Description

  The present invention relates to a road structure on which paving such as asphalt pavement, tile pavement, and water-permeable pavement provided with side grooves and a side groove block used in the structure.

  A side groove for draining rainwater and snowmelt water is provided along the side of the road. This gutter may be provided at the boundary between the sidewalk and the roadway, or may be provided on the sidewalk or on both the sidewalk and the roadway.

  A U-shaped groove is widely used as a side groove provided on the road, and a cover plate for closing the upper surface opening is generally provided. That is, a U-shaped groove is embedded along the side (road side) of the road, and the upper surface of the road is paved with a thickness that is flush with the upper surface of the U-shaped groove (the side wall top surface of the side groove body). The top surface of the lid plate dropped in and the surface of the paved road are made to have the same height. In addition, the water on the road flows into the U-shaped groove through notches provided in the lid plate and lattices of grating lids (lattice lids) provided in places.

  In the sidewalk having the above structure, a road surface is formed by a continuous cover plate on the side of the paved sidewalk surface. This road surface is difficult to walk due to notches and gratings, steps between adjacent lid surfaces, and rattling when passing. In addition, the cover plate may rattle and generate noise, and if the sidewalk surface is asphalt pavement, it may be worn away for many years and a step may be formed between the side grooves.

  If the sidewalk is wide enough, you only need to pass through the paved surface, but if the sidewalk is narrow, you will have to pass on the cover plate when you walk side by side or pass a bicycle. At this time, it is not only difficult to walk by stepping on steps, bicycle wheels getting caught, making noise when walking, and stepping into the notch, there is also a risk of falling is there. Furthermore, the road surface with continuous cover plates impairs the aesthetics of the road, and narrow sidewalks appear to be narrower, especially when the road surface becomes old, giving a cluttered impression.

Along the upper surface of the pavement layer 20 is formed with an inner ridge 19 that is not the same height as the upper surface of the pavement layer 20, and a drain fitting 18 and a drain port 33 are provided between the top of the side wall and the inner ridge. By adopting a structure that allows rainwater or the like to flow into the side grooves, the above-mentioned problems are solved.

  Further, in the invention of claim 4 of the present application, the upper surface of the side groove 5 embedded along the side of the road 2 and the upper surface of the road base 4 are covered with a pavement layer 20 such as asphalt pavement, tile pavement, water permeable pavement and the like. On the lid plate 7 of the side groove, a side wall 40 is formed along the edge on the side opposite to the road, and the inner wall is not flush with or slightly lower than the upper surface of the pavement layer 20 inside the side wall. 19 is formed, and the drain metal fitting 18 and the drain port 33 are provided between the side wall and the inner wall, and the above-described problem is solved by adopting a structure in which rain water or the like on the pavement layer 20 flows into the side groove. It is a thing.

  The side groove may be any structure of a U-shaped groove, a variable gradient side groove, and a side-cast concrete side groove. Especially, when renovating an existing sidewalk having this type of side groove, The appearance and function can be greatly improved.

  In particular, if the existing side groove is a U-shaped groove of a concrete block or a cast-in-place concrete, it is easy to modify the existing road to have the structure of the present invention. The structure of the paved road according to the invention of claim 5 of the present application is characterized in that the side groove is a U-shaped groove in the structure of the paved road provided with the above-mentioned means.

  When the pavement layer 20 is made of water permeable pavement, a water permeable port 44 through which rain water or the like flowing in the pavement layer 20 flows into the side groove is provided along the edge of the pavement layer 20. Such a water permeable port 44 is provided on the upper surface or edge of the lid plate 7 in the side groove or on the side surface of the drain fitting 18.

  The invention according to claims 6 to 8 of the present application is a side groove cover plate block suitable for use in the above-described side groove structure of the present invention.

  That is, the lid plate block according to the invention of claim 6 of the present application is a lid plate block suitable for use in the lateral groove structure according to the invention of claim 2, and is arranged on the inner side of the U-groove lid hook 22 on one side. And a notch 21 that extends from the upper surface to the lower surface so as to open inward and penetrates, and an insert nut 23 for a bolt that fixes the drain fitting 18 or the drain port forming fittings 32 and 38. It is a cover plate block for side grooves.

  The side groove cover plate block according to the seventh aspect of the present invention is a cover plate block suitable for use in the side groove structure according to the third aspect of the present invention, and is arranged on one side of the inside of the U-shaped groove cover 22. A notch 21 that extends inward from the upper surface to the lower surface so as to be opened inward, and an inner flange 19 that protrudes from the upper surface at a height substantially equal to the thickness of the pavement layer 20 on the road surface. It is a lid plate block for side grooves provided with the protrusion part 41 which protrudes from the outer surface of the said inner collar at the height which is the same as this or lower than this.

  Further, the side groove cover plate block according to the invention of claim 8 of the present application is a cover plate block suitable for use in the side groove structure according to the invention of claim 4, and a side rod 40 protruding from the upper surface of one side, An inner flange 19 projecting at a height substantially equal to the thickness of the pavement layer 20 on the road surface with a gap between the side fence and a notch 21 or a through hole communicating between the side fence and the inner fence to the lower surface. 35 is a gutter cover plate block.

This is a variable gradient block including a side rod 40 and a through hole 35 that is in close proximity to the inside of the side rod and communicates with the flow path 8 of the block.

  According to the present invention, a wide road surface without steps and rattling paved with the same pavement material is obtained, and the road width is not narrowed by the side groove, so a side groove having a sufficient flow path area is provided. This is easily possible, and the water inlet to the gutter is also provided at the edge of the road, so there is no obstacle to traffic. Also, since the entire road surface including the upper part of the gutter can be paved with the same pavement material, there will be no steps on the road surface due to wear, and the lid plate will rattle or generate noise. Nor. Therefore, according to the present invention, it is possible to obtain a wide road surface that is easy to pass and excellent in appearance without widening the road width.

  Further, in the pavement structure of the present invention, the water flow openings such as the drain hole 14 and the drain port 33 of the drain fitting that allow rainwater on the road to flow into the side grooves are opened on the upper surface of the pavement layer 20. Regardless of whether or not 20 has water permeability, rain water or the like on the road can flow into the side groove. Since the water conduits 21 and 35 formed by the drain fitting 18 and the drain port 33 have a small flow resistance, the flow area is small, and a large-area flow path and a large number of flow paths are provided on the lid plate 7 of the side groove. It is possible to avoid a reduction in the strength of the cover plate due to the formation.

  Furthermore, according to the invention of claim 5 of the present application, there is an effect that it is possible to easily modify a road having a U-shaped groove to provide a road having the structure of the present invention.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a road showing a first embodiment of the present invention in a sidewalk provided with a U-shaped groove, wherein 1 is a roadway, 2 is a sidewalk, and 3 is a private land adjacent to the sidewalk. A boundary block 11 is provided between the sidewalk 2 and the roadway 1, and a box 12 for draining water from the roadway 1 is provided below the boundary block 11. A U-shaped groove 5 a is provided along the edge of the sidewalk 2 on the side of the private land 3, and the upper surface opening of the main body of the U-shaped groove is closed by a cover plate 7.

  Details of the side of the sidewalk 2 are shown in FIG. The height of the side wall 15 on the private land 3 side of the U-shaped groove 5a is higher than the height of the side wall 16 on the road side by the layer thickness t of the pavement layer 20 on the road surface. The lid plate 7 is fitted with its upper surface being flush with the top surface of the side wall 16 on the road side. Accordingly, a step 17 corresponding to the pavement thickness t on the road surface is formed between the upper surface of the cover plate 7 and the top 25 of the U-shaped groove-side wall 15.

  A stainless steel drain fitting 18 is arranged along the inside of the step 17, and the upper surface of the road-side cover plate 7, the top surface of the road side wall 16 of the side groove, and the upper surface of the sidewalk base 4 from the drain fitting. A pavement layer 20 on the surface of the sidewalk such as asphalt pavement or tile pavement is formed.

  As shown in FIG. 3, the cover plate 7 is provided with a notch 21 on the side of the private land 3 that communicates from the upper surface to the lower surface. This notch 21 has a shape that is expanded inward from the upper surface to the lower surface side, and is opened inside the U-groove cover hook 22. Insert nuts 23 for bolts for fixing the drain fitting 18 or a molded fitting 32 described later are embedded on both sides of the upper surface opening of the notch 21. An insert nut 24 for attaching a suspension bolt is embedded in the center of the upper surface of the lid plate 7.

  Next, with reference to FIG. 4, the construction procedure which makes the sidewalk provided with the existing U-shaped groove the structure of this invention shown in FIG. 1 is demonstrated. First, the conventional lid plate covered with the existing U-shaped groove is removed, and the pavement material on the surface of the old sidewalk is deleted with a desired thickness. Further, the top of the side wall on the road side of the U-shaped groove is cut by a height corresponding to the thickness of the pavement layer 20 on the sidewalk surface. This height is usually 2 to 3 cm (FIG. 4 (a)).

  Next, the lid plate 7 formed with a thin thickness corresponding to the lower side wall 16 of the U-shaped groove 5a is fitted into the U-shaped groove 5a. As shown in FIG. 3, the lid plate 7 is a lid plate provided with a notch 21 on one side, and covers the lid plate 7 in such a direction that the notch 21 faces the private land 3 side. When a rattle or a gap is generated between the lid plate 7 and the lid hook 22 of the U-shaped groove 5a, a cushioning material is applied to the step and the lid plate 7 is fitted.

  Since a step is formed between the upper surface of the fitted lid plate 7 and the top portion 25 of the U-shaped groove on the private side wall, the drain fitting 18 is fixed with a countersunk bolt 26 along this step (FIG. 4). (C), see FIG. Then, on the road side of the drain metal fitting 18, a pavement layer 20 that covers the cover plate 7, the U-groove road side wall 16 and the upper surface of the road base 4 is constructed.

  Even if there are steps or irregularities on the top surface of the cover plate 7, the side walls 16, and the road base 4, the surface of the sidewalk can be made a road surface without steps or irregularities by the pavement layer 20 that integrally covers these. Rainwater on the sidewalk 2 flows down into the flow path of the U-shaped groove 5a through the drain fitting 18 and the notch 21 of the cover plate.

  When the pavement layer 20 is a water permeable pavement layer, as the drain fitting 18, one having a water permeable hole 34 on the side surface as shown in FIG. 6 is used. Even in the case of permeable pavement, the drain hole 14 on the upper surface of the drain fitting 18 is necessary in order to quickly drain the rain water overflowing on the pavement layer. The drain metal fitting 18 can have an appropriate shape such as a rectangular cross section, for example, but the inverted trapezoidal cross section shape shown in FIG. 6 can be removed relatively easily even after the pavement layer 20 is provided. Therefore, the replacement work of the metal fitting is easy. Moreover, the drain metal fitting 18 is good also as a structure provided intermittently in the location which provided the notch 21 with the short thing.

  If the pavement layer 20 is constructed with the pavement material of the pavement layer 20 protruding (covered) on the upper surface of the drain metal fitting 18, it becomes difficult to replace the drain metal fitting 18. In such a case, as shown in FIG. 7, as shown in FIG. 7, a pavement stopper 36 having an L-shaped cross section is attached to the inner side (road side) of the drain bracket 18 by screwing it to an insert nut provided on the lid plate 7. Then, the pavement layer 20 is formed inside the pavement stopper. When the pavement layer 20 is a water-permeable pavement, the drain metal fitting 18 having the water-permeable holes 34 shown in FIG. 6 is used, and the vertical wall portion of the pavement stopper 36 has water-permeable holes. Is used.

  It is also possible to provide a drain port communicating with the notch 21 of the cover plate at the side edge of the pavement layer 20 in place of the drain fitting 18 to guide rainwater or the like into the U-shaped groove 5a. 8 and 9 are diagrams showing the structure and construction procedure in that case. As shown in FIG. 8, a notch 21 is formed in a band-shaped metal plate which is bent in an L shape to form a seat plate 30 at a portion where the notch 21 is opened on the upper surface of the lid plate, and is trapezoidal in plan view. The drain-opening metal fitting 32 that is bent is fixed with a screw 26 using the insert nut 23 (FIG. 9C).

  Then, the pavement layer 20 is applied to the upper surface of the lid plate 7, the road side wall 16 and the road base 4 so that the pavement material does not enter the inside of the molded metal fitting 32, thereby along the side edge of the pavement layer 20. A drain port 33 that communicates intermittently with the U-shaped groove 5a is formed (FIG. 9D).

  In the example of FIG. 8, the short drain port 33 is intermittently provided between the top 25 of the side wall opposite to the side wall of the gutter body and the edge of the pavement layer 20. FIGS. 10 and 11 show an example in which is provided in a narrow band shape. That is, by using the same shape as the pavement stopper 36 of FIG. 7 as the forming metal fitting 38 for forming the drain port 33, the pavement layer 20 is constructed on the inner side of the forming metal fitting 38, thereby forming the pavement layer. A continuous slit-shaped drain port 33 is formed between the edge 20 and the top 25 of the side wall of the side groove opposite the road. When the pavement layer 20 is a water permeable pavement layer, as shown in FIG. 11, a metal fitting 38 having a water permeable hole 34 in a vertical wall portion is used. Rainwater or the like that has passed through the drain port 33 or the water permeable hole 34 flows into the side groove 5 through the notch 21 of the cover plate as illustrated in FIG.

  In place of the drain port metal fitting 38 of FIG. 10, an inner collar 19 having a function as a molding wall may be integrally provided on the side of the lid plate 7. FIGS. 12 to 17 are views showing an example of this. FIG. 12 shows a slit-like shape between the top 25 of the side wall of the side groove on the side opposite to the road and the inner flange 19 provided on the side edge of the lid plate 7 on the side opposite to the road. It is the figure which showed the example which provided the drain port 33 opened to.

  As shown in FIGS. 13 to 15, the lid plate 7 used in the structure of FIG. 12 is formed by integrally forming a drainage cutout 21 and an inner flange 19 on the opposite side edge of the road. The inner collar 19 is provided at a position retracted inward by the width of the drain port 33 (about 10 mm) from the side surface of the lid plate on the side opposite to the road. It protrudes from the outer wall surface of the inner collar 19.

  As shown in FIG. 14, if the protrusion 41 is provided up to the height of the top of the inner flange 19, the drain port 33 opens intermittently between the side wall top 25 of the side groove body and the inner flange 19. Further, as shown in FIG. 15, the protruding amount of the protruding portion 41 is the width dimension of the drain fitting 18, and the height of the top portion is made lower than the upper surface of the inner collar 19 by the height of the drain fitting 18. If an insert nut for screwing the fixing screw of the drain metal fitting is provided at the top, the drain metal fitting 18 can be provided between the side wall top of the side groove main body and the inner flange 19 of the lid plate.

  When the pavement layer 20 is a permeable pavement layer, as shown in FIG. 16, a water permeable port 44 for guiding the water flowing in the pavement layer 20 into the side groove is formed at the inner root portion of the inner collar 19. deep. The water permeation port 44 is provided with a filter or eye plate 45 as necessary. In addition, by providing a gradient in the direction in which the inner flange 19 side is lowered on the upper surface of the lid plate 7, rainwater flowing in the permeable pavement layer 20 can be smoothly guided to the permeable port 44.

  In addition, when performing so-called raised pavement in which the upper surface of the newly constructed pavement layer 20 is higher than the existing sidewalk surface, the height of the upper surface of the inner flange 19 is higher than the height of the side wall top 25 of the side groove main body. As shown in FIG. 17, it is preferable to use a structure in which rain water or the like on the pavement layer 20 flows down to the drain fitting or the drain port 33 along the slope with the outer surface of the inner ridge 19 as the slope.

  In addition, the construction procedure shown in FIG.4 and FIG.9 has shown the process of repairing the existing sidewalk provided with the U-shaped groove. When a sidewalk is newly built including a U-shaped groove, if the U-shaped groove 5a in which one side 16 of the side wall is lower than the other 15 by an amount corresponding to the thickness of the pavement layer 20 is used and used, The work of excising the top becomes unnecessary.

  Further, when a U-shaped groove block is newly formed, as shown in FIG. 18, a through hole 35 is provided in the lid plate 7 instead of the notch 21, and the through hole is formed in the portion of the lid hook 22 of the U-shaped groove block. It is also possible to form a notch groove 37 that communicates with the outlet of 35 so that the upper surface of the lid plate 7 communicates with the U-shaped groove. The through-hole 35 provided at this time is provided in a size and a position that opens inside the drain fitting 18 and the drain port forming fitting 32.

  The above example relates to a side groove having a structure in which the lid plate 7 is dropped and the lid is attached in a state where the lid plate 7 is dropped between the side wall tops of the side groove body. In the case where the plate is placed on the top of the side wall on both sides of the gutter body, or when the amount of the newly built pavement layer is large, the space between the side rod 40 and the inner rod 19 provided on the side of the lid plate A structure in which a drain metal fitting or a drain port is provided in is suitable.

  FIG. 19 is a diagram showing an example of this, and is an example in which the drain fitting 18 is provided between the side rod 40 and the inner rod 19 formed along the opposite side edge of the lid plate 7. As shown in FIG. 3, a groove 42 for fitting the drain metal fitting 18 is provided between the side rod 40 and the inner rod 19, and the groove 42 is formed on the opposite side of the side of the lid plate from this groove. The cutout 21 or the through hole 35 communicating with the lower surface of the lid plate is formed, and an insert nut is appropriately provided on the bottom surface of the groove so that the drain fitting 18 is screwed. When the pavement layer is a water-permeable pavement, the water-permeable port 44 as described with reference to FIG.

  The inner collar 19 has a function of forming an edge of the pavement layer 20, and the height of the collar is preferably the same as or slightly lower than the upper surface of the pavement layer 20. On the other hand, the height of the side fence 40 is preferably higher than the upper surface of the pavement layer when it is desired to prevent rainwater or the like on the sidewalk from flowing into the private land.

  When newly installing a side groove, in addition to using the U-shaped groove as described above, a variable gradient block 5b shown in FIGS. 20A and 20B can be used. 20A is an example of a drop lid structure, FIG. 20B is an example of a cover lid structure, 39 is an upper surface of a gutter body, 40 is a side fence provided on the side edge of the side opposite to the road, and 35 is a side fence 40. A through-hole 43 provided close to the inside of the main body 43 is an opening provided on the upper surface of the main body. The height of the side wall 40 is set to a height corresponding to the thickness of the pavement layer 20, and the through hole 35 is provided adjacent to the inside of the side wall so as to communicate with the channel 8 of the side groove.

  Such a side flange 40 and a through hole 35 are provided in the main body of the gradient variable side groove 5b, and a cover plate having a normal structure is covered, and a drain fitting 18 is attached inside the side flange 40 or around the through hole 35. Drain port forming metal fittings 32 and 38 are provided on the inner side, or the inner collar 19 is integrally formed on the main body upper surface 39 with the through hole 35 interposed therebetween, and the lid plate covered with the opening 43, the upper surface of the main body, and the road base By providing a pavement layer that integrally covers, a road structure similar to that described for the U-shaped groove can be obtained.

  In addition, in the case of the gradient variable side groove of the drop lid structure shown in FIG. 20A, the cover plate having the structure shown in FIGS. 5 and 8 is provided in the opening 43, and the cover lid structure of FIG. In this case, by providing a cover plate having the side rod 40 shown in FIG. 22 and the through hole 35 inside thereof, the cover plate portion can also have a drainage function such as rain water on the upper surface of the pavement layer. .

  FIG. 21 is a cross-sectional view showing a structure when a drain plate 33 is formed by the drain port forming metal fitting 32 by providing a cover plate having a through hole 35 in the gradient variable side groove of FIG.
