Description

  The present invention relates to a road side groove such as a U-shaped side groove, a side groove unit such as a U-shaped side groove on which a concrete lid and a grating lid placed on the road side groove, and a grating lid used for the same. The present invention relates to a gutter unit capable of improving the drainage capacity of a concrete gutter installed on a road on which asphalt is laid and a grating lid used therefor.

2. Description of the Related Art Conventionally, as a road side groove provided with a grating lid, one having a configuration as shown in FIGS. 18 to 20 is known. Here, FIG. 18 is an overall configuration of a side groove unit provided with a grating lid, FIG. 19 is an overall configuration diagram of a road side groove, and FIG. 20 is a perspective view showing an overall configuration of the grating lid. FIG. 21 is an explanatory view showing a state in which a gap is formed in the grating lid or the concrete lid in the conventional gutter unit, and a positional deviation occurs. FIG. 22 shows a state in which rainwater flows from the road with respect to the conventional gutter unit. It is a cross-sectional perspective view. In the figure, the symmetrical parts are indicated by the same reference numerals, and the same components or equivalent parts are indicated by the same reference numerals, and redundant description thereof is omitted.
As shown in the drawing, the side groove unit 1 is configured such that, for example, one or more concrete lids 20 and one or more grating lids 30 are placed on a concrete side groove 10 serving as a base. In the installation of the gutter unit 1 on the road, first, a concrete groove which is slightly larger and deeper than the outer shape of the concrete gutter 10 is dug along the road and the foundation concrete is struck. Sets the direction of water flow on the inner bottom surface 11 and is placed so that the end surfaces of both rising portions 12 are in contact with each other, and the contact surfaces are hardened with mortar or the like to connect the concrete side grooves 10.

Here, on the upper part on the inner wall side of both rising portions 12 of the concrete side groove 10, a leg receiving surface 14 having a step difference lower than the upper surfaces of both rising portions 12 is formed. As shown in FIG. 18, a concrete lid 20 and a grating lid 30 formed with substantially the same width are placed on the leg receiving surfaces 14 of both rising portions 12 of the concrete side groove 10.
In this state, the upper surfaces 13 of the two rising portions 12 of the concrete side groove 10 are substantially flush with the upper surface of the concrete lid 20 and the upper surface of the grating lid 30. Then, asphalt is laid on the road so as to be substantially flush with the upper surface 13 of both rising portions 12 of the concrete side groove 10. In other words, the road surface is usually slightly inclined, but the upper surfaces 13 of the two rising portions 12 of the concrete side groove 10, the concrete lid 20 and the grating lid 30 are substantially the same as the road surface. To be institutionalized.

  By the way, the above-mentioned side groove unit 1 has a configuration in which a grating lid 30 having the same width as the concrete lid 20 is simply arranged with respect to the concrete side groove 10. The portion is cut off to form a gap, cracks and falls into the side groove, or part of the vehicle jumps up when the vehicle or the like is stepped on. Also, as shown in FIG. There is a problem that a gap is formed between the grating lid 30 and the grating lid 30, a positional shift occurs, and the connecting portion between the road side groove and the leg receiving surface 14 rises to a seesaw state and noise is generated. Further, when a large force from above is applied to the grating lid 30, it is intensively applied only to the leg receiving surface 14 via the leg member 35, and the leg receiving surface 14 or the concrete side groove 10 of both rising portions 12 of the concrete side groove 10 is formed. It can also be damaged.

Furthermore, in recent years, water-permeable asphalt is often laid on road foundation concrete. This has advantages such as good drainage of the road when it rains, no rainwater collecting on the permeable asphalt surface, and improved forward visibility of the vehicle driver at night.
However, when the gutter unit 1 as described above is installed on the road, even if a permeable asphalt 50 is laid on the road, as shown in FIG. Once rainwater permeates into the water-permeable asphalt 50, it remains in the water-permeable asphalt 50 and cannot flow into the concrete side groove 10 in this state. That is, the rainwater that has penetrated into the water permeable asphalt 50 eventually reaches the surface of the water permeable asphalt 50 and then flows over the upper surface 13 of the rising portion 12 of the concrete side groove 10 and flows into the concrete side groove 10. For this reason, even if the water-permeable asphalt 50 is laid on the road, when the amount of rainfall exceeds a predetermined amount, water floats on the surface of the water-permeable asphalt 50 and the effect is halved.

  Accordingly, the present invention has been made to solve such problems, and can efficiently guide rainwater or the like that has permeated into a road laid with water-permeable asphalt to a concrete gutter, and is disposed in a concrete gutter. Providing a side groove unit that can prevent the displacement of the grating lid, eliminate noise, and prevent the dropping of the grating lid due to damage to the mounting surface of the grating lid in the concrete side groove, and a grating lid used therefor Is an issue.

Moreover, it is not absolutely prohibited that water-permeable asphalt agglomerates enter the grating lid, and any structure that allows water to pass therethrough may be used. If necessary, a plurality of dedicated water passages may be formed. This grating lid is used when rainwater, etc. that has fallen on the road penetrates into the water-permeable asphalt laid on the road and flows from the asphalt to the concrete side groove side. It is for entering.

  The gutter unit according to claim 2 has a concrete lid corresponding portion formed by providing a step in the thickness direction of the rising portion to form a concrete lid containing space, and the rising portion has the same height plane. A step corresponding to the thickness of the grating lid is formed between the heights of both outer walls, and a grating lid corresponding portion provided with a detent for restraining the movement of the grating lid is continuously integrated.

Here, when the upper surface of both rising parts of the grating lid corresponding part of the concrete side groove is formed lower than the concrete cover corresponding part in accordance with the height dimension of the grating lid, when the grating lid is placed, The upper surface is made to coincide with the upper surfaces of both rising portions of the concrete lid corresponding portion of the concrete side groove.
In addition, the detent that restrains the movement of the grating lid provided in the concrete side groove may be simply a cylindrical projection member. However, if the tip is formed in a substantially conical shape, the positioning of the grating lid is determined. It becomes easy to insert the hole into the protruding member. The positioning of the grating lid is set by a detent provided in the concrete side groove.

And, the structure in which water outside the grating lid passes through the grating lid in a direction perpendicular to the connecting length direction of the concrete side groove and flows into the grating lid corresponding portion of the concrete side groove is made of water-permeable asphalt. Depending on the construction and the use for many years, a shape that can stably pass water from the side surface is required. It is not absolutely prohibited that water-permeable asphalt enters the grating lid, and any structure that allows water to pass therethrough may be used.
Furthermore, the surface shape of the leg member fixed to the lower surface of the grating lid is such that when the grating lid is placed in the concrete side groove, the contact surface of the grating lid is somewhere on the surface of the leg of the concrete side groove. As long as the surface shape is abutted at a plurality of locations, a curved surface shape including a shape obtained by dividing the cylinder into approximately 1/4 in the axial direction, a slope shape assumed from a triangle with one side as a base, and a planar shape assumed from a quadrangle Various surface shapes such as can be adopted.

The gutter unit according to claim 3 is configured such that a concrete lid corresponding portion formed with a concrete lid accommodating space at a predetermined rising portion height and the rising portion of the concrete lid corresponding portion have substantially the same height plane, In a side groove unit having a concrete side groove formed by continuously integrating a grating lid corresponding portion provided with a detent for restraining the movement of the grating lid, the grating lid is restrained from moving by the detent. The water outside the grating lid passes through the grating lid and flows into the lower portion of the grating lid in a direction perpendicular to the length direction of the concrete side groove.
Here, the concrete side groove in which the rising part of the concrete cover corresponding part and the grating cover corresponding part have the same height and is provided with a detent for restraining the movement of the grating cover is provided with a detent in the concrete side groove. Just by installing, the movement is restrained by the detent, and the water outside the grating lid passes through the grating lid in a direction perpendicular to the length direction of the concrete side groove and flows into the lower portion of the grating lid. Any grating lid structure may be used. Of course, the movement of the concrete lid may be any structure that can stop the movement in the accommodation space of the concrete lid corresponding portion, and here, the structure of the concrete lid corresponding portion is not questioned.
In addition, the structure in which water outside the grating lid passes through the grating lid and flows into the corresponding portion of the grating lid in a direction perpendicular to the length direction of the concrete side groove is when water-permeable asphalt is laid. In addition, any structure may be used as long as it allows water to pass stably from the side to the inside without clogging with water-permeable asphalt.

The gutter unit according to claim 5, wherein a structure in which water outside the grating lid flows through the grating lid and flows into the grating lid corresponding portion in a direction perpendicular to the length direction of the concrete gutter is laid on a road. Asphalt agglomerates are set so as not to enter. However, it is not absolutely prohibited that water-permeable asphalt agglomerates enter the grating lid, and any structure that allows water to pass therethrough may be used.

  In addition, it is necessary to appropriately set the shape and dimensions of the water passage of the grating lid when compared with the water-permeable asphalt agglomerates laid on the road. As the shape and dimensions of the water passage, a shape including an inverted U-shaped hole and a square hole having a size that does not allow water-permeable asphalt agglomerates to enter is preferable. In addition, as another shape of the water passage, even if water-permeable asphalt agglomerates enter or clogged up slightly, excessive force is applied to the water-permeable asphalt side when lifting the grating lid. For example, there are an inverted U-shaped slit shape and an inverted V-shaped shape that are open downward. As specific dimensions of the diameter and width of these water passage holes, if they are too small, they are likely to be clogged with foreign matters such as dust and dust, so the maximum value is considered as the maximum value in consideration of water-permeable asphalt agglomerates and their fluidity. It has been confirmed by the inventor that a value of about 20 mm or less should be applied.

It is possible to make a grating lid structure that flows into the tank.

Also, if the upper surface of both rising parts of concrete side grooves such as road side grooves is a mounting surface that is formed low in accordance with the height dimension of the grating lid, the upper surface corresponds to the concrete lid when the grating lid is mounted. What is necessary is just to match | combine with the upper surface of the concrete cover of a part, and the upper surface of the outer side of both the rising parts of the concrete side groove.
The structure in which water outside the grating lid flows in and out of the grating lid corresponding part in a direction perpendicular to the length direction of the concrete side groove is laid with water-permeable asphalt. Sometimes, the water-permeable asphalt agglomerates are not clogged, and any structure may be used as long as water can be stably passed from the side to the inside.

  The gutter unit according to claim 1 is configured such that the concrete gutter on which the grating lid is placed is installed on a road on which the permeable asphalt is laid, so that rainwater or the like that has penetrated into the permeable asphalt is It passes through and flows inward from the side surface of the grating lid, that is, drains into the concrete side groove through the grating lid. Further, according to the grating lid corresponding portion of the concrete side groove, the grating lid having the same dimensions is placed on the mounting surface formed so that the upper surfaces of both the rising portions of the concrete side groove are low, and both the rising portions of the concrete side groove Since the upper surface of the concrete cover and the upper surface of the concrete cover and the grating cover are on the same plane, safety can be ensured even when walking or cycling. In addition, since a detent for restricting the movement of the grating lid is provided on the mounting surface, the grating lid does not shift in position with respect to the concrete side groove. And by the detent that restrains the movement of the grating lid, the grating lid acts to suppress displacement, and even if a large force is applied from the upper surface of the grating lid, the concrete side groove side will accept it with its entire thickness Can be damaged.

According to the gutter unit of claim 2, the concrete gutter on which the grating lid is placed is installed on the road where the permeable asphalt is laid, so that rainwater or the like that has penetrated the permeable asphalt Through the water passage on the side of the grating lid that will be set lower than the upper surface on the outer wall side of both rising parts, and flows inward from the side of the grating lid, that is, into the concrete side groove via the grating lid. It is drained efficiently.
In addition, a detent for restraining the movement of the grating lid is provided on the mounting surface, and the detent for restraining the movement of the grating lid does not cause displacement of the grating lid with respect to the concrete side groove. And since the grating lid is placed on the grating lid corresponding part of the concrete side groove and the upper surface of both rising parts of the concrete lid corresponding part is the same plane, safety is ensured even if walking or biking it can. Furthermore, since a detent for restricting the movement of the grating lid is provided on the mounting surface, the grating lid does not shift in position with respect to the concrete side groove. Even if a large amount of force is applied from the top surface of the grating lid, the concrete side groove side can be received with its entire thickness even if a large amount of force is applied from the top surface of the grating lid by the detent that restrains the movement of the grating lid. And there is no damage. The leg member fixed to the lower surface of the grating lid is formed so as to include a surface shape that substantially follows the leg receiving surface formed at a position lower than the mounting surface on the inner wall side of both rising portions of the concrete side groove. When the leg member is placed on the leg receiving surface, the concrete side groove and the grating lid can be maintained in a stable fixed state.

In addition to any one of the effects, the nut and the bolt are screwed together, so the bolt and nut as a detent that restrains the movement of the grating lid firmly restrains the movement of the grating lid. Therefore, the opening side of the concrete side groove is firmly integrated, the relative movement of the grating lid and the concrete side groove is restricted, and the structure against the force in the direction of expanding the opening side of the concrete side groove becomes a structure. Even if force is applied, the concrete side groove side can be received with the entire thickness of the rising part, It does not generate the direction of the external force to widen the opening side of the groove, never or damaged cracked concrete gutter.
Moreover, even if foreign matter such as dust or dust is attached before the grating lid is placed, it is easy to drop and attachment is easy. Further, since the movement of the grating lid is firmly restrained, there is an effect that the occurrence of rattling noise can be prevented by eliminating the lifting.

  The structure in which water outside the grating lid flows into the grating lid corresponding part through the grating lid in a direction perpendicular to the length direction of the concrete side groove of the gutter unit according to claim 5 is laid on a road. In addition to the effect described in any one of claims 1 to 4, the asphalt agglomerates are set in a shape and size that do not become difficult to remove and become clogged. The effect of passing rainwater etc. from the water passage into the concrete gutter may be diminished, and even if the grating lid is removed from the concrete gutter after construction, the water permeable asphalt may be damaged. Therefore, it is easy to return the grating lid to its original position. It is possible to equity.

The grating lid attached to the concrete side groove in which the height of the rising portion of claim 6 is the same plane and is provided with a detent that restrains the relative movement with the concrete side groove is constrained to move by the detent, Water outside the grating lid in a direction perpendicular to the length direction of the concrete side groove passes through the grating lid, flows into the lower portion of the grating lid, and is discharged into the concrete side groove. .
Therefore, the structure in which water outside the grating lid flows through the grating lid into the corresponding portion of the grating lid in a direction perpendicular to the connecting direction of the concrete side groove is when water-permeable asphalt is laid. Water-permeable asphalt agglomerates can be stably passed from the side to the inside without clogging. In addition, a detent for restraining the movement of the grating lid is provided on the mounting surface, and the detent for restraining the movement of the grating lid does not cause displacement of the grating lid with respect to the concrete side groove. And since the detent | locking which restrains the movement of a grating lid is arrange | positioned on the mounting surface, a grating lid does not produce position shift with respect to a concrete side groove. The detent that restrains the movement of the grating lid acts to suppress the displacement of the grating lid, and even if a large force is applied from the upper surface of the grating lid, the concrete side groove side can be received with its entire thickness, causing damage. There is nothing to do.

  Next, regarding the laying situation of the water-permeable asphalt 50 on the road, FIG. 7 showing the case where the gutter unit 100 of the present embodiment is installed on the road, and the case where the conventional gutter unit 1 is installed on the road This will be described in comparison with FIG. Here, FIG. 7 is a partial cross-sectional perspective view showing a state in which rainwater flows from the road with respect to the gutter unit of FIG. Moreover, FIG. 22 shown for description of embodiment of this invention is a partial cross-sectional perspective view which shows the inflow state of the rainwater from a road with respect to the conventional gutter unit.

In FIG. 22, as described above, the rain that has fallen on the road surface once penetrates into the permeable asphalt 50. However, rainwater that has penetrated into the water-permeable asphalt 50 is blocked by the cast concrete layer 50A, and cannot flow into the concrete side groove 10 as it is even if it moves to the side groove unit 1 side through the water-permeable asphalt 50. Therefore, after reaching the surface of the water permeable asphalt 50 and overflowing, the concrete side groove 10 gets over the upper surface 13 of the rising portion 12 and flows into the concrete side groove 10.
On the other hand, in the embodiment of FIG. 7, the rain that has fallen on the road surface penetrates into the permeable asphalt 50 and is prevented from penetrating into the lower cast concrete layer 50A. 50 moves to the side groove unit 100 side. Then, the round hole 137 and the reverse U formed in the iron plate 136 with the water passage hole of the frame body 131 of the grating lid 130 fixed to the mounting surface 115 of both rising portions 112 of the concrete side groove 110 of the side groove unit 100. Rainwater passes through the hole 138 inward from the side surface and flows into the inner bottom surface 111 of the concrete side groove 110. Thus, when the gutter unit 100 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 water floats on the surface of the permeable asphalt 50. In particular, the forward visibility of the vehicle driver at night is improved.

  As described above, the side groove unit 100 of the present embodiment is configured by placing the concrete lid 120 and the grating lid 130 on the concrete side groove 110, and the grating lid corresponding portion 110B of the concrete side groove 110 is configured as follows. When the grating lid 130 having the same width dimension is placed on the placement surfaces 115 of the two rising portions 112, the upper surfaces 113 of the two rising portions 112 of the concrete lid corresponding portion 110A are flush with each other. A bolt 116 provided on the mounting surface 115 and a leg receiving surface 114 formed at a position lower than the mounting surface 115 in a direction parallel to the upper surface 113 on the inner wall side of both rising portions 112, and a grating. The lid 130 has a positioning hole 134 formed corresponding to the bolt 116 of the concrete side groove 110 and water outside the grating lid 130 passes through the grating lid 130 in a direction perpendicular to the length direction of the concrete side groove 110. And a surface that flows into the grating lid corresponding portion 110B and a surface that is fixedly attached to the lower surface of the grating lid 130 and substantially abuts against the leg receiving surfaces 114 of both rising portions 112 when placed in the concrete side groove 110. A leg member 135 having a shape is provided.

That is, the concrete side groove 110 on which the grating lid 130 is placed is installed on the road where the water permeable asphalt 50 is laid, so that rainwater or the like that has permeated into the water permeable asphalt 50 can be removed from both the concrete side grooves 110. Through the round hole 137 and the reverse U-shaped hole 138 formed in the iron plate 136 with a water passage hole of the frame 131 of the grating lid 130 to be set lower than the upper surface 113 of the rising portion 112, the grating lid 130 Inflow from the side surface of the iron plate with water passage 136 to the inside can be satisfactorily performed, that is, drained into the concrete side groove 110 efficiently through the iron plate with water hole 136 of the frame 131 of the grating lid 130.
Further, a grating lid 130 having the same width in the thickness direction of the two rising portions 112 is mounted on the mounting surface 115 formed lower than the upper surfaces 113 of the two rising portions 112 of the concrete side groove 110. Since the upper surface 113 of the rising portion 112, the upper surface of the grating lid 130, and the concrete lid 120 have substantially the same plane, safety can be ensured even when walking or cycling.
The mounting surface 115 is provided with a bolt 116, and the positioning hole 134 drilled in the grating lid 130 is inserted into the bolt 116, so that the grating lid 130 is displaced with respect to the concrete side groove 110. It does not occur. Since the grating lid 130 is fixed to the bolt 116, the proof stress in the direction in which the concrete side groove 110 is expanded is increased, and even if a large force is applied from the upper surface of the grating lid 130, the concrete side groove 110 applies both forces. The force is distributed by being received by the entire surface of the mounting surface 115 and the leg receiving surface 114 of the rising portion 112, and the concrete side groove 110 is hardly damaged, and naturally, the grating lid 130 can be prevented from falling off.

Further, the projecting member of the concrete side groove 110 in the side groove unit 100 of the present embodiment is a bolt 116 having a threaded portion, and after the positioning hole 134 of the grating lid 130 is inserted, a nut 119 is attached to the bolt 116. The grating lid 130 is fixed to the placement surface 115 of the concrete side groove 110 by being screwed together.
As a result, the grating lid 130 with respect to the concrete side groove 110 is completely prevented not only from being displaced but also from rattling. In this case, the frame 131 of the grating lid 130 is supported by the mounting surfaces 115 of both rising portions 112 of the concrete side groove 110, and at the same time, the leg member 135 of the grating lid 130 is placed on the leg receiving surface 114 of the concrete side groove 110. Therefore, since the grating lid 130 is fixed to the bolt 116, the strength in the direction of expanding the concrete side groove 110 is high. It is strengthened by the lid 130. That is, since the grating lid 130 is fixed to the bolt 116 of the concrete side groove 110 through the positioning hole 134, the strength can be increased even against an external force that causes both rising portions 112 of the concrete side groove 110 to open outward. As a result, the concrete side grooves 110 are effective in preventing cracks.

And the round hole 137 and the reverse U-shaped hole 138 as the water flow path of the grating lid 130 in the side groove unit 100 of the present embodiment are the water permeability laid on the road after the grating lid 130 is installed on the road together with the concrete side groove 110. The asphalt 50 is set to have a shape and dimensions that do not clog with entering.
In other words, after the gutter unit 100 is installed on the road, the water-permeable asphalt 50 is laid on the road so that the water-permeable asphalt 50 does not enter or become clogged. The round hole 137 and the inverted U-shaped hole 138 of the grating lid 130 are set to a predetermined shape and a predetermined dimension. Thereby, even if the grating lid 130 is removed for cleaning or the like in the concrete side groove 110 of the side groove unit 100 after laying the water permeable asphalt 50 on the road, the water passage hole of the frame 131 of the grating lid 130 is removed. A part of the water-permeable asphalt 50 adjacent to the iron plate 136 is not lifted and damaged. Then, after cleaning or the like, the grating lid 130 can be returned to the original position of the concrete side groove 110 of the side groove unit 100 without any problem.
Further, the round hole 137 and the reverse U-shaped hole 138 as the water passage of the grating lid 130 in the side groove unit 100 of the present embodiment are formed in the iron plate 136 with the water hole of the frame 131 of the grating lid 130. However, when the present invention is carried out, the frame 131 or the iron plate 136 with a water passage hole is not necessarily required. After the end of the grating lid 130 is installed on the road together with the concrete side groove 110, Any shape and size may be used as long as the permeable asphalt 50 to be laid does not enter or become clogged.

Next, a modification of the leg receiving surface of the concrete side groove of the side groove unit in the above-described embodiment will be described with reference to FIGS.

A concrete lid 120 formed with a convex curved surface that substantially contacts the concave curved surface 114 is placed. In this case, both end edges of the lower surface of the concrete lid 120 corresponding to the leg receiving surface 114 are formed as convex curved surfaces. Further, the grating lid corresponding portion 110B of the concrete side groove 110 is configured by placing a leg member 135 of the grating lid 130 formed with a convex curved surface that substantially contacts the concave curved surface of the leg receiving surface 114. In this case, both end edges of the lower surface of the concrete lid 120 corresponding to the leg receiving surface 114 are formed as convex curved surfaces.

On the other hand, as shown in FIG. 8 as a first modified example, the leg receiving surface 114a of the concrete side groove 110 may be formed of an inclined surface having a predetermined angle. In this case, the concrete lid corresponding portion 110A employs a concrete lid 120a having inclined surfaces in which both end edges of the lower surface corresponding to the leg receiving surface 114a have a predetermined angle in order to suppress generation of sound due to rattling. The Further, the grating lid corresponding portion 110B employs a grating lid 130a in which a leg member 135a having a lower surface having an inclined surface corresponding to the leg receiving surface 114a is fixed. At this time, the nut 119 is screwed to the bolt 116 of the concrete side groove 110, whereby the grating lid 130a is fixed to the placement surface 115 of the concrete side groove 110, and generation of sound due to rattling can be suppressed.
Further, as shown in FIG. 9, the leg receiving surface 114 b of the concrete side groove 110 may be a structure having a flat surface as shown in a second modification. In this case, the grating lid corresponding part 110B employs a grating lid 130b in which a leg member 135b having a flat bottom surface is fixed correspondingly to the leg receiving surface 114b, and similarly, the concrete lid corresponding part 110A. Then, a concrete lid 120b is adopted in which both end edges of the lower surface are flat surfaces corresponding to the leg receiving surface 114b.
