成となっている。FIG. 5 is a longitudinal sectional view of an operation floor portion of a turbine building in a conventional nuclear power plant. A structure in which a turbine portion 2 serving as a head of a steam turbine (a low-pressure steam turbine in the illustrated example) is supported on an operation floor beam portion 1 of a conventional steam turbine support frame, and a condenser 3 is continuously provided below the turbine portion 2. Become. A moisture separator / heater 5 is disposed below the operation floor 4 composed of the top surface of the steam turbine support base, and is evaporated by the heat of a reactor (not shown). Vapors are separated here by moisture when flowing from
The heated steam is supplied to the low-pressure steam turbine 2. The steam heated by the moisture separation heater 5 is supplied to the low-pressure steam turbine 2 through a cross-around pipe 6, but conventionally, the cross-around pipe is drawn out above the operation floor 4, and the low-pressure steam turbine 2 is connected.

外形寸法は、通常6.8m×3.65m×0.56mにもなり、これを
鉄板で構成するためその総重量は500tにも達する。In the case of a nuclear power plant, since the steam flowing through the cross-around pipe 6 may have radioactivity, the cross-around pipe 6 exposed above the operation floor 4 may be used.
Further, a shielding structure 8 is provided to shield radioactivity from the steam valve 7 for protecting the pipe 6. The outer dimensions of the shielding structure 8 are usually 6.8 mx 3.65 mx 0.56 m, and since it is made of an iron plate, its total weight reaches 500 t.

ことが可能となる。When disassembling the low-pressure / high-pressure steam turbine for periodic inspection, the disassembled parts must be placed on the operation floor. Recent turbine buildings have been downsized and the operation floor area has been reduced. When disassembling the low-pressure / high-pressure steam turbine during periodic inspections, cleaning and decontamination work, etc., it is necessary to plan in advance which disassembled parts should be placed in which temporary installation location (laydown area), unless the work is planned in advance. Can not do. Therefore, the wider the operating floor, the more time is allowed in the plan, the more flexible the work becomes, and the faster the work becomes.

ン２の接続部分を覆うだけで良くなる。However, on the operation floor, the shielding structure 8 occupies a large area in the nuclear power plant, which hinders the speeding up of the operation. Techniques for reducing the area occupied by the shielding structure 8 include, for example, the technique described in JP-A-61-272404, JP-A-61-241408, and JP-A-62-28.
In the technique described in Japanese Patent No. 7190, the cross-around pipe 6 drawn from the steam turbine 2 is placed at the end of the operation floor beam 1 so that the steam valve 7 shown in FIG. It is bent below the operation floor 4. Thus, the area occupied by the shielding structure 8 only needs to cover the connection between the cross-around pipe 6 and the steam turbine 2.

従って、定期点検等でのインダウンエリアが制限され、
定期点検等の工程を長くさせる要因になる。The turbine building is being constructed under severe seismic conditions. FIG. 6 is a sectional view of the operation floor beam 1 shown in FIG. The operation floor beam portion 1 is usually made of reinforced concrete, and a reinforcing bar 9 provided in the outer peripheral portion in the longitudinal direction prevents deformation in the tensile direction, and a rib 10 collects the reinforcing bar 9 and prevents shearing. And the concrete 11 of the main body prevents deformation in the compression direction. In the operation floor beam 1 having such a structure, the width t of the operation floor beam 1 cannot be reduced so much because it is necessary to increase the seismic resistance. Therefore, even if the above-mentioned conventional technology is adopted, the area of the connection portion between the turbine 2 and the cross-around pipe 6 projecting above the operation floor becomes large, and the area that cannot be used at the time of periodic inspection or the like can be made considerably large. Problem.
Therefore, the in-down area for periodic inspections is limited,
This is a factor that lengthens the process of periodic inspections.
本発明の目的は、定期点検等を迅速に行うことができ

プラントと蒸気タービン支持架台を提供することにあ
る。An object of the present invention is to provide a power generation plant and a steam turbine support gantry that can have a wide laydown area so that periodic inspections and the like can be performed quickly.
上記目的は、操作床面より下側で上記タービンに接続

でコストの低減および軽量化を図ることも可能となる。With the above configuration, the entire cross-around pipe in addition to the steam valve does not protrude above the operation floor, so that a wider laydown area is secured. Further, when applied to a nuclear power plant, the steam turbine support base also serves as a shield, so that not only a shield structure is not required but also a better shielding effect can be obtained. Further, since the overall length of the cross-around tube is short, the cost can be reduced and the weight can be reduced.
以下、本発明の好適な実施例を第１図から第４図を参

る。FIG. 1 is a longitudinal sectional view of a steam turbine operation floor portion of a turbine building constituting a nuclear power plant according to one embodiment of the present invention. The operation floor beam portion 20 of this embodiment is provided with a through hole, which will be described in detail later, so that the cross around pipe 6 connecting the moisture separation heater 5 and the steam turbine 2 can be inserted through this through hole. . Since the connecting portion between the cross-around pipe 6 and the steam turbine 2 is provided below the operation floor 4, the entire cross-around pipe 6 has a structure buried under the operation floor 4, and around the head of the steam turbine. Does not protrude, and the shielding structure 8 shown in FIG. 5 becomes unnecessary.

11 is poured to make the operation floor beam section 20. At this time, the concrete 11 is poured into the through-hole 22 provided in the box-shaped steel beam 21 through the sleeve tube 23 so that the concrete 11 does not flow into the inside of the sleeve tube 23.

６の長さも短くなり、配管物量も少なくなり、コストや
重量的にも有利になる。The steam turbine 2 is disposed on the steam turbine supporting base thus formed, and the cross-around 6 drawn from the moisture separation heater 5 is inserted into a steam inlet provided below the floor of the operation floor 4 of the steam turbine. When connecting, the cross-around pipe 6 is connected to the steam inlet of the steam turbine through the sleeve pipe 23. Therefore, the cross-around tube 6 does not protrude above the operation floor 4, and the laydown area of the operation floor 4 can be widened. Although this embodiment is an example applied to a nuclear power plant, in this case, since the operation floor beam 20 itself also serves as a radiation shield,
The cost of the structure can be reduced as compared with the conventional case where a shielding structure is separately provided, and it is advantageous to employ this embodiment in terms of weight. In addition, the length of the cross-around pipe 6 is reduced, the amount of piping is reduced, and the cost and weight are improved.

施例でも、第２図に示す実施例と同様の効果がある。In the above-described embodiment, the reduction in strength caused by providing the through holes 22 in the operation floor beam portion 20 is reinforced by providing the steel frame 21 in the beam portion. However, a decrease in strength due to the through-holes may be prevented by increasing the structure of the reinforced concrete beam itself or increasing the number of reinforcing bars without reinforcing with steel frames. FIG. 4 is a cross-sectional view of the operation floor beam portion 24 according to this embodiment. In this embodiment, the structure is the same as that of the conventional beam portion 1 (FIG. 6), but the number of the reinforcing bars 9 is increased and the size of the beam portion is made larger. Further, a sleeve tube 23 for inserting the cross-around tube 6 is provided. This embodiment also has the same effect as the embodiment shown in FIG.

図れるという効果がある。ADVANTAGE OF THE INVENTION According to this invention, since a cross-around pipe | tube does not protrude and is exposed on an operation floor upper part, a laydown area at the time of a periodic inspection etc. can be made large, workability improves, and a periodic inspection etc. can be performed quickly. It is possible to do. Further, since the length of the cross-around pipe can be shortened, the amount of pipes can be reduced. In addition, when the present invention is applied to a nuclear power plant, the shielding structure can be shared with an operation floor having a higher shielding effect than separately provided, so that there is an effect that safety can be improved.
