る。At the nuclear power plant, when the civil works such as site preparation are completed, building excavation and construction work are started.
When the construction work reaches a certain stage, generally, the installation of the plant equipment is started when the building foundation work is completed.

術では、この点考慮されていなかつた。Here, the building structure and the equipment 1 of the nuclear power plant are installed at a factory or at an offshore dock, and then transported offshore. On the other hand, in parallel with this, at the power station site 2, the site for building building structure construction is excavated and the installation position is filled with seawater 6 by using a waterway etc. to lead to the building installation position. Leave. After the transported building is guided to a predetermined position, inside the floating caisson,
In the method of transporting with the building base slab, after pouring seawater 6 on the base slab, the power plant building is sunk and fixed on the base rock by a method such as filling concrete. Therefore, the floating caisson and the expanded building foundation secure the buoyancy of the building, and also serve as a weight by pouring seawater and concrete when sunk and fixed. In addition, since the foundation that supports the building is fixed on the bedrock at the end,
Due to the seismic design, the strength and weight are the same as the existing nuclear power plant building foundation, and the building frame is also the same as the existing nuclear power plant. Therefore, in order to expand the installation range of plant equipment in factories or offshore docks, it is necessary to widen the plane dimensions of the building, or to reduce the weight of the building itself and take buoyancy measures during transportation. Then, this point was not taken into consideration.

版の計量化につながることがわかる。In the conventional nuclear power plant building structure, a concrete or steel caisson is installed in the lower part of the building to replace the building frame and equipment that were constructed offshore at sea, or the building foundation version is used instead of this caisson installation. By increasing the size of itself, it is necessary to provide buoyancy for sea transportation and consider expansion of transportation routes to the site and power station construction points. On the other hand, from the viewpoint of shortening the construction period, widening the range of installation of the building frame and equipment in Dotsk leads to shortening the local construction period and shortening the overall construction period. However, expanding the installation range of this building structure and equipment will increase the loading weight during sea transportation.Therefore, in the conventional method of installing caisson, the size of caisson is too large and the latter building In the method of increasing the size of the base plate itself, the stress of the base plate increases as the size of the base plate increases, and therefore the reinforcing bars of the base plate increase in order to take measures for strength. There was a contradiction that heavier. The relational expression between the stress applied to the building foundation and the basic dimension 1 is shown below. According to this formula, it can be seen that reducing the building base size leads to a reduction in stress and a quantification of the foundation plate.

It requires complicated work such as pouring concrete on the foundation, and once fixed, the building is under construction, in service, and
Throughout the service period, the condition of the site is the same as that of the existing nuclear power plant, and the characteristics of the building transportation concept at the time of construction are not utilized.

原子力発電所建屋基礎構造を提供することにある。An object of the present invention is to quantify the building frame at the time of sea transportation of the building, and to further shorten the construction period by expanding the range of installation of equipment on the upper part of the building. In addition to providing the basic structure, it enables a suitable construction work method for local construction work of the power plant, and also stabilizes the building during the service period, and transports the building at the time of construction even during the decommissioning stage after the service period. It is to provide a nuclear power plant building basic structure that makes use of the concept.

としての効果を高めるものであれば充分である。The building foundation version in a nuclear power plant is, for example, a solid foundation whose inside is 5 to 7 m thick in a reactor building and 2 to 3 m thick in a turbine building and which is filled with concrete and reinforcing bars. The thickness of this building foundation is determined mainly by the strength of the building during an earthquake, but it also plays a role as a counterway against the falling moment of the building during an earthquake. On the other hand, when the building is transported by sea, a bending moment and a shearing force are applied according to the building foundation dimensions and the maximum wave height during shipping, as shown in the above formula, but for these stresses, Reinforcing bars for securing the strength of the building after an earthquake after fixing the building, specifically, the upper and lower reinforcing bars installed in the building foundation, can be used for bearing. Therefore, the main purpose of the basic building version is determined by the seismic design of the building. It can be achieved by the cross-sectional force of the foundation plate and the tensile strength of the reinforcing bar.In addition, the maximum wave height during transportation of the building and the stress according to the building foundation dimensions are determined by the seismic design. It can be handled by the basic version structure. In addition, the role of the building foundation slab as a subordinate is mainly during the operation period of the nuclear power plant, and this is not limited to the concrete that has been conventionally used, and it should enhance the effect as the counterweight of the foundation slab. Is enough.

として新たな発電設備を構築することができる。Easily transport seawater in the building, and install as much equipment as possible on the building for the purpose of shortening the construction process, and
In order to reduce the increase in building basic dimensions as much as possible, it is important to measure the building frame itself. Therefore, the building foundation itself can function as a ballast by providing a building foundation structure that integrates the building skeleton and the caisson for giving buoyancy to the building, and installing a hollow part in this building foundation. . Since this building foundation has already been designed for earthquake resistance, no new construction work such as bar arrangement work will be performed at the time of building construction. In addition, the work of submerging / fixing the main building after transporting the building to the construction site should be done by injecting seawater, etc. into the hollow part installed in the building foundation plate to make the weight of the building more than buoyancy. You can easily proceed with the construction work. After the building has been sunk and fixed, some of the building skeleton and equipment / equipment outside the installation range at the factory and dock have been constructed, or in some cases, all installation has been completed at the factory and dock. For the products, commercial operation will be started after trial operation. After the nuclear power plant is in service, the building can be transported in the reverse order of construction, and the main structure, Takaya and the foundation plate will not remain, so it will be abandoned. A new power generation facility can be constructed to reuse the site after the furnace.

Take measures to reduce overall weight. By reducing the weight, the reactor primary containment vessel 8, the reactor pressure vessel pedestal 11, the temporary steel frame 10, etc., which can shorten the construction period and improve the construction efficiency, can be mounted on the foundation. The basic version equipped with these facilities is transported from the dock to the ocean and transferred to the power plant site 2
Guide to the building installation position inside. As shown in FIG. 2, the building that has been installed to the installation position is filled with seawater into the hollow foundation 7 to increase the weight of the entire building and to sunk and fix the building.
Also, after the completion of this construction, the building's weekside will be filled with landfill soil, and the site conditions will be exactly the same as the conventional power plant. Seawater is filled in the hollow portion 7 of the foundation plate even during the service period so that the foundation plate can serve as a counterweight. In addition, at the time of decommissioning after the service period, a part of the upper building was dismantled in blue
The building transportation during decommissioning can be easily achieved by the procedure completely reverse to the construction sequence described above, such as discharging the seawater inside.

Equipment can be installed. In addition, at the local construction stage, by injecting seawater into the hollow part of the foundation plate, the work of sinking and fixing the building can be easily achieved, and this foundation plate can be used as it is as the building foundation plate during the service period of the power plant. Further, after the power plant is in service, the procedure at the reverse of the construction sequence can be performed to easily achieve the decommissioning transfer after the service period.
