Description

  The present invention relates to a slope compaction device.

  In a highway, a railway, a dike, a housing development site, etc., a flat ground surface may be formed by building a banking structure by raising earth and sand on a low ground or slope.

  When the embankment structure is compacted, if the slope is compacted and the top surface is compacted separately, the slope may be deformed by compacting the top surface.

Therefore, when compacting an embankment structure, it is desirable to compact the upper surface and the slope at the same time.
For example, Patent Document 1 discloses a rolling element that is detachable from a backhoe (base machine). When this rolling element is attached to the backhoe and the rolling element is pressed against the shoulder by the hydraulic pressure of the backhoe, the upper surface and the slope of the embankment structure can be simultaneously compacted.

In order to be possible, it is characterized in that it has a trapezoidal shape in which the width on the side of the heel is smaller than the width on the side of the upper surface shaping portion.

  According to such a compacting device, since the slope shaping part is trapezoidal, it is possible to roll along the break point of the corner of the slope. Therefore, the embankment structure can be compacted easily and evenly.

  In addition, if the upper surface shaping part has a trapezoidal shape in which the width on the side of the slope shaping part is smaller than the width on the opposite side of the slope, for the embankment structure having a fold point, together with the slope The upper surface can be uniformly compacted.

The slope shaping unit may be provided with slats on the left and right sides, and may be provided with a slope tail shaping plate at the edge of the slope side.
As the slats, it is desirable that the slats come into contact with the other slope when the slope shaping part is pressed against one of the two slopes forming the entering corner.
Further, as the slope bottom shaping plate, it is desirable that the slope bottom plate comes into contact with a plane connected to the slope when the slope shaping portion is pressed against the slope.

  If the compaction device has an angle sensor attached to the boom of the base machine and a GPS antenna attached to the base machine, the compaction device can be used while confirming the position of the compaction body, base machine, etc. Work can be performed.

Next, a compacting method using the compacting device 1 will be described.
First, the base machine 10 is run on the embankment material spread using a heavy machine such as a bulldozer, so that it is in a predetermined position (for example, a position where the distance from the shoulder to the running means is 2.9 m). A compaction device 1 is arranged.

At this time, the base machine 10 performs position management via the GPS antenna (see FIG. 5).
A wireless LAN is installed in the factory, and the construction status is monitored and managed in real time by data communication of the arrangement and work status of the base machine 10.

  Next, the rolling element 20 is grounded to the shoulder. At this time, the rolling element 20 is disposed while adjusting the angle with an inclinometer so that the separation distance from the traveling means of the base machine has a predetermined size. Further, according to the vector sensor mounted on the rolling element 20, the grounding force is grounded so that the vector direction of the compaction force is a predetermined direction.

Next, the rolling surface 20 simultaneously rolls the slope and the upper surface for a certain time (for example, 30 seconds). At this time, only the own weight of the rolling element 20 is applied to the slope and the upper surface. That is, the pushing force using the boom 11 is not applied to the slope and the upper surface. By doing so, the whole embankment structure B is compacted under the same conditions.
In addition, each data such as compaction time and pressing energy is transmitted by wireless LAN, and each data is stored.

When the rolling by the rolling element 20 is completed, the rolling element 20 is moved away from the shoulder and the base machine 10 is run to place the compacting device 1 at the next position. The next compaction position may be wrapped to the compaction position immediately before the end.
By repeating the above operations, the whole embankment structure B is uniformly compacted.

As shown in (b) to (e) of FIG. 6, when the embankment structure B includes a recess _BD for installing a seam stop plate as shown in (a) of FIG. 6. , Evenly corner the corners.

  That is, as shown in FIG. 6B, first, the slope shaping unit 21 is pressed against one of the two slopes forming the corners, and the slat 23 is pushed to the other slope. Tighten it while pressing against the surface.

  Next, after the compaction device 1 is moved, as shown in FIG. 6C, the slope shaping unit 21 is pressed against the other slope and the slat 23 is pushed against the one slope. Clamp in contact.

As shown in (d) and (e) of FIG. 6, the same operation is repeated to uniformly compact the recesses _BD of the embankment structure B.

  Next, a construction management method will be described with reference to FIG.

First, based on the design data (for example, the planned height or extension distance of the embankment structure B), three-dimensional data of each piece of information on the construction range is created (S1).
Next, the created three-dimensional data is input to the computer online using a wireless LAN or offline using a USB memory or the like (S2).

Subsequently, the embankment material is embanked and shaped at the end shoulder of the embankment structure (S3).
At this time, compaction is performed for about 30 seconds at one place within one block length (for example, 15 m). The compaction is performed while holding adjacent compaction locations and a lap portion (for example, about 10 cm). A monitor connected to the computer via a wireless LAN is installed in the driver's seat of the base machine.

  The construction by the compacting device 1 is performed by specifying the position of the rolling element 20 by the GPS antennas 30 and 30 and the angle sensor 31 attached to the base machine 10, and further acquiring the ON / OFF signal of the rolling element 20 and tightening. The setting time is controlled by a computer.

The compaction time by the rolling element 20 for each construction location is recorded in the computer (S4).
The cumulative compaction time is calculated for each construction location, and when the cumulative compaction time reaches the specified time, compaction of the construction location is completed. At this time, the compacting completion time is recorded in the computer (S5).
The compaction state based on the compaction time and the position of the compaction device 1 can be confirmed by the operator by displaying it on the driver's seat monitor. The monitor shows the positional relationship between the embankment structure B and the base machine 10, and the accumulated compaction time for each location of the embankment structure B is displayed in different colors so that the operator can check the construction status at a glance. It can be so.

  When the construction is completed, a compaction time management form is created and output (S6).

  According to the compaction device 1 of the present embodiment, the slope is compacted by the slope shaping unit 21 and the top surface of the embankment structure is compacted by the top surface shaping unit 22 at the same time, so uniform shaping is easily performed. It can be carried out.

Since the slope shaping part 21 is formed in a trapezoidal shape, it can be compacted according to the shape of the corners. Similarly, since the upper surface shaping part 22 is also formed in a trapezoidal shape, it is possible to compact the upper surface of the embankment structure according to the shape of the corners.
Therefore, generation | occurrence | production of the part which becomes a quality weak point part (refer (a) shaded part of Drawing 6) by insufficient compaction can be controlled. In addition, when the entering corner is compacted by a conventional rectangular rolling element, a portion that cannot be compacted is generated (see the shaded area in FIG. 6A).

  Since the compaction operation is performed by setting the separation distance between the base machine and the rolling element 20 to a constant distance, the compaction energy for the whole embankment structure can be compacted.

  By position management using GPS, it is possible to work while confirming whether the construction position and construction specifications (consolidation energy, compaction time, etc.) are satisfied.

  The operator, the construction staff, the office, and the orderer must confirm the real-time compaction position and cumulative compaction time using the GPS antenna mounted on the base machine and the wireless LAN in the factory through the monitor. Therefore, construction can be carried out more reliably and with high quality.

  Since it is possible to form a recess for installing a seam stop plate without cutting the slope, it is possible to omit waste disposal costs, construction costs, and construction labor that accompany the cutting of the slope. it can.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiment, and the above-described components can be appropriately changed without departing from the spirit of the present invention.
