Description
The present invention relates to the construction job practices of nuclear electric power generation facility, relate in particular to the construction job practices of nuclear reactor factory building.
Referring now to Figure 12 to Figure 14, is the construction job practices that example illustrates original nuclear electric power generation facility with boiling water type nuclear electric power generation facility.Figure 12 is the principal works progress chart of the construction program of the nuclear reactor factory building in the expression nuclear electric power generation facility.And Figure 13 is the skiagraph of the nuclear reactor factory building state of expression in the process of construction, and Figure 14 is a skiagraph of representing the nuclear reactor factory building that builds up substantially.
As shown in figure 12, relate to the engineering of the construction of nuclear reactor factory building 1, be divided into following two parts substantially: the one, the engineering A (hereinafter referred to as construction work) of construction factory building; The 2nd, the engineering B (hereinafter referred to as electromechanical engineering) of installation plant equipment and electric fixtures in factory building.Construction work A is: at first excavated earth is till making the laccolite of nuclear reactor factory building foundation thereon, and carry out laccolite and check C1, then, from build floor wall engineering A2, the roof working A3 etc. of floor (ground) and wall etc. successively to the factory building upper strata as the heelpiece engineering A1 of nuclear reactor factory building foundation.
On the other hand, electromechanical engineering B is: when the Foundation Design D of nuclear reactor pressure container (RPV) finishes, machine and pipeline etc. is moved into inside, then, progress along with construction work A, along with the progress that bottom engineering E, the RPV of nuclear reactor safety shell (PCV) installs C2, RPV internal construction thing engineering F etc., carry out machine engineering B1, piping engineering B2 and the electrical engineering B3 of each layer of factory building successively from factory building lower floor.Then, adjust, make armamentarium all can guarantee its performance.After these engineerings finish, carry out fuel in the inverse nuclear reaction core pressure vessel and load C3, carry out after the system test G, be running beginning H.
Followingly specifically describe project situation with reference to Figure 13 and Figure 14.
Nuclear reactor factory building 1 is the building that the equipment to direct processing radioactive substance supports, and is necessary condition owing to guarantee not to be subjected to seismic damage, so, use rigid structures, its basis must be set directly on the firm laccolite 2.Therefore, under the very dark situation of the construction place of nuclear reactor factory building 1 laccolite 2, the excavation of ground surface etc. will proceed to till the laccolite 2.And in the construction work of nuclear reactor factory building 1, after being produced on the laccolite 2 as the heelpiece 3 of factory building foundation, the factory building orlop from this heelpiece 3 begins to build principal post and girder class 4 and ground and the wall supporting with it as factory building main structure body.And for the pedestal (RPV basis) 7 that directly supports RPV6 also being set directly on the heelpiece 3 by laccolite 2 supportings, its construction speed parallels with factory building principal post and girder class 4 etc.
Engineering about nuclear reactor factory building 1 inner machinery, pipe arrangement and the electric fixtures of installing, adopt such method, promptly except that main equipments such as PCV5, generally, the construction work of nuclear reactor factory building 1 proceeds to respectively to a certain degree at each layer of factory building, the wall of each layer of factory building and the intensity of ceiling are able to install after machinery, pipeline and the electric fixtures, begin respectively to move into and install machinery equipment.And, in order to improve the mechanical efficient of machinery equipment and pipeline etc., also can adopt such method, promptly when each layer ceiling placing of concrete, with reinforcing bar and deck panels as mould plate, before this ceiling mould plate engineering, equipment to be installed is transported on the floor that has abundant intensity, before reaching requirement, the dull and stereotyped intensity of ceiling just can begin mechanical engineering earlier.
In the construction work A and electromechanical engineering B of the nuclear reactor factory building 1 of nuclear electric power generation facility, in roomy factory building scope, arrange many big and small machinery equipments, and, this plant engineering goods and materials amount is very big, so be provided with the transport crane of the inside and outside contact of factory building, i.e. goliaths such as pillar crane 8 that only uses at construction period and crawler crane 9, be used for above-mentioned machinery equipment moved in the factory building and install, so that the engineering goods and materials are moved into and taken out of, perhaps above-mentioned machinery equipment is transported in the factory building in advance.
Moreover, in the nuclear reactor factory building 1 of nuclear electric power generation facility, as the equipment of factory building main body works and fuel and the equipment relevant with fuel in the RPV6 are installed mainly, in order mainly in RPV6, to handle materials etc., building later stage installation bridge crane 10 as shown in figure 14 simultaneously with fuel treatment ground (running operation floor) 11.This bridge crane 10 is installed upward from running operation floor 11, and, owing to itself be quite heavy machine, so, as mentioned above, after the dull and stereotyped and wall on this of running operation floor 11 and ceiling built up by wall and ceiling engineering, crane 10 was installed on the crane runway set on the wall side face portion 12.Roof 13 is erected at the top of bridge crane 10.And later on for guaranteeing dynamo-electric construction works, installing engineering (the RPV internal construction thing engineering) F that carries out with the nuclear reactor internal works is the main purpose construction project.
Moreover special open job practices described in the clear 64-61688 communique and construction job practices shown in Figure 15 are adopted in the construction of the nuclear electric power generation facility in past.
It is after the ground of nuclear reactor factory building the superiors floor has formed mobile job crane to be arranged on the ground of this superiors' floor that the spy opens the described method of clear 64-61688 communique.
Moreover Figure 15 is the figure of the construction job practices of expression nuclear electric power generation facility in the past, and this is so-called all-weather construction method.After basic heelpiece 32 constructions of nuclear reactor factory building 31 finish, at first set up framework reinforcing bar post 33, many interim crane runways 34 and interim crane 35 are installed on this framework reinforcing bar post 33, utilize this interim crane 35 and be installed in outdoor interim goliath 36, carry out moving into and installing engineering of various goods and materials and equipment.The nuclear reactor factory building 31 of Jian Sheing because dismountable roof 37 has been installed, is provided with exterior wall maintenance tarpaulin (not having diagram) like this, covered by roof 37 and exterior wall maintenance tarpaulin, so, weatherproof, can construct in nuclear reactor factory building 31 inside, be the all-weather construction method.
According to this all-weather construction method, construction work is with the engineering of moving into of moving into engineering and electromechanical equipment of materials, use interim crane 35, or use is arranged on outdoor interim goliath 36, for the time being dismountable roof 37 is removed, goods and materials and equipment, nuclear reactor safety casing component and other electromechanical equipments that construction work is used are moved in the factory building, after moving into, reused interim goliath 36 roof 37 that is removed is restored.
Interim crane 35 has about elevating capacity below 5 tons, and the maximum loading that interim goliath 36 has is about the elevating capacity more than 100 tons.
Figure 12 is to the building method in past shown in Figure 14, and as mentioned above, bridge crane 10 is terminal stages of factory building engineering, and promptly the later stage of construction period installs, after this with regard to entry into service.So by the period of the system test G before the filling of RPV internal construction thing engineering F decision fuel, the Other Engineering that this project time limit carried out than the same time is late.So have decisive role to rebuilding the whole duration duration of runs of bridge crane 10.
Moreover, can consider just to utilize bridge crane 10 to come carrying large machine etc. from the initial stage of building.But, according to the construction job practices in past, utilize bridge crane 10, the terminal stage of construction work A in earlier stage can not be utilized bridge crane 10 by the time.Therefore, before bridge crane 10 entrys into service, goliaths such as gadget pillar crane 8 that uses in the time of must construction work A being installed and crawler crane 9 are as handbarrows such as machinery equipment and construction goods and materials.
About the installation of goliath, must have and fill enough working spaces so that it is assembled and dismantles, when it is dismantled at that time because along with the progress building of engineering builds up, so may be difficult to guarantee enough working spaces.Moreover, goliaths such as pillar crane 8 and crawler crane 9 since be arranged on outdoor, so be subject to the influence of weather, may be because of weather former thereby be difficult to use.Usually, construction work A with and the goliath used of electromechanical engineering B prepare respectively, but when construction, must coordinate, in order to avoid construction work is affected with crane and the electromechanical engineering scope of application with crane.
Moreover, under the situation of the nuclear reactor factory building 1 of building the nuclear electric power generation facility, require the heelpiece 3 as factory building foundation is arranged on the laccolite 2, but in general laccolite 2 is mostly in underground very dark place, and the stability for factory building also is embedded to underground to factory building sometimes, in these cases, must excavate ground surface, the underground lowest level of nuclear reactor factory building 1 is in liftoff surperficial depths more than 20 meters.
At such workshop building construction initial stage, the path that the construction operation personnel enter operation field generally all uses interim stair equipment (not having diagram).But because the distance from ground surface to underground lowermost layer is very long, so operating personnel's burden is bigger.And when the underground construction operation, worry the anoxic accident, must take into full account the air-conditioning equipment when building, therefore need very big expense.
Moreover all-weather construction method shown in Figure 15 is because weatherproof, so all be effectively for the construction work of factory building and the installing engineering of moving into of electromechanical equipment.Therefore, the construction work of nuclear reactor factory building and electromechanical equipment moves into that installing engineering is staggered to be carried out.That is to say that interim crane 35 is used in moving into of low weight materials, is used to build moving into of goods and materials.When weight surpasses 5 tons the moving into of goods and materials approximately, use and be installed in outdoor interim goliath 36, because the position of moving into is limited, and the weight goods and materials above 5 tons approximately is also a lot, so be restricted, interim goliath 36 that sometimes need not be outdoor just can't be moved into.
Moreover, when utilizing outdoor interim goliath 36 to move into goods and materials, must partly or wholly dismountable roof 37 be pulled down and restore.When pulling down roof 37, must guarantee that there is interim placement place on the roof 37 that is removed.Though in the narrow and small power plant of floor space or the site area that can place is arranged, the ability of goliath 36 is difficult to carry out demolition works when not enough temporarily.
And even the roof has recloser, perhaps semi-automatic or manual mode can be slided in the horizontal direction, yet has following problem.
That is to say, when utilizing outdoor interim goliath 36 to move into, be subjected to wind and rain and snowy the influence.Promptly only when calm or gentle breeze, could utilize goliath 36 that dismountable roof 37 is removed, materials are moved into, again roof 37 be restored after having removed.But the initial stage can not be pulled down roof 37 when wind is big, causes project schedule delay.Even slidable roof though can open and close the roof, can not use goliath 36 when wind is big, also cause project schedule delay.Moreover, though can pull down roof 37,, meteorology after this increases because changing wind-force, the result can not use goliath 36, and not only materials can not be moved into, and roof 37 can not restore, the result causes project schedule delay, and the operating environment in the nuclear reactor factory building worsens.
The influence of wind and rain and snowfall also is like this.Be calm or can use goliath 36 during gentle breeze, when precipitation and snowfall because roof 37 is opened, not only rainwater and snow immerse inner, construction material, equipment, electric fixtures, various machine, precision optical machinery etc. are caused harmful effect, and the major accident that can cause the person to get an electric shock, the result causes project schedule delay, and operating environment worsens in the nuclear reactor factory building.
Moreover, another shortcoming is: when utilizing dress goliath 36 without to move into materials, be suspension rod and 31 collisions of nuclear reactor factory building that prevent interim goliath 36, when arranging interim goliath 36, according to its energy force diagram, the weight and the scope that hang in are restricted.Be that interim goliath 36 mostly has the about elevating capacity more than 100 tons of maximum load, but, for the suspension rod that prevents interim goliath 36 collides nuclear reactor factory building 31, and owing to the length of boom and the angle of interim goliath 36 and the relation that hung in object are provided with, so the factory building certain distance is left in the position of its mounting arrangements.Generally leave several 10 meters of factory building, will reduce to several tons to tens tons according to the energy force diagram owing to different situations so in fact can move into and take out of the weighing load of factory building.
In Figure 15, interim goliath 36 is portable, but the fixing interim goliath of self-supporting, for example pillar crane is set up because its basis separates separately with nuclear reactor factory building 31, so, the same with above-mentioned situation, crane leaves the factory building certain distance.Its result, the fixing interim goliath of self-supporting, for example pillar crane also has such shortcoming, and according to can force diagram, weight and scope that it can hang in be restricted.
On the other hand, the spy opens that clear 64-61688 communique is described to be: form the back on the superiors ground of nuclear reactor factory building mobile job crane is installed on this superiors ground.But this job practices, its shortcoming is: before the superiors ground of nuclear reactor factory building forms, can not be arranged in mobile job crane on the superiors ground, the reactor inner machine be moved into constructing engineering and can not carrying out concurrently of the engineering in the nuclear reactor pressure container and the building nuclear reactor factory building the superiors with this crane.And, in the scope that mobile job crane moves, be difficult to arrange materials and machinery equipment.
The present invention In view of the foregoing proposes, its purpose is to provide a kind of like this construction job practices of nuclear electric power generation facility: it can shorten the whole construction period of nuclear electric power generation facility, that reduces goliath is provided with the platform number, can prevent the influence of weather to construction, be convenient to the operating personnel and enter subterranean layer work, can improve countermeasure that prevents anoxic etc. at first stage of construction.
