Description

TECHNICAL FIELD The present invention relates to a road surface water guide device, and more particularly to a road surface water guide device used to dam running water on a road surface and guide it to the roadside.

Forest roads and working roads in mountainous areas are generally unpaved, and when long-distance running water occurs during rain, the road surface is scoured or eroded along the track of the running water, making it difficult for heavy machinery and work vehicles to move. It may become difficult to drive. Therefore, measures have been taken to treat running water, especially on unpaved forest roads and working roads.

FIG. 7 shows an example of a conventional countermeasure. In the countermeasure shown in the figure, a side ditch 1 is provided along the edge of the mountain side M of an unpaved forest road or working road. This side gutter 1 allows running water from the mountain side M to escape to the downstream side, so it helps to prevent the running water from the mountain side M from flowing out onto the road surface R and causing the road surface R to be scoured or eroded. Further, in case there is a large amount of rainfall and the running water cannot be treated by the side gutter 1 alone, a branch gutter 2 extending from the side gutter 1 across the road surface R may be provided. This branch groove 2 allows water flowing on the road surface R and water overflowing from the side gutter 1 to escape to the valley side V of the road edge, so that the water flows down the road surface R downstream of the branch groove 2 and This helps prevent scouring and erosion.

On the other hand, a simple measure is to install weirs diagonally across forest roads and working roads, and use these weirs to dam the running water that flows from the road surface or mountain side, and then direct it toward the valley side. Sometimes. A road surface drainage device for taking this type of measure has been proposed in the prior art (see Patent Document 1). In this method, a two-fold flexible member made of a rubber plate or the like is fixed to a square lumber made of Japanese pine, etc., and the lower end of this flexible member is buried in the ground together with the square lumber. The top of the bi-fold protrudes above the road surface.

In the case where running water is treated using the side gutter 1 or the branch groove 2 as explained with reference to FIG. The problem is that gratings are required to be installed on the side ditches and branch ditches 2 to increase safety, which requires a large amount of cost, and cleaning of the side ditches 1 and branch ditches 2 filled with earth and sand is required as necessary. There is a hassle that has to be done.

On the other hand, in the road drainage device proposed in Patent Document 1, the flexible member made of a rubber plate is bent when the wheels or caterpillars of a working vehicle or heavy machinery pass, and the flexible member is bent after passing. We believe that it has the advantage that it does not interfere with the passage of work vehicles or heavy equipment in order to return to its original shape, does not require large-scale construction work or equipment for installation, and is easy to clean. It will be done.

However, in this road surface drainage device, the lower end of the flexible member is fixed to a square timber and buried underground, so if left unused for a long time, the square timber corrodes and the initial installation condition is damaged. The initial running water treatment effect may be impaired in a relatively short period of time due to the square timbers being broken due to repeated passing by the wheels of heavy machinery, caterpillars, etc. and damaging the initial installation condition. Further, when it is desired to cut the flexible member and install it in a place with a narrow road, there is the inconvenience that it is necessary to cut the square timber together with the flexible member. Another problem is that the square timbers are bulky when transported.

The present invention was developed in view of the above circumstances, and is a device that can be easily installed on forest roads and working roads in the mountains, while maintaining the initial running water treatment effect over a long period of time. The purpose is to provide a road surface water guiding device with excellent durability. In addition, the present invention provides a road surface water guide device that not only makes it easier to carry materials to a construction site, but also allows easy installation on narrow roads without having to cut square timbers, which are troublesome to cut. The purpose is to

The road surface water guide device according to the present invention is a road surface water guide device used to dam running water on the road surface and guide it to the roadside. A horizontally long weir plate made of a rubber plate that is buried in the ground and the rest protrudes from the road surface, and a plurality of reinforcing bars that are held through the weir plate at multiple locations in the longitudinal direction of the underground buried area of this weir plate. .

According to the road surface water guide device with this configuration, the water flowing from the road surface or mountain side of a forest road or working road is dammed by the weir plate, and then guided to the roadside and released, so that On the sides, running water will no longer cause scouring or erosion of the road surface. Therefore, for long road surfaces, by installing weir plates in multiple stages at predetermined intervals, the road surface is prevented from being scoured or eroded by running water flowing over long distances. In addition, since the weir plate is made of a rubber plate, even if wheels or caterpillars of work vehicles or heavy machinery pass by, it will not bend and become an obstruction to traffic, and will return to its original shape after passing, making it easier to carry out work. It does not interfere with the passage of vehicles or heavy equipment.

In particular, in the present invention, the multiple reinforcing bars that are held through the weir plate at multiple locations in the longitudinal direction of the underground area of the weir plate have long-term durability as their own characteristics. As a result, the initial installed state of the weir plate is maintained, and the reinforcing bars do not break due to the passing of wheels or caterpillars of work vehicles or heavy machinery, so the initial water treatment effect is maintained. This will prevent road surface scouring and erosion over a long period of time. Another advantage is that when it is desired to install it in a narrow road location, it is sufficient to simply cut the weir plate, which is made of an easy-to-cut rubber plate.

In the present invention, it is desirable that the reinforcing bars be press-fitted into holes with a diameter smaller than the diameter of the reinforcing bars opened in the weir plate. According to this, reinforcing bars buried underground are less likely to slip out of the weir plate or shift position due to external factors. This also makes it easier to maintain the initial installed state of the weir plate, making it easier for the initial running water treatment effect to be exerted over a long period of time.

In the present invention, it is desirable to adopt a configuration in which the protruding width of the reinforcing bars on both sides of the weir plate is long enough to prevent the weir plate from slipping out of the ground and maintain its self-supporting posture. This also makes it easier to maintain the initial installed state of the weir plate, making it easier for the initial running water treatment effect to be exerted over a long period of time.

In the present invention, a configuration can be adopted in which reinforcing bars with a diameter of 8 mm and a length of 300 mm are used for a weir plate with a height of 200 mm, a width of 3000 mm, and a thickness of 12 mm. Regarding these numerical values, a difference of several millimeters to several dozen millimeters is included as an allowable range. The water guide device having this configuration is suitable for installation on a forest road or a working road with a road width of about 3000 mm or shorter than about 3000 mm. Furthermore, the initial installed state of the weir plate will last for a long time due to the action of the reinforcing bars. In addition, in places where the road width is narrow, it is possible to install the weir plate without any problems by cutting it to match the road width.

In the present invention, it is preferable that the distance between the lower edge of the weir plate and the center of the hole is 30 mm, and the pitch between the holes at multiple locations in the longitudinal direction of the weir plate is set to 200 mm. . Regarding these numerical values, the allowable range also includes a difference of several millimeters to more than ten millimeters. By combining this configuration with a weir plate having a height of 200 mm, a width of 3000 mm, and a thickness of 12 mm, the initial installation state and initial running water treatment effect can be maintained over a long period of time due to the action of the reinforcing bars.

In the present invention, a flange-shaped member may be attached to each of both ends of the reinforcing bar. According to this, the action of the flange-shaped member reliably prevents the reinforcing bars buried underground from coming out of the weir plate.

According to this invention, not only can it be easily installed on forest roads and working roads in the mountains, but also the initial installation state of the weir board and the initial running water treatment effect can be maintained, preventing road surface scouring and erosion for a long time. It will be prevented for a long time. In addition, it can be easily installed in places where the road width is narrow by simply cutting the weir board.

1 is a plan view of a water guiding device 100 according to an embodiment of the present invention, FIG. 2 is a front view of a weir plate 10, FIG. 3 is an enlarged partial perspective view of the weir plate 10 and reinforcing bars 20, and FIG. is an explanatory diagram showing the relationship between the diameter D1 of the hole 11 of the weir plate 10 and the diameter D2 of the reinforcing bar 20, FIG. 5 is an explanatory plan view illustrating the installation state, and FIG. 6 is taken along the line VI-VI in FIG. 5. It is an enlarged sectional view.

As shown in FIG. 1, the running water guiding tool 100 includes a horizontally long weir plate 10, and a plurality of weir plates 10 held in a penetrating state at a plurality of locations in the longitudinal direction (multiple locations in the lateral direction) of the weir plate 10. It is equipped with 20 real reinforcing bars. A flat rubber plate is used for the weir plate 10. The flat rubber plate of the weir plate 10 is preferably a rubber plate reinforced by laminating one or more fiber reinforcing layers (not shown) such as a plain weave structure. Further, the reinforcing bars 20 penetrate the underground region of the weir plate 10.

As shown in FIG. 2, in the vicinity of the lower edge of the weir plate 10, circular holes 11 are formed at a plurality of horizontally arranged positions at equal pitches. As shown in FIG. 4, the diameter D1 of this hole 11 is slightly smaller than the diameter D2 of the reinforcing bar 20. Therefore, the reinforcing bars 20 are press-fitted into the weir plate 10 at the locations where the reinforcing bars 20 penetrate the weir plate 10 .

When transporting the weir plate 10 and the plurality of reinforcing bars 20 of the running water guide tool 100 having the above-described configuration to the construction site of the running water guide tool 100, the required number of weir boards 10... are rolled into a cylindrical shape, and the required number of reinforcing bars are If 20... are bundled and loaded onto a truck or the like and transported, it becomes possible to transport these materials in a compact form. Then, it becomes possible to perform the work of penetrating the reinforcing bars 20 into the holes 11 of the weir plate 10 at the construction site. In this way, the efficiency of transporting materials such as the weir board 10 and the reinforcing bars 20 is improved, and the transport cost is reduced.

The running water guiding tool 100 assembled by passing the reinforcing bars 20 through the holes 11 of the weir plate 10 is constructed by attaching a part of the weir plate 10 including the penetration point of the reinforcing bars 20 and the reinforcing bars 20 to a groove dug into a forest road or a work road. After it is placed in the ground, the trench is backfilled and buried underground, with the remainder protruding from the road surface. The width and depth of the groove dug into the road surface R are determined by taking into consideration the protruding width A of the reinforcing bars from the weir plate 10 (see FIG. 6) and the height H of the weir plate 10 (see FIG. 2). In this case, the weir plate 10 is usually disposed diagonally across the road surface R so that the end of the valley side V of the weir plate 10 is located on the lower side of the road surface R, as shown in FIG. An appropriate inclination angle θ of the weir plate 10 with respect to the width direction of the road surface R is appropriately determined by taking into account the slope of the road surface R, the condition of the road surface R, the amount of water flowing due to rainfall, and the like. For example, it is possible to set θ=15 degrees, and it is desirable to increase the inclination angle θ in places where there is a large amount of water flowing.

When the weir board 10 is buried in the ground, the reinforcing bars 20 protruding to both sides of the weir board 10 are also buried underground, so the reinforcing bars 20 only serve to prevent the weir board 10 from rising or slipping out from the road surface R. In addition, it is also useful for maintaining the independent posture of the weir plate 10. Such an effect of the reinforcing bars 20 is reliably exerted by making the projecting width A of the reinforcing bars 20 on both sides of the weir plate 10 sufficiently long. Furthermore, since the reinforcing bars 20 are press-fitted into the holes 11 of the weir plate 10, it is possible to prevent the reinforcing bars 20 buried underground from shifting relative to the weir plate 10 due to external factors such as vibration. This also ensures that the above-described effect of the reinforcing bars 20 is exerted. In this embodiment, as shown in FIG. 3, male threads 21, 21 are provided at each end of the reinforcing bar 20, and collar-shaped members 30, 30 made of flat washers with female threads are screwed into these male threads 21, 21. It is installed in the condition. By doing so, the reinforcing bars 20 are more reliably prevented from slipping out of the holes 11 of the weir plate 10.

According to the road surface running water guiding device 100 having this configuration, as illustrated in FIG. After being dammed by the road, it is guided along the weir plate 10 as indicated by arrow F to the road edge and released to the valley side V, so that scour and erosion of the road surface R do not occur on the downstream side of the weir plate 10. . Therefore, for a long road surface R, by installing the weir plates 10 in multiple stages at predetermined intervals, the road surface R is prevented from being scoured or eroded by running water flowing over a long distance. Furthermore, as illustrated in FIG. 6, since the weir plate 10 is made of a rubber plate, even if the wheels or caterpillars of a work vehicle or heavy machinery ride on the weir plate 10 and pass, the weir plate 10 is It does not bend as shown by arrows a or b in the direction of travel of vehicles and heavy machinery and become an obstruction to traffic, and returns to its original shape after passing, so it does not obstruct the passage of work vehicles or heavy machinery. do not have.

In particular, since the plurality of reinforcing bars 20 held penetratingly through the weir plate 10 have long-term durability as their own characteristics, the initial installed state of the weir plate 10 can be maintained, and Since the reinforcing bars 20 do not break due to the passing of wheels or caterpillars of work vehicles or heavy equipment, the initial installation condition and running water treatment effect continue to prevent scouring and erosion of the road surface over a long period of time. will be prevented. Further, when it is desired to install it in a place where the road width is narrow, the weir plate 10 made of a rubber plate can be cut to match the road width.

In this embodiment, the height H shown in FIG. 2 is 200 mm, the horizontal length L shown in FIG. 1 is 3000 mm, and the thickness T shown in FIG. 1 is 12 mm. 300mm reinforcing bars 20 are used. When adopting such a weir plate 10 and reinforcing bars 20, it is desirable that the groove width of the trench dug when burying the weir plate 10 underground is about 300 mm and the groove depth is about 100 mm; If the width of the weir plate 10 is about 100 mm, the protruding width of the weir plate 10 from the road surface R will be about 100 mm, and a good running water guiding effect will be exhibited.

The running water guiding device 100 having this configuration is suitable for installation on a forest road or a working road with a road width of about 3000 mm or shorter than about 3000 mm. That is, in places where the road width is about 3000 mm, the weir board 10 can be used as is without cutting, and in places where the road width is narrower than about 3000 mm, the weir board 10 can be used by cutting it to match the road width. can.

Further, the holes 11 provided in the weir plate 10 are arranged so that the distance S from the lower edge of the weir plate 10 to the center of the holes 11 is approximately 30 mm, as shown in FIG. Then, the reinforcing bars 20 are reliably buried underground. Furthermore, the pitch between the holes 11 at a plurality of locations in the longitudinal direction of the weir plate 10 is set to about 200 mm. It has been found that when this is combined with a weir plate 10 with a height of 200 mm, a width of 3000 mm, and a thickness of 12 mm, the initial installation state and initial water treatment effect will be maintained for a long period of time due to the action of the reinforcing bars 20. .

In addition, the dimensions of each part listed above are dimensions as a guideline that are advantageous for improving the usability of the weir plate 10 and suitably exerting the action of the reinforcing bars 20, and are not necessarily limited to the dimensions listed above. It's not a thing. Furthermore, in the above-described embodiment, the case where the water guide device 100 is installed on an unpaved road surface R has been described, but it can be similarly installed in a place where the road surface R is simply paved.
