本発明は原子力関連ｍ設または一般の化学プランとに使
用されるライニング容器の構築方法に関する。DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for constructing lined vessels for use in nuclear power plants or general chemical plants.

減衰を図る目的で使用されている。(Prior Art) Lined containers lined with metal such as stainless steel are widely used in nuclear power related facilities or general chemical plants. For example, in a nuclear power facility,
Stainless steel lined containers for storing radioactive waste are used to store radioactive waste generated at nuclear power plants and to attenuate radioactivity.

ている。Lined containers with large capacities are being used as power generation capacity increases, and their role is becoming increasingly important. In addition, there is an increasing demand for installation locations in inland areas, primarily in coastal areas.
従来のライニング容器の代表的な２例を第８図から第１
０図を参照しながら説明する。Two typical examples of conventional lined containers are shown in Figures 8 to 1.
This will be explained with reference to Figure 0.
第１の例は第８図と第９図に示すような構造で、ライニ
ング容器が大型化するため大型パネル１を複数枚組立て
て容器を構築する方法のものである。The first example has a structure as shown in FIGS. 8 and 9, and is a method in which a container is constructed by assembling a plurality of large panels 1 to increase the size of the lined container.

１が形成された斜視図を示している。That is, in FIG. 8, the panel 1 is the lining plate 1.
An embedded material 12 is attached to the back surface of the metal plate 1 through a backing metal 13 and a steel plate 15. This embedding material 12 has a mold MA.
14 are used. A leak detection groove 6 is formed between the backing metal 13 and the steel plate 15. The embedded material 12, the backing metal 13, and the steel plate 15 are necessarily integrated by welding 16 at the factory in advance. Lining plate 11 and adjustment lining plate 4
and will be welded on-site. After the connecting material 3 is fastened to the backing metal 13 with bolts and nuts 8, concrete 7 is poured. FIG. 9 shows a perspective view of the large panel 1 formed by connecting the reinige plates 11.
このようにして第１の例では大型のパネル１゜１同志を
直接取付けるのはむずかしいため、つなぎ材３を介在し
て、そのつなぎ材３上に調整ライニング板４を現地で現
物合わせて調整切断してライニング板１１の面を形成さ
せて容器を構築している。In this way, in the first example, since it is difficult to directly attach the large panels 1゜1 to each other, the adjustment lining plate 4 is placed on the connection material 3 with the interposition of the connection material 3 at the site and adjusted and cut. The container is constructed by forming the surface of the lining plate 11.
従って、この容器を構築する場合にはパネル間同志の現
地溶接５の溶接線がそれらパネルの合わせ目に二ケ所つ
まり２本生じている。Therefore, when constructing this container, there are two weld lines for on-site welding 5 between panels at two locations where the panels are joined.

二本となっている。In the second example, as shown in FIG. 10, the adjustment lining plate 4 is interposed between the lining plate 11 and the panel 1 is welded on site 5.
a, and these panels are combined to construct a lined container. Note that the embedded material 12 and the lining plate 11 are factory welded 16 in advance. In this way, in the second example, the large panels 1a and 18 are directly assembled, but the lining plates 11 are not directly welded together, but the adjustment lining plate 4 is used. Therefore, there are two on-site welding lines.

溶接が多くなり、しかも工期の長期化も招いている課題
もある。(Problems to be Solved by the Invention) In order to cope with the increase in size of conventional lined containers, even if large panels are used, two weld lines are generated at the joints of the large panels. Therefore, there is a problem that the on-site construction period is hardly shortened and on-site welding is not reduced. As a result, welding is often performed on-site due to poor quality control, which is the most important quality control for containers, and the construction period is also becoming longer.
また大型化の利得を生ずるまで大きくすることは二本の
溶接線があっても可能ではあるが、その場合は道路を通
る陸上輸送制限を越えｌた寸法としなければならない。It is also possible to increase the size to the extent that there is a gain in size, even with two weld lines, but in that case the dimensions must exceed the limits for overland transportation through roads.

ｑがなくなり、現地溶接品質の保持に労する不利の方が
大きくなる。In other words, sea transportation by ship becomes the only means of transportation. If we manufacture panels with dimensions that can be transported over land,
Since two weld lines are generated at the subdivision, the on-site weld line becomes longer relative to the lining area. Therefore, the benefit of shortening the construction period (
q is lost, and the disadvantage of having to work hard to maintain on-site welding quality becomes greater.

機の近傍にしか設置できない課題がある。Even if it were to be transported by sea because there would be a profit in increasing the size, a large lifting machine would be required for on-site assembly, which would eventually lead to restrictions on construction work. This restriction is due to the timing of the construction of the lifting machine, and if there are only inning containers within the working radius.
The restriction is that H cannot be performed. In other words, there is a problem that the lining container cannot be laid out freely and can only be installed near a large lifting machine.

In a method for constructing a lie 3 container, in which after assembly, concrete is poured for the frame and then welded at the seams of the lining plates of the panel block, a backing metal is welded to the embedded material in advance, and the backing metal is A lining plate is welded to gold to form a single panel, a plurality of the single panels are combined so that there is a single weld line, and leakage detection grooves are formed on both sides of the weld line. do.

志が一致する。(Function) The embedded material is welded to the lining plate, and the embedded material is formed into a frame shape within dimensions that can be transported by land to form a single panel. The mating surfaces of this single panel will be in the correct plane. The edge of the lining plate on the outer periphery of the panel is positioned on the backing plate when the panels are assembled together. The procedure is to assemble with the goal of matching the backing metal and lining plate, and the embedded materials will match.

Leak detection grooves are formed on both sides of the weld line as elements constituting the groove. When assembling panels on-site, it is necessary to match them accurately, but if you match the backing metal and the lining board, the embedded materials will automatically match.

任意でコンクリート７の打設前でも、その後でも良い。In this embodiment, the unit panel 1b constructed as described above is first transported locally by truck, and the first stage is set using a small lifting machine. When setting the second stage on top of that, the lower end of the upper lining plate 11 is placed over the backing metal 13, so that the mating surfaces of the embedding machine 12 naturally match. Repeat this process to assemble the whole thing. On-site welding 5 may be performed before or after pouring concrete 7, depending on the local construction plan.

ｂの組立も簡易である。As is clear from the above embodiments, according to the present invention, only one welding line 5 is required at the seam of panel blocks, so even panels with dimensions that can be transported by land have a ratio of area to welding amount comparable to that of panels transported by sea. can be realized. Also, local panel 1
Assembly of b is also simple.
