after inboard arrangement of reinforcement 90 falls to hanging down to dry-well sleeve 27 with as RCCV inside upper part arrangement of reinforcement dry-well to the transfer of prop 91, the inboard arrangement of reinforcement 90 of dry-well is changed into by prop 91 slinging immediately.
On prop 91 is built up in carrier ring 8 the following inboard arrangement of reinforcement 11 of RCCV and the concrete surface between the outside arrangement of reinforcement 12 of having finished construction.Prop 91 is set up many with proper spacing on the Zhou Fangxiang of garden, for example set up 20.The position that prop 91 is set up can not influence that dry-well sleeve 27 that the lifting cantilever 92 by the top lifted carries out weld job and the inboard arrangement of reinforcement 90 of dry-well draws the connection operation mutually.
After the weld job of dry-well sleeve 27 finishes, be connected operation to drawing mutually as the inboard arrangement of reinforcement 90 of the dry-well of RCCV inside upper part arrangement of reinforcement and original RCCV lower inside arrangement of reinforcement 11 as the inboard arrangement of reinforcement of RCCV.In the case, draw mutually to connect arrangement of reinforcement and is connected arrangement of reinforcement 70 with shown in Figure 4 drawing mutually and equally forms steppedly, it is identical that the drawing mutually of the RCCV inboard arrangement of reinforcement 11 of its operational method and inboard heelpiece grafting muscle 63 and pressure restraining chamber sleeve 16 is connected operation.After the drawing mutually of the inboard arrangement of reinforcement 90 of dry-well connects the arrangement of reinforcement end of job, build a kind of as the operation between the dry-well outside arrangement of reinforcement 93 of RCCV outer upper arrangement of reinforcement with framing scaffold (end illustrates among the figure).Set up this operation framing scaffold, begin to carry out the arrangement of reinforcement operation of the RCCV outside, at the outer circumferential side assembling dry-well outside of the inboard arrangement of reinforcement 90 of dry-well arrangement of reinforcement 93.At this moment, before the arrangement of reinforcement operation of the RCCV outside, remove prop 91, if but do not influence this outside arrangement of reinforcement operation, so also can preserve same as before, imbed in the concrete.
Like this, what Fig. 2 was extremely shown in Figure 5 is: near the ground in factory or the construction site (on the storeyard platform) is at the inboard arrangement of reinforcement 11 of the outside of RCCV sleeve 10 assembling RCCV in advance, make integral structure, lift RCCV sleeve 10 (comprising dry-well sleeve 27) and inboard arrangement of reinforcement 11 thereof (comprising the inboard arrangement of reinforcement 90 of dry-well) after the assembling simultaneously, hang in the construction site and install.The installation method of the inboard arrangement of reinforcement 11 of this RCCV sleeve 10 and RCCV can hang in arrangement of reinforcement 11 in the RCCV and the RCCV sleeve 10 of not buckling.Therefore, can save building and the inboard arrangement of reinforcement operation of RCCV of framing scaffold that the inboard arrangement of reinforcement operation of RCCV in the construction site uses, thereby can correspondingly shorten the completion time of project significantly.
Moreover, (during the sleeve 16 of pressure restraining chamber is grafting muscle 63 to the inboard arrangement of reinforcement 11 of RCCV in inboard arrangement of reinforcement 11 of the RCCV of lifting and the construction site, be the inboard arrangement of reinforcement 11 of RCCV of bottom of carrier ring 8 of constructing during dry-well sleeve 27) draw mutually that to connect shape be that each segment length has nothing in common with each other, enlarge gradually, connect with machinery or grouting method, connect the arrangement of reinforcement operation so can draw mutually at an easy rate.
In addition, dry-well sleeve 27 and as inboard arrangement of reinforcement 90 handlings of the dry-well of RCCV inside upper part arrangement of reinforcement in construction site, the RCCV inside upper part arrangement of reinforcement 90 that hangs in sets up prop 91 to be used to support at dry-well sleeve 27 weld periods from the RCCV reinforced concrete section of bottom.Prop 91 lifts after the RCCV inside upper part arrangement of reinforcement 90 that has hung in when using instead in this way, can withdraw crane 65 immediately.And welding and the drawing mutually of arrangement of reinforcement that can carry out dry-well sleeve 27 are connected operation, and the RCCV inside upper part arrangement of reinforcement 90 that has hung in is unaffected.
(2) supporting construction of RCCV partition part
Fig. 6 and Fig. 7 represent to constitute the carrier ring sleeve assembly (DF sleeve assembly) 85 of RCCV partition part.Near this DF sleeve assembly 85 ground in factory or the construction site, for example the enterprising luggage of storeyard platform is joined.The storeyard platform has many kinds, and for example inboard arrangement of reinforcement 11 usefulness platforms of carrier ring sleeve assembly 85 usefulness platforms, RCCV sleeve 10 and RCCV and nuclear reactor pressure container supporting base 5 are used platform.
DF sleeve assembly 85 is assembled into integral structure to dividing plate flat board 17, carrier ring arrangement of reinforcement body 86, seal pad 30 and inner supporting structure spare 87 and makes.Carrier ring arrangement of reinforcement body 86 as shown in Figure 6 and Figure 7, week arrangement of reinforcement 89b combines radiation arrangement of reinforcement 89a and garden, the hypomere 5a of reactor-containment vessel (RPV) supporting base 5 is set and makes its formation integrated in interior all sides of carrier ring arrangement of reinforcement body 86.
The epimere 5a of RPV supporting base 5 is set on the cylindric pedestal hypomere 5b, and pedestal hypomere 5b between form peripheral support step 95.Come the interior perimembranous of DF sleeve assembly 85 is supported by this support level 95.
On the peripheral branches cushion cap rank 95 of RPV supporting base 5, set up the prop 96 that can remove as the temporary support device.This prop 96 is set at above the RPV supporting base 5, and the inner end of the inner supporting structure spare 87 of DF sleeve assembly 85 is supported.Inner supporting structure spare 87 is to be arranged in a plurality of inner supporting structure spare materials 88 radial and to constitute, and the outer end of each inner supporting structure spare material 88 combines and is supported with the shearing resistance stiffener inboard 97 of dividing plate sleeve 17.The shearing resistance of dividing plate sleeve 17 sheet material 98 of putting more energy into makes sleeve pass by radial, to two side-prominent, forms the shearing resistance stiffener inboard 97 and the shearing resistance stiffener outside 99.Between the T type fixator 13 of the shearing resistance stiffener of dividing plate sleeve 17 outside 99 and pressure restraining chamber sleeve 16, insert temporary support devices 100 such as interim material or lifting jack, prevent shearing resistance put more energy into sheet material 98 and dividing plate sleeve 17 distortion and crooked.
On the other hand, the inner supporting structure spare material 88 of DF sleeve assembly 85 is formed by steel such as H type or I type joist steel, comes the supporting of dangling of seal pad 30 to steel plate system by the below of carrier ring arrangement of reinforcement body 86, and whole loadings of RCCV partition part are supported.When the DF sleeve assembly is hung in, utilize crane 65 that inner supporting structure 87 is lifted by crane, the RCCV partition part is hung in the construction site.
