[0018] The waste handling device moving device according to claim 13 is the same as that described in claim 12, characterized in that the rollers are configured to each support one of the sleds. [Effects of the Invention]

[0019] According to the waste container of this invention, the expansion portion of the metal expansion anchor is pushed and expanded by the projection within the anchor insertion hole, and the expanded portion comes into contact with the first tapered portion at the back of the hole, thereby forming a strong anti-loosening structure. As a result, the frame and the end plate can be securely joined by a pushing operation alone, without the need for welding or on-site casting, and assembly work can be easily performed. Furthermore, since the anchor insertion hole has a second tapered portion that expands in diameter toward the entrance side, the metal expansion anchor can be inserted smoothly, and the end plate can be attached to the frame smoothly and easily.

[0020] By providing gripping recesses on a pair of side sections, transport operations using lifting clamps and the like can be easily performed, assembly work can be simplified, and workability can be improved.

[0021] When one end plate is provided with a protruding end plate that extends upward, the protruding end plate functions as a stopper that restricts the movement of containers stacked on top. This prevents misalignment of stacked containers.

[0022] When the length of the frame body with the protruding end panels is formed to be long, the length of the container in the front-rear direction increases, thereby increasing the grounding area and weight, and enhancing the resistance to tipping and movement. As a result, the stability at the column ends can be improved.

[0023] When one bolt is fixed to one end panel and the other bolt is fixed to the other end panel and the two bolts are connected by a turnbuckle, tension can be applied between the end panels, so that it is possible to prevent the end panels from detaching from the frame body due to the weight of the filler and external pressure. As a result, a double restraint structure by combining with a metal expansion anchor can be realized, and the reliability of the joint between the frame body and the end panel and the structural strength of the entire container can be improved.

[0024] When the maximum distance between the inner sides of the connecting members is at least 100 mm, a sufficient space between the connecting members can be ensured, so that a filler such as a curing material can smoothly flow between the connecting members, and the occurrence of filling defects and voids can be suppressed. As a result, the structural strength of the container can be improved.

[0025] According to the waste carrier according to the present invention, since the waste carrier can be easily slid into the container by a plurality of skids provided below the waste loading part, the loading operation can be easily performed. In addition, since the carrier can be enclosed together with the waste, the recovery process of the carrier is unnecessary, and the construction efficiency can be improved.

[0026] When the waste loading part is composed of a plurality of transverse members that are perpendicular to the plurality of skids in a grid shape, a grid-shaped skeleton structure can be formed by the skids and the transverse members, so that the weight of the waste can be dispersed and supported with a simple structure. In addition, the gap structure between the grids does not prevent the inflow of a filler such as a curing material, and the occurrence of filling defects and voids can be suppressed. As a result, the integration with the filler can be promoted and it can function as an internal reinforcing material, so that the structural strength of the container can be improved.

[0027] In the case of a box with a waste loading section constructed of mesh material at the bottom and side walls, a large amount of waste can be transported while it is contained. Furthermore, the mesh structure allows filling materials such as hardening agents to flow smoothly into the box, suppressing the occurrence of poor filling and voids. As a result, integration with the filling material can be promoted and it can function as an internal reinforcing material, thereby improving the structural strength of the container.

[0028] When angle material with its corners facing downwards is used as a sled, the contact area with the ground can be made linear, reducing frictional resistance. Furthermore, the high cross-sectional rigidity of the angle material allows for stable support of heavy objects. Additionally, because angle material is inexpensive, waste handling equipment can be made inexpensive.

[0029] When the lower corners of the ends of angle materials are cut at an angle, it prevents snagging on steps and other uneven surfaces, allowing for smoother loading and unloading operations.

[0030] When using a waste transport device that includes rotatable rollers for supporting and moving a sled made of angle material, and has circumferentially continuous V-shaped grooves formed on the outer circumference of the rollers where the corners of the angle material engage to guide the sled, the waste transport device can be moved with little force, making it easy to transport the waste into the waste sealing container. In addition, since the corners of the sled are guided by the grooves of the rollers, the waste transport device can be transported stably while suppressing lateral displacement. As a result, even heavy waste transport devices can be transported reliably while reducing the burden on the worker. Furthermore, if the rollers are powered to rotate, transport can be made even simpler.

[0031] If each roller is configured to support one sled, the amount of material required for the rollers can be reduced compared to, for example, using a single cylindrical roller to support all the sleds, resulting in a less expensive device. Furthermore, by providing a roller corresponding to each sled, the load of the waste handling equipment can be distributed and supported across multiple rollers, allowing for stable transport of heavy waste handling equipment.

[Modes for carrying out the invention]

[0033] The embodiments for carrying out the present invention will be described in detail below with reference to the drawings, but the scope of the present invention is not limited to these embodiments.

[0034] Figure 1 shows an exploded perspective view of a waste containment container 1 to which the present invention is applied. The waste containment container 1 is a container (block) formed in a substantially rectangular parallelepiped shape, in which a filling material containing waste and a hardening agent is filled inside, and the waste is sealed by the hardening agent. In this specification, the rectangular parallelepiped is described as being composed of six surfaces: a top surface, a bottom surface, a pair of opposing sides, and opposing front and back surfaces.

[0035] The waste containment container 1 comprises a frame 2 and a pair of end plates 3, 3.

[0036] The frame 2 is a rectangular cylindrical member that constitutes the top surface 11, bottom surface 13, and a pair of side surfaces 12, 12 of the waste sealing container 1, which is roughly rectangular in shape. The pair of side surfaces 12, 12 are formed in a symmetrical shape. The top surface 11 has a filling opening 6 for filling the inside with a packing material. For example, the filling opening 6 is provided in the center of the top surface 11, but the size, shape, and installation position of the opening are arbitrary. A ladder may be provided so that a person can enter the inside from the filling opening 6.

[0037] The pair of side sections 12, 12 have gripping recesses 18, 18 formed on their outer surfaces. Gripping claws, such as those of a lifting clamp, can be attached to the recesses 18, 18.

[0038] The pair of end plates 3, 3 are rectangular plate-shaped members that constitute the front and back portions of the roughly rectangular waste container 1. The pair of end plates 3, 3 are attached to both ends of the frame 2. The end plates 3 are formed in a rectangular shape with the same outer shape as the outer shape of the ends of the frame 2. The frame 2 and the end plates 3 are connected such that their corresponding surfaces are flush. The pair of end plates 3, 3 are constructed by arranging identically shaped members opposite each other.

[0039] The corners of the frame 2 and end plate 3 may be formed at right angles, or they may have chamfered shapes such as C-chamfered shape (corner cut at a 45-degree angle) or R-chamfered shape (corner rounded).

[0040] The frame 2 and end panels 3 are made of concrete. For example, when installing in environments requiring high strength, such as the deep sea, high-strength concrete or ultra-high-strength concrete may be used. By making the frame 2 and end panels 3 pre-fabricated concrete products manufactured in a factory, on-site casting is eliminated.

[0041] As the frame 2 and end plates 3 (waste containment container 1), for example, precast concrete products can be used that are designed and manufactured similarly to prefabricated concrete fire-fighting water tanks or earthquake-resistant water storage tanks in terms of main structure, dimensions, shape, material mix, and reinforcement. For concrete fire-fighting water tanks or earthquake-resistant water storage tanks, the Japan Fire Equipment Safety Center has established certification standards for precast concrete fire-fighting water tanks or precast concrete earthquake-resistant water storage tanks, and they possess sufficient strength and quality. By using such precast concrete products, the waste containment container 1 can also be made to have the same strength and quality as a fire-fighting water tank or earthquake-resistant water storage tank.

[0042] The frame 2 and the end plate 3 are processed so that the contact surfaces (joint surfaces) where they abut each other are flat. Alternatively, the contact surfaces of the frame 2 and the end plate 3 may be formed in a stepped shape (stepped shape) that allows them to fit together. Elastic packing or joint sealant may be applied to the contact surfaces of the frame 2 and the end plate 3.

[0043] A metal expansion anchor 21, having an expandable tip (protruding end), is provided protruding from the frame 2 (either the frame 2 or the end plate 3) at the contact point between the frame 2 and the end plate 3. Since the end plates 3, 3 are joined to both ends of the frame 2, metal expansion anchors 21 are provided protruding from both ends of the frame 2.

[0044] Furthermore, the end plate 3 (the other end plate 3 and the frame 2) is provided with an anchor insertion member 30 having an anchor insertion hole into which a metal expansion anchor 21 is inserted. The load capacity, shape, number, and placement of the metal expansion anchor 21 and the anchor insertion member 30 are arbitrary and can be set appropriately according to the required strength, etc.

[0045] Alternatively, contrary to Figure 1, a metal expansion anchor 21 may be provided protruding from the end plate 3, and an anchor insertion member 30 may be provided on the frame 2.

[0046] Figure 2 shows a partially enlarged cross-sectional view of the frame 2 and end plate 3 in the area where the metal expansion anchor 21 and anchor insertion member 30 are placed. The metal expansion anchor 21 and anchor insertion member 30 function as connecting members for joining the frame 2 and the end plate 3.

[0047] As shown in Figure 2(a), the metal expansion anchor 21 has a split expansion portion 22 at its tip and a threaded portion 23 with a male thread at its rear end (base end). A metal anchor fixing member 25 is embedded in the frame 2 for fixing the metal expansion anchor 21 to the frame 2. The anchor fixing member 25 has a threaded hole 26 with a female thread. The metal expansion anchor 21 is fixed to the frame 2 by screwing the threaded portion 23 into the threaded hole 26.

[0048] The end plate 3 is provided with a metal anchor insertion member 30 having an anchor insertion hole 32. A metal expansion anchor 21 is inserted into the anchor insertion hole 32. The anchor insertion member 30 is provided with a projection 33 at the back of the anchor insertion hole 32 for expanding the expansion portion 22 of the metal expansion anchor 21. The projection 33 is formed, for example, in a conical shape.

[0049] The anchor insertion hole 32 has a first tapered portion 34 formed in a tapered shape that expands toward the back of the hole, allowing it to come into contact with the expanded expansion portion 22. The anchor insertion hole 32 also has a second tapered portion 35 formed in a tapered shape that expands toward the entrance. The second tapered portion 35 on the entrance side is provided to allow the metal expansion anchor 21 to be smoothly inserted into the anchor insertion hole 32.

[0050] In this example, the anchor insertion member 30 is composed of an anchor insertion cylinder 31 and an insertion cylinder bottom 37. The anchor insertion cylinder 31 is formed in a cylindrical shape that forms the outer wall of the anchor insertion hole 32, and a threaded portion 36 with male threads is formed on the outer wall at the back of the cylindrical cylinder (left side in the figure).

[0051] The insertion cylinder bottom 37 has a bottom portion 132 and an annular wall portion 131. The bottom portion 132 is circular in shape and constitutes the deepest part of the anchor insertion hole 32. The bottom portion 132 has a conical projection 33 at its center. The annular wall portion 131 is provided on the outer circumference of the bottom portion 132. The inner wall of the annular wall portion 131 has a screw hole 133 with a female thread that screws into the threaded portion 36 of the anchor insertion cylinder 31. The insertion cylinder bottom 37 (annular wall portion 131) is embedded inside the end plate 3. The end portion 134 of the annular wall portion 131 is located inside the end plate 3 and is prevented from coming loose by abutting against the concrete, which is a component of the end plate 3.

[0052] The anchor insertion member 30 is attached to the end plate 3 by screwing the threaded portion 36 of the anchor insertion cylinder 31 into the threaded hole 133 of the insertion cylinder bottom 37 embedded in the end plate 3.

[0053] Figure 2(b) shows the state in which the frame 2 and the end plate 3 are joined together. By pressing the end plate 3 against the frame 2, the metal expansion anchor 21 is inserted into the anchor insertion hole 32, and the frame 2 and the end plate 3 are joined together in a single touch.

[0054] Specifically, when the metal expansion anchor 21 is inserted into the anchor insertion hole 32, the expansion portion 22 comes into contact with the projection 33 at the back of the hole and is pushed and expanded. The expanded expansion portion 22 comes into contact with the first tapered portion 34, and the wedge action of the projection 33 firmly prevents the metal expansion anchor 21 from coming out of the anchor insertion hole 32. In this way, the expansion of the expansion portion 22 by the projection 33 provides high holding force against axial pull-out force and radial load.

[0055] Figure 3(a) shows a side cross-sectional view of the empty waste containment container 1. The length L from the front to the back of the frame 2 is, for example, 1m to 5m. The height H of the frame 2 is, for example, 1m to 5m. In this example, the case where the length L and height H are approximately the same is shown. The thickness of the end plate 3 is, for example, 0.2m to 0.5m. The capacity of the waste containment container 1 is, for example, 1m³. 3 ~100m 3 That is the case.

[0056] Figure 3(b) shows a side cross-sectional view of the waste containment container 1 in a state where the filler 91 is filled without any voids. The waste containment container 1 is filled with the filler 91, which contains waste and a hardening agent, through the filling port 6. The hardening agent is fluid when filled and hardens after filling. The hardening agent includes, for example, cement and water. Cement hardens by undergoing a chemical reaction (hydration reaction) with water. Concrete can be formed by using cement and water as the hardening agent, along with aggregate (sand, gravel, etc.) and admixtures, and mixing and hardening these. Alternatively, the waste may be used as aggregate for concrete, or as part of the aggregate, and the filler 91 may be formed by mixing cement, water, aggregate and admixtures, pouring the mixture through the filling port 6, compacting it, and hardening it. In the case of large waste, after placing the waste inside the waste containment container 1, a mixture of cement, water, aggregate, and admixture may be poured through the filling port 6, compacted, and hardened to form a concrete filler 91 that surrounds the waste. In this way, the waste is sealed inside the waste containment container 1. The hardening agent is not limited to those described above, and for example, geopolymers made from coal ash or blast furnace slag (a by-product of steelmaking) may be used.

[0057] After the filling material 91 has hardened, the filling port 6 is sealed with a lid 95 as needed. Since cement shrinks when it hardens, the lid 95 can be formed by filling the filling port 6 with non-shrink cement corresponding to the amount of shrinkage and allowing it to harden. Depending on the situation, the lid 95 may be formed with ordinary cement or the like.

[0058] Examples of waste that can be contained in waste containment container 1 include the following: (1) Sediment accumulated in dams, etc. (2) Incinerator ash. (3) Soil removed as a result of decontamination of soil, etc. (4) Various types of waste stored in controlled disposal sites, etc. (5) Large waste items such as used solar panels. (6) Solid waste such as PCB waste and dry cell batteries sealed in containers. (7) Wood, metal, etc. generated from the demolition of buildings. (8) Other types of waste that require landfill disposal. The above-mentioned (1) sand, (2) incinerated ash, and (3) soil can be used as aggregate for concrete that will become the filling material 91.

[0059] The waste containment container 1 enables the installation of various types of waste, such as those described above, in a stable state over a long period of time by integrally sealing them with a hardening agent.

[0060] Figure 4 shows a side cross-sectional view of another waste containment container 1a to which the present invention is applied. This waste containment container 1a has a configuration suitable for placement at the front when multiple waste containment containers 1 described above are arranged in series. Note that components similar to those already described may be denoted by the same or corresponding reference numerals and their descriptions may be omitted.

[0061] The waste containment container 1a comprises a frame 2a and a pair of end plates 3a and 3b. Although not shown in the illustration, the frame 2a and the pair of end plates 3a and 3b are connected by a metal expansion anchor 21 and an anchor insertion member 30, similar to the frame 2 and the pair of end plates 3 and 3 described above. In other words, the waste containment container 1a, similar to the waste containment container 1, has a metal expansion anchor 21 with an expansion portion 22 at its tip protruding from one of the frame 2a and end plates 3a and 3b, and an anchor insertion member 30 having an anchor insertion hole 32 into which the metal expansion anchor 21 is inserted is provided on the other of the frame 2a and end plates 3a and 3b, thus connecting the frame 2a and the pair of end plates 3a and 3b.

[0062] In the waste encapsulation container 1a, one of the pair of end face plates 3a and 3b, i.e., the end face plate 3a, is a protruding end face plate 3a formed in a shape that protrudes above the upper surface portion 11a of the frame body 2a. The protruding end face plate 3a protrudes upward by a length U from the upper surface portion 11a and the other end face plate 3b. The length U is, for example, 0.1 m to 0.3 m. The frame body 2a and one end face plate 3a are connected such that the corresponding surfaces other than the upper surface portion 11a are flush. The other end face plate 3b has the same outer shape as the aforementioned end face plate 3. The frame body 2a and the other end face plate 3b are connected such that the corresponding surfaces are flush.

[0063] By providing the protruding end face plate 3a, when stacking other waste encapsulation containers 1 and 1a on the upper part of the waste encapsulation container 1a, even if the upper container is displaced toward the protruding end face plate 3a side, the protruding end face plate 3a abuts to suppress the displacement. That is, the protruding end face plate 3a functions as a stopper.

[0064] The frame body 2a of the waste encapsulation container 1a provided with the protruding end face plate 3a is preferably formed to have a longer length (cylinder length) from the front side to the back side than the frame body 2 of the waste encapsulation container 1 not provided with the protruding end face plate 3a. In this example, an example is shown where the length La from the front side to the back side of the frame body 2a is set to La = 1.5L with respect to the length (cylinder length) L (see FIG. 3) from the front side to the back side of the frame body 2. For example, a range of L < La ≤ 2L is preferable. Note that the length La of the frame body 2a is arbitrary, and for example, La = L may be set.

[0065] By forming the waste encapsulation container 1a longer than the waste encapsulation container 1, the waste encapsulation container 1 can be stably stacked on the waste encapsulation container 1a at the uppermost part where the waste encapsulation containers 1 and 1a are stacked.

[0066] The height Ha of the frame body 2a is the same as the height H (see FIG. 3) of the frame body 2 of the waste encapsulation container 1.

[0067] A filling port 6a is provided on the upper surface 11a of the frame 2a for filling with a material containing waste and a hardening agent. The size, shape, and position of the filling port 6a are arbitrary. In this example, the size and shape of the filling port 6a are the same as those of the filling port 6, and the distance (positional relationship) from the protruding end plate 3a to the filling port 6a is set to be the same as the distance (positional relationship) from the end plate 3 to the filling port 6 in the waste sealing container 1. This allows the frame 2a to be manufactured by sharing a part of the molding die for the frame 2, thereby reducing manufacturing costs. The filling port 6a may also be provided in the center of the upper surface 11a.

[0068] Furthermore, it is preferable that one end of one bolt 41a is fixed to one of the pair of end plates 3a, 3b (the protruding end plate 3a in this example), one end of the other bolt 41b is fixed to the other end plate 3b, and the other end of the bolt 41a and the other end of the bolt 41b are connected by a turnbuckle 45.

[0069] One bolt 41a and the other bolt 41b are arranged in the same straight line. One end of one bolt 41a is fixed to the center of the inner surface of one end plate 3a (protruding end plate 3a) by a known fastener 42a. One end of the other bolt 41b is fixed to the center of the inner surface of the other end plate 3b by a known fastener 42b. Note that the fasteners 42a and 42b may be formed by bending one end of bolts 41a and 41b.

[0070] The turnbuckle 45 has one threaded portion 46a that screws onto the other end of one bolt 41a, another threaded portion 46b that screws onto the other end of the other bolt 41b, and two connecting members 48, 48 that connect the one threaded portion 46a and the other threaded portion 46b.

[0071] One threaded portion 46a and the other threaded portion 46b have opposite threads (right-hand thread and left-hand thread). Therefore, by rotating the turnbuckle 45, the bolts 41a and 41b are pulled closer or further apart, thereby increasing or decreasing the tension between the bolts 41a and 41b.

[0072] By rotating the turnbuckle 45 to increase the tension between bolts 41a and 41b, tension is generated that pulls the pair of end plates 3a and 3b together. Therefore, even if a large load is placed on the end plates 3a and 3b due to the weight of the contents contained in the waste sealing container 1a, it is possible to prevent the end plates 3a and 3b from detaching from the frame 2a or being damaged.

[0073] In this example, a single structure consisting of a turnbuckle 45 and bolts 41a and 41b is shown in the waste sealing container 1a, but multiple structures consisting of turnbuckles 45 and bolts 41a and 41b may be provided. The number of structures provided should be set appropriately according to the required strength.

[0074] Furthermore, the maximum distance A between the inner sides of the two connecting members 48, 48 is preferably as large as possible, and is preferably at least 100 mm. By ensuring a sufficient maximum distance A, the filler material 91 such as cement flows smoothly between the connecting members 48, 48, making it less likely for voids to form inside. As a result, the crushing strength can be improved.

[0075] Such a structure consisting of a turnbuckle 45 and bolts 41a and 41b can also be applied to the waste containment container 1 described above.

[0076] Figure 5 shows a schematic diagram of the usage state of waste containment container 1 and waste containment container 1a. In this example, an example of reclaiming land from land 115 to the sea 112 is shown. On the seabed 111, waste containment containers 1, 1, ..., 1 filled with packing material are placed sequentially from the bottom and stacked. A waste containment container 1a is placed at the offshore end of each row. Since waste containment container 1a is longer and heavier than a normal waste containment container 1, it can improve stability at the end of the row. In addition, since waste containment container 1a is equipped with the aforementioned protruding end plate 3a (see Figure 4), it can prevent waste containment containers 1 and 1a stacked on the upper layer from moving towards the offshore side. This prevents detachment or collapse at the end of the row.

[0077] As for the top tier, since no containers are stacked on top of it, the waste containment container 1 may be placed at the tip on the offshore side.

[0078] If it is necessary to adjust the length of the rows, waste containers 1, 1a with frames 2, 2a of a different length from the other containers can be manufactured and used as part of the rows. Also, if there are gaps between waste containers 1(1a), the gaps may be filled with a filler material such as a non-shrink cement-based filler (grout). Furthermore, the overall strength may be increased by surrounding multiple waste containers 1(1a) with a high-strength fabric-like material. An example of a high-strength fabric-like material is Bash Fiber (registered trademark) manufactured by Shin Nippon Textile Co., Ltd.

[0079] The waste containment containers 1 and 1a can be applied not only to sea areas but also to ponds, rivers, land, and other areas targeted for landfill. For example, the waste containment containers 1 and 1a may be used as revetment material, repair material for collapsed embankments, or landfill material for collapsed slopes, etc.

[0080] As described above, the waste containment containers 1 and 1a according to the present invention allow for secure connection of the frame bodies 2 and 2a and the end plates 3, 3a and 3b by simply pushing them together, without the need for welding or on-site casting, thus simplifying the assembly process. Furthermore, the waste containment containers 1 and 1a allow for landfilling while the waste is sealed together with the hardening material inside. Additionally, the waste containment container 1a ensures stability at the end of the rows when stacked, contributing to improved safety and construction efficiency in large-scale landfill construction. Therefore, the present invention provides a landfill structure that not only offers excellent workability in assembly but also achieves both effective utilization of waste and improved constructability.

[0081] Regarding the method of sealing waste into the waste sealing containers 1, 1a, the waste and hardening agent may be poured together through the filling ports 6, 6a to harden (solidify) the hardening agent, or the waste may be placed inside first, and then the hardening agent may be poured in through the filling ports 6, 6a to harden it. The waste may be brought in through the filling port 6, or it may be brought into the frame 2, 2a before the end plates 3 (3a, 3b) are attached. After bringing in the waste, the container can be closed by attaching the end plates 3 (3a, 3b) to the frame 2, 2a.

[0082] Figure 6 shows a waste handling device 51 to which the present invention is applied. The waste handling device 51 is used to transport waste into the waste sealing containers 1, 1a, and is an example of a handling device that is sealed inside the container together with the waste. The waste handling device 51 has multiple long sleds 52 arranged parallel to each other on the lower side of the waste loading section 53 on which the waste is loaded. In this example, five sleds 52 are provided, but the number can be appropriately set according to the weight of the waste to be loaded, etc.

[0083] The sled 52 is constructed, for example, from angle steel. Angle steel is a structural metal material with an L-shaped cross-section, also known as angle steel. Angle steel is suitable for use because it is relatively inexpensive and readily available. The sled 52 is attached to the underside of the waste loading section 53 with the L-shaped corner of the angle steel facing downwards. There are no limitations on the shape and material of the sled 52; for example, it may be made of a flat plate-like member such as a skate blade, or a round pipe.

[0084] The waste loading section 53 is constructed by arranging multiple transverse members 54 perpendicular to multiple long sleds 52 in a grid pattern. Spacing is provided between the transverse members 54 to facilitate the flow of cement and other materials downwards. One example of a transverse member 54 is an angle iron. Angle iron is suitable for use because it is relatively inexpensive and readily available. There are no limitations on the shape or material of the transverse members 54; for example, they may be made of plate material, pipe material, etc.

[0085] Figure 7 shows a magnified side view of a portion of the tip of the sled 52. The angle material that makes up the sled 52 is formed with the lower corner of the end 56 cut at an angle. Both ends 56 of the sled 52 are formed in a similar shape. This shape improves sliding ability and allows for smoother loading operations.

[0086] Figure 8 shows another waste handling device 51a to which the present invention is applied. The waste handling device 51a is an example of a handling device used to transport waste into the waste sealing containers 1, 1a and is sealed together with the waste. Components similar to those already described may be denoted by the same or corresponding reference numerals and their description may be omitted.

[0087] The waste handling device 51a is equipped with a waste loading section 61 for loading waste. Below the waste loading section 61, several long sleds 52 are provided parallel to each other. This example shows the waste handling device 51 attached to the bottom of the waste loading section 61. Alternatively, the sleds 52 may be directly attached to the bottom of the waste loading section 61. If the sleds 52 are directly attached to the bottom of the waste loading section 61, the height of the waste handling device can be reduced by eliminating the need for the crossing member 54. Alternatively, if the sleds 52 are directly attached to the bottom of the waste loading section 61, the height of the waste handling device can be increased by eliminating the need for the crossing member 54, thereby increasing the capacity of the waste loading section 61.

[0088] The waste loading section 61 is a box with an open top. The waste loading section 61 has a skeleton formed by 12 edge members 62 arranged on each side of a rectangular parallelepiped shape, for example. The edge members 62 are formed from angle iron, for example. In areas where strength is required, angle iron is appropriately combined to provide strength. There are no limitations on the shape, material, etc. of the edge members 62; for example, they may be formed from plate material, pipe material, etc.

[0089] The waste loading section 61 has metal mesh members 63 stretched across the bottom and all four side walls of the box. Each mesh member 63 is formed in a rectangular shape and stretched between the edge members 62 on each surface. In the figure, only a portion of the mesh member 63 is shown on each surface, and the entire mesh member 63 is not shown.

[0090] By constructing the bottom and all four side walls of the waste loading section 61 with mesh members 63, cement and the like can flow smoothly into the interior and lower part of the waste loading section 61 through the mesh members 63, promoting integration with the filler material. It is preferable that the mesh size of the mesh members 63 be such that cement and the like can easily flow through.

[0091] Figure 9 shows an explanatory diagram illustrating how to use the waste handling device 51a. The figure shows a side cross-sectional view of the waste sealing container 1 in a state where one end of the frame 2 (the right end of the frame 2 in the figure) is not attached to one end, and one end of the frame 2 is open, as well as a side view of the waste handling device 51a.

[0092] Figure 9(a) shows the waste container 1 before the waste handling device 51a is brought in. The waste handling device 51a is placed on a transport platform 201 which is at the same height as the inner surface of the bottom portion 13 of the frame 2. The transport platform 201 carries the waste handling device 51a to one end of the frame 2. Waste is placed inside the waste handling device 51a, although this is not shown.

[0093] Before loading the waste handling device 51a, the inner surface of the bottom portion 13 of the frame 2 is cooled. One method of cooling is to spray a cooling medium such as dry ice or liquid nitrogen. This causes moisture in the air to freeze and form an ice film 72 on the inner surface. Alternatively, water may be sprayed and then cooled to form the ice film 72. An ice film 72 may also be formed on the upper surface of the transport table 201.

[0094] The waste transporter 51a is equipped with a sled 52. Therefore, when the waste transporter 51a is pushed towards the bottom surface 13, the waste transporter 51a slides on the ice film 72 and is smoothly transported into the frame 2. The waste transporter 51a is positioned in a predetermined location within the frame 2 by coming into contact with a stopper 71 provided on the inner surface of the bottom surface 13 and stopping. The stopper 71 is pre-installed at the position where the sled 52 will come into contact.

[0095] Although not shown in the diagram, after the waste handling device 51a is brought into the frame 2, the end plate 3 is attached to one end of the frame 2, and cement or the like is injected through the filling port 6. After the cement or the like hardens, non-shrink cement or the like is filled into the filling port 6 to form the lid 95 (see Figure 2).

[0096] Although the loading of the waste loading device 51a has been illustrated and explained, the waste loading device 51 can also be loaded into the frame 2 in the same manner. In a frame 2a equipped with a turnbuckle 45, a low-height waste loading device 51 can be suitably used. Alternatively, the turnbuckle 45 may be attached after loading the waste loading devices 51 and 51a into the frame 2a.

[0097] Thus, by using the waste handling devices 51 and 51a according to the present invention, waste can be efficiently and safely transported into the waste sealing container 1(1a), and integration with the hardening material can be promoted.

[0098] Furthermore, the waste transport devices 51 and 51a may be equipped with wheels instead of the sled 52.

[0099] Next, we will describe a waste handling device moving device 81 that makes it easier to transport the waste handling device 51 (51a) to the bottom surface 13 of the waste sealing container 1 (1a).

[0100] Figures 10 and 11 show explanatory diagrams of a waste handling device moving device 81 for transporting the waste handling device 51 (51a) to the bottom surface 13 of the waste sealing container 1 (1a). Figure 10 shows the state before the waste handling device 51 (51a) is transported to the bottom surface 13. In this figure, one end plate 3 is not attached to one end of the frame 2 (the right end of the frame 2 in the figure), and one end of the frame 2 is open. The figure also shows a side cross-sectional view of the bottom surface 13 with some parts enlarged, and a side view of the waste handling device 51 with some parts enlarged.

[0101] The waste handling equipment moving device 81 is a rotary conveyor (roller conveyor). As mentioned above, the waste handling equipment 51 is equipped with a plurality of sleds 52 at its bottom. The sleds 52 are made of, for example, angle material and are used to support and move the waste handling equipment 51. The waste handling equipment moving device 81 is equipped with a plurality of rotatable rollers 82 on which the sleds 52 are placed and moved. The rollers 82 are rotatably supported by shaft members 83 and rotate in place. The waste handling equipment moving device 81 transports the waste handling equipment 51 to one end of the frame 2.

[0102] Figure 11 shows a front view of the waste handling equipment moving device 81. The figure also shows the waste handling equipment 51 above the waste handling equipment moving device 81. Multiple rollers 82 arranged in a horizontal row are positioned at the same number of locations as the number of sleds 52 of the waste handling equipment 51, so as to support the multiple sleds 52 of the waste handling equipment 51. Multiple such horizontal rows of rollers 82 are arranged in the front-to-back direction (from the front to the back) at predetermined intervals (see Figure 10).

[0103] Each roller 82 is configured to support one sled 52. In other words, one sled 52 is placed on each roller 82. This configuration reduces the amount of roller material required compared to, for example, using a single cylindrical roller to support all the sleds 52, thus allowing for a less expensive device to be constructed. Furthermore, by providing a roller 82 corresponding to each sled 52, the load of the waste transport device 51 can be distributed and supported across multiple rollers 82, enabling stable transport of the heavy waste transport device 51. Additionally, by making the position of the rollers 82 movable, or by making it possible to add or remove rollers 82, it becomes possible to accommodate waste transport devices 51 with different spacings and numbers of sleds 52.

[0104] A circumferentially continuous V-shaped (inverted V-shaped) recess 85 is formed on the outer circumference of the roller 82, which engages with the corners of the angle material constituting the sled 52 to guide the sled 52. The recess 85 is formed, for example, in the center of the outer circumference of the roller 82. The angle of the V-shape of the recess 85 is formed to correspond to the angle of the corner of the sled 52 (for example, 90°) (for example, 90° or a slightly larger angle) so that the corner of the sled 52, which is made of angle material, fits into it.

[0105] By providing the roller 82 with a V-shaped recess 85 in this way, the corner of the sled 52 engages with (enters into) the recess 85 and is guided as it moves, so that the waste handling device 51 moves in a straight line without shifting in the left or right direction. In other words, the recess 85 functions as a guide groove. Therefore, the waste handling device 51 can be carried into the waste sealing container 1 (1a) in a stable position.

[0106] If necessary, a single cylindrical roller having an axial length capable of supporting all the sleds 52 may be used, and a plurality of recesses 85 corresponding to the number of sleds 52 may be provided on the outer circumference of this roller.

[0107] The rollers 82 are, for example, rotatably supported by a rod-shaped shaft member 83. Each roller 82 may be supported by an independent shaft member 83. The shaft members 83 are attached to a device body (not shown). The rollers 82 have bearing members, such as bearings, between them and the shaft members 83, and are rotatably supported. As a result, the rollers 82 rotate smoothly, and the waste handling device 51 placed on the rollers 82 can be smoothly moved by pushing it by hand. This allows the waste handling device 51 to be easily loaded into the bottom surface 13 of the frame 2. It is preferable to form an ice film 72 on the inner surface of the bottom surface 13 as described above before loading.

[0108] Furthermore, the waste handling device moving device 81 may have a power source to rotate the rollers 82. If it has a power source, the waste handling device 51 can be moved even more easily without having to push it by hand. Also, although Figure 11 shows an example in which the same number of rollers 82 as the number of sleds 52 (5 in the example shown in the figure) are arranged in a horizontal row, fewer rollers 82 than the number of sleds 52 may be arranged as long as there are no load-bearing capacity issues. For example, a configuration with a total of 3 rollers 82, one on each side and one in the center, may be used.

[0109] Thus, by using the waste handling device moving device 81 according to the present invention, the waste handling device 51 (51a) can be easily transported into the waste sealing container 1 (1a).

[0110] Next, an example of how to use the waste sealing container 1(1a) to which the present invention is applied will be described. Figure 12 is a front view showing the waste containment container 1 to which the present invention is applied in use. As shown in the figure, the waste handling device 51a (see Figure 8) is housed inside the waste containment container 1, and multiple flexible container bags 301 are housed in the waste loading section 61 of the waste handling device 51a. The flexible container bags 301 are bags made of chemical fibers and can store any waste, such as soil, sand, or ash.

[0111] As an example, the flexible container bag 301 contains contaminated soil generated from decontamination work in Fukushima Prefecture as waste. A mixture of cement, water, aggregate, etc. (not shown) is poured into the waste sealing container 1, and as this mixture hardens, the waste transport device 51a and the flexible container bag 301 are sealed in the concrete. In this way, the waste sealing container 1 of the present invention can properly seal waste such as contaminated soil generated from decontamination work.

[0112] Next, we will describe an example of another way to use the waste sealing container 1(1a) to which the present invention is applied. Figure 13 is a schematic diagram showing a waste containment container 1 installed as a protective material for a submarine cable 401 laid on the seabed 411. The waste containment container 1 contains waste, and as shown in Figure 12, for example, the waste transport equipment 51a and the flexible container bag 301 are sealed with concrete. The flexible container bag 301 contains waste such as contaminated soil.

[0113] By placing waste containment containers 1 on both sides and above the submarine cable 401 and surrounding the submarine cable 401, the submarine cable 401 can be protected from external mechanical forces, such as the dragging of a ship's anchor. Since the submarine cable 401 is long, and there is a large amount of contaminated soil generated by the decontamination work in Fukushima Prefecture, the contaminated soil can be effectively utilized by sealing it in the waste containment containers 1.

[0114] The objects to be protected are not particularly limited and may be various structures, equipment, or components. Examples of such objects to be protected include infrastructure equipment, piping components, cable components, or installation components installed underground or underwater. Specifically, these include submarine cables, submarine pipelines, underwater piping, communication equipment, power equipment, environmental measurement equipment, or various pipes and cables installed underground. By placing the waste containment container 1(1a) around these objects to be protected, the objects can be strongly protected from external mechanical forces. [Explanation of Symbols]
