DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction apparatus for asphalt-based protective layer material for protecting the surface of asphalt pavement constructed on a slope of a reservoir or embankment, for example.

[0002]

2. Description of the Related Art As shown in FIGS. 4 to 6, a conventional construction comprises asphalt-based protective layer material M heated to 200.degree. The trolley A2 is moved upward along the slope N by the self-propelled winch B, the gate 21 at the bottom of the container 20 is opened, and the protective layer material M flows down to the front surface of the skieser 22, and is attached to the bottom surface of the skieser 22. The protective layer F having an average thickness of about 2 mm was formed by spreading the asphalt pavement surface E with the rubber plate 23 and spreading it.

[0003]

The protective layer F is formed with a uniform thickness if the asphalt pavement surface E is average. However, the rolled asphalt pavement surface E has many irregularities and cannot be formed as a flat surface such as a mirror surface. Therefore, the thickness of the protective layer F formed by the skizer 22 is such that the convex portions of the pavement surface E are thin and the concave portions are thick.

[0004] The thin portion of the protective layer F is quickly weathered and disappears due to deterioration of the asphalt due to the ultraviolet rays of the sun and the like, and the protective layer is partially lost and the protective layer must be formed again, which is uneconomical. It is.

[0005] Further, since the spread of the protective layer material by the skizer 22 can be performed only from the lower side of the slope N to the upper side, there is much time loss to move the skier 22 by moving the carriage A2, and the construction efficiency is poor.

According to the present invention, a protective layer can be formed uniformly irrespective of unevenness of a rolled asphalt pavement surface, and
It is an object of the present invention to provide an asphalt-based protective layer material construction device with good construction efficiency.

[0007]

According to the present invention, there is provided an asphalt-based protective layer material construction apparatus for protecting a surface of an asphalt pavement constructed on a slope, comprising a cart (A,
A1) is provided with an arm (2) movably in a direction orthogonal to the moving direction of the cart (A, A1), and the tip of the arm (2) is provided on the side of the cart (A, A1) with an asphalt system. A protective spray nozzle (6) is provided, and a heating vessel (7) for storing the asphalt-based protective layer material (M) is provided on the carts (A, A1), and the heating vessel (7) is fed by pressure. A pump (9) is connected and its pump (9)
Is connected to the spray nozzle (6) via a pipe (8), and a pulling wire (14) is stretched between the carriage (A, A1) and the self-propelled winch (B).

[0008]

Preferably, the movable arm is configured to be moved by a rack or sprocket meshing with a pinion of a drive motor and a chain.

[0010]

According to the present invention, since the protective layer material is sprayed from the spray nozzle at the tip of the arm to the side of the bogie, the protective layer material can be sprayed to a uniform thickness along the unevenness of the pavement surface.
Since the trolley does not ride on the spraying surface, reciprocating work can be performed both up and down along the slope.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, an arm 2 is supported by a pair of rollers 1 movably in one direction (left side in the illustrated example) at a rear portion of a bogie indicated by reference numeral A, in which all rear wheels can be steered. ing. A rack 3 is attached to the upper surface of the arm 2, and a pinion 4 of a drive motor 5 is engaged with the rack 3. And at the left end of the arm 2,
A pair of spray nozzles 6 are provided in the front-back direction.

On the other hand, a heating vessel 7 for storing the asphalt-based protective layer material M is provided at the front of the carriage A, and the vessel 7 is provided with a heating pipe indicated by reference numeral 8 as a whole. ing. The pipe 8 has a first pipe 10 bent leftward via a pressure pump 9 connected to the rear bottom of the container 7, and one end is pivotally connected to an end of the first pipe 10. And a third pipe 12 having one end pivotally connected to the rear end of the second pipe 11.
The other end of the pipe 12 is connected to a pair of spray nozzles 6. Therefore, when the motor 5 is operated and the arm 2 is moved rightward from the leftward movement position in the figure, the second and third pipes 11 and 12 are turned to the positions 11A and 12A. In the drawing, reference numeral 13 denotes an operation seat, and 14 denotes a pulling wire from the self-propelled winch B.

Next, an embodiment of the construction will be described with reference to FIGS. In the truck A1 shown in the figure, the arm 2 is provided at the front of the truck A1, and a pulling wire 14 is stretched between the truck A1 and the self-propelled winch B. The figure shows the construction of the ascending area C2. The bogie A1 is pulled up along the slope N by the pulling wire 14 from the self-propelled winch B. In this state, the arm 2 is reciprocated from the original position to the left position while the asphalt-based protective layer material M in the heating vessel 7 is sprayed from the spray nozzles 6 and 6 by the pressure feed pump 9.

As shown in FIG. 1, the relationship between the movement of the carriage A1 and the movement of the arm 2 is such that the movement of the carriage 1 by the movement distance D (for example, 0.8 m) at the spray width W (for example, 3 m). , Nozzles 6 and 6 are reciprocated once. Therefore, the asphalt-based protective layer F is formed by spraying twice.

When the construction of the ascending area C2 is completed in this way, the bogie A1 is moved to the uppermost position of the descending area C3 by operating the winch B and steering the front and rear wheels of the bogie A1, and the bogie A1 is sloped. While moving downward along the same manner as above.

[0017]

According to the present invention as described above, the following effects can be obtained.

(1) Compared to the conventional construction in which a protective layer material is spread and spread by a skier, the protective layer material can be applied to a uniform thickness along the unevenness of the pavement surface. It can be easily performed by changing the rotation speed of the pump.

(2) Since the spraying method is used, it is possible to perform reciprocating work in both the up and down directions instead of the one-way work from the bottom to the top unlike the spread and spread method, thereby improving the work efficiency.
