  However, such a hardly water-permeable barrier needs to be able to be constructed efficiently.

  This invention is made | formed in view of the above, Comprising: It aims at providing the compacting machine which enables efficient compacting construction.

In order to solve the above-described problems and achieve the object, the present invention includes a plurality of rolling elements that are drawn downward to compact the soil material in a direction intersecting the construction direction, and each rolling element is drawn out at different timings. Thus, the compacting machine compacts the soil material, and sets the length of the rolling element in the feeding direction to be larger than the feeding stroke of the rolling element, and the rolling surface of the rolling element is from the front in the construction direction. It has a side edge that is inclined so as to protrude gradually toward the rear in the construction direction .

The compactor according to the present invention comprises a plurality of compacted bodies in a direction intersecting the construction direction, and by rolling out the compacted bodies at different timings , the soil material is compacted, so the compacted work can be efficiently performed. is there. Further, since the length of the rolling element in the feeding direction is set larger than the feeding stroke of the rolling element, one of the adjacent rolling elements is located at the top dead center and the other is located at the bottom dead center. However, adjacent rolling elements do not overlap, and the other rolling element is not damaged by one rolling element.

The rolling surface of the rolling element has a side edge that is inclined so as to protrude gradually from the front in the construction direction toward the rear in the construction direction, so that the rolling is performed even if there is a gap between adjacent rolling elements. There are no streaks on the construction surface.

  Since a shift device that shifts multiple rolling elements in a direction that intersects the construction direction is provided, if the width of the construction surface is narrower than the width of the multiple rolling elements, or the construction direction is different from the running direction of the compactor Even if it is a case, rolling compaction construction is possible without correcting the track.

  Since it has a leveling device that spreads soil material forward in the construction direction of multiple rolling elements, the compactor presses the soil material in front of the construction direction and leveles soil material in the rear of the construction direction. It can be rolled.

  Below, the compaction machine concerning an embodiment of the invention is explained in detail based on a drawing. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
1 is a front view of a compactor according to Embodiment 1 of the present invention, FIG. 2 is a side view of the compactor shown in FIG. 1, and FIG. 3 is a conceptual diagram showing the configuration of the compactor shown in FIG. FIG. 4 is a conceptual diagram showing an operating state of the rolling compaction drive device shown in FIG.

  As shown in FIGS. 1 and 2, the compactor 1 according to the first embodiment includes a traveling device 2. The traveling device 2 of the compactor according to the first embodiment is a crawler traveling device, and can travel in any direction by an operation from a driver's seat 3 provided on the upper portion of the traveling device 2. The traveling device 2 is not limited to the crawler traveling device, and may be a different type of traveling device, for example, a wheel traveling device.

  Further, a leveling device 4 wider than the traveling device 2 is provided behind the traveling device 2. The leveling device 4 is a device for leveling the soil material ahead of the compactor 1 in the construction direction so as to have a uniform height, and the soil discharge plate 41 is set to an arbitrary height by an operation from the driver's seat 3. It is possible. Therefore, the leveling device 4 can spread and level the soil material at an arbitrary height. The leveling device 4 may be any material as long as it spreads and leveles the soil material in the forward direction of the compactor 1, and is provided in front of the traveling device 2 as shown by the two-dot chain line in FIGS. Also good. As described above, the leveling device 4 provided in front of the traveling device 2 is attached to, for example, a beam 61 described later, and the hydraulic cylinder 42 is operated by the operation from the driver's seat 3 so that the earth discharging plate 43 can be arbitrarily set. It is possible to set to the height of.

  A lifting device 5 is provided in front of the driver's seat 3. A rolling device 6 wider than the traveling device 2 is attached to the lifting device 5. The elevating device 5 can elevate and lower the compaction device 6, raises the compaction device 6 when moving the compaction device 1 to the construction site, and places the compaction device 6 in a predetermined position when operating the compaction device 1. For example, it can be lowered to a position close to the soil material as long as the rolling device 6 does not attract the soil material.

  As shown in FIG. 3A, it is preferable to provide a shift device (not shown) between the lifting device 5 and the rolling device 6. The shift device can move the compaction device 6 in a direction intersecting the construction direction (left and right direction in FIG. 3A), and the compaction device 6 can be moved in a direction intersecting the construction direction by the driving force of the hydraulic cylinder 8 or the like. Shift is possible.

  As illustrated in FIG. 3A, the compaction device 6 includes a beam 61 and a plurality of compaction units 62. The beam 61 is a plate-like body, and is attached to the lifting / lowering device 5 or the shift device in such a manner that its longitudinal direction is orthogonal to the construction direction of the compactor 1. The plurality of rolling unit 62 is attached in the longitudinal direction of the beam 61, and the rolling unit 62 is arranged in a manner orthogonal to the construction direction of the rolling machine 1. Therefore, when the beam 61 moves up and down, all the rolling units 62 move up and down.

  Each rolling unit 62 includes a drive unit 621 and a rolling element 622. The drive unit 621 is a part that draws out the rolling element 622 downward, and the rolling element 622 is a part that rolls the soil material. The rolling element 622 has a rectangular parallelepiped shape, and the surface (hereinafter referred to as “rolling surface 622a”) for rolling the earth material has a rectangular shape (the rolling surface according to the present embodiment is shown in FIG. 3-2). Square shape).

  As shown in FIG. 4, the drive unit 621 can be driven independently, and is configured such that each rolling element rolls the soil material at different timings. Therefore, the rolling material unit 62 does not roll the soil material at different timings, and all the rolling unit 62 does not simultaneously roll. Further, the length L in the feeding direction of the rolling element 622 is formed larger than the feeding stroke Ls of the rolling element 622, and one rolling element 622 of the adjacent rolling unit 62 is located at the top dead center. Even if the rolling element 622 of the other rolling unit 62 is located at the bottom dead center, the rolling elements 622 do not overlap.

  As shown in FIG. 5, the compacting machine 1 configured in this way can be compacted in cooperation with the brewing machine 7. The brewing machine 7 used here is a machine for rolling out the soil material on the construction surface, and has a traveling device 71, a hopper 72 for storing the soil material, and a conveyor 73 for sequentially rolling out the soil material from the hopper 72. ing. The soil material squeezed out from the brewing machine 7 is leveled at a predetermined height by the leveling device 4 of the compactor 1, and then rolled by the compacting unit 6 of the compactor 1. Therefore, as shown in FIG. 6, rolling work can be performed even in a narrow portion surrounded by the structure S. Further, even when the width of the compacting device 6 is wider than the construction width, or even when the construction direction is different from the traveling direction of the compacting device 1, the shift device shifts the compacting device 6 so that the compacting press 1 The rolling direction is applied without correcting the running direction of the track.

  Moreover, for example, as shown in FIG. 7, the construction can also be performed in a low-level radioactive waste embedding disposal facility 100. The buried disposal facility 100 has an underground hollow casing 102 installed in an excavated underground mine 101, and a radioactive waste storage casing 103 in which low-level radioactive waste is hermetically stored can be embedded. is there. Then, after housing the radioactive waste storage housing 103, a clay-based water shielding material is rolled around the periphery, that is, between the radioactive waste storage housing 103 and the underground cavity housing 102, so The sexual barrier 104 is constructed. As a result, the radioactive waste storage casing 103 that has been buried is surrounded by a high-density clay-based water shielding material. The clay-based water shielding material is, for example, bentonite, and after containing the radioactive waste storage casing 103, the bentonite is sequentially sprinkled from the above-described brewing machine 7, while the compactor 1 according to the first embodiment is used. After the bentonite is leveled at a predetermined height, the bentonite is pressed at a high density.

  According to the above-described rolling compactor 1 according to the first embodiment, since a plurality of the rolling compaction units 62 are provided in a direction intersecting with the construction direction, a strip-shaped compacting construction wider than the traveling device 2 is possible. In addition, since the rolling unit 62 is configured to perform rolling at different timings, the vibration shock accompanying the rolling is dispersed and efficient rolling work is possible.

  Further, since the length L in the feeding direction of the rolling element 622 is formed larger than the feeding stroke Ls of the rolling element 622, one rolling element 622 of the adjacent rolling unit 62 is located at the top dead center. Even if the other rolling element 622 is located at the bottom dead center, the rolling elements 622 do not overlap. Therefore, the one rolling element 622 does not damage the other rolling element 622, and efficient rolling work can be performed.

  Further, when a shift device is provided between the lifting device 5 and the compaction device 6, the width of the compaction device 6 is narrower than the construction width, or the construction direction is different from the traveling direction of the compactor 1. Even so, when the shift device shifts the compaction device 6, the compaction work can be performed without correcting the track of the traveling direction of the compactor 1.

  Instead of the above-described rolling element 622, as shown in FIG. 8, the rolling surface 622a 'may be formed of a cube formed so as to extend gradually from the front in the construction direction to the rear in the construction direction. Such a rolling element 622 ′ includes a cube formed such that the rolling surface 622a ′ is a parallelogram (including a rhombus), or a rolling surface 622a ′ includes a trapezoid (a right-angled trapezoid having two right angles). ) To form a cube. In the example shown in FIG. 8, a plurality of rolling elements 622 ′ having the same shape formed so that the rolling surface 622a ′ has a rhombus shape is disposed in the center, while the rolling surface formed so that the rolling surface 622a ′ has a right trapezoid shape. A pressure body 622 'is disposed on both sides.

  Therefore, when rolling is performed using the rolling element 622 'formed in this manner, a streak-like unworked portion does not occur on the work surface. This is because the compaction machine 1 rolls while moving in the construction direction, and the unrolled portion generated by the gap formed between the compacted bodies 622 'is gradually rolled.

A main body consists of a table lift which can raise / lower the table 12a, and can raise / lower the table 12a arbitrarily. The table 12a has a compaction device 14 and a weight 15 attached. When the compaction machine 11 is moved, the compaction device 14 is raised, and when the compaction machine 11 is operated, the compaction device 14 is lowered. It is possible.

  The compaction device 14 includes a beam 141 and a plurality of compaction units 142. The beam 141 is a plate-like body, and is attached to the table 12a in such a manner that its longitudinal direction intersects the construction direction. The plurality of compaction units 142 are attached in the longitudinal direction of the beam 141, and the compaction units 142 are arranged in a manner orthogonal to the construction direction of the compactor 11. Therefore, when the beam 141 moves up and down, all the rolling units 142 move up and down.

  Each rolling unit 142 includes a driving unit 1421 and a rolling body 1422. The drive unit 1421 is a part that draws out the rolling element 1422 downward, and the rolling element 1422 is a part that rolls the soil material. The rolling element 1422 has a cubic shape, and the rolling surface is formed in an arbitrary shape such as a rectangular shape, a parallelogram shape, a rhombus shape, or a right-angled trapezoid shape.

  The drive unit 1421 can be driven independently, and is configured to roll the soil material at different timings. Therefore, the rolling unit 142 alternately rolls the soil material, and all the rolling units 142 do not roll simultaneously. Further, the length in the feeding direction of the rolling element 1422 is formed to be larger than the feeding stroke of the rolling element 1422, and one rolling element 1422 of the adjacent rolling unit 142 is located at the top dead center, and the other Even if the rolling element 1422 of the rolling unit 142 is located at the bottom dead center, the rolling elements 1422 do not overlap.

  The weight 15 is a weight for balancing the impact of the rolling device 14 and can prevent the rolling device 11 from falling down.

  According to the above-described rolling compactor 11 according to the second embodiment, since a plurality of the compacting units 142 are provided in the direction intersecting the construction direction, a wide belt-shaped compaction construction is possible. In addition, since the rolling unit 142 is configured to perform rolling at different timings, the vibration shock accompanying the rolling is dispersed and efficient rolling work can be performed.

  Further, since the length in the feeding direction of the rolling element 1422 is formed larger than the feeding stroke of the rolling element 1422, one rolling element 1422 of the adjacent rolling unit 142 is located at the top dead center, and the other Even when the rolling element 1422 of the rolling unit 142 is located at the bottom dead center, the rolling elements 1422 do not overlap. Therefore, the one rolling element 1422 does not damage the other rolling element 1422, and efficient rolling work can be performed.
