However, Patent Document 1 does not describe a specific construction apparatus and a construction method thereof. Here, if it estimates about the construction apparatus and construction method which concern on patent document 1, it will be thought that a groove is formed by hitting a paving body with the stamper attached to the rear part of the paving machine.
As described above, when the groove is formed by striking the stamper, there are the following problems.
(1) Noise and vibration become intense, and construction in urban areas is particularly difficult.
(2) Since the groove interval is determined by the traveling speed of the self-propelled roller body and the timing of hitting, the speed of the self-propelled roller must be kept constant, and grooves are formed at equal intervals. Is difficult.
(3) Since the construction is performed by hitting the paved body after compaction, the shape of the groove tends to collapse.
Moreover, when a stamper is provided at the rear part of the paving machine as in the present invention, it is considered that the alignment when forming the groove is difficult and the construction efficiency is lowered.

According to such a configuration, when a self-propelled roller for pavement construction (hereinafter simply referred to as “self-propelled roller”) is installed on the pavement and the rotating body is moved downward, the surface of the pavement is The protrusion will bite. Thereby, a groove is formed in the pavement. Further, when the rotating member is self Hashishiki roller body is moved, the rotating body is to rotate with it. And since the protrusion is formed in the surface of the said rotary body, a protrusion will bite into the next point with rotation of a rotary body, and a groove | channel will be formed sequentially. Thereby, a groove | channel can be continuously formed with the movement of a self-propelled roller, and construction efficiency can be improved.
The self-propelled roller rolls using vibration generated by the eccentric drum, and the pavement vibrates when rolled while vibrating the drum. Therefore, by pressing the protrusions on the vibrating pavement, the protrusions can be easily bite into the pavement and a well-shaped groove can be formed. Further, even when a relatively large protrusion is used, the pavement vibrates, so that the protrusion can be easily bited into the pavement and a groove having a relatively large cross section can be formed.

Also, the self-propelled rollers, since it is intended to press the protrusions while rotating the rotating member, in forming a groove in a conventional manner, for applying a groove banging pavement portion forming a groove Since it is not a thing, a noise and a vibration can be suppressed.

<Configuration of self-propelled roller (self-propelled roller for pavement construction )>
FIG. 1 is a side view showing a self-propelled roller 1 according to the present embodiment. FIG. 2 is a plan view showing the self-propelled roller 1 according to the present invention. FIG. 3 is a rear view showing the self-propelled roller 1 according to the present invention.

As shown in FIGS. 1 to 3, the self-propelled roller 1 according to this embodiment includes a self-propelled roller body 2 and a groove forming device 20 attached to the rear left side of the self-propelled roller body 2.
The self-propelled roller 1 can perform not only the normal rolling operation but also the rolling operation and the groove forming operation simultaneously by the operation of the groove forming device 20 described later. Moreover, since these construction modes can be changed easily and appropriately, construction efficiency can be improved.
Further, since the self-propelled roller 1 forms the groove M by utilizing the rotational action of the self-propelled roller 1 at the time of groove formation construction, it is not necessary to strike the pavement G to construct it, and noise and vibration Can be suppressed.
Below, each structure of the self-propelled roller 1 is demonstrated.

<Self-propelled roller body>
The self-propelled roller body 2 compacts the pavement body G by repeatedly moving on the pavement body G in the front-rear direction. The self-propelled roller main body 2 exhibits the effect of compacting the pavement G by its weight. For example, the total weight of the self-propelled roller main body 2 according to this embodiment is 6 t.
As shown in FIGS. 1 to 3, the self-propelled roller body 2 in the present embodiment is a tandem roller having a body part 3, a front iron ring drum 4, and a rear iron ring drum 5 (diameter about 122 cm). The airframe unit 3 has a handle 7 for turning the operator seat 6 and the self-propelled roller body 2 in the left-right direction. There is an accelerator 8 at the foot of the operator seat 6, and when the accelerator 8 is stepped on, an engine (not shown) in the center of the body part 3 is driven and the self-propelled roller body 2 moves. On both the front and rear side surfaces of the self-propelled roller main body 2, plates 9 for connecting the machine body 3 and the iron drum are provided.
In addition, the self-propelled roller body 2 includes a front mirror 10 and a rear mirror 11 for visually confirming directly under the self-propelled roller 2 in front and rear of the self-propelled roller body 2, and the airframe unit 3. Rear mirrors 12 are provided on both sides of the central side for confirming rear safety.
Further, the front iron drum 4 and the rear iron drum 5 of the self-propelled roller body 2 are configured to have the same diameter and the same length, and the linear pressure of each wheel is equal, so that reliable and uniform compaction can be achieved by one pass. Can be made possible.

The self-propelled roller body 2 may be a vibrating roller (not shown). For example, if the self-propelled roller body 2 is a tandem vibration roller, both the front iron drum 4 and the rear iron drum 5 vibrate, so that a high compaction density can be obtained with a small number of times of rolling and the construction efficiency can be increased. it can.
Moreover, when the pavement G is pressed using the vibration roller, the pavement G also vibrates. Therefore, at the time of the groove formation construction, the projection 21 is pressed by the vibrated pavement G, so that the projection 21 can be easily bited into the pavement G, and the groove M having a uniform shape can be formed.

  The vibration roller may be a horizontal vibration roller (not shown). Since the drum does not always come in contact with the pavement G and does not strike the pavement G, the horizontal vibration roller can prevent crushing and noise of the pavement material. Further, since the horizontal vibration roller can reduce vibration propagation to the periphery, a vibration suppressing effect can be achieved. In addition, the horizontal vibration roller can also press the protrusion 21 against the pavement G in a vertical direction by using the horizontal vibration so that the rotating body 22 and the protrusion 21 can be moved little by vertical movement even when the groove is formed. The protrusion 21 bites better than the directional vibration. Therefore, the groove M can be formed stably.

  Further, the self-propelled roller body 2 may have other forms. For example, even a Macadam roller or a tire roller can exhibit the same effect as this embodiment.

<Groove forming device>
The groove forming device 20 is a device for forming the groove M on the surface of the pavement G. In the present embodiment, the groove forming device 20 is disposed on the left side of the rear iron drum 5 of the self-propelled roller 1.

The rotating body 22 rotates with the movement of the self-propelled roller body 2.
As shown in FIGS. 2 and 3, the rotating body 22 has a short cylindrical shape (diameter of about 90 cm), and the column length is substantially equal to the traffic division line width. As shown in FIG. 4, the rotating body 22 is pivotally supported by a lower U-shaped bracket 26 whose lower part is opened and a horizontal U-shaped bracket 28 whose rear part is opened. The upper end of the lower U-shaped bracket 26 is connected to the upper portion of the upper U-shaped bracket 25 via a vertical hydraulic cylinder 23.
Therefore, after the rotating body 22 is moved downward and the protrusion 21 is bitten into the pavement G, the rotating body 22 rotates smoothly as the self-propelled roller body 2 moves.

<Protrusions>
The protrusion 21 forms the groove M by pressing the pavement G.
In the present embodiment, the protrusions 21 are trapezoidal horizontal columns that become narrower as they move away from the rotating body 22, and are arranged on the outer peripheral surface of the rotating body 22 at equal intervals perpendicular to the rotation direction. Has been.
In the present invention, since the groove M is formed by utilizing the rotating action of the rotating body 22, if the protrusion 21 is a horizontal column having a rectangular cross section, the groove M may be formed during pressing or peeling. The corner portion is cut, and the well-shaped groove M cannot be formed.
However, as in this embodiment, the protrusion 21 is a horizontal columnar body having a trapezoidal cross section that becomes narrower as it moves away from the rotating body 22, so that pressing and peeling to the pavement G is smooth and the finished surface is in order. A groove M can be formed.
Moreover, since the peripheral wall of the formed groove | channel M inclines inside by making the protrusion 21 into such a shape, the defect | deletion of the groove | channel M by motor vehicle travel can be prevented as much as possible.

  In the present embodiment, since the protrusions 21 having the same shape and size are arranged at equal intervals, the grooves M having the same shape and size are naturally formed at equal intervals. However, the present invention is not limited to this, and various variations of the groove M can be formed by appropriately changing the interval, shape, and size of the protrusions 21 according to the sound of alerting and vibration. it can.

<Support structure>
In the groove forming device 20, the upper U-shaped bracket 25 and the middle U-shaped bracket 27 are screwed to the left rear plate 9 of the self-propelled roller body 2, and are fixed to the self-propelled roller body 2. ing. As described above, since the welding of the self-propelled roller body 2 and the groove forming device 20 is not used, it can be easily attached and detached.
In the present embodiment, the groove forming device 20 is attached to the left side of the self-propelled roller body 2, but may be attached to the right side or may be attached to both sides.

The rotating body 22 is pivotally supported by a lower U-shaped bracket 26 and a horizontal U-shaped bracket 28. The middle U-shaped bracket 27 guides the vertical movement of the lower U-shaped bracket 26, covers the upper end of the lower U-shaped bracket 26, and is fixed to the upper U-shaped bracket 25 by welding. Yes. The upper end of the lower U-shaped bracket 26 is connected to the upper U-shaped bracket 25 via a vertical hydraulic cylinder 23. The vertical hydraulic cylinder 23 is connected to a hydraulic pressure adjusting device (not shown), and can be expanded and contracted by adjusting the operation lever 29. With such a support structure, the rotating body 22 can move in the vertical direction.
In addition, the rotating body 22 is pin-supported through a steel arm 24 and a horizontal U-shaped bracket 28 with respect to the axis of the rotating body 22 and the central lower portion of the airframe unit 3.
As described above, the structure can maintain a strong support force against vibrations in the vertical direction and the horizontal direction and can follow the movement of the rotating body 22 in the vertical direction.

<Pavement construction method 1>
It continues and the construction method of the paving body G is demonstrated.
First, as shown in FIG. 4, the self-propelled roller 1 according to the present embodiment is moved to the groove forming region R (FIG. 6) in a state where the rotary body 22 is moved upward to the pavement G that has finished the primary rolling. (See reference). When the groove forming device 20 is attached to the left side in the traveling direction of the self-propelled roller body 2 as in the present embodiment, the self-propelled roller 1 is disposed on the right side of the groove forming region R.
Here, the groove forming region R is a range in which unevenness is provided on the pavement G, and an abnormal sound / vibration is generated even if the automobile deviates from the traveling range, and is alerted mainly. The range where is provided.
Next, as shown in FIG. 5, the rotating body 22 is moved downward to the position where the protrusion 21 bites into the pavement G by the operation lever 29. When the self-propelled roller 1 is moved along the groove forming region R, the rotating body 22 rotates on the groove forming region R along with this movement. Thereby, the protrusions 21, 21... Arranged on the rotating body 22 are sequentially pressed against the groove forming region R, and the grooves M are formed efficiently and continuously.
Further, when the groove forming construction is finished or interrupted, the rotating body 22 is moved upward, and the protrusion 21 is lifted from the pavement G, so that the normal rolling construction can be easily performed.
Moreover, since this method uses the rotating action of the self-propelled roller 1, it is not necessary to strike the pavement G, and noise and vibration can be suppressed.

<Pavement construction method 2>
The construction method 2 of the pavement G uses the self-propelled roller body 2 of the construction method 1 of the pavement G as a vibrating roller. Therefore, since the groove forming procedure is the same as the pavement construction method 1, description of the procedure is omitted.
When rolling is performed using a vibration roller, the pavement G vibrates during compaction. Since the protrusion 21 is pressed against the vibrating pavement G, the protrusion 21 can be easily bited into the pavement G, and the groove M having a well-formed shape can be formed. Further, even when a relatively large protrusion 21 is used, the pavement G vibrates, so that the protrusion 21 can be easily bited into the pavement, and a groove M having a relatively large cross section is formed. Can do.
Moreover, by using the vibration roller as a horizontal vibration roller, it is possible to perform rolling so as to slide in the horizontal direction. That is, since the iron drum of the horizontal vibration roller does not come in contact with the pavement G and does not hit the pavement G for construction, crushing and noise of the pavement material can be prevented. Further, since the rotary body 22 and the protrusion 21 have little vertical movement, and the protrusion 21 can bite into the pavement G as if sliding, the protrusion 21 bites better than the vibration in the vertical direction, and the groove M is stabilized. Can be formed.

<Pavement construction method 3>
FIG. 6 is a diagram showing the construction method 3 of the pavement over time, (a) is a first surface rolling step, (b) is an alignment step, (c) is groove formation and second surface rolling. It is a figure showing the state of the pressurization process. Here, as shown in FIG. 6, the first surface refers to a rolling portion including the groove forming region R, and the second surface refers to a rolling portion adjacent to the first surface.
In FIG. 6, the hatched portion represents an unpaved body, and the white portion represents an already paved body.

First, as shown to Fig.6 (a), in the state which floated the rotary body 22 of the self-propelled roller 1 from the pavement body G, a 1st surface is rolled (refer FIG. 4).
Next, as shown in FIG. 6B, the self-propelled roller 1 is installed along the groove forming region R, and the rotating body 22 is moved downward to a position where the protrusion 21 bites into the pavement G (see FIG. 6B). 5).
Then, as shown in FIG. 6C, the self-propelled roller 1 is moved forward to roll the second surface, and at the same time, the groove M is formed in the groove forming region R of the first surface.
By taking such a method, after rolling the first surface, when rolling the second surface adjacent to the first surface, the position of the rotating body 22 is placed in the groove forming region R of the first surface. By matching, the groove M can be formed in the pavement G on the first surface while rolling the second surface. Thereby, construction efficiency can be improved.
The groove M is preferably formed before the first surface pavement G is cured. According to the method, the groove M is formed in the groove forming region R immediately after the first surface is rolled. Therefore, construction quality and construction efficiency can be improved at the same time.
In addition, when complete | finishing or interrupting groove | channel formation construction, by moving the rotary body 22 upwards and making the protrusion 21 float from the pavement G, it can transfer to normal rolling construction easily.
