Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[Overall configuration of drainage equipment]
FIG. 1 is a perspective view showing an example of a drainage facility using a gutter block 1 according to an embodiment of the present invention.
As shown in FIG. 1, this drainage facility includes a side groove section 3 in which a side groove block 1 is continuously embedded along the longitudinal direction A of the road 2, and a buttock section interposed between the side groove sections 3. 4 is provided.

The side groove block 1 of the present embodiment has both a function as an electric wire common groove capable of storing cables 5 together and a function as a side groove for drainage, and is along the longitudinal direction A of the road 2. A plurality of burials are continuously embedded on the left and right sides of the road.
A road 2 shown in FIG. 1 is a small paved road having a relatively small width and having a merging sewer pipe 6 in the center in the transverse direction. Therefore, each side groove block 1 installed on the side of the road is arranged in a state where the outer edge in the width direction of the side groove block 1 coincides with the public-private boundary line B in order to shorten the drawing distance of the cable 5A to the house 7 as much as possible. ing.

As shown in FIG. 1, the cables 5 housed in the gutter block 1 include various cables (for example, low-voltage or high-voltage power lines, telephone lines, optical fibers, etc.) that serve as lifelines for residents of the house 7. Communication line) 5A.
However, when there is a margin in the size of the storage space 18 to be described later, the cables 5 can include water and sewage piping and gas piping, and can also be stored alone. In addition, the “cables” referred to in this specification is used not only to describe each cable 5A itself, but also to include the protective tube 5B when the cable 5A is inserted through the protective tube 5B. doing.

  In the example of FIG. 1, a “communication trunk line” protective tube 5B is accommodated in the side groove block 1 of the left side groove section 3, and a “high voltage power line” protective tube 5B is disposed in the side groove block 1 of the right side groove section 3. It is stored.

[Configuration of side groove block]
2A is a perspective view of the side groove block, and FIG. 2B is a cross-sectional view thereof.
As shown in FIG. 2, the side groove block 1 of the present embodiment includes a block main body 11 having a cross section of an open channel, a bottom plate member 12 formed in a substantially flat plate shape, and a lid member that closes an upper open portion of the block main body 11. 13.
Among these, the block main body 11 is made of precast concrete, and has a right and left side wall part 14 and a bottom wall part 15 that connects the lower end parts thereof, and a concrete block having a substantially U-shaped cross section with the upper part opened. Consists of the body.

The block body 11 of the present embodiment has a rectangular cross section whose cross section height is larger than the cross section width, the cross section width is set in the range of 300 to 600 mm, and the cross section height is in the range of 450 to 850 mm. Is set to
The length of the block main body 11 is set in a range of 1000 to 4000 mm, and the length of the lid member 13 is generally about 500 mm. However, the length of the block main body 11 is not particularly limited. Further, the length of the bottom plate member 12 is preferably about 1000 mm because it can be constructed manually, but this can also be set regardless of the length of the block body 11.

Each side wall portion 14 of the block body 11 has a flat outer surface, but a step portion 16 is formed at a substantially central portion in the vertical direction of the inner surface (see FIG. 2A). The step portion 16 extends along the longitudinal direction of the block main body 11, so that the cross-sectional thickness of the upper half portion of the side wall portion 14 is slightly smaller than the cross-sectional thickness of the lower half portion thereof. ing.
Of the inner cross section of the block body 11 surrounded by the side wall portions 14 and the bottom wall portion 15, the upper portion above the step portion 16 is a drainage space (drainage channel) 17. A lower lower portion serves as a storage space 18 for the cables 5.

Further, on the inner surfaces of the side wall portions 14 of the block main body 11, lid hooking ribs 19 that support both edges in the width direction of the lid member 13 are extended along the longitudinal direction of the block main body 11.
The lid hooking rib 19 is interrupted at a predetermined position in the longitudinal direction of the block main body 11, and a notch (not shown) at the interrupted position is a hooking tool 21 (used when the bottom plate member 12 is mounted. This is the escape portion of FIG.
The width dimension of the bottom plate member 12 is set to a dimension that is smaller than the opening width of the block body 11 but larger than the interval in the width direction between the left and right step portions 16.

For this reason, for example, as shown in FIG. 2 (b), the other end edge of the bottom plate member 12 is attached to the other end edge with the other end edge in a state where the one end edge in the width direction is placed on one stepped portion 16. By gradually placing it on the other stepped portion 16, the bottom plate member 12 can be attached to the midway portion in the vertical direction of the inner hollow section of the block body 11.
When the bottom plate member 12 is thus mounted, the drainage channel 17 is formed above the bottom plate member 12 in the inner cross section of the block main body 11, and the storage space 18 for the cables 5 is secured in the lower portion. It will be.

As shown in FIG. 2A, a rubber seal member 24 that is in contact with the back surface of the edge portion of the bottom plate member 12 is attached to the upper surface of the step portion 16. Water leakage from the drainage channel 17 formed on the upper surface to the storage space 18 below is prevented.
The seal member 24 may be attached to the lower surface of the bottom plate member 12 instead of the upper surface of the step portion 16. Further, by attaching the seal member 24 to both edge surfaces (cut end surfaces) of the bottom plate member 12 in the width direction, water is stopped between the edge portion of the bottom plate member 12 and the wall portion immediately above the step portion 16 in the side wall portion 14. May be. Moreover, although not shown in figure, the edge part of each baseplate member 12 arranged in parallel by the longitudinal direction is watertightly connected with the sealing tape which consists of butyl rubber etc., for example.

[Effect of gutter block]
According to the side groove block 1 of the present embodiment, the portion below the bottom plate member 12 in the inner hollow cross section of the block main body 11 is the storage space 18 for the cables 5. Compared with the case where the storage space is provided (in the case of Patent Documents 1 and 2), a larger cross section of the storage space 18 can be secured. Therefore, the work of laying the cables 5 (the cable 5A itself or its protective tube 5B) in the storage space 18 becomes easier.

Further, according to the side groove block 1 of the present embodiment, the drain plate 17 is cleaned and then the bottom plate member 12 is removed from the block body 11, so that the storage space 18 of the cables 5 can be easily obtained even after the completion of the construction of the side groove block 1. Can be opened.
For this reason, when adding or exchanging the cable 5A or the protective tube 5B, it is not necessary to dig up the ground on the side of the block main body 11, and the addition or replacement of the cables 5 can be easily handled.

Further, according to the side groove block 1 of the present embodiment, the cables 5 are stored in the storage space 18 below the bottom plate member 12 mounted on the inner hollow section of the block main body 11, so that the drainage channel 17 is cleaned. When doing this, the cables 5 do not get in the way.
For this reason, maintenance work such as cleaning for removing sludge on the drainage channel 17 can be easily performed.

Furthermore, according to the side groove block 1 of the present embodiment, the stepped portion 16 that supports the left and right edges of the bottom plate member 12 is integrated along the longitudinal direction of the block body 11 on the inner surface of the side wall portion 14 of the block body 11. Is formed.
For this reason, for example, compared with a case where a bracket 61 (see FIG. 11) extending in the longitudinal direction of the block body 11 is attached to the side wall portion 14 and a stepped portion supporting the bottom plate member 12 is created later, the material cost and the impact are reduced. The time required for installation can be reduced, and the manufacturing cost of the side groove block 1 can be reduced.

Further, according to the side groove block 1 of the present embodiment, the gap between the stepped portion 16 and the bottom plate member 12 is watertightly stopped by the seal member 24, and the end portions in the longitudinal direction of the bottom plate member 12 are watertightly sealed with a seal tape. By stopping the water, leakage from the drainage channel 17 to the lower storage space 18 is prevented as much as possible.
For this reason, there exists an advantage that the deterioration of the said cables 5 accompanying the water leak from the drainage channel 17 reaching the storage space 18 of the cables 5 can be suppressed as much as possible.

[Components of the buttocks section (Part 1)]
FIG. 3A to FIG. 3D show a change block 31 and a water collecting basin 32 which are constituent members of the buttock section 4 (see FIG. 1).
3A is a plan view of the change block 31 and the water collecting basin 32, FIG. 3B is a perspective view of the direction changing member 33, and FIG. 3C is a longitudinal sectional view of the water basin 32, FIG. 3 (d) is a cross-sectional view of the change block 31 and the catchment basin 32.

As shown in FIG. 3, the change block 31 includes a block main body 35 having the same cross-sectional shape as the block main body 11 of the side groove block 1 and a bottom plate member 36 having the same cross-sectional shape as the bottom plate member 12.
When the bottom plate member 36 is mounted inside the block main body 35, the inside is partitioned into two upper and lower stages of an upper space 37 and a lower space 38. In this case, the upper space 37 has the same cross-sectional shape as the drainage channel 17 of the side groove block 1. Thus, the lower space 38 has the same cross-sectional shape as the storage space 18 of the side groove block 1.

Therefore, when the change block 31 is concentrically connected to the end of an arbitrary side groove block 1, the upper space 37 of the change block 31 communicates with the drainage channel 17 of the side groove block 1, and the lower space 38 is the storage space for the side groove block 1. 18 communicates.
The block main body 35 of the change block 31 is formed with a drain port 39 in the side wall portion on the center side of the road, and the drainage that has flowed into the upper space 37 is supplied to the drain port 39 in the upper space 37 of the change block 31. A direction changing member 33 for guiding is provided.

For example, as shown in FIG. 3 (b), the direction changing member 33 is made of a block body or a plate material having a concave curved surface for approximately a quarter of a round, and the curvature radius of the concave curved surface is the upper space 37. The dimension is substantially equivalent to the cross-sectional width.
Further, the direction changing member 33 is housed in the upper space 37 in a state where the concave curved surface is desired for both the entrance of the upper space 37 and the drain port 39. For this reason, as shown by the thick arrows in FIG. 3, when the drainage flows from the entrance of the upper space 37, it strikes the concave curved surface and is turned 90 degrees toward the center of the road to reach the drainage port 39.

Accordingly, when the change block 31 is connected to the end portion of the side groove block 1, the upper space 37 of the change block 31 allows the drainage flowing in the longitudinal direction of the road flowing in from the drainage channel 17 of the side groove block 1 to pass through the center of the road by the direction change member 33. The function to change to the side is demonstrated.
On the other hand, in the case of the lower space 38 of the change block 31, the cables 5 inside the storage space 18 are bent because they communicate straight in the longitudinal direction and are not provided with the direction change member 33. It has the function which can be passed as it is.

The drainage basin 32 includes a box body 40. Although the shape and dimensions of the box body 40 can be arbitrarily designed, in this embodiment, the change block 31 has substantially the same cross-sectional shape as the block body 35 and the longitudinal dimension is larger than that of the block body 35. Yes. A water collection port 41 is formed in the side wall portion of the box body 40, and the side wall portions of the box body 40 and the block body 35 are connected to each other in a superposed manner so that the water collection port 41 and the drain port 39 coincide with each other. Is done.
For this reason, the wastewater whose direction is changed to the center of the road in the upper space 37 is temporarily stored in the water collection space in the water collection tank 32 through the water collection port 41.

  In the example shown in FIG. 3A, the grating is fitted into the upper end opening of the block main body 35 of the change block 31 and the box main body 40 of the catchment basin 32. You may decide to insert in a part.

[Configuration example of the buttocks section (part 1)]
FIGS. 4A and 4B are plan views showing a configuration example of the buttock section 4 using the change block 31 and the catchment basin 32. FIG.
Among these, FIG. 4A shows a case where there are two change blocks 31 and two catchment basins 32. As shown in the figure, in the configuration example of the flange section 4, change blocks 31 and 31 are connected to the side groove block 1 at the end of the two side groove sections 3 and 3 separated by the cable flange 34, respectively. Each change block 31, 31 is connected to a cable rod 34, respectively.

The cable rod 34 is also referred to as a so-called joint groove special portion, and has a size corresponding to, for example, a handhole or a manhole. In some cases, a pole 34A (see FIG. 4B) is provided on the upper surface or side surface of the cable rod 34, or a communication relay device or transformer is provided inside the rod.
The side groove block 1, the change block 31, and the cable rod 34 are all arranged with their outer edges in the width direction aligned with the public-private boundary line B. On the other hand, the water collecting basin 32 is disposed at a position offset to the center of the road of the change block 31 (the lower side in FIG. 4).

According to the drainage facility of the present embodiment, the change block 31 located on the extension of the side groove section 3 has the upper space 37 that communicates with the drainage channel 17 of the side groove block 1 and changes the direction of drainage to the center of the road. Therefore, as shown in FIG. 4A, the water collecting basins 32 and 32 for collecting the drainage from the upper space 37 can be disposed at positions offset to the center of the road in the side groove section 3.
For this reason, since the water collecting basin 32 does not interfere with the storage space 18 of the side groove block 1, there is no need to bypass the cables 5 outside the side groove block 1 in the section where the water collecting basin 32 is installed. Laying work can be easily performed.

Moreover, according to the drainage equipment of this embodiment, the change block 31 located on the extension of the side groove section 3 can be passed through the storage space 18 of the side groove block 1 without bending the cables 5. Since the lower space 38 is provided, the cable rod 34 for receiving the cables 5 passing through the lower space 38 can be disposed on the extension of the side groove section 3 as shown in FIG.
For this reason, since the cables 5 in the side groove block 1 can be extended to the cable rod 34 without being bent through the lower space 38 of the change block 31, the cables 5 are connected to the side groove block 1 in the section where the cable rod 34 is installed. It is not necessary to make a detour to the outside of the cable, and the cable 5 can be easily laid.

  The direction changing member 33 is a member that prevents waste and sludge from accumulating at the terminal end of the side groove section 3 by guiding the drainage from the side groove section 3 to the drainage basin 32 as smoothly as possible. It is not always necessary to provide in the upper space 37 of the change block 31.

On the other hand, FIG. 4B shows a case where there is one change block 31 and one catchment basin 32. As shown in the figure, in the configuration example of the buttock section 4, the changed block 31 is connected only to the side groove block 1 at the end of the one side groove section 3, and is offset to the road center side of the changed block 31. A water collecting pad 32 is arranged.
Therefore, also in the case of FIG. 4B, the water collecting basin 32 does not interfere with the storage space 18 of the side groove block 1, so that the cables 5 are detoured outside the side groove block 1 in the section where the water collecting basin 32 is installed. There is no need and the effect that the installation work of the cables 5 can be performed easily is obtained.

In the configuration example of FIG. 4B, the cable rod 34 is divided into two large and small ones, and a power pole 34A is provided on the upper surface of the right cable rod 34.
Further, in FIG. 4, reference numeral 42 denotes a transverse drain pipe connected to the catchment basin 32, and the drain pipe 42 communicates with the combined sewer pipe 6 (see FIG. 1). Further, reference numeral 43 denotes a protective tube branched from the cable rod 34 and extending in the transverse direction.

FIG. 5 is a plan view of another configuration example of the buttock section 4 using the change block 31 and the catchment basin 32.
The configuration example of the buttock section 4 in FIG. 5 is the same as that in FIG. 4A in that the change blocks 31 and 31 and the catchment basins 32 and 32 are provided on both sides in the longitudinal direction of the cable ridge 34, respectively. The two water collecting basins 32, 32 are different from the case of FIG. 4A in that water is connected by a small water channel 44 extending in the longitudinal direction along the side surface of the cable basin 34. .

The small water channel 44 is formed by connecting a plurality of small side grooves 45 in the longitudinal direction, and the small side groove 45 is formed by a drain block having a drain channel with a substantially elliptical cross section inside. In the upper part of the drainage block, a water guide slit for guiding surface water to the internal drainage channel is formed.
According to the configuration example of the buttock section 4 shown in FIG. 5, the two drainage basins 32, 32 are connected by the small water channel 44 so as to be able to conduct water, and therefore the cross drainage pipe 42 is not connected. Even if the catchment basin 32 is filled with rainwater, the rainwater can be guided to the catchment basin 32 on the right side of FIG.

  Further, according to the configuration example of the buttock section 4 shown in FIG. 5, even when the detour channel 57 as shown in FIG. 8 described later cannot be installed due to interference with an existing buried object, for example, By installing the small water channel 44 having a smaller cross section than the bypass water channel 57 in the vicinity of the cable rod 34, the flowing water from the center of the road toward the cable rod 34 is taken into the small water channel 44 over the entire length of the rod and the water collecting channel 32. There is also an advantage that can be led to.

FIG. 6 is a plan view of another configuration example of the buttock section 4 using the change block 31 and the catchment basin 32. This configuration example shows a case where the cable ridge 34 is not installed.
As shown in the figure, in the configuration example of the buttock section 4, only the change block 31 is connected to the side groove block 1 at the end of the side groove section 3, and the change block 31 is offset in the center of the road. A water tank 32 is arranged.
Accordingly, also in the case of FIG. 6, the water collecting basin 32 does not interfere with the storage space 18 of the side groove block 1, and therefore it is necessary to bypass the cables 5 to the outside of the side groove block 1 in the section where the water collecting basin 32 is installed. Therefore, the effect that the laying work of the cables 5 can be easily performed is obtained.

  In the configuration example of FIG. 6, in order to guide the drainage flowing down from the left and right side groove sections 3, 3 toward the change block 31, respectively, the upper space 37 of the change block 31 has each side groove section 3, 3. 3 and the direction change member 33 is not provided in the upper space 37.

[Components of the buttocks section (Part 2)]
FIG. 7A to FIG. 7D show a change block 31 and a detour waterway block 51 which are constituent members of the buttock section 4 (see FIG. 1).
7A is a plan view of the change block 31 and the detour channel block 51, FIG. 7B is a perspective view of the direction change member 33, and FIG. 7C is the change block 31 and a detour channel. FIG. 7 (d) is a side view of the change block 31.

Since the structure and function of the change block 31 and the direction change member 33 in FIG. 7 are the same as those in FIG. 3, the same reference numerals as those in FIG.
As shown in FIG. 7, the detour waterway block 51 includes a water guide block 52 that causes the wastewater that has flowed in from the drain port 39 of the change block 31 to flow down to the center of the road (left side of FIG. 7A), and the water guide block 52. The corner block 53 is configured to change the direction of drainage flowing in from 90 degrees again to return to the original direction (the drainage direction before flowing into the change block 31).

Among these, the water conveyance block 52 is shorter than the change block 31 and is smaller than the change block 31, for example, approximately half the cross-sectional height. Become.
The inflow end of the water guide block 52 is connected to the side wall portion of the change block 31 so that the inflow side opening thereof matches the drain port 39 of the change block 31. Further, the outflow end of the water guide block 52 is connected to the side wall portion of the corner block 53 so that the outflow side opening thereof matches an inlet 54 described later of the corner block 53.

On the other hand, the corner block 53 has the same length as that of the change block 31 and is smaller than the change block 31. For example, the corner block 53 is a substantially U-shaped concrete block having an open top. Consists of the body.
The corner block 53 has an inner air cross section that is substantially the same as the upper space 37 of the change block 31, and the side wall of the corner block 53 receives the wastewater that flows from the change block 31 through the water guide block 52. An inlet 54 is formed.

A direction changing member 33 is housed inside the corner block 53. The direction changing member 33 is formed in the corner block 53 in a state where the concave curved surface is desired for both the inlet 54 and the outlet so that the drainage is changed by 90 degrees in the opposite direction to the case of the changing block 31. Is housed inside.
For this reason, as shown by a thick arrow in FIG. 7, when the drainage flows from the entrance of the upper space 37 of the change block 31, it hits the concave curved surface of the direction changing member 33 in the upper space 37 and is 90 degrees toward the center of the road. The direction is changed and flows into the water guide block 52 from the drain port 39.

Thereafter, the waste water that has flowed into the water guide block 52 flows into the corner block 53 from the inflow port 54, strikes the concave curved surface of the direction changing member 33 in the corner block 53, and changes its direction to the original direction by 90 degrees. It flows out from the exit of the corner block 53.
Accordingly, when the change block 31 is connected to the end of the side groove block 1 and the water channel block 51 is connected to the change block 31, the drainage flowing through the upper space 37 is twice as shown by the thick arrows in FIG. After the direction change of 90 degrees, the flow down position is shifted to the center of the road (left side of FIG. 7A) by the length of the water guide block 52.

  7A illustrates the case where the flow of the drainage indicated by the thick arrow is in the order of the change block 31 → the water guide block 52 → the corner block 53, but when the drainage flows from the corner block 53, FIG. The drainage flows in the order of the corner block 53 → the water guide block 52 → the change block 31.

[Configuration example of the buttocks section (2)]
FIG. 8 is a plan view showing a configuration example of the buttock section 4 using the change block 31 and the detour channel block 51.
As shown in the figure, in the configuration example of the flange section 4, the change blocks 31 and 31 are connected to the side groove block 1 at the end of the two side groove sections 3 and 3 separated by the cable flange 34, respectively. Further, water channel blocks 51, 51 are connected to the respective change blocks 31, 31.

Further, the corner blocks 53, 53 of the water channel blocks 51, 51 are connected by a straight water channel 56 including a plurality of side groove members 55 installed continuously in the longitudinal direction.
Therefore, in the configuration example of FIG. 8, both longitudinal direction ends of the cable rod 34 from the respective water channel blocks 51, 51 disposed on both sides in the longitudinal direction of the cable rod 34 and the straight water channels 56 connecting the water channel blocks 51, 51 to each other. A bypass water channel 57 that is a drainage channel that communicates with the upper space 37 of each of the change blocks 31 and 31 connected to each other and that bypasses the periphery of the cable rod 34 is configured.

  As shown in FIG. 8, in the case of this ridge section 4, the water collection basin 32 is provided in the middle of the straight water channel 56, and this water collection basin 32 is located at the center of the road of the cable ridge 34. It is arranged to be close.

FIGS. 9A and 9B are plan views of another configuration example of the buttock section 4 using the change block 31 and the detour channel block 51.
9A shows a case where the width of the cable rod 34 is relatively large, and FIG. 9B shows a case where the width of the cable rod 34 is relatively small. That is, in the configuration example of FIG. 9A, the width dimension of the cable rod 34 (dimension in the road crossing direction) is smaller than the cable rod 34 of FIG. 8 but larger than the width of the side groove block 1.

As is clear from a comparison between FIG. 9A and FIG. 8, the change in the width dimension of the cable rod 34 installed at the site can be dealt with by adjusting the length of the water guide block 52. it can.
On the other hand, in the configuration example of FIG. 9B, the width dimension of the cable rod 34 (the dimension in the transverse direction of the road 2) is the same dimension as the width of the side groove block 1. For this reason, the water channel block 51 does not include the water guide block 52, and the corner block 53 is directly connected to the change block 31.

As described above, the water guide block 52 which is a constituent member of the water channel block 51 is suitable for the cable rod 34 having various width dimensions by appropriately adjusting the length or omitting the water guide block 52. A bypass water channel 57 can be formed.
Further, as is clear from comparison between FIG. 8 and FIG. 9, the length of the straight water channel 56 of the bypass channel 57 is changed to the length of the cable rod 34 (the dimension in the longitudinal direction of the road 2). It can cope by adjusting together.

  As described above, according to the drainage facility of the present embodiment, the bypass water channel 57 is a drainage channel that bypasses along the periphery of the cable rod 34, and therefore, the water guide block 52 and the straight water channel 56 constituting the bypass water channel 57. By appropriately adjusting the length of the cable, there is an advantage that even if the type and the number of installation of the cable rods 34 are variously changed depending on the site, the change can be flexibly handled.

[Comparative example of the buttocks section]
FIG. 10 is a plan view showing a comparative example of the buttocks section 4.
As described above, in this embodiment, the side groove block 1 constituting the electric wire common groove has the drainage channel 17 in the upper cross section and the storage space 18 for the cables 5 in the lower cross section. When connecting the drainage basin 32 and the cable basin 34 to the lateral groove section 3 constituted by the lateral groove block 1, for example, as shown in FIG. 10, the drainage basin 32 is arranged on the extension of the lateral groove section 3 as usual, It is also conceivable that the cable rod 34 is offset and arranged on the road center side (the lower side in FIG. 10) of the gutter section 3.

However, since the side groove block 1 of the present embodiment has the storage space 18 for the cables 5 on the bottom side in the block main body 11, the drainage trough 32 having a depth greater than that of the side groove block 1 is placed on the extension of the side groove section 3. If it arrange | positions, the storage space 18 will be parted by the water collecting basin 32.
Therefore, as shown in FIG. 10, in the installation section of the catchment basin 32, the cables 5 need to be laid around the outside of the side groove block 1, and in this case, the side wall portion 14 of the side groove block 1 is perforated. This necessitates laying the cables 5 very complicated.

In addition, if the water collecting basin 32 shallow enough not to interfere with the storage space 18 is employed, the above-mentioned problem does not occur, but with this, there is a high possibility that a desired water collecting capacity cannot be obtained.
Further, if the cable rod 34 is arranged offset to the center of the road, the storage space 18 of the gutter block 1 is not communicated with the internal space of the cable rod 34. In this case as well, as shown in FIG. It is necessary to make a detour outside the gutter block 1, and the installation work of the cables 5 becomes very complicated.

On the other hand, in the drainage facility of the present embodiment, the change block 31 having the upper space 37 that changes the drainage direction to the center of the road and the lower space 38 through which the cables 5 can pass straight is provided in the side groove section 3. The catchment 32 connected to the extension and communicating with the upper space 37 of the change block 31 is arranged offset to the center of the road in the gutter section 3, so the catchment 32 having a sufficiently large catchment capacity. Even if is adopted, the storage space 18 of the side groove block 1 is not divided.
For this reason, it is not necessary to make the cables 5 detour outside the gutter block 1 in the installation section of the water collecting basin 32, and the installation work of the cables 5 becomes easy.

Further, in the drainage facility of the present embodiment, the change block 31 having the upper space 37 for changing the drainage direction to the center of the road and the lower space 38 through which the cables 5 can pass straight is provided on the extension of the gutter section 3. Since the cable rod 34 connected and communicating with the lower space 38 of the change block 31 is disposed on the extension of the side groove section 3, the cables 5 in the side groove block 1 are not bent through the lower space 38. Can extend to 桝 34.
For this reason, it is not necessary to bypass the cables 5 to the outside of the gutter block 1 in the installation section of the cable rod 34, and the installation work of the cables 5 becomes easy.

Further, if the cable rod 34 communicating with the lower space 38 of the change block 31 is arranged on the extension of the side groove section 3, the cable rod 34 can be arranged close to the public-private boundary line B.
For this reason, the cable laying distance from the cable rod 34 to the private side can be shortened as compared with the case where the cable rod 34 is arranged offset to the center of the road (in the case of FIG. 10), and the cable center of the cable rod 34 is Since there are few overhang | projections to the side, there exists an advantage that the effective pavement width | variety of the road 2 can be ensured as much as possible.
