Description

  The present invention relates to a litter collecting tool and a gutter block. More specifically, the present invention relates to a litter accumulation tool that accumulates litter collected on the side of a roadway, and a side groove block having a litter accumulation function.

  The rain that falls on the road is usually collected in a water collecting basin arranged on the side of the road, and discharged to a river or the like via a discharge pipe connected to the water collecting basin. A metal grating lid is fitted into the upper opening of the water collecting basin to prevent dust and the like from flowing into the water collecting basin.

  By the way, a part of the fallen leaves from the roadside trees planted along the road falls to the side of the road, is washed along the road edge by rain water, and accumulates in the vicinity of the grating lid of the water collecting basin. While the amount of accumulated fallen leaves is small, rainwater can flow into the catchment basin through the gaps between the fallen leaves or avoiding fallen leaves, but if left untreated, the fallen leaves gradually accumulate. Covering the grating lid and forming a bank, the inflow of rainwater into the catchment basin is obstructed. As a result, there is a problem that a water pool can be formed on the side of the road, and water jumps to a pedestrian on the sidewalk when the vehicle passes. Further, since the tires are likely to slip, it is dangerous especially when traveling with a two-wheeled vehicle such as a bicycle.

  Patent Document 1 discloses a road that is continuous with a road in order to eliminate problems (such as making it difficult to distinguish pedestrian roads and making it easier for vehicles to derail) due to defoliation and dirt accumulated in drain grooves at the road edge. A side groove block including a surface portion, a side lump portion, and a drainage groove portion between the road surface portion and the side lump portion is disclosed. Concavities and convexities are formed on the road surface, and running water from the road is gathered by the raised walls of the irregularities, and the gathered water flows into the drainage grooves. And the momentum of water is strengthened by being gathered by the said unevenness | corrugation, and when the water flows into a drainage ditch, the fallen leaves and dust which are staying in the said drainage ditch are pushed away.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a litter collecting tool and a side groove block according to the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 is an explanatory plan view showing an installation example of a litter collecting tool according to an embodiment of the present invention, and FIG. 2 is a cross-sectional explanatory view taken along line AA in FIG. The leaf litter stacking tool 1 is provided in a rainwater flow path at the end of the road, in other words, on a moving path of the leaf fallen away by rainwater. In the present embodiment, the defoliation stacking tool 1 is fixed to the upper surface of the block body 5 constituting the side groove block 4 disposed at the boundary between the roadway 2 and the sidewalk 3. In FIG. 2, 11 is a roadway asphalt constructed on the basic crushed stone 12, and 13 is a sidewalk asphalt constructed on the basic crushed stone 14.

  The side groove block 4 includes a block body 5 having a rainwater flow path surface 6 on the upper surface. In the present embodiment, the standing wall 7 functioning as a walking path boundary block that partitions the roadway 2 and the sidewalk 3 includes Along the side edge of the flow path surface 6 on the sidewalk side, the block body 5 is formed integrally. A flow path 10 having a circular cross section for discharging rainwater is formed in the block body 5 along the longitudinal direction. The side groove block 4 is installed at a predetermined location on the roadside through abandoned concrete 16 on the ground crushed stone 15.

  The flow path surface 6 is an inclined surface that is inclined downward toward the sidewalk, and rainwater on the roadway 2 flows on the inclined surface toward the standing wall 7, and then the water collecting trap along the standing wall 7. It flows toward 8. The catchment basin 8 is disposed (buried) at a predetermined interval in the longitudinal direction of the road on the side of the road, and foreign matter such as fallen leaves and garbage is prevented from entering the catchment basin at the upper opening. A grating lid 9 is fitted. The flow path 10 of the block main body 5 communicates with the water collecting basin 8.

  At the side edge of the block main body 5 on the flow path surface 6 on the side of the standing wall 7, a leaf fall accumulation tool 1 for depositing or accumulating the fall leaves flowing along with the rain water on the flow path surface 6 is disposed. As shown in FIGS. 3 to 4, the defoliation stacking tool 1 covers a strip plate plate 20 that is a plurality of protrusions and the strip plate plate 20, and the strip plate plate 20 is covered with the flow path surface 6. And a substantially semi-circular sheet body 21 for fixing to a sheet. More specifically, the defoliation stacking tool 1 has three strip plate plates 20 provided along the cross direction of the road, and these three strip plate plates 20 are arranged in the cross direction of the road. Are evenly spaced along.

  The distance d between the adjacent band plate-like plates 20 is not particularly limited in the present invention, but is preferably not more than the size (width) of the fallen leaf in order to hook the fallen leaf more reliably. It is selected within a range of 10 to 50 mm. The height h of the belt-like plate 20 is preferably higher to some extent from the viewpoint of easy catching of fallen leaves. However, considering the safety of vehicle traffic, it is desirable that the height h is about the depth of flowing rainwater. . Specifically, it is usually about 40 mm at the maximum, and about 20 to 5 mm in consideration of safety. Further, the width w of the strip plate 20 is selected to be smaller than the distance d. The distance d, height h, and width w are selected from the viewpoint of efficiently depositing defoliation in addition to the above factors. In the case of a road with a general amount of defoliation, the distance is 20-30 mm and the height is 5 mm. The width is preferably 10 mm.

  The size m in the road longitudinal direction and the size n in the road crossing direction of the semicircular sheet body 21 are the width W of the flow path surface 6 (see FIG. 1, size in the road crossing direction), the amount of fallen leaves, or the amount of rainwater. It can be selected based on road conditions (gradient, etc.), but is usually 50 to 400 mm and 20 to 200 mm, respectively. In addition, the shape of the sheet | seat body 21 can employ | adopt suitably other shapes, such as a rectangle, besides the said semicircle.

  The material of the strip plate 20 is not particularly limited in the present invention, but can be made of a synthetic resin such as vinyl chloride resin, stainless steel, or the like. In addition, the sheet body 21 is preferably made of a material having a certain degree of flexibility so that it can be fixed to the flow path surface 6 in a state of covering the strip plate 20, and a material having weather resistance and wear resistance, For example, it can be made of a rubber sheet having a thickness of about 1 to 5 mm and a synthetic resin sheet such as a soft vinyl chloride resin.

  The sheet body 21 can be fixed to the flow path surface 6 using an adhesive, but the entire sheet body 21 is made of a heat-weldable material, or comes into contact with a road in the sheet body 21. By forming a layer made of a heat-weldable material on the side surface, it can be fixed to the flow path surface 6 using heat. In the latter case, the sheet body 21 is pressed against the previously heated flow path surface 6, and the sheet body 21 is further heated, and the fallen leaf accumulation tool 1 is fixed to the flow path surface 6 without using an adhesive ( Can be fixed).

  Moreover, it is preferable to perform a non-slip process on the surface of the sheet body 21 opposite to the side in contact with the road. For example, non-slip processing can be performed by forming irregularities on the surface of the sheet body 21 or attaching glass aggregate or the like. According to this configuration, since the non-slip processing is applied to the road side surface of the seat body 21, even if a bicycle or the like passes over the seat body 21, the handle can be slipped and taken off. It can be surely prevented.

  For example, a rosin grip (trade name, a heat-weldable anti-slip material manufactured by Ito Yogi Co., Ltd.) can be used as a sheet having heat-weldability and non-slip processing on one side. This rosin grip is a sheet mainly composed of a natural material (pine ani), and a glass aggregate is attached to one side. In use, the glass aggregate is fixed to the flow path surface 6 by heat welding with the surface to which the glass aggregate is attached facing up. When this rosin grip is used, the effect that it is possible to follow the unevenness of the flow path surface 6 at the site to some extent is also obtained.

  The leaf litter collecting tool 1 is arranged at a predetermined interval along the road longitudinal direction according to the amount of leaf litter, etc., and the interval a (see FIG. 1) with the grating lid 9 is 50 cm or more. It is preferable that the interval b between the tools is 100 cm or more from the viewpoint that the fallen leaves can be dispersed and deposited appropriately and the flow of rainwater can be secured.

  According to the litter collecting tool 1, the plurality of strip plate plates 20 are provided in the flow path of rainwater at the road end, in other words, the movement path of the litter flowed by the rainwater. The part is caught by the strip plate 20 and stays there. Then, it is possible to gradually accumulate (accumulate) subsequent fallen leaves using the staying fallen leaves as a nucleus. By providing several such litter collecting tools 1 on the upstream side of the water collecting basin 8, it is possible to disperse the litter accumulation concentrated near the grating lid 9 as in the prior art. Thereby, it is possible to mitigate the rainwater flow being blocked by the fallen leaves concentrated in the vicinity of the grating lid 9, and it is possible to prevent a large pool of water from being formed at the end of the road.

  In the present embodiment, since the strip plate 20 is provided substantially parallel to the rainwater flow, the extent to which the rainwater flow is obstructed by the strip plate 20 can be reduced and smoothly. Rainwater can be drained to the catchment 8. Moreover, since the fallen leaves can be hooked by the longitudinal end portion of the band plate-like plate 20, the action of accumulating the fallen leaves can be exhibited.

In addition, the shape and size of the protrusion for hooking the fallen leaves are not limited to those of the above-described embodiment (band plate), but the size of the fallen leaves, the amount of fallen leaves, and the earth and sand flowing on the flow path surface. It can be appropriately changed according to the conditions of each site such as the type.
For example, instead of the embodiment of FIG. 3 in which a strip plate plate is provided in the crossing direction of the road, the strip plate plate 20 may be provided in the longitudinal direction of the road, as shown in FIG. Further, as shown in FIG. 6, the strip plate may be provided obliquely with respect to the crossing direction or longitudinal direction of the road. Furthermore, a coin-shaped or dome-shaped protrusion 40 as shown in FIG. 7 can be used in addition to the belt-like plate.

  In the embodiment shown in FIGS. 3 to 4, the strip plate 20 and the sheet body 21 are separate, and the strip plate 20 is fixed to one surface of the sheet body 21 (adhered to the road) for easy handling. Is temporarily fixed by adhesive or heat welding. As described above, when the band plate-like plate 20 and the sheet body 21 are separated, there is an advantage that a material suitable for each can be selected. However, the litter collecting tool of the present invention is limited to this. Instead, the band plate plate 20 and the sheet body 21 may be integrally formed of rubber or a synthetic resin such as soft vinyl chloride resin. In this case, an effect that the number of parts is reduced and handling is easy can be obtained. This integrated defoliation collecting tool can be fixed to the flow path surface 6 using, for example, an adhesive.

  In addition to fixing a separate litter collecting tool on the flow path surface of rainwater, it is also possible to form a protrusion that hooks the litter onto the side groove block itself constituting the flow path surface. That is, in the vicinity of the side edge on the sidewalk side of the flow path surface 6 of the block body 5, a plurality of protrusions having a height capable of locking the fallen leaves can be formed integrally with the block body 5. In this case, since the plurality of protrusions are integrally formed with the block main body 6, it is possible to save the trouble of mounting on the road surface.

Even in this case, the plurality of protrusions are preferably formed of a plurality of ridges provided side by side in the crossing direction of the road, and the ridges are provided substantially parallel to the flow of rainwater. The extent to which the rainwater flow is obstructed by the ridges can be reduced, and rainwater can flow smoothly to the catchment. And since the fallen leaf can be hooked by the longitudinal direction edge part of the said protruding item | line, the accumulated action of fallen leaf can be exhibited.
As the side groove block, not only the type having the standing wall 7 functioning as a walking road boundary block as shown in FIG. 2, but also the type having no walking road boundary block 30 as shown in FIG. Is also included. In the side groove block 4 shown in FIG. 8, the upper surface of the block body 5 is a flow path surface 6, and the pedestrian path is engaged with a step portion 32 formed along the side edge of the flow path surface 6. A boundary block 30 is provided. Then, three ridges 31 are provided in the road crossing direction in the vicinity of the side edge of the flow path surface 6 on the sidewalk.
