Description

  The present invention relates to a side groove cover for a water-permeable paved road, which is used by being embedded in a water-permeable pavement formed of water-permeable asphalt or the like, in order to improve drainage of a road surface such as a road, and the side groove cover It is related with the manufacturing method.

  Conventionally, a side groove was provided on the shoulder of the water-permeable paved road, and a side groove cover was attached to the side groove. And rainwater that has flowed on the road surface is drained from the water passage hole on the surface of the side groove cover exposed on the road surface to the inside of the side groove, or rainwater that has penetrated from the road surface is passed through the water hole on the side surface of the side groove. Drained into the gutter.

  However, since the side groove cover is exposed from the surface of the road surface, there are problems that the aesthetic appearance of the road surface is impaired and the side groove cover is damaged by an external force of a vehicle or the like that passes. Furthermore, there has been a problem that the gutter lid is removed and stolen.

  Therefore, in the side groove cover 3 of Patent Document 1 (hereinafter, the reference numeral in the specification of Patent Document 1 is attached), the side groove cover 3 itself is embedded in the water pavement to solve these problems. . This side groove cover 3 is composed of two connecting rods as flexible connecting members in a parallel state in which several angle-shaped members 30 (angle-shaped steel) having corners at the tops are held in a gap S serving as a water passage 31. 32 is connected.

  And, the reason why the several angle-shaped members 30 are arranged in a parallel state in which the gap S serving as the water inlet 31 is maintained is to prevent the side groove side water-permeable surface layer 4 from falling into the inside of the side groove, The gap S is also set to about 5 mm in consideration of this. In addition, several angle-shaped members 30 are connected in parallel by two connecting rods 32 as flexible connecting members because both end portions of each angle-shaped material 30 are connected to lid receiving steps (mounting parts) of side grooves. This is because the side groove cover 3 is mounted without looseness by being placed so as to become familiar with the surface) 25.

  However, in order to prevent the side groove side water-permeable surface layer 4 from falling into the inside of the side groove, the interval between the adjacent chevron mold materials 30 is kept to some extent (about 5 mm), and further, the interval is reduced in the lateral width direction ( In the direction crossing the gutter). Therefore, in patent document 1, there are restrictions on the shape and interval of the chevron shaped material 30, and the degree of freedom in designing the side groove cover 3 is low.

  Further, the side groove lid 3 has the lower end side of the chevron die 30 placed directly on the lid receiving step portion 25 of the side groove. Since the side groove side water-permeable surface layer 4 covers the side groove cover 3, the side groove lid receiving step 25 is added to the weight of the side groove side water-permeable surface layer 4 in addition to the weight of the vehicle traveling on the road surface. It takes a fairly heavy load. Therefore, there is a possibility that the surface of the lid receiving step portion 25 of the side groove, in particular, the portion that is in contact with the chevron shaped material 30 is gradually damaged by this load and becomes uneven.

  Then, the position and posture of each chevron mold member 30 placed on the surface of the lid receiving stepped portion 25 that is uneven is gradually shifted from the correct state at the time of construction, and as a result, it flows into the periphery of the chevron mold member 30. A gap is generated between the side groove side water-permeable surface layer 4 that has been solidified and each chevron 30. And the clearance gap causes the side groove side water-permeable surface layer 4 to crack or break.

  Therefore, in view of the above problems, the present invention has a higher degree of design freedom than the prior art, and a side groove cover for a water-permeable pavement that can reduce damage to a mounting surface on which the side groove cover is placed, and the side groove cover. It aims at providing the manufacturing method of.

  The side groove cover for a water-permeable pavement according to the present invention is a side groove cover for a water-permeable pavement that is placed on the mounting surfaces on both sides of the opening of the side groove and is embedded in the water-permeable pavement along with the side groove. A lateral plate that covers the opening of the lateral groove and can be placed on the placement surfaces on both sides, and a base plate provided with water holes, and the placement plates on the both sides via the base plate A reinforcing member having a length that can be placed is mounted on the base plate in the lateral width direction.

  According to the above feature, since the reinforcing member is installed on the mounting surface of the side groove via the base plate, the external force received by the reinforcing member does not act directly on the mounting surface. Therefore, damage to the surface of the placement surface can be reduced.

  Next, in the lateral groove cover for a water-permeable pavement according to the present invention, the base plate is provided with a fitting groove extending in the lateral width direction, and an end of the reinforcing member is fitted into the fitting groove. It is characterized by that.

  According to the above feature, the fitting groove can be used as a mark when the reinforcing member is disposed on the base plate, and the reinforcing member is not easily displaced from the base plate.

  Next, the manufacturing method of the side groove cover for the water-permeable pavement of the present invention is the water-permeable pavement placed on the mounting surface on both sides of the opening of the side groove and embedded in the water-permeable pavement along with the side groove.

It is characterized by comprising.

  According to the above feature, the water-permeable pavement material is formed by forming a “base plate that covers the opening of the side groove and can be placed on the placement surfaces on both sides of the side groove and has a water passage hole”. It is not necessary to consider the problem of falling into the side groove, and it is freed from restrictions on the shape and spacing of the reinforcing member in Patent Document 1. Furthermore, even the condition that “a reinforcing member is formed on the mounting surface on both sides so that it can be placed via the base plate, and the reinforcing member is mounted on the base plate in the lateral width direction” can be observed. For example, the function of the side gutter lid (the ability to withstand the weight of water-permeable paved roads and vehicles, and the function of draining rainwater etc. into the side gutter) can be fully exhibited, and the shape and spacing of the reinforcing member can be reduced under these conditions. Since it can be determined freely, the degree of freedom in designing the side groove cover is very high.

  Next, in the method for producing a side groove cover for a water-permeable pavement according to the present invention, the step of attaching the reinforcing member forms a fitting groove extending in the lateral width direction on the base plate, The end of the reinforcing member is fitted and attached.

100 Side groove lid 110 Base plate 113 Water flow hole 120 Reinforcement member 200 Side groove 210 Opening 220 Mounting surface R2 Water-permeable pavement

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

  FIG. 1 shows an example of how the lateral groove cover 100 of the present invention is used. As shown in FIGS. 1A and 1B, the side groove cover 100 is placed so as to cover the opening 210 of the side groove 200 embedded in the base layer R1. The side groove cover 100 includes a base plate 110 and a reinforcing member 120 attached on the base plate 110 and fixed by welding or the like. Since the lateral width L 1 of the base plate 110 is wider than the lateral width L 2 of the opening 210, the end portions 111 on both sides of the base plate 110 can be placed on the flat placement surfaces 220 on both sides of the opening 210. Further, since the lateral width L3 of the reinforcing member 120 is wider than the lateral width L2 of the opening 210, the end portions 121 on both sides of the reinforcing member 120 are respectively placed on the mounting surfaces 220 on both sides via the base plate 110. Can be placed.

  And in the state which the side groove cover 100 has covered the opening part 210 of the mounting surface 220, water-permeable pavement material (water-permeable asphalt etc.) is poured over the side groove cover 100 and the side groove 200, and it is to FIG.1 (c). As shown, a water-permeable pavement R2 is formed. As shown in FIG.1 (c), since the side groove cover 100 is embed | buried inside the water-permeable paved road R2, the beauty | look of a road surface is not impaired. Further, since the vehicle or the like does not pass directly over the side groove cover 100, there is no possibility that the side groove cover 100 is damaged, and there is no possibility that the side groove cover 100 is removed and stolen.

  In addition, since the reinforcing member 120 has a mountain shape (see FIG. 2) and the water-permeable pavement material flows into the surface of the mountain shape, the adhesion between the reinforcing member 120 and the water-permeable pavement material is improved. And since the water flow hole 113 is located between these reinforcement members 120, the rainwater etc. which permeate | transmitted the water-permeable pavement R2 smoothly flow along the inclined surface of the reinforcement member 120. It flows to 113 and is drained to a lower side groove. Moreover, since the L-shaped member P fixed to the back surface of the base plate 110 is locked to the inner side surface of the opening 210, it is possible to prevent the side groove cover 100 from being displaced. Instead of the L-shaped member P, anchor bolts are passed through the four corners of the base plate 110, and the tip of the anchor bolt is fixed inside the mounting surface 220, thereby preventing the side groove cover 100 from being displaced. May be.

  Next, a method for manufacturing the side groove cover 100 shown in FIG. 1 will be described with reference to FIG.

  First, as shown in FIG. 2A, a flat metal plate is cut so as to have a lateral width L1 to form a base plate 110. Since the lateral width L1 of the base plate 110 is wider than the lateral width L2 of the opening 210, the opening 210 can be reliably covered. The vertical width L4 of the base plate 110 can be arbitrarily determined, but it is preferable to determine the length so that the completed side groove cover 100 can be conveyed without difficulty.

  Next, as shown in FIG. 2B, a plurality of linear fitting grooves 112 extending in the lateral width direction of the side groove cover 100 are formed in parallel. As a forming method, the fitting groove 112 may be formed by laser processing or by cutting with a metal blade or the like. The width and depth of the fitting groove 112 are set to such a width and depth that the end 121 of the reinforcing member 120 can be fitted. The length of the fitting groove 112 is set to be equal to or greater than the lateral width L3 of the end portion 121 so that the fitting groove 112 can be fitted over the entire length of the end portion 121 of the reinforcing member 120. The interval between the adjacent fitting grooves 112 is the width between the end portions 121 of the reinforcing member 120.

  Further, a plurality of water passage holes 113 are formed so as to be adjacent to the fitting groove 112. This water passage hole 113 has a long slit shape and penetrates from the front surface to the back surface of the base plate 110, and can flow rainwater flowing from the surface of the base plate 110 to the back surface side. However, the size is such that the water-permeable pavement does not fall. In addition, if this water flow hole 113 is formed by the same formation method as the fitting groove | channel 112, after forming the fitting groove | channel 112, since the water passage hole 113 can be continuously formed as it is, work efficiency is good. In addition to the long slit shape, the short water passage holes 113 may be intermittently arranged on a straight line.

  Next, the reinforcing member 120 shown in FIG. The reinforcing member 120 is formed by cutting a metal flat thin plate so as to have a lateral width L3, and then bending the cross section so as to be uniform in a mountain shape over the entire length in the lateral width direction. And after arrange | positioning in the state which orient | assigned the longitudinal direction of this reinforcement member 120 to the horizontal width direction of the baseplate 110, after fitting the edge part 121 of the reinforcement member 120 in the fitting groove | channel 112 of the baseplate 110, it is the edge of the reinforcement member 120 The contact portion between the portion 121 and the base plate 110 is firmly attached by welding or the like.

  This fitting includes not only the case where the end 121 of the reinforcing member 120 is firmly fitted into the fitting groove 112 but also the case where the end 121 is fitted so weakly as to be engaged with the fitting groove 112. This is because the fitting groove 112 plays a role as a mark when the reinforcing member 120 is arranged on the base plate 110, and the role of this mark is sufficient to the extent that the end 121 is locked to the fitting groove 112. Because it fulfills. In addition, even when the end portion 121 is engaged with the fitting groove 112, the disposed reinforcing member 120 is not easily displaced, so that the mounting operation is facilitated. And if the contact location of the edge part 121 and the baseplate 110 is welded etc., the reinforcement member 120 will be firmly fixed to the baseplate 110. FIG.

  Further, the fitting groove 112 may or may not penetrate to the back surface of the base plate 110. When the fitting groove 112 does not penetrate to the back surface, the end portion 121 of the fitted reinforcing member 120 does not protrude from the back surface of the base plate 110. On the other hand, when the fitting groove 112 penetrates to the back surface, it is necessary to fit into the fitting groove 112 and fix by welding or the like so that the end portion 121 of the fitted reinforcing member 120 does not protrude greatly from the back surface of the base plate 110. There is. This is because it is difficult to stably place the side groove lid 100 on the flat placement surface 220 of the side groove 200 if the end 121 protrudes too much from the back surface of the base plate 110.

  Then, the reinforcing member 120 is fitted into and fixed to all the fitting grooves 112, thereby completing the side groove cover 100 shown in FIG.

  As shown in FIG. 1, the completed side groove lid 100 is placed on the placement surface 220 so as to cover the opening 210 of the side groove 200 embedded in the base layer R1. However, since the base plate 110 of the gutter lid 100 covers the opening 210, it is considered that the water-permeable pavement R2 can be prevented from flowing into the opening 210 only by the base plate 110. However, since the base plate 110 alone cannot withstand the weight of the water-permeable pavement R2 or the vehicle traveling on the surface of the water-permeable pavement R2, the strength is improved by the reinforcing member 120. Further, since the reinforcing member 120 is firmly installed on the mounting surfaces 220 on both sides via the base plate 110, it can sufficiently withstand this weight, and the function of the side groove cover 100 (water-permeable paved road R2). The function of draining rainwater or the like into the opening 210).

  Further, since the reinforcing member 120 located above the base plate 110 receives most of the weight of the water-permeable pavement R2 and the vehicle traveling on the surface of the water-permeable pavement R2 (hereinafter referred to as an external force), The reinforcing member 120 is preferably formed of a material having high rigidity. For example, high-strength steel or duralumin is optimal. Since these high-strength steels and duralumin can be reduced in thickness due to their high strength, they contribute to the weight reduction of the side groove lid 100.

  On the other hand, the external force applied to the base plate 110 is considerably reduced because the reinforcing member 120 receives most of it. Therefore, the rigidity of the material constituting the base plate 110 may be lower than that of the reinforcing member 120. Therefore, the reinforcing member 120 is formed of a material having high rigidity and the base plate 110 is formed of a material having rigidity lower than that of the reinforcing member 120. Then, since a material with high rigidity is generally expensive, the manufacturing cost of the entire side groove cover 100 can be reduced by limiting the portion where the expensive material is used to the reinforcing member 120.

  Further, when the reinforcing member 120 is placed directly on the placement surface 220 of the side groove 200, the external force is concentrated on the contact portion between the reinforcement member 120 and the placement surface 220. Therefore, as time passes, this external force gradually damages the contact portion with the reinforcing member 120, and unevenness occurs on the surface of the mounting surface 220. Then, the position and orientation of the reinforcing member 120 mounted on the surface of the mounting surface 220 gradually shifts, and between the water-permeable pavement R <b> 2 solidified by being poured around the reinforcing member 120 and the surface of the reinforcing member 120. There is a gap in Then, the gap causes a problem that the water-permeable pavement R2 is cracked or the water-permeable pavement R2 is damaged.

  However, in the present invention, as shown in FIG. 1C, the reinforcing member 120 is installed on the mounting surface 220 via the end 111 of the base plate 110, so that the external force received by the reinforcing member 120 is not applied. It does not act directly on the mounting surface 220. Therefore, damage on the surface of the mounting surface 220 can be reduced, and the above problem can be solved. Furthermore, the end 111 of the base plate 110 is a flat surface and is in surface contact with the mounting surface 220. Therefore, the flat end portion 111 disperses the external force from the reinforcing member 120, and a local load is prevented from being applied to the placement surface 220, thereby further reducing damage to the placement surface 220 surface.

  In the method of manufacturing the side groove lid 100 shown in FIG. 2, after the fitting groove 112 is formed, the end 121 of the reinforcing member 120 is fitted into the fitting groove 112 and fixed by welding or the like, and the reinforcing member 120 is attached. However, it is not limited to the said method. That is, even if the fitting groove 112 is not formed, the contact portion between the end 121 of the reinforcing member 120 and the base plate 110 is fixed by welding or the like with the reinforcing member 120 placed on the surface of the base plate 110. The reinforcing member 120 may be attached.

  Next, in the side groove lid 100D according to the modified example 4 shown in FIG. 3D, a plurality of reinforcing members 120D are attached and fixed on the base plate 110D at equal intervals. The reinforcing member 120D is formed by cutting a metal flat thin plate so as to have a lateral width L3, and then bending it so that the cross section is uniform in a U-shape over the entire length in the lateral width direction. . Then, in a state where the flat bottom surface 122D of the reinforcing member 120D is brought into contact with the surface of the base plate 110D, the contact portion is fixed by welding or the like. A water passage hole 113D is formed in the base plate 110D located between the reinforcing members 120D. However, the opening width of the upper end of the reinforcing member 120D is larger than that of the reinforcing member 120C shown in FIG.

  Next, in the side groove cover 100E according to the modified example 5 shown in FIG. 4A, a plurality of reinforcing members 120E are attached and fixed on the base plate 110E at equal intervals. The reinforcing member 120E is formed by cutting a metal flat thin plate so as to have a horizontal width L3, and then bending it so that the cross section is uniform in a U-shape over the entire length in the horizontal width direction. . The end 121E of the reinforcing member 120E is fitted into the fitting groove 112E of the base plate 110E and welded.

  Next, in the side groove cover 100F according to the modified example 6 shown in FIG. 4B, two reinforcing members 120F are attached and fixed on the base plate 110F. This reinforcing member 120F is formed by cutting a flat metal plate so as to have a lateral width L3, and then bending it so as to form a mountain shape having a gently inclined surface over the entire length in the lateral width direction. It is. The end portion 121F of the reinforcing member 120F is fitted into the fitting groove 112F of the base plate 110F and welded. A water passage hole 113F is formed in the base plate 110F located between the reinforcing members 120F. Since the reinforcing member 120F has a mountain shape with a gently sloping surface, the strength is improved by the rib 123F in order to prevent it from being crushed without being able to withstand external force from above.

  Next, in the side groove cover 100G according to the modified example 7 shown in FIG. 4C, a plurality of reinforcing members 120G are attached and fixed on the base plate 110G at equal intervals. The reinforcing member 120G is formed by cutting a flat metal plate so as to have a lateral width L3, and then uniforming the cross section in a bowl shape (a shape in which the lower end of the mountain shape is extended) over the entire length in the lateral width direction. In this way, it is bent. And the end part 121G of the reinforcing member 120G is fitted into the fitting groove 112G of the base plate 110G and welded. Further, a water passage hole 113G is formed in the base plate 110G located between the reinforcing members 120G.

  Next, in the side groove cover 100H according to the modified example 8 shown in FIG. 4 (d), the plurality of reinforcing members 120H are arranged at equal intervals and from the intervals between the reinforcing members 120 of the side groove cover 100A to the side groove cover 100G. The base plate 110H is attached and fixed at a wide interval.

And bent so as to be uniform. Rather than providing a water passage hole 124H in a ready-made product bent in advance in a chevron shape, a flat metal plate is cut to form the water passage hole 124H as described above, and then bent at the center. It is easier to manufacture in the shape of a chevron.

  The end portion 121H of the reinforcing member 120H is fitted into the fitting groove 112H of the base plate 110H and welded. Further, a water passage hole 113HA is formed in the base plate 110H located between the reinforcing members 120H, and a water passage hole 113HB is formed in the base plate 110H located inside and below the reinforcing member 120H. The water passage hole 113HB is for flowing rainwater collected from the water passage hole 124H of the reinforcing member 120H to the side groove below the side groove cover 100H.

In the present invention, the reinforcing member has a length that can be placed on the placement surfaces on both sides of the side groove via the base plate. Any shape can be used as long as the shape is “na”. Therefore, as shown in the side groove cover 100A according to the modification 1 to the side groove cover 100H according to the modification 8, the reinforcing members having various shapes (the reinforcing member 120A to the reinforcing member 120H) are used depending on the situation of use. Can be adopted. Of course, the height of the reinforcing member can also be arbitrarily changed according to the depth to be embedded.

  In particular, the thickness of the water-paved pavement constructed on the gutter lid needs to satisfy the specified value defined by safety standards, etc., depending on the environment of the road where the gutter is installed. In addition, if the height of the existing reinforcing member (angle type steel) is large, the thickness of the water-permeable pavement will be reduced by that amount, and the specified value may not be satisfied (or the specified value is satisfied). Therefore, the thickness of the water-permeable pavement must be increased). However, in the present invention, since the shape of the reinforcing member can be arbitrarily formed, for example, if the height of the reinforcing member is lowered, the thickness of the water-permeable pavement can be increased accordingly, and the water-permeable pavement can be increased. It becomes easier to meet the specified value of the road. Furthermore, if the reinforcing member is made of a material having high rigidity, the height and thickness of the reinforcing member can be reduced, and the thickness of the water-permeable pavement can be increased accordingly. It becomes easier to satisfy the value.

  In addition, depending on the road environment (gradient etc.) where the gutter is installed, it is necessary to adjust the thickness of the water-permeable pavement constructed on the gutter lid to the desired thickness. In the existing reinforcing member (angle type steel), the height is limited to a predetermined standard value, so that it is difficult to adjust the thickness of the water-permeable pavement constructed on the side groove cover. However, in the present invention, since the shape of the reinforcing member can be arbitrarily formed, for example, the height of the reinforcing member can be arbitrarily adjusted so that the thickness of the water-permeable pavement becomes a desired thickness.

  Further, it is necessary to determine how the reinforcing members should be arranged and attached. However, in the present invention, as long as the reinforcing members are "attached horizontally on the base plate", the reinforcing members of each other There is no need to consider the positional relationship (especially the interval). Therefore, as shown in FIG. 4 (d), the reinforcing members 120H can be arranged to be separated from each other at an arbitrary interval.

  That is, in the technique of the conventional patent document 1, the interval S must be secured so that the water-permeable pavement material does not fall from between the respective mountain-shaped members 30 (reinforcing members). There was a restriction on the interval. Therefore, the freedom degree of design, such as a shape and arrangement | positioning of a reinforcement member, was restrict | limited.

  However, in the present invention, the water-based pavement material can be obtained by utilizing a “base plate that covers the opening of the side groove and can be placed on the placement surfaces on both sides of the side groove, and has water passage holes”. There is no need to consider the problem of depression, and the shape and spacing of the mutual reinforcing members are released.

  Furthermore, even the condition that “a reinforcing member is formed on the mounting surface on both sides so that it can be placed via the base plate, and the reinforcing member is mounted on the base plate in the lateral width direction” can be observed. For example, the function of the side gutter lid (the ability to withstand the weight of water-permeable paved roads and vehicles, and the function of draining rainwater etc. into the side gutter) can be fully exhibited, and the shape and spacing of the reinforcing member can be reduced under these conditions. Since it can be determined freely, the design freedom of the side groove cover 100 is very high. Moreover, since the space | interval of reinforcement members can be enlarged, the number of reinforcement members can be reduced rather than the conventional patent document 1, As a result, the manufacturing cost of the side groove cover 100 can also be suppressed.

  In addition, in the side groove cover 100A according to Modification Example 1 to the side groove cover 100H according to Modification Example 8, the cross-sectional shapes of the reinforcing members are all uniform across the width direction. However, the present invention is not limited to this, and a reinforcing member having a shape whose cross-sectional shape changes in the lateral width direction (for example, a reinforcing member having a wavy surface) may be used.

(Modification 9)
Furthermore, below, the side groove cover 100I which is the modification 9 of the side groove cover 100 of this invention is demonstrated with reference to FIG. The side groove lid 100I is different from the side groove lid 100 in that the shape of the reinforcing member 120I, the twist bar (connecting rod) TB, and the side plate SB are used. Since it is the same structure, detailed description is omitted.

  First, as shown in FIG. 5A, the base plate 110I of the side groove cover 100I according to the modification 9 has a plurality of water passage holes 113I formed at arbitrary intervals. Next, the long I-shaped reinforcing member 120I shown in FIG. 5B is erected and fixed on the base plate 110I. However, the reinforcing member 120I cannot withstand external force and may fall down. is there. Therefore, as shown in FIG. 5 (b), through holes are provided in the front and rear surfaces of each reinforcing member 120I, and the twist bar TB is passed through the through holes in a skewered manner. And the contact location of each reinforcement member 120I and twist bar TB is firmly fixed by welding etc., and it prevents that the reinforcement member 120I falls down. Furthermore, the long side plate SB is contacted and welded to both end faces of the reinforcing member 120I to prevent the reinforcing member 120I from falling down more reliably. In addition, the position which penetrates twist bar TB can be changed into the arbitrary positions of the lower end from the upper end in the front-back surface of the reinforcing member 120I according to the objective. Similarly, the position where the side plate SB is attached can be changed from the upper end to the lower end of the reinforcing member 120I according to the purpose.

  Then, the reinforcing member 120I connected in a lattice shape by the twist bar TB and the side plate SB is arranged on the base plate 110I, and the contact point between the two is fixed by welding or the like. Then, the side groove cover 100I shown in FIG. 5C is completed.

(Modifications 10 and 11)
Next, the side groove cover 100J and the side groove cover 100K which are the modifications 10 and 11 of the side groove cover 100I will be described with reference to FIG. In the side groove lid 100J and the side groove lid 100K, the configurations of the base plate 110J and the base plate 110K are different from those of the side groove lid 100I, but the other configurations are the same as those of the side groove lid 100I, and detailed description thereof will be omitted.

  As shown in FIG. 6A, the side groove cover 100J is configured in a state in which a base plate 110Ja, a base plate 110Jb, and a base plate 110Jc having a lateral width L1 are juxtaposed. And it arrange | positions with the space | interval of the grade which a water-permeable pavement material does not fall mutually, and this clearance gap becomes the water flow hole 113J. When the reinforcing member 120J connected in a lattice pattern by the twist bar TB and the side plate SB is arranged on the base plate 110J and the contact portions of both are fixed by welding or the like, the side groove cover 100J is completed.

  Next, as shown in FIG. 6B, the side groove cover 100K is in a state where the three base plates 110Ka, the base plate 110Kb, and the base plate 110Kc are arranged in parallel, and from the outer end of the base plate 110Ka. The width to the outer end of the base plate 110Kc is configured to be the lateral width L1. And it arrange | positions with the space | interval of the extent which a water-permeable pavement material does not fall mutually, and this space | gap becomes the water flow hole 113K. When the reinforcing member 120K connected in a lattice shape by the twist bar TB and the side plate SB is arranged on the base plate 110K and the contact portions of both are fixed by welding or the like, the side groove cover 100K is completed.

(Modification 12)
Next, a side groove cover 100L, which is a modification 12 of the side groove cover 100K, will be described with reference to FIG. In the side groove lid 100L, the insertion plate X is used instead of the twist bar TB and the side plate SB, but the other configuration is the same as that of the side groove lid 100K, and detailed description thereof is omitted.

  As shown in FIG. 6C, the insertion plate X is formed with a plurality of notches XC into which the reinforcing member 120L can be fitted. And it can prevent that each reinforcement member 120L falls down by inserting the notch XC of the insertion plate X into the upper end of each reinforcement member 120L, and fixing the inserted position by welding.

(Modifications 13 and 14)
Next, the side groove cover 100M and the side groove cover 100N for placement in the curved side groove used in the corner portion of the road shoulder and the like will be described with reference to FIG.

  As shown in FIG. 7A, the base plate 110M of the side groove cover 100M according to the modified example 13 is cut into a large shape and is in a strip shape. Specifically, a flat metal plate is cut so as to have a lateral width L1, and wide water passage holes 113M are formed at equal intervals. And let the remaining part be the installation surface 114M which installs the reinforcement member 120M.

  Next, a metal flat thin plate is cut to have a lateral width L3, a water passage hole 124M is formed at the center thereof, and then bent into a mountain shape at the center to form a reinforcing member 120M. Then, only one end 121Ma of the reinforcing member 120M is fixed to the installation surface 114M by welding or the like, and the other end 121Mb is simply installed on the installation surface 114M without performing welding or the like. By performing this on all the installation surfaces 114M, the side groove cover 100M is completed (in FIG. 7A, in order to make the structure of the side groove cover 100M easy to understand, the reinforcing member 120M is attached halfway. However, when actually used, the reinforcing members 120M are attached to all the installation surfaces 114M).

  When the side groove cover 100M is actually put on the curved side groove, the side groove cover 100M is bent according to the curve of the side groove. That is, the entire base plate 110M is curved inward so that the tips of the installation surface 114M (on the side opposite to the end portion 111Ma) are close to each other (in the plan view, the side groove lid 100M is deformed into a gentle bow shape). To bend). Then, after covering the side groove lid 100M with the curved side groove, the water-permeable pavement material is poured from above to complete the pavement (see FIG. 1 (c)). In addition, the rainwater which permeate | transmitted the water-permeable pavement is discharged | emitted by the lower side ditch from the water passage hole 124M through the water passage hole 113M.

  Here, only one end 121Ma of the reinforcing member 120M is fixed to the installation surface 114M by welding or the like, and the other end 121Mb is simply placed on the installation surface 114M without welding or the like. Without any problem, the base plate 110M can be curved by bringing the tips of the installation surface 114M (the side opposite to the end portion 111Ma) close to each other.

  Next, as shown in FIG. 7B, the base plate 110N of the side groove cover 100N according to the modified example 14 is formed into a strip shape with a large cut. Specifically, a metal flat thin plate is cut so as to have a lateral width L1, and the water passage hole 113NA that gradually increases in width is formed. And let the remaining part be the installation surface 114N which mounts and fixes the reinforcement member 120N. Further, a water passage hole 113NB is also formed on the installation surface 114N.

  Next, a metal flat thin plate is cut to have a lateral width L3, a water passage hole 124N is formed at the center thereof, and then bent into a mountain shape at the center to form a reinforcing member 120N. Then, both end portions 121N of the reinforcing member 120N are fixed to the installation surface 114N by welding or the like. By performing this operation on all the installation surfaces 114N, the side groove cover 100N is completed. (In FIGS. 7B to 7D, the side groove cover 100N is reinforced halfway for easy understanding. The member 120N is attached, but when actually used, the reinforcing member 120N is attached to all the installation surfaces 114N.)

  When the side groove cover 100N is actually put on the curved side groove, the side groove cover 100N is bent according to the curve of the side groove. That is, as shown in FIG. 7D, the entire base plate 110N is curved inward so that the tips of the installation surface 114N (on the side opposite to the end portion 111Na) are close to each other. Then, the water passage hole 113NA (see FIG. 7 (c)) formed so as to gradually become wider is narrowed so that the width becomes uniform as shown in FIG. 7 (d), and The width is such that the water-permeable pavement does not fall downward.

  Then, after covering the side groove lid 100N with the curved side groove, the water-permeable pavement material is poured from above to complete the pavement (see FIG. 1 (c)). In addition, the rainwater which permeate | transmitted the water-permeable pavement is drained to a lower side ditch from the water passage hole 124N through the water passage hole 113NB. In addition, rainwater guided by the slope of the reinforcing member 120N is drained into the lower side groove through the water passage hole 113NA.

  Here, FIG. 8 shows another example of how the side groove cover 100 of the present invention shown in FIG. 1 is used. 8 is different from the side groove 200 shown in FIG. 1 except that the upper end wall 230 of the side groove 200 is cut away, and the other points are the same as those of the side groove 200 shown in FIG. .

  In FIG. 8A, the upper half of the upper end wall 230 of the side groove 200 is cut away, and the upper end after the cut is substantially flush with the upper surface of the side groove lid 100. In this state, a water-permeable pavement material is poured to form a water-permeable pavement path R2. In addition, even if it does not cut out, you may use the side groove | channel 200 from which the height of the upper end wall 230 becomes substantially the same plane as the upper surface of the side groove cover 100 from the beginning.

  Next, in FIG.8 (b), all the upper end walls 230 of the both sides of the side groove | channel 200 are excised, and the upper end of the side groove | channel 200 is substantially the same plane as base layer R1. And in that state, a water-permeable pavement material is poured to form a water-permeable pavement R2. Further, in FIG. 8C, the upper end wall 230 on one side of the side groove 200 is all cut away, and the upper end of the cut side groove 200 is substantially flush with the base layer R1. And in that state, a water-permeable pavement material is poured to form a water-permeable pavement R2.

  In addition, the manufacturing method of the side groove cover of this invention and a side groove cover are not limited to said Example, A various modification and combination are possible in the range described in the claim and the range of embodiment. These modifications and combinations are also included in the scope of the right.
