  However, in the above-described conventional slope construction apparatus, the entire apparatus is sequentially moved in the longitudinal direction of the slope, and the spreader is moved in the vertical direction of the slope every time. When the distance in the direction is short and the area to be paved with a single relocation is small, the construction efficiency becomes low.

  Therefore, it is desirable to extend the working surface of the leveling means in the longitudinal direction of the slope to increase the area that can be paved at one time, but the slope is curved in the horizontal direction and its curvature is small However, there is a problem that the work surface that is wide in the longitudinal direction of the slope surface does not follow the curved surface, and the work surface partially floats, so that the paving work of the curved surface becomes complicated.

  In the present invention, the slope can be paved continuously in the longitudinal direction, the construction efficiency can be improved, and the curved surface is curved even when the curvature of the slope that is curved in the horizontal direction is small. It aims at providing the slope construction apparatus which can be paved easily.

In order to solve the above-mentioned problems, the present invention provides a slope construction device for paving a slope, an upper traveling means that is movable in the longitudinal direction of the slope along the upper end of the slope, The pavement material supported on the slope is supported by the lower running means that can move in the longitudinal direction of the slope along the lower end of the face, and the upper running means and the lower running means. A main body portion having leveling means for leveling in the longitudinal direction, and the upper traveling means and the lower traveling means are each independently attached to the main body portion so as to be freely movable in the front-rear direction. It is characterized by having.

  According to this configuration, the main body having the leveling means for spreading the pavement material in the longitudinal direction of the slope can be moved in the longitudinal direction of the slope by the upper running means and the lower running means. Therefore, the slope can be paved continuously in the longitudinal direction, and the construction efficiency can be improved.

  Further, the spread leveling means is configured to level the pavement material in the longitudinal direction of the slope, and its work surface is wide in the vertical direction of the slope and wide in the longitudinal direction of the slope. Narrow. As a result, when paving a slope that is curved in the horizontal direction, even if the curvature of the slope is small, the entire work surface of the leveling means can be made to follow the curved surface, so the curved surface can be paved easily. can do.

Further, when the slope construction device is turned in the horizontal direction along the curved surface of the slope that is curved in the horizontal direction, the running means is moved forward and backward in the running direction so that the running means becomes inside the turning direction. Is shifted backward with respect to the outer traveling means, the minimum turning radius of the slope construction device can be reduced. Thereby, even if it is a case where the curvature of a slope is small, a slope construction apparatus can be smoothly turned along a curved surface.
Further, the upper traveling means and the lower traveling means may be provided with a front traveling means and a rear traveling means, and the front traveling means may be configured to be movable back and forth in the traveling direction with respect to the main body.

  In the slope construction device described above, the upper traveling means and the lower traveling means can be configured to be provided with driving means, respectively.

  In this way, by providing the driving means in the upper traveling means and the lower traveling means, each traveling means can travel independently. Thus, when the predetermined traveling means is moved back and forth in the traveling direction, the traveling means can be moved and moved independently, so that the traveling means can be easily moved.

According to the present invention, it is possible to move the main body portion having the spread leveling means for spreading the pavement material in the longitudinal direction of the slope in the longitudinal direction of the slope, so that the slope is continuous in the longitudinal direction. Can be paved and the construction efficiency can be improved.
In addition, the working surface of the leveling means is wide in the vertical direction of the slope and narrow in the longitudinal direction of the slope, so when paving a slope that is curved in the horizontal direction, Even if the curvature of the surface is small, the work surface of the leveling means can be made to follow the curved surface, so that the curved surface can be paved easily.

A predetermined amount of pavement material is introduced. And the slope construction apparatus 1 is moved toward the front by driving each upper side travel means 10a, 10b and each lower side travel means 20a, 20b.

While moving the slope construction apparatus 1 forward, the pavement material is supplied from the supply hopper 41 onto the slope surface N, spreads in the left-right direction (up and down direction of the slope N) by the screw 42, and is paved by the screed 43. To a certain thickness.
Further, after paving the pavement material having a constant thickness with a vibration roller (not shown) or the like, the pavement is straightened for a certain period, thereby completing the pavement in the straight section of the slope N.

  Moreover, as shown in FIG. 4, when the slope N is curved to the left in the longitudinal direction, the curved surface of the slope N is paved while turning the slope construction device 1 to the left. At this time, the front upper traveling means 10a is moved rearward in the traveling direction, and the front upper traveling means 10a that is inside the turning direction is rearward with respect to the front lower traveling means 20a that is outside the turning direction. In a shifted state, the slope construction device 1 is turned to the left along the slope of the slope N.
