  The present invention relates to a crossing road gutter and a grating lid mounted thereon, and in particular, a crossing road gutter with improved drainage capacity in a crossing road gutter installed on a road laid with permeable asphalt. And a transverse groove unit of a grating lid used for the same.

2. Description of the Related Art Conventionally, a side groove unit 10 configured as shown in FIGS. 7 to 13 is known as a crossing road side groove provided with a grating lid. 7 and FIG. 9 are perspective views showing the overall configuration of the side groove unit 10 in which the road side groove 20 provided with the grating lid 30 is combined. FIGS. 8 and 10 are perspective views showing the overall configuration of the road side groove 20. FIG. 12 is a perspective view showing the overall configuration of the grating lid 30. FIG.
FIG. 13 is a cross-sectional perspective view showing a state in which rainwater flows from the road with respect to the conventional gutter unit 10. In the drawings, the same symmetrical parts are indicated by the same reference numerals, and the same components or corresponding parts are indicated by the same reference numerals, and redundant description thereof is omitted.
As shown in FIG. 13, the gutter unit 10 is configured such that, for example, one or more grating lids 30 are placed on the road gutter 20 serving as a base. Normally, the installation of the road side groove 20 on the road is performed by digging a deeper and deeper groove than the outer shape of the road side groove 20, and then laying a plurality of road side grooves 20 on the foundation concrete. . When installed, the road side grooves 20 are placed so that the end faces 19 come into contact with each other, and the U-shaped joint portion 12 provided on the inner side of the end face 19 over the contact face is solidified with mortar or the like. Complete.

As shown in FIG. 10, the conventional structure of the road side groove 20 for crossing has the top surface as the top end portion 113, and the lid receiving portion 14 has a lower step than the top end portion 113, and the lid receiving portion for receiving the grating lid 30. It is formed as a part 14.
Then, as shown in FIG. 9, the grating lids 30 having leg members 31 formed with substantially the same width are formed and placed on both the lid receiving portions 14 facing each other inside the road side groove 20. The In this state, the height of the top end portion 113 of the road side groove 20 is substantially flush with the upper surface of the grating lid 30, and the side groove unit 10 is configured.
However, the top end portion 113 of the road side groove 20 is lost due to vehicle traffic or the passage of time, or the leg member 31 of the grating lid 30 is distorted to generate noise, and the top end portion 113 and the cover receiving portion of the road side groove 20 are generated. 14 was damaged.
Therefore, as shown in FIGS. 7 and 8, the steel frame is often reinforced.
As shown in FIG. 8, the structure of the conventional crossing road side groove 20 in which the lid receiving portion is reinforced with an iron frame is an iron frame so that the concrete portion is not lost at the top end portion 113 on the upper surface. 15 is provided, and the lid receiving portion 14 is formed with a step lower than the top end portion 113, and an L-shaped iron receiving frame 16 is provided to form the lid receiving portion 14.
Further, as shown in FIG. 7, the grating lids 30 having substantially the same width are molded and placed in the opposite lid receiving portions 14 inside the road side groove 20. In this state, the height of the iron frame 15 covering the top of the top end portion 113 of the road side groove 20 is substantially the same plane as the upper surface of the grating lid 30, and the side groove unit 10 is configured.
Then, as shown in FIG. 13, the gutter unit 10 was laid so that the height of the gutter unit 10 was substantially flush with the height of the upper surface of the asphalt road, and the construction was completed.

As shown in FIGS. 9 to 13, the conventional road side groove 20 is provided with a lid receiving portion 14 having a width of about 50 mm (average of JIS standards, etc.) inside as a portion for receiving the grating lid 30. The lid 30 has a structure in which the weight of the vehicle is concentrated on the lid receiving portion 14 of the road side groove 20 via the leg member 31 of the grating lid 30 from above.
With the passage of time, the top end 113 of the road side groove 20 is damaged due to chipping or cracking, and at the same time, the grating lid and the leg member 31 are distorted to damage the lid receiving part 14 of the road side groove 20 and noise. Was generated.
As a method for solving such damages such as defects and cracks, as shown in FIGS. 7 to 8, the steel frame 15 is reinforced with an iron frame, and the iron frame 15 is covered on the top end portion 113 of the road side groove 20, and the lid is also covered. An L-shaped iron receiving frame 16 is provided in the receiving portion 14 and the grating lid 30 is fixed with bolts 17 and nuts 18 to form the side groove unit 10 shown in FIG.
As a result, the road side groove 20 has been strengthened, but as the vehicle (including 20-ton vehicles) goes back and forth many times, the nut of the bolt part loosens with the passage of time, and the ironing frame of the grating lid 30 and the road side groove 20 16, a high-pitched noise caused by iron and iron is generated, which harms the living environment and damages the bolt part. In addition, the cost of reinforcing parts by the iron frame 15 and the iron receiving frame 16 is increased. There was an economic burden on the consumer side.
Further, on a rainy day, the iron frame 15 of the road side groove 20 becomes slippery and a bicycle or a pedestrian may fall down. Therefore, a convex portion for preventing the upper part of the iron frame 15 and the grating lid 30 from slipping. Etc., and the manufacturing cost was increased.

As shown in FIG. 13, in recent years, a permeable asphalt 50 has been laid on the road foundation concrete 51. This improves drainage of the road when it rains, and rainwater is applied to the asphalt surface by the permeability. It is laid more and more because it has the advantage of not accumulating, noise reduction, and improving the forward visibility of the vehicle driver at night.
However, even if the permeable asphalt 50 is laid along with the laying of the conventional gutter unit 10 as shown in the rainwater flowing into the road gutter 20 from the road shown in FIG. It permeates and remains in the permeable asphalt 50 and cannot flow into the road side groove 20 in this state.
The rainwater that has penetrated into the permeable asphalt 50 is prevented from flowing into the road side groove 20 by the top end 113 of the road side groove 20 or the steel frame 15, and the rainwater floats on the surface of the permeable asphalt 50. Thus, after reaching the surface of the water permeable asphalt 50, the vehicle passes over the top end portion 113 and the iron frame 15 of the road side groove 20 and flows into the road side groove 20, and the effect of rainwater drainage is reduced by half.
In addition, when the amount of traffic of the vehicle passing over the road side groove 20 is large, the road side groove 20 does not sink, but the asphalt portion around the road side groove 20 sinks underground, and the vehicle traffic portion becomes a tire groove, which becomes a rut. As a result, it became a puddle, rainwater splashed by vehicle traffic, and pedestrians were often damaged by rainwater.
Furthermore, if rainwater floating on the surface of the water permeable asphalt 50 does not flow into the road side groove 20 and is prevented from draining from the top end 113 of the road side groove 20 or the steel frame 15, the rainwater will flow downward. If there is a residential area in the lower place, the surrounding area will be flooded, and it will develop into damage such as flooding under the floor of the house. Three causes of damage occurred. In recent years, as extreme weather continues due to global warming, floods caused by torrential rains are increasing in various parts of Japan, and when the amount of rainfall exceeds the allowable level, rainwater flows into the road gutter 20. Without it, the rainwater of that amount included the danger of an unseen disaster, and the economic burden for reconstruction was large.

  In order to solve these problems, the present invention eliminates the top end 113 and the wall of the steel frame 15 which hinder the inflow of rainwater into the drainage channel of the conventional gutter unit 10, and combines the ceiling of the concrete portion. By eliminating the iron frame and iron receiving frame used to prevent the end 113 and the lid receiving part 14 from being lost, the top end part and the lid receiving part are made the same height to realize a wide receiving width of the lid receiving part. The transverse side groove 2 according to claim 1 is increased in strength, and the grating lid according to claim 2 is bolted thereon to further increase the strength and eliminate the generation of noise, and at the same time, on a permeable asphalt road The infiltrated rainwater efficiently flows into the transverse gutter unit of the present invention to prevent flood damage, and in addition, even if the asphalt road around the transverse gutter unit is recessed, the transverse gutter unit Let rainwater flow in It is possible to provide an easy-to-walk road where rainwater is not applied to pedestrians even on rainy days, and cost reduction can be achieved without using an iron frame and iron receiving frame as in the case of the conventional gutter unit 10. An object of the present invention is to provide a transverse gutter unit and a side drainage type grating lid that have an integrated structure that can reduce the burden on the consumer and can be expected to have an economic effect.

In the transverse groove 2 according to claim 1, bolts 7 for restraining the movement of the side drainage type grating lid 3 are arranged at several places on the top end portions 13 facing the upper part of the transverse groove 2, and The transversal side groove unit 1 is formed by placing the grating lid 3 and fixing it with a nut 8 so as to be integrated.
The lateral drainage type grating lid 3 according to claim 2 is provided on both side surfaces facing each other with a plate 4 having a plurality of drainage holes 5, and is fixed to the top end portion of the transverse type side groove 2 by bolts and nuts. The drainage of the drainage of the plate 4 of the grating lid 3 in a direction perpendicular to the connecting direction of the transverse lateral gutter unit 1 is performed as a grating lid for rainwater drainage of the transverse gutter unit 1. It is a side drainage type grating lid which has a structure which passes through the hole 5 and then passes through the gap between the flat plate plates of the grating lid 3 and flows into the transverse side groove 2 of claim 1.

The transverse-type side groove unit 1 in the case of carrying out the present invention is constituted integrally by the transverse-type side groove 2 and one or more side drainage type grating lids 3.
Further, the bolt 7 for restraining the movement of the grating lid provided at the top end portion 13 at the upper part of the transverse groove 2 is fitted with the position of the detent plate 6 provided substantially at the lower part of the grating lid 3. Any nut may be used as long as it is tightened with a nut 8 and the relative movement between the transverse groove 2 and the grating lid is firmly restricted.

  Then, rainwater outside the side drainage type grating lid 3 passes through the drain holes 5 of the plate 4 of the grating lid 3 in the direction perpendicular to the length direction connected to the end face 9 of the transverse groove 2 and The structure that passes through the gap between the flat steel plate plates of the grating lid 3 and flows into the transverse side groove 2 is such that the asphalt agglomerates are not clogged when permeable asphalt is laid. Any structure that allows rainwater to pass from the inside to the inside. Moreover, it should just be a grade which an asphalt granule does not enter into the grating lid | cover 3, and should just be a structure which can let rain water pass. This side drainage type grating lid 3 is used when the rainwater or the like that has fallen on the road penetrates into the permeable asphalt laid on the road and flows into the transverse side gutter 2. This is for passing through the drain hole 5 of the plate 4 of the lid 3 and entering the inside of the transverse side groove 2.

  And, the structure in which rain water outside the side drainage type grating lid 3 flows through the grating lid 3 and flows into the interior of the transverse mold side groove 2 in a direction perpendicular to the connecting length direction of the transverse mold side groove 2. Any shape that can pass rainwater stably from the side of the grating lid 3 can be used regardless of whether it is constructed with water-permeable asphalt or has been used for many years.

In the transverse type side groove unit 1, a detent plate 6 that restrains the movement of the side drainage type grating lid 3 is fitted to a bolt 7 and the side drainage type grating lid 3 is tightened with a nut 8 and integrated. The grating lid 3 is fixed to the top end portion 13 of the transverse side groove 2 by screwing the nut 8 to the bolt 7.
If the bolt 7 for restraining the movement of the side drainage type grating cover 3 provided at the top end 13 of the transverse groove 2 is cylindrical and has a substantially conical tip, the grating cover 3 It is easy to insert the detent plate 6 provided substantially at the bottom of the bolt 7.

  The lateral drainage type grating lid 3 according to claim 2 has several flat and long flat steel plates that are rectangular in cross section and are vertically spaced at equal intervals. From the upper part of the flat steel plate, long and thin bar bars having a round or polygonal cross section are provided. Crossed at equal intervals and welded or welded to form a grating-like grating, and further, a flat iron plate plate 4 having a plurality of drain holes 5 is provided between the flat plate iron plates of the grating. As a plate-like side drainage type grating lid 3 which is welded as a plate portion on both side surfaces on the side to be a grid, rainwater outside the grating lid 3 passes through the plurality of drain holes 5 of the plate 4. In addition, the structure is intended to pass through the gap between the flat plate-like iron plates of the grating lid 3 and to flow into the drainage channel of the transverse groove 2 of claim 1.

  As the shape and size of the drainage hole 5 of the plate 4 of the side drainage type grating lid 3, the shape of a round hole or an elliptical hole having such a size that the asphalt agglomerates do not enter is preferable. Other shapes of drainage holes can be reverse U-shaped holes and square holes, but the side drainage type grating lid 3 can be used even if water-permeable asphalt agglomerates enter or become clogged. For example, an inverted U-shaped slit shape or an inverted V-shaped shape that opens downward is not applied to the permeable asphalt side when the bolt 7 is lifted off. The specific dimensions of the diameter and width of the drain holes 5 are such that they are not easily clogged by foreign matter such as small dust or dust, and the maximum value is about 20 mm or less in consideration of asphalt agglomerates and fluidity thereof. It is desirable to apply.

A side drainage type grating lid 3 provided with a detent plate 6 for restraining relative movement with the transverse type side groove 2 is restricted in movement by the detent plate 6 and extends in the length direction of the transverse type side groove 2. Rainwater outside the side drainage type grating lid 3 passes through the drain holes 5 of the plate 4 of the side surface drainage type grating lid 3 in a direction perpendicular to the side and flows into the side drainage type grating lid 3. Then, it is made to flow in the drainage channel of the transverse type side groove 2.
Here, the transverse type side groove 2 in which the bolt 7 for restricting the movement of the side drainage type grating lid 3 is arranged is restricted by the bolt 7 and is connected to the connecting length direction of the transverse type side groove 2. Rainwater outside the side drainage type grating lid 3 passes through the drain holes 5 of the plate 4 of the side drainage type grating lid 3 in the direction perpendicular to the gap between the flat steel plates of the grating lid 3. It can be set as the structure of the side surface drainage type grating lid 3 which flows into the drainage channel of the transverse type side groove 2.
Then, in a direction perpendicular to the length direction of the transverse groove 2, rainwater outside the side drainage type grating lid 3 passes through the drain holes 5 of the plate 4 of the grating lid, and the side drainage type grating. The structure that flows into the lid 3 and the transverse lateral groove 2 is such that when permeable asphalt is laid, the permeable asphalt agglomerates are not clogged, and the water is stably stabilized from the side toward the inside. Any configuration can be used as long as it can pass through.
Further, the steel plate 4 with drain holes is preferably made of strong steel, but any material may be used as long as it has the same strength, and plastic may be used instead.

  The transverse-type side groove unit 1 according to claim 1 is constructed in such a manner that the transverse-type side groove 2 on which the side drainage type grating lid 3 is placed is constructed on a road where water-permeable asphalt is laid. The permeated rainwater passes through the drain holes 5 of the side plate 4 of the side drainage type grating lid 3 in a direction perpendicular to the length direction of the transverse side groove 2 and continues to the flat plate of the side drainage type grating lid 3. It is a structure that passes through the gap between them and efficiently flows into the drainage channel of the transverse side gutter 2 and drains rainwater that stops in the permeable asphalt, thereby preventing flooding.

  Bolts 7 for restraining the movement of the side drainage type grating cover 3 are disposed at the top end 13 of the transverse groove 2. The grating cover 3 is screwed with a nut 8 and firmly fixed to move. Therefore, the grating lid 3 is not displaced or rattled with respect to the transverse groove 2 and noise can be prevented.

  In addition, the transverse side groove 2 is widened by tightening the side drainage type grating lid 3 with bolts and nuts to firmly fix the opening side of the transverse side groove 2 by the weight of the vehicle or the like. The structure increases the strength against stress that shrinks or shrinks. Therefore, even if a large force is applied from the upper surface of the side drainage type grating lid 3, the transverse side groove 2 can be received by the lid receiving portion by the bolt fixing and the wide top end 13 and the opening side of the transverse side groove 2 is opened. No external force is generated in the direction in which the width of the transverse groove is expanded, and the transverse side groove 2 is not cracked or damaged.

The side drainage type grating lid according to claim 2 is provided with a bolt 7 for restraining the movement of the grating lid 3 on the top end portion 13 of the transverse type side groove 2. The detent plate 6 that restricts the movement of the lateral drainage type grating lid 3 with respect to the transverse groove 2 prevents the lateral drainage grating lid 3 from being displaced, and resists stress that widens or shrinks the opening side of the transverse groove 2. This increases the strength.
Even if the weight of the vehicle or the like is added from the upper surface of the side drainage type grating cover 3, the thickness of the entire top end portion 13 of the transverse type side groove 2 located at the lower part of the grating lid 3 and the thickness of the entire transverse type side groove 2 It can be caught, can disperse weight and will not be damaged.

  Further, the rainwater that has penetrated into the water-permeable asphalt 50 passes through the drain holes 5 of the side plate 4 of the side drainage type grating lid 3 in the direction perpendicular to the length direction of the transverse side gutter 2 and continues to the side surface. The structure that passes through the gap between the flat steel plates of the drainage type grating lid 3 and flows into the drainage channel of the transverse side gutter 2, drains rainwater that remains in the permeable asphalt 50, efficiently drains and flows into the structure. When the water-permeable asphalt 50 is laid, the water-permeable asphalt agglomerates can pass through the drain holes 5 of the braids 4 on the side surfaces of the water-permeable asphalt agglomerates and can stably pass rainwater inward.

  Further, when the transverse gutter unit 1 of the present invention is laid on a road, only the side drainage type grating cover 3 appears on the road surface, and a flat iron plate plate having a non-slip protrusion (conventional technology) is attached to the grating cover 3. In addition, it can directly contact the water-permeable asphalt 50 of the grating lid 3, and its overall width is widened to provide a slip prevention effect, thereby reducing the risk of rainy days. In addition, it is not necessary to use the iron frame 15 or the iron receiving frame 16 used at the uppermost portion of the conventional gutter unit 10, which greatly reduces the manufacturing cost.

  In addition, as shown in FIGS. 1, 7, and 9, when the strength of the transverse side groove unit 1 of the present invention is compared with that of the conventional side groove unit 10, a large weight such as a truck is formed from the upper surface of the side drainage type grating lid 3. However, the transverse side groove 2 has a top end portion 13 that is a lid receiving portion that is twice or more wide than the lid receiving portion 14 of the conventional road side groove 20 and receives the weight to receive the weight. Are distributed evenly and the top end portion 13 of the transverse groove 2 does not appear on the road surface by the grating lid 3, so that the concrete portion is not damaged or damaged, and the transverse groove 2 and the side surface Since the drainage type grating lid 3 is bolted to prevent rattling, the product life of side grooves and gratings can be extended.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the following drawings, in the embodiment, the symmetrical parts are denoted by the same reference numerals, and the same or similar parts after the second embodiment are denoted by the same reference numerals. The overlapping description is omitted.

FIG. 1 is a perspective view showing the overall configuration of a transverse gutter unit 1 according to a first embodiment of the present invention. FIG. 2 is a perspective view showing the overall configuration of the transverse side groove 2 in which the side drainage type grating lid 3 is fixed to the upper part and integrated. FIG. 3 is a perspective view showing the entire configuration of the side drainage type grating lid 3 which is fixed to the upper part of the transverse type side groove 2 and integrated. FIG. 4 is a plan view showing a steel plate 4 with drainage holes that is welded to the side surface of the side drainage type grating lid 3 and enables side drainage. FIG. 5 is a plan view of the side drainage type grating lid 3 as seen from above. FIG. 6 is a construction example diagram showing an example of the transverse gutter unit 1 and the drainage of rainwater.
As shown in the drawing, in the embodiment of the present invention, one or more side drainage type grating lids 3 are placed on the transverse side groove 2 to form a transverse type side groove unit 1, and one or more transverse type side groove units 1. Are arranged and constructed on the road.

  As shown in FIG. 6, for the installation of the transverse gutter unit 1 on the road, a slightly deeper and deeper groove than the outer shape of the transverse gutter unit 2 is dug in the same manner as the construction of the conventional gutter unit 10 shown in FIG. After the concrete as the foundation is struck, the transverse die side groove 2 is placed thereon, and is continuously arranged so that the end faces 9 of the transverse die side groove 2 are in contact with each other. The transverse groove 2 is connected by hardening the portion 11 with mortar or the like.

As shown in FIG. 2, a bolt 7 is embedded in the top end 13 of the transverse side groove 2, and in order to correspond to this bolt 7, as shown in FIGS. 3 is provided with a detent plate 6.
Since the transverse type side groove 2 and the side drainage type grating lid 3 are fixed, the moving resistance against the direction in which the transverse type side groove 2 expands to the road side or shrinks to the inner side of the side groove becomes strong. Even if a large weight is applied from the upper surface of the lid 3, the transverse side groove 2 receives the force widely on the entire surface of the top end portion 13 so that the weight is dispersed, and the transverse side groove 2 is less likely to be damaged. This is effective in preventing cracks in the transverse groove 2.
Then, as shown in FIG. 1, the side drainage type grating lid 3 is placed on the top end portion 13 of the transverse type side groove 2, and the nut 8 is screwed and fixed to the bolt 7 to restrain movement. The rattling is prevented to prevent the grating lid 3 from falling off and to prevent rattling noise.
In this state, as shown in FIG. 6, the upper surface of the side drainage type grating lid 3 placed on the top end portion 13 of the transverse type side groove 2 and the upper surface of the water permeable asphalt 50 are substantially flush with each other.

Next, the configuration of the side drainage type grating lid 3 in the embodiment of the present invention will be described.
FIG. 3 is a perspective view showing the entire configuration of the side drainage type grating lid 3 which is fixed to the upper part of the transverse type side groove 2 and integrated. FIG. 4 is a plan view showing an iron plate plate 4 with drainage holes that enables side drainage of the side drainage type grating lid 3. FIG. 5 is a plan view of the side drainage type grating lid 3 as seen from above.

As shown in FIGS. 3 and 4, in the steel plate 4 (A), (B) with drainage holes installed on the side surface of the side drainage type grating lid 3 by welding or the like, In the perpendicular direction, a drain hole 5 of a round hole, an elliptical hole, or a square hole is provided as a water passage so that rainwater passes toward the inside thereof. In addition, the shape of the drain hole used as the water passage may be an inverted U-shaped slit shape, a triangular shape, or a bowl shape.
The drainage hole-attached plate 4 (A) of the side drainage type grating lid 3 has a round hole which is a drainage hole on the top and a rectangular hole or an elliptical hole formed on the lower side thereof.
In addition, the steel plate 4 (B) with drainage holes has a size smaller than that of the flat steel plate, and the drainage holes form rectangular holes, elliptical holes, round holes, etc. The plate 4 (B) is installed so that the height of the upper part is substantially the same. In the case of the plate 4 (B), a gap between the flat iron plate and the flat iron plate is formed below, and this portion also has a function as a drainage hole, and is seen from the front in which the plate 4 (B) and the flat iron plate are combined. The shape of the case is a bowl shape.
The position of the drainage hole 5 is preferably provided approximately 5 to 10 mm below the uppermost part of the steel plate 4 (A) and (B) with drainage hole. If the asphalt road settles underground, the drainage hole 5 However, depending on the height of the drain hole 5, the rainwater drains well.
The diameter and width of the drain hole 5 are, for example, about 3 to 18 mm so that rainwater can pass through and the asphalt agglomerates laid on the road do not enter or become clogged. It is desirable from the result confirmed experimentally.

As shown in FIGS. 4 and 5, a detent plate 6 that is screwed into the bolt 7 of the top end portion 13 of the transverse side groove 2 is installed at the lower part of the side drainage type grating lid 3.
Further, as shown in FIGS. 7 and 9, the width of the conventional grating lid 30 received by the lid receiving portion 14 of the road side groove 20 of the conventional side groove unit 10 is about 50 mm. As shown in FIG. The width of receiving the lateral drainage type grating cover 3 at the top end 13 of the transverse type side groove 2 of the horizontal type side groove unit 1 is about 100 mm on average, and the wide range of the grating cover 3 is received. In addition to being approximately twice as wide, in addition to being able to disperse the weight in a wide range, it maintains sufficient strength and greatly improves the durability life of the transverse side groove 2, thereby reducing costs.

Next, FIG. 6 shows a case where the transverse gutter unit 1 of the present embodiment is installed on the road on which the water-permeable asphalt 50 is laid, and the conventional gutter unit 10 is installed on the road. This will be described in comparison with FIG.
FIG. 6 is a partial cross-sectional perspective view showing a flowing state of rainwater from the road with respect to the transverse gutter unit 1. Similarly, FIG. 13 is a partial cross-sectional perspective view showing the rainwater flowing in from the road with respect to the conventional gutter unit 10.

  In FIG. 13, as described above, the construction situation of the conventional gutter unit 10 described above, the rain that has fallen on the road surface once penetrates into the permeable asphalt 50. However, even if the rainwater that has penetrated into the water permeable asphalt 50 is blocked by the road foundation concrete 51 and moves to the side groove unit 10 side through the water permeable asphalt 50, the concrete portion of the top end portion 113 of the road side groove 20. Alternatively, since the steel frame 15 becomes a wall and rainwater cannot flow into the drainage channel of the road side groove 20, the rainwater reaches the surface of the permeable asphalt 50 and overflows, and then the top end 113 of the road side groove 20 or the iron frame. As a result, the function of water-permeable asphalt could not be demonstrated. It is well known that the more rainwater overflows on the road surface, the higher the slip rate of the vehicle and the higher the risk of causing an accident.

On the other hand, in the embodiment of the present invention shown in FIG. 6, the rain that has fallen on the road surface also penetrates into the permeable asphalt 50 and is prevented from penetrating into the lower road foundation concrete layer 51. The inside of the water-permeable asphalt 50 moves to the transverse type side groove unit 1 side. Then, rainwater passes through the drainage holes 5 of the plate 4 installed on the side surface of the side drainage type grating lid 3 fixed to the top end 13 of the transverse groove 2, and the flat steel plates of the grating lid 3 are connected to each other. And then drain and flow efficiently into the drainage channel of the transverse gutter 2.
Therefore, even if there is a large amount of rainfall due to heavy rain, the function of the grating lid 3 causes rainwater to flow into the drainage channel of the transverse lateral gutter 2, and rainwater does not stop in the permeable asphalt 50. Rainwater does not float on the surface of the permeable asphalt 50.
Even if the precipitation due to local heavy rain exceeds the allowable amount and exceeds the allowable amount of side drainage of the grating lid 3, the grating lid 3 is in close contact with the permeable asphalt 50. As a result, the drainage is efficiently drained from the upper surface, and the side drainage type grating lid 3 can perform the drainage process faster than the conventional grating 30.
As a result, when the transverse gutter unit 1 is installed on the road and the permeable asphalt 50 is laid, the drainage is good even when a large amount of rain falls, and the rainwater floats on the surface of the permeable asphalt 50. In addition, the damage caused by splashes and difficulty in walking are reduced, and the light reflection caused by rainwater is reduced during vehicle traffic at night, which improves the driver's forward visibility and safety. It helps to prevent flooding by flowing quickly to the gutter drainage channel.

FIG. 4 is an explanatory view of a water passage serving as a drain hole 5 provided in the plate 4 that is fixed to the side surface of the side drainage type grating lid 3 by welding or the like.
The size of each drainage hole 5 of the steel plate 4 with drainage holes of the side drainage type grating lid 3 is clogged with the permeable asphalt 50 after the grating lid 3 is laid on the road together with the transverse side gutter 2. It is set to a shape and dimensions that do not occur.
Moreover, the shape of the drain hole 5 does not necessarily require the shape shown in FIG. 4, and has a shape and size that does not allow the granularity of water-permeable asphalt 50 laid on the road to enter or become clogged. Any setting may be used.
The drainage hole-attached plate 4 (A) of the side drainage type grating lid 3 is formed by forming a rectangular hole or an elliptical hole with the round hole as the drainage hole facing up.
In addition, the plate 4 (B) with drainage holes has a dimension smaller than that of the flat steel plate, and the drainage hole forms a rectangular hole or an elliptical hole. The plate 4 (B) is installed so as to be substantially the same. In this case, a gap between the flat iron plate and the flat iron plate is formed below the plate 4 (B), and this portion also has a function as a drainage hole, as seen from the side surface combining the plate 4 (B) and the flat iron plate. In the case, it becomes a bowl shape.
The location of the drainage hole is desirably provided approximately 5 to 10 mm below the uppermost part of the steel plate 4 with the drainage hole. If the asphalt road settles underground, the drainage hole 5 may be visible. Depending on the height of the hole 5, the rainwater drains well.
The diameter and width of the drain hole 5 are, for example, about 3 to 18 mm so that rainwater can pass through and the asphalt agglomerates laid on the road do not enter or become clogged. It is desirable from the result confirmed experimentally.
In particular, the plate 4 (B) can be easily lifted when it is lifted in the vertical direction even when a granular mass of the water-permeable asphalt 50 enters.
In this way, the drainage holes 5 provided in the side drainage type grating lid 3 are arranged such that external rainwater passes through the drainage holes 5 of the plate 4 installed in the side drainage type grating lid 3 and continues to the side drainage type grating lid 3. What is necessary is just the structure used as the transverse type side groove unit 1 which passes through the clearance gap between flat steel plates and flows into the inside of the transverse type side groove 2.
