Compare in the perform region 42 that a large scale packaged type crane all is set with each unit, the present invention program is advantageous, this advantage is, can reduce the quantity of employed large scale packaged type crane perform region, thereby reduces the investment cost of crane facility.
The method embodiment that uses a large scale packaged type crane progressively to build a nuclear power station below will be described.
Fig. 2 is a process flow diagram, and it schematically shows a standard method process of building a single unit of a nuclear power station.In the method, be used for rock inspection (rockinspection), the hydraulic pressure test 32 of reactor pressure vessel, a construction period 71 of the commercial operation 34 of refuelling and beginning (finish and build after the unit) needs 48 months.Fig. 2 has also schematically illustrated the use step of a large scale packaged type crane 91, and promptly it comprises 51, one work periods 52 an of installation period and a dismounting cycle 53; Also showing one in addition uses large scale packaged type crane 91 that main object is installed into packing into the cycle of unit, for example, packing into the cycle 35 of a RCCV lining (RCCVliner), one big locking condenser (blocked condenser) packs into the cycle 36, pack into cycle 37 and reactor pressure vessel of carbonated drink separating heater packed into the cycle 38.
In the process flow diagram of Fig. 2 of the standard method of having represented to build nuclear power station, begin to build nuclear power station from rock inspection 31, pass through some key steps then, for example hydraulic pressure test 32 and fuel filling 33 reach the commercial operation 34 of beginning at last.
In this embodiment, for the purpose of simplifying the description, need to suppose 4 years to build a nuclear power station (checking 31 to the commercial operation 34 of beginning) from rock, and all be put into the power station and will spend triennium from beginning to be built into main object, no longer need large scale packaged type crane to build this moment.
In the process flow diagram that shows the standard method of building a nuclear power station of Fig. 2, large scale packaged type crane before beginning, is installed in the rock inspection, to carry out the assembling of object, pack into and start working, described object comprises the concrete reinforcement of the enhancing of the bottom substrate that is used for anabolic reaction pile room 1 (reactor block 1 being mounted to cancellated rod-type (bar) module as prefabricated component at building-site), the lining (liner) that is used for containment vessel, and other need be installed into other object in the unit period in the beginning of building.
Use large scale packaged type crane 91 to be installed into specifically being exemplified as of main machine/electric object in the unit: a RCCV lining module, the concrete model of an inwall that is used to form a containment vessel and the piping system that penetrates this reactor safety housing become one therein; A RPV pedestal (RPV pedestal), it is the basis of setting up reactor pressure vessel, and it can be discharged into high pressure steam in the pressure suppression pool when major accident takes place; A RCCV dry-well (dry well) module, pipe system therein, valve member, a syndeton, fender wall and similarly object mutually combine in aggregates; With the lower case of a vapour condenser, a carbonated drink separating heater, the main body of a generator unit stator and a reactor pressure vessel.
In addition, for the method for construction of building nuclear power station is further rationalized, a cancellated bar module, a RCCV top board (top slab) module, a layout bar module and an analog of forming film bottom (diaphragm floor) is also put in the nuclear power station buildings with large scale packaged type crane 91.
Use large scale packaged type crane 91 that the large scale object is installed in the buildings carries out always, up to the hydraulic pressure test 32 that has carried out being used for reactor pressure vessel, large scale packaged type crane 91 oneself moves to a position then, thinks to pack object in the next unit and get ready.
If next unit not in same place, is then dismantled this large scale packaged type crane 91 so that it is moved.
Fig. 3 shows a reference example, does not wherein use the method for large scale packaged type crane of the present invention to build two groups of dimorphism nuclear power station unit (totally four unit).In this embodiment, the difference of the construction zero-time of Unit first and second is 1 year, and the difference of the construction zero-time of Unit the second and the 3rd is 2 years, and the difference of the construction zero-time of Unit third and fourth is 1 year.
It should be noted that the configuration in configuration of buildings this moment and large scale packaged type crane groundwork zone 11 identical with shown in Fig. 1.
Under this kind situation, need two large scale packaged type cranes (crane #1 and #2) to build Unit first and second respectively.More particularly, the large scale packaged type crane (crane #1) that is used to build first module to build first module up to time point 32, carries out the hydraulic pressure test of the reactor pressure vessel of first module in 41 work of the perform region of large scale packaged type crane this moment.Because press construction plan, Unit second was built than first module in late 1 year, therefore just used #2 large scale packaged type crane to build Unit second after #1 large scale packaged type crane uses 1 year.
Like this, the work period overlaid of the work period of a #1 large scale packaged type crane and #2 large scale packaged type crane.
More particularly, after #2 large scale packaged type crane is used to build Unit second, #1 large scale packaged type crane still in large scale packaged type crane workspace 41 continuous workings that are used for first module 2 years.
Also can this thing happens when building Unit third and fourth.
Therefore, do not using under the situation of the inventive method, needing two large scale packaged type cranes 91.
In addition, available identical large scale mobile crane is built Unit the second and the 3rd of sharing the large scale packaged type crane workspace 42 be used to build Unit the second and the 3rd.
In other words, after using large scale packaged type crane construction first module,, there is one to leave unused in the middle of two large scale packaged type cranes to bringing into use large scale packaged type crane to build between Unit the 4th.
Below, the use order of large scale packaged type crane when building each nuclear power station unit will be described by means of the construction example of reference Fig. 4.In this example, use uses the method for large scale packaged type crane to build two groups of dimorphism nuclear power station unit (totally four) by the present invention.In addition, the construction start time of Unit first and second differed 1 year, and the construction start time of Unit the second and the 3rd differs 2 years, and the construction start time of Unit third and fourth differed 1 year.
The large scale packaged type crane 91 that is used to build first module was used to build before Unit second after 1 year, and this large scale packaged type crane 91 just is used for object is put into first module in large scale packaged type crane workspace 41.
Then, for object being put into Unit second, with large scale packaged type crane 91 move to build Unit the second and the 3rd in the shared large scale packaged type crane perform region 42, so can use large scale packaged type crane 91 that the large scale object is put into Unit second.
Beginning to build Unit second to no longer needing large scale packaged type crane to build this section of first module in period, when needs are put into Unit second with the large scale object, large scale packaged type crane 91 can move between large scale packaged type crane perform region 41 and 42, thereby object is put into Unit second.
Equally, in order to build Unit third and fourth, large scale packaged type crane 91 moves so that object is put into corresponding units in large scale packaged type crane perform region (42,43).
Large scale packaged type crane 91 can oneself move between each unit.
Large scale packaged type crane 91 has a counterweight to keep its stability when mentioning an object.
When crane 91 when (or zone) is mobile, can remove counterweight 95 along a path that strengthens for moving in the perform region from large scale packaged type crane 91.
With reference to Fig. 5, the influence that every mobile route 92 (being used for the motion at large scale packaged type crane 91 between Unit first and second) and mobile route 93 (being used for the motion of large scale packaged type crane 91 between Unit the second and the 3rd) are improved by ground like this, make crane under the state that counterweight 95 unloads from crane 91 on motion path when mobile, (ground) should bear the weight of a large scale packaged type crane 91.
In this case, by preparing motion path 92 and 93 along motion path 92 and 93 feeds institute path (yardroad) foundation pressure greater than general road of reinforcement, the weight of the crane of operation thereon can be born in this sample institute path.
Be used for each motion path 92 of large scale packaged type crane 91 and 93 width slightly greater than the width of the motion parts (crawler belt) of large scale packaged type crane 91.
Use a truck to be carried between the perform region, and once more this counterweight is installed on the large scale packaged type crane 91 from the counterweight 95 that large scale packaged type crane 91 disassembles.
For large scale packaged type crane can be moved, can consider that the special path of a ground with a reinforcement of preparation (for example material institute path of Zeng Qianging) in a material institute can be moved large scale packaged type crane 91 along it between the perform region; Also can consider to use large scale packaged type crane to continue to use in the material part of various objectives and move, but not relevant with work, this part is subjected to ground processing effect, for example layer overlay steel plate simultaneously.
An example of the mobile route 96 of large scale packaged type crane 91 in this case has been shown among Fig. 6.
Fig. 6 show when beginning to build Unit the 3rd material user mode.As shown in FIG., be provided with a material institute 21 so that a RCCV lining to be installed, the large-sized module at a scene and analog, the prefabricated object material institute 22 of a reinforcement, one is transmitted material institute 23, a light oil case generates district 24 (light oil tank creation area), a zone that is used to assemble an on-the-spot pond (pool in-situ).
Large scale packaged type crane 91 is motion between workspace 41 that is used for first module and the workspace 42 that is used for Unit the second or the 3rd, and mobile with the part (utilizing) of the material institute that allows the crane process along the ground with reinforcement simultaneously.
In addition, for the material that changes along with the time user mode adapt, can consider in advance to the multi-usage material around the builder's yard ground carry out some enhancings.
In order to make after large scale packaged type crane 91 has moved on to another construction unit, one object is put in the previous construction unit, can consider another whipline to be set in the build area of the construction unit that does not have large scale packaged type crane 91, its load-carrying capacity is used for the auxiliary object of installing less than large scale packaged type crane.
The installation position example of another selectable whipline is seen Fig. 7.
The same with large scale packaged type crane, from the angle of economy, also require to reduce the quantity of selectable whipline.
In example shown in Figure 7, suppose when large scale packaged type crane has moved on to the construction unit area of odd number and packed work into, in the construction unit area of even number then by the work of packing into of selectable whipline.
After finishing the work of packing in Unit second, this selectable whipline is moved to Unit the 4th side.This whipline can be a tower crane or a packaged type crane.
As mentioned above, according to the present invention, can only use a large scale packaged type crane 91 in the above-mentioned construction time interval, to build dimorphism nuclear power station unit (comprising a plurality of unit), though can in two identical construction time intervals, use two large scale packaged type cranes to build this dimorphism nuclear power station unit routinely.
Fig. 8 shows an example that is used for large scale packaged type crane 91 of the present invention.
Near large scale packaged type crane perform region 41 work of this large scale packaged type crane 91 reactor block 1 is with buildings 1 that large-sized module and analog are packed into.
The above embodiments can reduce the purchase cost of crane, the maintenance management expense, and also can be reduced to the expense that large scale packaged type crane is prepared ground.
