Description

  The present invention relates to a disk-type cushioning material block suitable for embedding disposal of high-level radioactive waste, a method for producing a disk-type cushioning material block, and a method for producing a waste-integrated cushioning material.

  Generally, when radioactive or industrial waste is buried in the ground, it is made of a high-density clay-based water-impervious material in which bentonite or bentonite and aggregate are kneaded for a water-impervious construction that does not leak toxic substances into groundwater. Buffer material is used. There are also various proposal examples regarding such buffering materials regarding such cushioning materials (see, for example, Patent Documents 1 to 4).

  One of the impermeable works that use cushioning materials is the on-site compaction method. This on-site compaction method is a method in which bentonite-based material is directly unwound at a position where an artificial barrier made of a buffer material is constructed, and compacted by a large heavy machine such as a roller. For example, according to Patent Document 5, a method has been proposed in which a high-level radioactive waste is placed in a vertical hole excavated on a tunnel floor and a cushioning material is installed. However, the on-site compaction method has a drawback that a high-density cushioning material cannot be constructed.

  Therefore, as one of the installation methods of the buffer material, as shown in FIG. 26-2, a waste body-integrated cushioning material 103 in which the waste body 101 and the buffer material 102 are integrally molded is constructed in advance in a factory or the like. A method of disposing of the material after it is placed at the burial position and then backfilled is considered. Here, as shown in FIG. 26-1, the cushioning material 102 includes a cylindrical container-shaped cushioning material 102b having a hollow portion 102a having a size for inserting and installing the waste body 101, and a lid shape for closing the hollow portion 102a. Buffer material 102c. Specifically, the cushioning material is CIP-molded into a hollow container shape (cold isostatic pressing method), and then the waste is inserted into the hollow part and then wrapped in a steel container, so that the waste is integrated. Non-Patent Document 1 proposes a method for manufacturing a cushioning material. According to such a waste-integrated cushioning material, the barrier capability is high in the disposal of the waste.

  However, this type of cushioning material covers, for example, a diameter of 2 to 3 m and a length of 3 to 4 m, and enormous pressing force is required to press-mold such a large cushioning material. , Requires large manufacturing equipment.

  For this reason, the block installation method is generally used as a buffer material installation method. This block placement construction method is a construction method in which a buffer material is press-molded in a block shape at a high density in a factory in advance and then transported to the site to be placed. Regarding this block placement method, for example, according to Patent Document 6, an operation method for placing a fan-shaped bentonite block at a predetermined position is proposed as a method of constructing a clay-based barrier on the outer periphery of a circular mine shaft. ing. Further, according to Non-Patent Document 2, a clay-based soil material is pressed to form a high-density molded body block, which is pre-molded into divided sized blocks, which are combined around the cylindrical waste. An example of installation is reported.

  If the block used for the cushioning material is a small block, it can be press-molded with a small amount of energy, so that the manufacturing apparatus can be made compact. However, in the work of placing the produced small block in a facility for burying and disposing, the work time proportional to the number of small blocks is required, so it can be said that it is more efficient to use a large block.

It is comprised from the bentonite-type material 3 as a clay-type poorly water-permeable material integrated with the formwork 2. Here, as will be described later, the disk-type cushioning material block 1 is for blocking the longitudinal side of a waste body such as a high-level radioactive waste to be discarded, and has a diameter of about 0.8 m, for example. Assuming a cylindrical waste body having a length of about 1.7 m, the disk-type cushioning material block 1 is formed as a relatively large block having a diameter of about 2 m and a height (thickness) of about 0.6 m. Yes. In addition, the bentonite-based material 3 is a powder or granular material made of 100% bentonite or a mixed material of bentonite and aggregates such as gravel, etc., and having moisture adjusted.

First, a bottom plate 4 having a large rigidity as an installation surface is prepared, and a metal cylindrical mold 2 is detachably installed on the bottom plate 4 (FIG. 2A). Here, the cylindrical form 2 forms a part of the disk-type cushioning material block 1 and is formed in a predetermined height that should be filled with the bentonite-based material 3 at a high density. In order to prevent the bentonite-based material 3 wound in the mold 2 from spilling out from the cylindrical mold 2, the input mold 5 having the same diameter as the cylindrical mold 2 is placed at the upper end of the cylindrical mold 2. It is installed in a detachable manner (FIG. 2 (b)). Further, the outer periphery of the cylindrical mold 2 and the input mold 5 is supported by a rigid mold support member 6 as indicated by phantom lines so that it can withstand the press pressure in the press process described later. . In addition, when the rigidity of the cylindrical formwork 2 is sufficient, the formwork support member 6 may be omitted.

  Next, the bentonite-based material 3 is unwound in the cylindrical mold 2 on which the input mold 5 is installed (FIG. 2 (c)), and is spread as appropriate (FIG. 2 (d)). And by press-fitting a rigid piston 7 from above (FIG. 2 (e)) and densifying to a predetermined density by pressing the bentonite material 3 filled in the cylindrical mold 2, The bentonite material 3 is integrated with the cylindrical mold 2 (FIG. 2 (f)). At this time, since the dosing mold 5 is provided, the predetermined high density bentonite-based material 3 can be pressed to the position just above the upper end of the cylindrical mold 2. After the pressing process, the piston 7 is retracted, the insertion mold 5 is removed (FIG. 2 (g)), and finally, the cylindrical mold 2 is removed from the bottom plate 4 to obtain FIGS. 1-1 and 1-2. Thus, the disk-shaped cushioning material block 1 with the cylindrical mold 2 is completed.

  3-1 is a plan view showing a disk-shaped cushioning material block with a hollow portion according to Embodiment 1 of the present invention, FIG. 3-2 is a longitudinal end view thereof, and FIG. 4 is a method for manufacturing the same. It is process drawing which shows this like an end view.

  The disk-type cushioning material block 11 with a hollow part according to the first embodiment is used for water shielding of wastes such as high-level radioactive waste to be discarded in combination with the above-described disk-type cushioning material block 1 as appropriate. And two inner and outer cylindrical molds 12 and 2 having the same height and different radii, which are made of metal and concentrically arranged, and a press which is filled between these inner and outer cylindrical molds 12 and 2 and which will be described later And a bentonite-based material 3 as a clay-based poorly water-permeable material integrated with the inner and outer cylindrical molds 12, 2, which are densified by a compression treatment such as the inner cylindrical mold 12. The hollow portion 13 is formed at the center and has a size capable of inserting a waste body at the center.

  Here, the disk-shaped cushioning material block 11 with the hollow portion is for shielding water around the circumferential direction of the waste body by overlapping several pieces, as described later, for example, a diameter of about 0.8 m, When a cylindrical waste body having a length of about 1.7 m is assumed, the disk-type cushioning material block 11 has a diameter of about 2 m, a diameter of the hollow portion 13 of about 0.8 m, and a height (thickness) of about 0.6 m. It is formed as a relatively large block. In addition, the bentonite-based material 3 is a powder or granular material whose moisture has been adjusted. That is, the disk-shaped cushioning material block 11 with a hollow part has the same outer diameter as the disk-shaped cushioning material block 1 and is formed into a donut-like structure having a hollow part 13 by adding a cylindrical mold 12 to the center part. Has been.

  With reference to FIG. 4, the manufacturing method of the disk type | mold buffer material block 11 with a hollow part is demonstrated. Basically, it is the same as the manufacturing method of the disk-type cushioning material block 1 described in FIG. First, a rigid bottom plate 4 serving as an installation surface is prepared, and metal cylindrical molds 12 and 2 are concentrically mounted on the bottom plate 4 so as to be detachable (FIG. 4A). Here, the inner and outer cylindrical molds 12 and 2 form a part of the disk-type cushioning material block 11, and are formed to have a predetermined height that should be filled with the bentonite material 3 at a high density. Therefore, in order to prevent the bentonite-based material 3 unrolled between the cylindrical molds 12 and 2 from spilling out from the cylindrical molds 12 and 2, the same diameter as that of the inner and outer cylindrical molds 12 and 2, respectively. Are placed detachably on the upper ends of the cylindrical molds 12 and 2 (FIG. 4B). Further, the outer sides of the cylindrical molds 12 and 2 and the input molds 15 and 5 are supported by rigid mold support members 16 and 6 as indicated by phantom lines, and the press pressure in the press process described later is used. To endure. When the cylindrical molds 12 and 2 have sufficient rigidity, the mold support members 16 and 6 may be omitted.

  Next, the bentonite-based material 3 is unwound between the cylindrical molds 12 and 2 on which the input molds 15 and 5 are installed (FIG. 4C), and spread as needed (FIG. 4D). )). Then, a doughnut-shaped piston 17 having high rigidity is press-fitted from above (FIG. 4 (e)), and the bentonite material 3 filled between the cylindrical molds 12 and 2 is pressed to obtain a high density to a predetermined density. As a result, the bentonite material 3 is integrated with the cylindrical molds 12 and 2 (FIG. 4F). At this time, since the input molds 15 and 5 are provided, the predetermined high density bentonite-based material 3 can be pressed to the position just below the upper ends of the cylindrical molds 12 and 2. After the pressing process, the piston 17 is retracted, the input molds 15 and 5 are removed (FIG. 4G), and finally the cylindrical molds 12 and 2 are removed from the bottom plate 4 to obtain FIG. As shown in FIG. 3-2, the cylindrical cushioning material block 11 with the hollow portion with the cylindrical molds 12 and 2 is completed.

  As described above, according to the first embodiment, a large-sized disk (diameter: 2 m, thickness: about 0.6 m) is obtained by dividing the cushioning material to be positioned around the waste body into several pieces in the axial direction. Since the mold cushioning material block 1 and the disk-shaped cushioning material block 11 with a hollow portion are manufactured and the metal cylindrical mold 2 or the inner and outer cylindrical molds 12 and 2 are integrally formed, a press or the like Can be manufactured without making the manufacturing apparatus unnecessarily large, and the presence of the metal cylindrical mold 2 or the inner and outer cylindrical molds 12 and 2 can cause damage during transportation and stationary operations described later. The work efficiency can be improved without having to do so.

Here, the end shape of the cylindrical molds 12 and 2 will be described with reference to FIG. Cylindrical formwork 12 and 2 of this Embodiment 1 have the concavo-convex shape which makes the both ends the male and female shape which can be removably engaged with other members in the direction of a central axis. Specifically, as shown in FIG. 5, the convex portion 12a one end over the entire circumference, it is a 2a, opposite concave portion and the convex portion 12a, 2 a the other end over the entire circumference It is formed as 12b, 2b (it goes without saying that this can also be applied to the disk-type cushioning material block 1 that does not use the cylindrical mold 12). Correspondingly, concave portions 4a and 4b that can engage with the convex portions 12a and 2a are formed in an annular shape at radial positions where the cylindrical molds 12 and 2 on the bottom plate 4 are to be placed. . Thereby, the convex shaped parts 12a and 2a can be engaged with the concave shaped parts 4a and 4b and the cylindrical molds 12 and 2 are installed on the bottom plate 4, so that they can be securely fitted into predetermined positions. It is possible to prevent the cylindrical molds 12 and 2 from shifting due to an impact.

  Similarly to the cylindrical molds 12 and 2, the input molds 15 and 5 are formed in a shape having convex portions 15 a and 5 a and concave portions 15 b and 5 b at the both ends thereof. Yes. The convex portions 15a and 5a can be engaged with the concave portions 12b and 2b of the cylindrical molds 12 and 2, respectively. As a result, by placing the input molds 15 and 5 on the cylindrical molds 12 and 2 so that the convex parts 15a and 5a engage with the concave parts 12b and 2b, the fitting molds 15 and 5 are securely fitted and lateral deviation occurs. Since there is no step between the input molds 15 and 5 and the cylindrical molds 12 and 2, the press work by the piston 17 is properly performed up to the inner wall surfaces of the cylindrical molds 12 and 2. Can be done. In the case of using the dedicated insertion molds 15 and 5, the concave shaped parts 15 b and 5 b are not essential, but the cylindrical molds 12 and 2 can be formed by adopting a structure having the concave shaped parts 15 b and 5 b. It can be substituted for the input molds 15 and 5.

  FIG. 6 shows a modification of the end shape of the cylindrical molds 12 and 2. The male and female shapes at both ends of the cylindrical molds 12 and 2 are not limited to the combination of the convex portions 12a and 2a and the concave portions 12b and 2b. For example, as shown in FIG. May be formed as a combination of the inner peripheral convex step 12d and a combination of the inner convex step 2c and the outer convex step 2d (a combination of seal shapes). Correspondingly, at the radial position where the cylindrical molds 12, 2 on the bottom plate 4 are to be installed, the annular recesses are deep enough to engage the outer peripheral convex stepped portion 12 c and the inner peripheral convex stepped portion 2 c. 4c is formed. Accordingly, the cylindrical molds 12 and 2 are installed on the bottom plate 4 by engaging the outer circumferential convex step 12c and the inner circumferential convex step 2c with the wall surface of the annular recess 4c, so that the predetermined position is ensured. The cylindrical molds 12 and 2 can be prevented from shifting due to impact during pressing.

  Further, the input molds 15 and 5 are also a combination of the outer peripheral convex step 12c and the inner convex step 12d of the cylindrical mold 12, and the inner peripheral convex step 2c and the outer peripheral of the cylindrical mold 2. Similarly to the combination with the side convex step 2d, at both ends, the combination of the outer side convex step 15c and the inner side convex step 15d, and the combination of the inner side convex step 5c and the outer side convex step 5d. Is formed over the entire circumference, and the same effect as in the case of FIG. 5 is achieved.

(Embodiment 2)
The disk-type cushioning material block 1 and the disk-type cushioning material block 11 with the hollow portion described above can be manufactured not only by the press method using the piston 7 or 17 but also by a method using a small rammer compactor. The second embodiment relates to a method for manufacturing a disk-type cushioning material block using a small rammer compactor.

  FIG. 7 is a schematic plan view showing an example of a compaction device for producing the disk-type cushioning material block 1 according to Embodiment 2 of the present invention, and FIG. FIG. 8-2 is a front view showing a cross-sectional view after rolling. The compacting device 21 used in the manufacturing method of the second embodiment is configured by aligning a compacting roller 22 as a pneumatic or hydraulically driven compact compactor in the central portion of the cylindrical mold 2 and in a substantially radial direction. Multiple units are provided. These rolling rammers 22 feed the piston downward, for example, at a cycle of about 1 to 5 times per second, so that the lower rolling section rolls the bentonite material 3, and the rolling rammers 22 themselves by the repulsive force. Jumps up. The drop energy of the entire rolling roller 22 is used during the next rolling operation. In this figure, the rolling ranma itself has a mechanism that slides up and down, but the rolling rammer may be attached to the beam material so that it can move up and down, and the lower rolling surface of the rammer is drawn up and down. Can be pressed.

  In addition, a rotating mechanism 26 is provided which has a roller 24 and a column member 25 which are positioned at the outer peripheral position of the cylindrical mold 2 and run on the annular rail 23 installed on the bottom plate 4 at a constant speed in pairs at the diameter position. A substantially rhombic beam member 27 extending in the radial direction of the cylindrical mold 2 between the tops of the pair of support members 25 and rotating in a horizontal plane around the central axis is provided. The plurality of rolling rammers 22 are held by the lower metal fittings 28 with respect to the beam material 27 and supported by the beam materials 27 and the metal fittings 28 so as to be vertically movable individually by a through-hole structure. . As shown in FIG. 8A, each rolling ramma 22 moves up and down at an individual timing, so that the impact is hardly applied to the beam member 27 and the metal fitting 28. Further, since the entire rolling device 21 performs a horizontal rotational motion by the rotating mechanism 26, the bentonite material 3 put into the cylindrical mold 2 is rolled to a uniform density. When the rolling of the bentonite-based material 3 in the corresponding layer is completed, the amount of bentonite-based material 3 corresponding to the next rolled layer is charged, and this rolling is resumed. By repeating the above charging and rolling operation, the disk-type cushioning material block 1 can be manufactured.

  FIG. 9 is a schematic plan view showing an example of a compaction device for manufacturing the disk-type cushioning material block 11 with a hollow portion according to Embodiment 2 of the present invention, and FIG. FIG. 10-2 is a front view showing a cross-sectional view after rolling. The rolling device 31 used in the manufacturing method of the hollow disk-shaped cushioning material block 11 of the second embodiment is basically the same as the rolling device 21 shown in FIGS. 7 to 8-2. There is a difference in that the rolling compactor 22 is arranged only in the region corresponding to the cylindrical formwork 12, 2.

  Here, the manufacturing method of the disk-shaped cushioning material block 11 with a hollow part using the rolling compactor 31 is demonstrated with reference to FIG. FIG. 11 is a process diagram showing the manufacturing method of the disk-type cushioning material block 11 with the hollow portion in an end view. First, a rigid bottom plate 4 serving as an installation surface is prepared, and metal cylindrical molds 12 and 2 are concentrically mounted on the bottom plate 4 so as to be detachable (FIG. 11A). Here, the inner and outer cylindrical molds 12 and 2 form a part of the disk-type cushioning material block 11, and are formed to have a predetermined height that should be filled with the bentonite material 3 at a high density. Therefore, in order to prevent the bentonite-based material 3 unrolled between the cylindrical molds 12 and 2 from spilling out from the cylindrical molds 12 and 2, the same diameter as that of the inner and outer cylindrical molds 12 and 2, respectively. Are placed detachably on the upper ends of the cylindrical molds 12 and 2 (FIG. 11B).

  Next, an amount of bentonite-based material 3 corresponding to one rolling compaction layer is introduced between the cylindrical molds 12 and 2 in which the input molds 15 and 5 are installed (FIG. 11 (c)), and if necessary. And spread out as appropriate (FIG. 11 (d)). Then, the bentonite material 3 put between the cylindrical molds 12 and 2 is rolled using the rolling device 31 described above to increase the density to a predetermined density (FIGS. 11E and 11F). When the rolling of the layer is completed, an amount of bentonite material 3 corresponding to the next rolling layer is introduced between the cylindrical molds 12 and 2, and the bentonite material 3 is again used by using the rolling device 31. The density is increased to a predetermined density by rolling (FIG. 11 (c) to FIG. 11 (f)). By repeating this process as many times as necessary, the bentonite material 3 is integrated with the cylindrical molds 12 and 2 (FIG. 11 (f)).

  At this time, since the input molds 15 and 5 are provided, the bentonite-based material 3 to be input does not spill out. Further, since the input molds 15 and 5 are engaged with the cylindrical molds 12 and 2 without any step, the rolling roller 22 is guided when the rolling mold 22 rolls the nearest part of the cylindrical molds 12 and 2. It also functions as a rail, can roll the bentonite material 3 at a predetermined high density up to the position of the inner walls of the cylindrical molds 12 and 2, and does not damage the upper ends of the cylindrical molds 12 and 2.

  After the rolling process, the rolling device 31 is retracted, the input molds 15 and 5 are removed (FIG. 11 (g)), and finally the cylindrical molds 12 and 2 are removed from the bottom plate 4 to obtain FIG. -1, a hollow disk-shaped cushioning material block 11 with cylindrical molds 12 and 2 as shown in FIG. 3-2 is completed. It is obvious that the same process can be used for both the compaction device 21 and the disc-shaped cushioning material block 1 with the cylindrical mold 12.

  At the time of rolling by the rolling device 31 (the same applies to the rolling device 21), as shown in FIG. 12, the cylindrical molds 12 and 2 are fastened to the bottom plate 4 through, for example, the charging molds 15 and 5. It is preferable to use an anchor 32 as a fixing device to prevent the cylindrical molds 12 and 2 from being displaced due to vibration during rolling. At this time, as described above, the input molds 15 and 5 are installed so that the convex parts 15a and 5a engage with the concave parts 12b and 2b with respect to the cylindrical molds 12 and 2, respectively. Therefore, the tightening and fixing force by the anchor 32 can be reliably transmitted to the cylindrical molds 12 and 2.

Further, with respect to the disk-type cushioning material block 1 and the disk-type cushioning material block 11 with the hollow portion of the first and second embodiments, an uneven shape 33 as shown in FIG. 13, for example, is formed on the inner wall surface of the cylindrical mold 2 .

Place them side by side. Thus, a storage space for the cylindrical waste body 46 is formed by the continuous hollow portion 13 of the three disk-shaped cushioning material blocks 11 with hollow portions. Therefore, as shown in FIG. 14B, a target waste body 46 is installed in the storage space formed by the hollow portion 13.

  Subsequently, one disk-type cushioning material block 1 is transported by the carriage 45 as a lid body and placed side by side on the opening end side of the disk-shaped cushioning material block 11 with a hollow portion located on the opening end side of the storage space. Thereby, as shown in FIG.14 (c), the hollow part 13 (storage space) is obstruct | occluded.

  In FIG. 14, reference numeral 47 denotes a metal lid plate integrated with the cylindrical formwork 2 at the outer surface side end of the disk-type cushioning material block 1. The lid plate 47 may be integrated by welding later to one end of the cylindrical mold 2 constituting the disk-type cushioning material block 1, or a bowl-like shape with a lid plate 47 in advance. The cylindrical mold 2 may be formed, and in the above-described manufacturing process, the cylindrical mold 2 with the cover plate 47 may be formed by filling the bentonite-based material 3 with high density. .

At this time, as shown in FIG. 16, the cylindrical molds 2 of the adjacent disk-type cushioning material block 1 and the disk-type cushioning material block 11 with the hollow part 11 and the cylindrical molds 12 are mutually protruded. Since it engages by the engagement relationship by the fitting of 12a and the recessed shape parts 2b and 12b, engagement becomes reliable and a core becomes difficult to shift | deviate.

  Finally, as shown in FIG. 14 (d), the waste body-integrated cushioning material 41 manufactured in this way is lifted from the stationary base 42 by the lifting device 49 and transported to a desired position.

  As described above, according to the third embodiment, the cushioning material to be positioned around the waste body 46 is formed into a large-sized block that is divided into several pieces, for example, five pieces in the axial direction. The disk-shaped cushioning material block 1 having a structure having the cylindrical mold 2 and the disk-shaped cushioning material block 11 having a hollow portion integrally having the metal cylindrical molds 12 and 2 are used in combination. These disc type buffer material block 1 and disc type buffer material block 11 with a hollow part are placed side by side and aligned, and a waste body 46 is installed in the continuous hollow part 13, and the disc type buffer material blocks 1, 11 are placed. It is possible to easily manufacture the waste-integrated cushioning material 41 having a high barrier capability by simply joining and integrating the adjacent cylindrical molds 2 by welding. Here, the disk-type cushioning material block 1 and the disk-type cushioning material block 11 with the hollow portion are large-sized, but the outer peripheral surfaces and the like are covered with the metal cylindrical molds 2 and 12, and thus are discarded. The body-integrated cushioning material 41 is not damaged during transportation and placement in the manufacturing process.
