Abstract

(57) [Abstract] [PROBLEMS] On a road provided with a sound insulation wall, snow accumulates at the corner where the front surface of the sound insulation wall and the upper surface of the guard side wall of the road where the sound insulation wall is attached are covered with snow, and the road surface gets wet with the melted snow water. It may freeze, so reduce it. SOLUTION: A draining plate 5 for closing a gap between a side wall 2 and a sound insulation wall 1 provided outside the side wall is provided with one side portion fixed to an upper surface of the side wall 2 and another side portion fixed to the sound insulation wall 1. The space between them is curved in a concave shape, and the drainage plate 5 creates a slope on which the snow slides.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a drainage structure in front of a sound insulation wall, which is effective as a measure to reduce freezing of roads with sound insulation walls.

[0002]

[Prior art]

 Sound insulation walls will be installed on both sides of the highway running in and around the city to prevent noise.

As shown in FIG. 5, the sound insulation wall 1 is attached to the guard side walls 2 on both sides of the road HW in the case of a bridge type road. This mounting is carried out by fixing a pillar 3 made of H-shaped steel to the outer surface of the side wall 2 and fitting the sound insulation walls 1 into the grooves on both sides of the pillar 3.

Therefore, the sound insulation wall 1 is located outside the side wall 2, and at the front part of the sound insulation wall 1, there is formed an L-shaped corner 4 where the front surface of the wall and the upper surface of the side wall 2 intersect. A drain plate 5 is attached to the L-shaped corner 4 in order to prevent rainwater and the like from dripping from the gap between the sound insulation wall 1 and the side wall 2. However, the conventional drain structure using the drain plate is effective for removing snow. However, the road surface was frozen in a snowy area.

[0005]

[Problems to be solved by the device]

 The conventional draining plate has an L-shaped cross section. As shown in FIG. 6, the narrow side is closely attached to the front surface of the sound insulation wall 1, and the wide side is closely attached to the upper surface of the side wall 2, respectively. It is fixed in place with a toe 6.

However, in the conventional draining structure using the draining plate, the L-shaped corner 4 is left as it is, and this portion becomes a snow accumulation portion.

[0007] Compared to snow on the road, the snow accumulated on the L-shaped corners is slow to melt, and even after the snow on the road is removed, the snow-melting water flows out from the L-shaped corners to wet the road surface. And it freezes in the cold at night. As a result, the number of road surface freezes increases and a slip accident is triggered.

This invention intends to provide a drainage structure for the front part of the sound insulation wall, which is effective in eliminating such a problem.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a draining plate is fixed to one side of the upper surface of a side wall of a road and the other side of the draining board to the front surface of a sound insulation wall attached to the outside of the side wall. The corner between the one side and the other side is curved in a concave shape, and the draining plate covers the above L-shaped corner.

The draining plate used is preferably a stainless steel plate having excellent corrosion resistance. It is desirable that the surface of this drainage plate be treated to prevent reflection of light. Also, for transportation reasons, it is desirable to elastically deform in the field and bend it into a concave shape.

[0011]

[Action]

 If the above-mentioned draining plate is used, a curved slope will be created at the corner that was previously L-shaped, and snow will slide down on the slope. Therefore, a large amount of snow will not accumulate in front of the sound insulation wall, and road freezing due to snow melt water from there will be reduced.

If the surface of the draining plate is subjected to a light antireflection treatment, the reflection of light by the draining plate is weakened, and the driver of the vehicle does not have to feel dazzling.

Further, when the draining plate is curved on site, the draining plate does not become bulky at the time of loading, and the efficiency of transportation is deteriorated and the transportation cost is prevented from rising.

[0014]

1 and 2 show an embodiment of the draining structure of the present invention. As shown in the figure, in the present invention, the draining plate 5 is bent in the width direction in a concave shape in the installed state. The draining plate 5 used here is made of a stainless steel plate whose surface is coated for matting.

The draining plate 5 is an elongated plate having a width W of about 300 mm and a length L of about 1800 to 1900 mm as shown in FIG. 3, and the embedded bolt 6 is inserted into the side of the upper surface of the side wall 2. A plurality of mounting holes 5a are formed at a constant pitch. Further, on the side of the sound insulating wall 1 which is to be attached to the front surface, a small-width bent portion 5b bent in an L shape is formed.

A drainer plate 5 having a shape close to this flat plate is elastically deformed at the installation site as shown in FIGS. 1 and 2 to be bent in a concave shape, and one side is fixed to the side wall 2 with an embedded bolt 6. To do. The other side is fixed by welding the edge of the bent portion 5b to the front surface of the sound insulation wall 1. Thus, the attachment of the draining plate 5 is completed, and the gap formed between the side wall 2 and the sound insulation wall 1 between the adjacent columns 3 and 3 is closed by the draining plate 5.

With such a water draining structure, the snow draining plate 5 serves as a slide, and snow that tends to accumulate on the water draining plate slides down to the roadside belt side. Therefore, a large amount of snow does not accumulate on the upper portion of the side wall 2.

The drainer plate 5 in FIG. 3 is slightly bent at one side along the bending line 5c in the direction opposite to the bending direction of the other side at an angle of θ. The draining plate 5 as shown in Fig. 4 which has not been bent can achieve the purpose of the invention by mounting it by bending it into a concave shape. However, as shown in Fig. 3, a crease by a bending line 5c is added. If this is done, one side will be brought into close contact with the upper surface of the side wall 2 smoothly, and workability at the time of attachment and appearance after attachment will be improved.

[0019]

[Effect of device]

 As described above, in the present invention, the gap between the side wall of the road and the sound insulation wall is closed by the drain plate having the concavely curved corner, so that the drain plate has a natural phenomenon of removing snow. A large amount of snow will not be accumulated on the corner created by the side wall and the sound insulation wall. Therefore, road surface freezing due to snow melt water from here is reduced, and slip accidents are reduced.

It should be noted that since the water drainage plate can be bent on site to efficiently convey the water, it is possible to avoid an increase in the transportation cost due to the adoption of the water drainage structure of the present invention.
