Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rolling machine used for uniformly and reliably rolling a doughnut-shaped area to be rolled.

Conventionally, when repairing the paved road surface around circular road-occupied objects such as manholes and utility poles by locally replacing the paved road surface, the surrounding paved road surface is generally cut into rectangular or other square shapes, and the roadbed and roadbed are repaired. A widely used paving method is to compact the area and then pour asphalt on it for restoration. However, in the above-mentioned pavement construction method, since angular repairs are performed around circular road-occupied objects, distortion tends to occur in the repaired area, which leaves a feeling of discomfort and foreignness after the repair, and also impairs the aesthetic appearance. The shape of the pressure points includes circular arcs, straight lines, corners, etc., and the roadbed and roadbed cannot be compacted uniformly and reliably, so it is easy to cause steps, depressions, and other pavement damage after repair, which can lead to traffic accidents. If the repair area is expanded to improve the compaction workability in order to improve the lack of compaction, the number of man-hours will increase, which will be uneconomical, and the beauty and strength of the repair will be impaired. , there were problems such as unnecessarily expanding the scope of control of road occupiers.

In view of the above circumstances, the present inventor first attempted to solve the problems of the above-mentioned prior art at once by cutting the circumference of the circular road-occupied object into a circular shape and obtaining a doughnut-shaped rolling pressure point. However, the present invention relates to a rolling machine that can uniformly and reliably roll the doughnut-shaped area to be rolled, and includes a prime mover, a vibration device operated by the prime mover, and a vibration device operated by the vibration device. A rolling machine comprising a vibrating rolling plate that vibrates, characterized in that opposing side edges of the vibrating rolling plate are concentrically curved.

In the above-mentioned rolling compaction machine, the vibrating device includes one that generates vibration by reciprocating motion of the piston, and the vibrating compaction plate may be a foot portion of a rammer.

The vibrating compaction plate has opposing side edges concentrically curved in accordance with the donut-shaped location to be rolled, and has a divided donut shape, so it is well suited to the location to be rolled. It is possible, and the outer and inner peripheries can be effectively rolled. In this respect, commonly used rectangular vibrating compaction plates, vibratory compacting plates with only one side edge curved, or opposing side edges curved in opposite directions, etc.
Since it cannot fit into the doughnut-shaped portion to be rolled and pressed, it cannot achieve the above effect.

To explain the present invention based on the drawings, Fig. 1A
1 is a front view of a main part of a rolling compaction machine according to an embodiment of the present invention, and FIG. While operating the device 3, the vibration rolling plate 4 at the bottom
The opposing side edges 5a and 5b of the vibrating rolling plate 4 are concentrically curved.

FIG. 2 is a plan view of a paved road surface on which the compaction machine according to the present invention is used.
The surrounding existing paved road surface 7 is cut into a circular shape, and the vibrating compaction plate 4 (indicated by the dashed line) is used to roll compact the donut-shaped compaction area 8 of the roadbed or roadbed, etc., which has been repaired by local replacement. Possibly abutted. The opposing side edges 5a and 5b of the vibrating rolling plate 4 have the same or substantially the same degree of curvature as the outer peripheral part and the circumferential part of the donut-shaped rolled part 8, respectively.

As described above, according to the rolling machine according to the present invention,
Since the doughnut-shaped compacted area can be compacted uniformly and reliably, it is possible to improve the workability of the pavement, the size of the compaction machine, etc. during paving work that includes the process of cutting the circumference of circular road-occupied objects into a circular shape. Excellent compaction effects can be obtained with an extremely small repair area within the allowable range.
