Description

The present invention relates to a gutter block that is buried in a side portion of a road or the like and drains rainwater or snowmelt water that has fallen on a road surface.
In particular, the present invention relates to a side groove block in which a water guide long groove is formed on a side surface of the side groove block in order to guide water penetrating from the road surface to the inside.

Conventionally, the side groove block shown in FIG. 9 is known as a side groove block in which a water guide long groove is formed on the side surface of the side groove block in order to guide water that has permeated the road (see Patent Document 1).
As shown in the drawing, the concrete side groove block 1 is constructed on a road by being connected in plural along the longitudinal direction via a connecting fitting 2.

A drainage channel 3 is formed inside the side groove block 1 along the longitudinal direction, and rainwater or the like accumulated on the road surface flows into the drainage channel 3.
The upper surface 1a of the gutter block 1 is a tapered surface that gradually decreases from the one side surface 1b side toward the other side surface 1c side, and rainwater present on the upper surface 1a is guided from the one side surface 1b side to the other side surface 1c side.

A pair of water guide long grooves 1d and 1e are formed on one side surface 1b of the side groove block 1 along the longitudinal direction, and the water guide long grooves 1d and 1e guide water that has permeated the road.
Further, on one side surface 1b of the side groove block 1, drainage fittings 4 having drainage holes are provided at regular intervals so that water guided from the water guide long grooves 1d and 1e flows into the drainage channel 3. .

As shown in FIG. 10, the drainage fitting 4 is formed with a water guide hole 1f having a long and narrow cross-sectional shape on one side surface 1b, and a rectangular shallow recess 1g is formed around the opening of the water guide hole 1f. ing.
The drainage fitting 4 is formed with a plurality of elongated holes 4b, and both sides near the center in the longitudinal direction are bent as vertical plate pieces 4a.
The drainage metal fitting 4 is attached to the side groove block 1 by fitting the bent plate piece 4a into the water guide hole 1f and further fitting the back surface of the drainage metal fitting 4 into contact with the recess 1g.

FIG. 11 shows a specific construction example of the gutter block 1 on the road.
As shown in the figure, the gutter block 1 is embedded along the side of the road.
A road 5 is constructed on one side surface 1 b of the gutter block 1.
The roadbed 6 is located below the water guide long groove 1e, and an impermeable pavement 7 is provided thereon, and the upper surface thereof is located at the lower end of the water guide long groove 1d.
A water-permeable pavement 8 is provided on the water-impermeable pavement 7, and the upper surface thereof is located at the upper end of the one side surface 1b.

Now, in the road 5 in which such a gutter block 1 is laid, rainwater that has fallen on the road penetrates into the permeable pavement 8, reaches the upper surface of the impermeable pavement 7, and travels along the upper surface of the gutter block. Led to 1.
The rainwater guided to the side groove block 1 is guided to the water guide hole 1f through the water guide long groove 1d, flows into the drainage channel 3 from the water guide hole 1f, and is drained.
(Also, a part of the side groove block 1 connected in the longitudinal direction is formed with a window portion in which a fence is fitted on the upper surface 1a so that water accumulated on the side groove block 1 can be drained. )

FIG. 12 shows another construction example of the gutter block 1 on the road.
In this road 5A, a step 7a is formed in the water-impermeable pavement 7 in the vicinity of one side 1b of the side groove block 1, and the height of the step 7a is located at the lower end of the water guide long groove 1e.
With such a configuration, it is possible to send rainwater that has traveled along the upper surface of the impermeable pavement 7 into the water guide long groove 1e.

FIG. 13 shows another construction example of the gutter block 1 on the road.
In this road 5 </ b> B, the water-permeable pavement 8 is not formed, and a water guide gap 14 is formed between the water-impermeable pavement 7 and the gutter block 1.
The bottom of the water guide gap 14 is located at the lower end of the water guide long groove 1d.
That is, the upper surface of the roadbed 6 is located at the lower end of the water guide long groove 1d.

  With such a structure, rainwater on the road 5B enters the water guide gap 14 and the water guide long groove 1d, is guided by the water guide gap 14 and the water guide long groove 1d, and is discharged from the water guide hole 1f to the drainage channel 3.

As described above, in the construction of the gutter block 1 on the road, there is an advantage that water flows relatively efficiently because a drainage path is formed.
That is, water is smoothly guided from the impervious pavement 7 to the water guide long grooves 1d and 1e.
However, since the partition space for passing water through the drainage fitting 4 from the water guide long grooves 1d and 1e of the side groove block 1 to the water introduction hole 1f is not secured, the water guide long grooves 1d and 1e reach the drainage fitting 4. In this case, there is a drawback that the passage of water becomes worse.

In particular, the recessed portion 1g is formed for attaching the drainage fitting 4, and it is not possible to secure a sufficient area for communicating with the water guide hole 1f through which water passes through the drainage fitting itself.
Thus, in the conventional gutter block 1, the drainage of the drainage fitting 4 is not always satisfactory.

Utility Model Registration No. 3047285

The present invention has been made on the basis of such background technology, and has been made to overcome the above-described problems of the background technology.
That is, an object of the present invention is to provide a gutter block with excellent drainage in a drainage fitting.

  Thus, as a result of earnest research on the background of such problems, the present inventor formed a horizontally long groove in the drainage fitting, and connected it to the water guide length groove of the side groove block, so that the drainage in the drainage fitting was significantly reduced. Based on this finding, the present invention has been completed.

  That is, according to the present invention, (1) a drainage channel is formed by a pair of side walls and an upper wall connecting the side walls, and a drainage fitting having a drainage hole is attached to the upper part of the sidewalls. It is a side groove block in which a space leading to the drainage channel is formed on the back side of the metal fitting, and a water guide long groove is formed on the side wall, a laterally long groove is formed on the drainage metal fitting, Exists in the gutter block attached to communicate with each other.

  Further, the present invention resides in (2) a side groove block in which a drainage hole is formed in the laterally long groove.

  In this way, when the water guide long groove communicates with the horizontally long groove, when rainwater or the like that has fallen on the ground penetrates the ground and reaches the water guide long groove, it smoothly travels along the water guide long groove to the horizontal groove of the drainage fitting, and further drain holes are formed. It will drain through the gutter block.

  In addition, since the drainage fitting and the cotter are attached to the mold by bolts or screws when the side groove block is formed, a void is formed on the back side of the drainage fitting, but in the present invention, since the laterally elongated groove is formed in the drainage fitting, the cotter Thus, the conventional problem that the relative position with respect to the drainage fitting is displaced due to vibration from the mold vibrator during molding and compacting of the concrete is avoided.

Therefore, it is possible to accurately prevent the drainage fitting from being lifted from the formwork.
Therefore, the drainage fitting can be attached to the position as designed in the side groove block, and a good side groove block can be provided.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 shows a gutter block according to an embodiment of the present invention.
The side groove block 16 is made of, for example, concrete and has an upper surface wall 16a and a pair of side walls 16b and 16c.
A portion surrounded by the upper wall 16a and the pair of side walls 16b and 16c is a drainage channel.
A water guide long groove 16d is formed in the side wall 16b of the side groove block 16 along the longitudinal direction thereof. The water guide long groove 16d guides water that has permeated the road toward the drainage fitting 17, that is, guides water.

A plurality of rising grooves 16e are formed at intervals in the side wall 16b and communicated with the water guide long groove 16d.
In this way, by forming the plurality of rising grooves 16e on the side wall 16b, the water collecting ability can be further enhanced as will be described later.
A drainage fitting 17 having a drainage hole is attached to the upper portion of the side wall 16 b, and a void communicating with the drainage channel is formed on the back side of the drainage fitting 17.

A rectangular through hole 16a1 is formed in the upper surface wall 16a, and a side groove cover 18 is placed in the through hole 16a1.
The notch 18a formed in the portion adjacent to the drainage fitting 17 of the side groove lid 18 forms a large flow path 23 (described in FIG. 6) when the side groove lid 18 is fitted into the side groove block 16.

FIG. 2 shows details of the drainage fitting 17.
The drainage fitting 17 is bent in an L shape, and the short side of the L shape is located on the upper surface wall 16a side, and the long side of the L shape is located on the side wall 16b side.
The short side short piece 17a and the upper surface wall 16a are flush with each other, and the long side long piece 17b and the side wall 16b are similarly flush with each other.

The short piece 17a and the long piece 17b are respectively provided with a protrusion 17a1 and a protrusion 17b1, and are embedded in the concrete, so that the drainage fitting 17 is securely fixed to the side groove block 16.
A plurality of (here, five) drain holes 17c are formed in the short piece 17a, and rainwater that falls mainly on the upper surface wall 16a of the side groove block 16 or the road surface through the drain holes 17c is directly entered into the side groove block 16. Drain.

A plurality of round drain holes 17e are also formed in the long piece 17b, and the water that has permeated below the road surface is mainly drained.
The long piece 17b is formed with a trapezoidal laterally long groove 17d communicating with the water guide long groove 16d, and a plurality of the drain holes 17e are formed in the laterally long groove 17d.
When the laterally long groove 17d exists, the water collection area becomes larger than when there is no groove, and the drainage capacity (drainage, etc.) of the drainage fitting 17 can be increased.

FIG. 3 is a developed view showing the relationship between the mold 19 for forming the side groove block 16, the drainage fitting 17, and the cotter 20 for forming the void 22 on the back side of the drainage fitting 17. .
A bolt hole 19 a for inserting the mounting bolt 21, a fool hole 17 f, and a female screw hole 20 a are formed in the mold 19, the drainage fitting 17, and the cotter 20, respectively.
Among these, the fool hole 17 f formed in the drainage fitting 17 has a diameter larger than that of the mounting bolt 21, and ensures a degree of freedom in aligning the drainage fitting 17 with the mold frame 19.

The cotter 20 is formed with a female screw hole 20a for screwing the mounting bolt 21 and a trapezoidal groove 20b into which the laterally long groove 17d of the drainage fitting 17 is fitted.
Then, the mounting bolt 21 is inserted into the bolt hole 19a from the outside of the mold 19, and the mounting bolt 21 is further inserted into the fool hole 17f of the drainage fitting 17, and finally screwed into the female screw hole 20a of the cotter 20 and tightened. Thus, the drainage fitting 17 and the cotter 20 are accurately attached to the mold 19.

FIG. 4 shows a state in which the drainage fitting 17 and the cotter 20 are assembled to the mold 19.
In this way, by fitting the concave portion of the trapezoidal horizontally long groove 17d into the trapezoidal groove 20b of the cotter 20, the drainage fitting 17 and the cotter 20 are securely connected in a close contact state, and are trapezoidal. Therefore, after demolding, they can be easily fitted and removed from each other.
Then, the relative position between the drainage fitting 17 and the cotter 20 is changed due to the displacement of the flaw hole 17f of the drainage fitting 17 from the mounting bolt 21 due to vibration from the mold vibrator during compaction of the concrete during molding. There is no such thing.

Therefore, it is possible to prevent the concrete from entering between the drainage fitting 17 and the cotter 20 and closing the drainage holes 17c and 17e.
Further, the shape of the side groove block 16 can be surely made constant, and the side groove block 16 as designed can be formed.

In addition, the vibration of the concrete in the mold 19 before solidification is performed in a sense that the concrete in the mold 19 is surely filled. Specifically, the mold vibrator is attached to the outer surface of the mold 19. It is performed by attaching or operating the mold vibration machine by hand to give vibration to the mold 19.
Now, after the concrete is solidified, the mounting bolts 21 are removed from the mold 19 and the side groove block 16 is released from the mold 19.

Next, when the cotter 20 fitted to the drainage fitting 17 is removed, a void 22 (see FIG. 6) is formed in that portion.
Due to the presence of the void 22, even if gravel or the like enters the drainage fitting 17, it is avoided that the back side is clogged.

Next, the flow when rainwater or the like is collected in the drainage channel in the gutter block 16 will be described with reference to FIGS.
6 is a cross-sectional view taken along the line AA in FIG. 5, and FIG. 7 is a cross-sectional view taken along the line BB in FIG.
When rain 9 falls on the road 10, rainwater penetrates through the permeable pavement 11 and further accumulates on the upper surface of the impermeable pavement 13 formed on the roadbed 12.
The accumulated rainwater is guided along this upper surface to the drainage fitting side as indicated by an arrow.
Since the lower end of the water guide long groove 16d of the drainage fitting 17 is located at the same height as the upper surface of the water-impermeable pavement 13, the rainwater that has moved on the water-impermeable pavement 13 is collected in the water guide long groove 16d.

Rainwater that has reached the water guide long groove 16d is guided along the longitudinal direction of the water guide long groove 16d and reaches the laterally long groove 17d of the drainage fitting 17 that is in communication therewith.
Then, the rainwater flows into the void 22 formed on the back side of the drainage fitting 17 through the drainage hole 17e formed in the laterally long groove 17d.
Furthermore, the rainwater is discharged to the drainage channel 24 through the flow path 23 formed by the upper surface wall 16a and the side wall 16b.

Here, it is preferable that the lower ends of the water guide long groove 16d and the horizontal long groove 17d are formed at a position of 4 to 10 cm from the upper surface of the upper surface wall 16a.
This range of 4 to 10 cm is a normal position range where the water-permeable pavement 11 is applied, and the upper surface of the water-impermeable pavement 13 preferably corresponds to the position where the water guide long groove 16d is formed.
In other words, it can be said that the water guide long groove 16d and the horizontal long groove 17d also serve as marks as a backfill position of the water-permeable pavement 11.

Moreover, since the water-permeable pavement 11 bites into the water guide long groove 16d and the laterally long groove 17d, the road surface around the side groove block 16 can be prevented from sinking.
The above has been described in the case where the lower end of the water guide long groove 16d is positioned at the same height as the upper surface of the impermeable pavement 13. However, an error occurs in the construction, and the upper surface of the impermeable pavement 13 is positioned somewhat above. It may happen.
In this case, rainwater collected on the upper surface of the impermeable pavement 13 is guided to the water guide long groove 16d through the rising groove 16e.
FIG. 7 shows a state in which it flows down to the water guide long groove 16d through the rising groove 16e.

(Modification)
FIG. 8 shows a modification of the side groove block according to the embodiment of the present invention.
The rising groove 16f of the side groove block 16A of this modification is different in that it is formed longer than the rising groove 16e of the side groove block 16 and opens to the upper surface wall 16a.
Rainwater is also drained downward from the opened portion.

Although the present invention has been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that other various modifications are possible without departing from the essence thereof.
In the above-described embodiment, the example in which the single water guide long groove 16d is formed in the side groove block 16 has been described. However, a plurality of the long long grooves 17d of the drainage fitting 17 may be formed in this case. It is preferable that

Further, the rising groove 16e shown in the embodiment may not be formed.
Furthermore, in the above-described embodiment, the example in which the drainage fitting 17 and the cotter 20 are attached to the mold 19 using the mounting bolts 21 has been described. For example, a mounting pin can also be used.
Further, the cotter 20 and the mold 19 may be made of metal and magnetically attached to the drainage fitting 17.
