2. Description of the Related Art An eccentric load is attached to a rotary shaft provided on a rolling wheel along the center line of rotation of the rolling wheel, and the rotary shaft is rotated to vibrate the rolling wheel vertically with respect to its ground contact portion. Since the vibration roller having the mechanism propagates vertical vibrations through the ground, vibration noise pollution is likely to occur in construction in a residential area or in the vicinity of a facility where ground vibration is disliked. This is because the human sense is more sensitive to the vibration of the vertical component than the vibration of the horizontal component, and the vibration of the vertical component is a collision sound because it hits the so-called road surface. To do. Further, the vibrating roller that vibrates up and down has a drawback that small waves due to the vibration pitch are generated on the pavement surface when the amplitude is inappropriate or the rolling speed is high.

However, a vibrating roller that vibrates vertically has a wide range of utility value as a machine with high construction efficiency because it has excellent compaction performance in a relatively deep layer such as a lower roadbed. It is very useful in road construction, etc. away from facilities that dislike ground vibration, and cannot be replaced with a vibrating roller that vibrates horizontally. Therefore, in the vicinity of residential areas and facilities that dislike ground vibration,
Construction is being carried out to reduce vibration and reduce vibration pollution as much as possible. As a result, the construction efficiency was poor, and both machines were inevitably owned one by one, and there was a problem of financial burden.

At this time, the mutual relationship between the eccentrics 16a and 16b and the eccentric position are set as follows. That is, as shown in FIG. 3, the eccentrics 16a, 16b are eccentric with a phase difference of 180 degrees in the circumferential direction, and when they are rotated in the vertical state, the oscillating drive shafts 15a, 15b have the same vertical phase. It is fixed to. Therefore, the pair of vibration-driving shafts 15a and 15b are in a horizontal positional relationship with the road surface, and in the state of (b) in the figure, the eccentrics 16a and 16b.
Since both b are directed upward, a vibrational force directed in the U direction (upward) acts on the ground contact portion of the rolling wheel 2, and in the state (d), the eccentric 1
Since both 6a and 16b face downward, an oscillating force directed in the D direction (downward) acts on the ground contact portion of the rolling wheel 2. In the states (a) and (c), when the eccentrics 16a and 16b are facing right, they are facing left, and when they are facing left, they are facing right, so that centrifugal forces cancel each other. Therefore, the ground contact portion of the rolling wheel 2 receives a vertical action, and vertically vibrates directly below the roll.

First, in the initial rolling pressure in this method, the front rolling wheels 2 are made to be in a non-vibrating state, and the rear rolling wheels 4 are compacted while causing horizontal vibration. This initial rolling pressure is performed about twice (one reciprocation). Hair cracks (small cracks) may occur in the asphalt mixture or concrete spread with an asphalt finisher. This can be efficiently erased by compacting with a horizontally vibrating rolling wheel. In addition, it is possible to prevent the extrusion phenomenon in the next secondary rolling pressure by vibrating by applying horizontal vibration rather than rolling the front and rear rolling wheels 2 and 4 without vibration.

This secondary compaction is performed after the initial compaction so as to obtain a predetermined compaction degree. Due to vertical vibration,
In particular, sufficient compaction is performed up to the lower layer. In addition, if the vertical movement in the secondary rolling is applied as it is without erasing the hair crack at the initial rolling pressure, the hair crack expands and becomes a large crack.

According to the present invention having the above-mentioned structure, the vibration roller which can be used by selecting one of the vertical vibration and the horizontal vibration by switching the selection means in one machine can be used. The vibrating mechanism that causes vibration is composed of an oscillating drive shaft arranged symmetrically with respect to the center line of rotation of the rolling wheels and an eccentric attached to each oscillating drive shaft so that vertical vibration can be realized. Since it is configured, the vibration force of vertical vibration works vertically directly below the roll, and unlike the conventional uniaxial eccentric type, the vibration force does not act diagonally forward of the rolling surface, and cracks on the rolling surface do not occur. Can be prevented. Further, when the vibration force is directed diagonally forward of the compaction surface, the hopping phenomenon does not occur even when there is a hard roadbed B below the compaction layer.
Further, conventionally, there has been a problem that the reaction force of the vibration force diagonally forward of the compaction surface acts and the vibration of the roll becomes irregular, and particularly when a large amplitude is generated, the roll is laterally displaced. Then, since it becomes vertical vibration, stable running is possible.

Further, by adopting the pavement rolling method using the above vibrating roller, conventionally, two vibrating rollers, a vertical vibrating vibrating roller and a horizontal vibrating vibrating roller, are required. There is an effect that two vibrating rollers can work efficiently. Then, when performing paving rolling pressure using this vibrating roller, the initial rolling pressure is such that one rolling wheel is in a non-vibrating state and the other rolling wheel causes horizontal vibration to perform compaction. For rolling pressure, the other rolling wheel is in a non-vibrating state, and one rolling wheel causes vertical vibration to perform compaction.For finishing rolling pressure, one rolling wheel is in a non-vibrating state and the other rolling wheel is in a non-vibrating state. By constructing a pavement compaction method characterized by performing compaction while causing horizontal vibration, RCC especially called "compacted concrete pavement"
Effectively acts on P.
