Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention allows drainage of rainwater or the like that has fallen on a road or the like to flow in through a drain port provided on the upper surface side.
The present invention relates to a gutter block that flows into the water passage space.

[0002]

2. Description of the Related Art Conventionally, a gutter block of this type includes, for example, a U-shaped gutter block for an open conduit, and the U-shaped gutter block has a removable lid. . Therefore, unless mud, sand, dust, dust, etc. that flowed into the U-shaped gutter block along with rainwater are removed, the flow rate of the gutter in the design calculation cannot be secured, and water will overflow onto the road, etc. It was necessary to remove and clean the lid, and then replace the lid again, which was a difficult task.

Further, in recent years, a cylindrical gutter block for an underdrain has also been used. However, since this gutter block has no lid, there is an advantage that noise due to rattling does not occur. And, in the case of this tubular gutter block for underdrain, the storage block having a storage part that intensively collects mud, sand, dust, dust, etc. flowing in with rainwater etc. from the drainage port of the tubular gutter block A grating or the like, which is installed adjacent to the gutter block and is detachably provided on the upper surface of the storage block, is removed to clean mud, sand, dust, dust, etc. accumulated in the storage portion.

However, mud, sand,
Dust, dust, etc. accumulate, so high-pressure water is poured into the tubular gutter block from one storage block, and mud, sand, dust, dust, etc. in the tubular groove block are pushed out to the other storage block together with the high-pressure water. A method of sucking and cleaning mud, sand, dust, dust, etc. accumulated in the storage part of the other storage block by a vacuum device is adopted. This cleaning method is efficient because there are few places to be cleaned, but it requires a device and work for pouring a large amount of high-pressure water, which is very expensive.

The present invention has been made in order to solve the above-mentioned drawbacks of the prior art. The object of the present invention is to reduce the number of times of cleaning because dusts and the like are less likely to accumulate and the cost required for cleaning work. The purpose is to provide a block for a gutter that is cheap.

[0006]

In order to achieve the above object, the gutter block according to the present invention has the following structure. That is, a gutter block having a drainage port on the upper surface side and a water passage space for flowing the wastewater flowing in through the drainage port, wherein the drainage flows directly into the water passage space through the drainage port. In order to divide into a primary side water passage space and a secondary side water passage space where wastewater does not directly enter through the drainage port, a weir portion is erected vertically in the water passage space. In addition, a communication portion is formed that connects both water passage spaces for flowing wastewater from the primary water passage space to the secondary water passage space.

Further, it is preferable that the dam portion is provided so that the running water cross sectional area of the primary side water passing space is smaller than the running water cross sectional area of the secondary side running water space.

Further, it is desirable that the communicating portion is formed above the water passage space.

Further, it is desirable that the cross-sectional shapes of the primary side water passage space and the secondary side water passage space become narrower from the upper side to the lower side.

[0010]

[Function] Since the running water cross-sectional area of the primary water-flowing space is smaller than the running water cross-sectional area of the entire water-flowing space, even if the amount of drainage flowing directly through the drainage port is small, the water level of the primary-side water flow space is small. Is relatively high and the drainage flow becomes faster. Further, when the amount of drainage flowing through the primary side water passage space is large, the drainage flows from the primary side water passage space to the secondary side water passage space through the communication portion. At that time, in the secondary water passage, mud, dust, etc. do not flow directly into the secondary water passage, so the wastewater flowing through the secondary water passage is more dirty than the drainage flowing through the primary water passage space. Less is.

The running water cross-sectional area of the primary side water passage space is 2
Since the weir is provided so as to be smaller than the running water cross-sectional area of the secondary water passage, the water level in the primary water space is high even if the amount of drainage is small, and the drainage flow becomes faster.

Further, since the communication portion is formed on the upper side of the water passage space, the wastewater flowing through the secondary water passage space is less polluted than the wastewater flowing through the primary water passage space. Becomes

Further, since the cross-sectional shapes of the primary side water passage space and the secondary side water passage space are narrowed from the upper side to the lower side, both of the water passage spaces have a small amount of drainage. The water level is high and the drainage flow is faster.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a gutter block according to the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, this gutter block is an underdrain type gutter block 3 having a cross-sectional shape that narrows from the upper side to the lower side, and is provided along a roadway (not shown). Arranged. Then, between the plurality of gutter blocks 3, as shown in FIG. 1, mud, sand, dust,
A storage block 4 including a storage portion 4a that collects dust and the like in a concentrated manner is arranged, and a space in the storage block 4 and a water passage space 12 (described later) in the gutter block 3 are connected to each other.

A curb portion 6 for stopping the flow of water is integrally formed along the longitudinal direction on the side of the upper surface 5 of the gutter block 3 (on the left side in FIG. 2),
In addition, a part of the upper surface 5 makes water flow easily,
The slope is a downward slope from the roadside toward the curb 6. In the vicinity of the curb portion 6 on the upper surface 5 of the gutter block 3, a large number of drainage ports H are arranged at regular intervals in the longitudinal direction, and rainwater or the like is passed through the drainage ports H into the water passage space 12. Flows in.

At this time, since mud and the like flow into the water flow space 12 together with the rainwater, the water flow in the gutter block 3 is allowed to flow without being blocked by the mud and the like. Therefore, when the gutter block 3 continues for a length of, for example, about 10 to 20 meters, the storage block 4 is arranged at the end thereof, and the mud and the like flowing into the gutter block 3 is flowed to the storage part 4a and stored there. So that Then, the bottom surface portion T in the water passage space 12 of the gutter block 3 is arranged so that the mud and the like flowing into the gutter block 3 flows to the storage block 4 together with water.
Needs to be inclined so as to have a downward slope in the direction of the storage block 4.

The gutter block 3 and the storage block 4 are installed on cast-in-place concrete 8 which is laid in a groove (not shown) deeply dug along a side portion of the road. In this case, the bottom of the storage section 4a is located lower than the bottom of the gutter block 3 so that the mud and the like flowing into the gutter block 3 flows into the storage section 4a of the storage block 4 together with water. It is installed.

Further, a rectangular opening 9 is provided on the upper surface of the storage block 4 to remove the dust and the like accumulated in the storage portion 4a, and a grating 10 or the like can be removed from the opening 9. It is located in. Therefore, an operator or the like can remove the dust or the like accumulated in the storage portion 4a by removing the grating 10 or the like and sucking it up with a vacuum device or the like. Further, a curb portion 11 is provided on one side of the upper surface of the storage block 4 so as to be continuously provided with the curb portion 6.
The upper surface 4b of the storage block 4 is also formed with an inclined surface having a downward slope toward the curb 11, similar to the upper surface 5 of the gutter block 3.

In the gutter block 3, there is formed a water passage space 12 for flowing rainwater or the like flowing in through the drainage port H to the storage block 4. In the water passage space 12,
A weir portion 13 extending in the vertical direction is provided so as to extend toward the storage block 4. The weir portion 13 includes a primary side water passage space 14 through which rainwater and the like directly flow into the water passage space 12 and a secondary side water passage through which rainwater and the like do not directly enter through the drainage port H. It is divided into space 15. Further, a communication portion 16 is formed on the upper side of the weir portion 13 for flowing drainage and the like overflowing from the primary water passage space 14 to the secondary water passage space 15. However, in normal times, the rainwater or the like flowing in through the drainage port H flows only in the primary side water passage space 14, and only when a large amount of rainwater or the like flows in through the drainage port H, the primary side water passage space Since it is preferable that the waste water overflows into the secondary side water passage space 15 from 14, the communication portion 16 is formed in the water passage space 1.
It is desirable to be formed on the upper side of 2 as much as possible.
However, the communication part 16 is not necessarily limited to this, and for example, a part of the dam part 13 may be perforated to be formed.

Further, the size of the communication portion 16 is set so that when a large amount of rainwater or the like flows in through the drainage port H, the drainage port H is prevented from flowing back to the road or the like through the drainage port H. The amount of drainage of the drainage flowing from the primary side water passage space 14 to the secondary side water passage space 15 is made larger than the amount of inflowing rainwater or the like through the drainage port H also in this case. It is desirable that the weir portion 13 is formed up to a position above the water passage space 12 so that drainage of the inflowing rainwater or the like flows only in the primary water passage space 14 as much as possible.

However, as described above, the primary side water passage space 14 is a water passage space into which rainwater or the like directly flows in through the drainage port H, and the secondary side water passage space 15 is defined by the drainage port H. Although it is a water passage space where rainwater etc. does not enter directly, this means that the water passage space 12 is simply divided into two, such as a primary side water passage and a secondary side water passage. Not of. Therefore, the primary water passage space 14 or the secondary water passage space 15
For example, it may be divided into two or more water passages.

In the case of this embodiment, in order to keep the water level of the wastewater in the primary side water-flowing space 14 high, the flowing water cross-sectional area of the primary-side water flow-through space 14 is made equal to that of the secondary-side water-flowing space 15. The cross-sectional shapes of the weir portion 13, the primary side water passage space 14 and the secondary side water passage space 15 are determined so as to be smaller than the above. However, the total cross-sectional area of the water flow space 12 is determined by the surrounding environment in which the gutter block 3 is installed, for example, the road width of the road or the rainfall amount. Each running water cross-sectional area of the secondary side water flow space 15 is also determined by performing a design calculation based on the surrounding environment.

The cross-sectional shape of the primary side water passage space 14 is
For example, as clearly shown in FIG. 2, it has a vertically long shape that narrows from the upper side to the lower side, and the secondary side water passage space 1
The cross-sectional shape of 5 is, for example, a part of an egg shape that narrows from the upper side to the lower side. As a result, even if the amount of drainage of rainwater or the like flowing in through the drainage port H decreases in the primary-side water passage space 14, as compared with the case where the cross-sectional shape is a concave shape having substantially parallel side surfaces, Since the water level can be maintained at a high level, the drainage, dust, etc. will be stored in the storage unit 4.
It becomes easy to flow toward a. Further, even when the amount of drainage is reduced, the water level of the secondary side water passage 14 can be maintained at a higher water level as compared with the case where the secondary side water flow space 14 has a concave shape having side surfaces that are substantially parallel to each other, and structurally. Also excellent in strength. Therefore, in both the primary side and secondary side water flow spaces 12, 14, the flow of drainage becomes faster and becomes easier to flow, and mud,
Sand, dust, dust, etc. flow toward the reservoir 4a together with the drainage. Therefore, the dust and the like accumulated in the storage portion 4a needs to be removed by removing the grating 10 and the like from the opening 9, but the primary side water passage space 14 and the secondary side water passage space 15 of the gutter block 3 are removed. As there is almost no dust, it does not need to be cleaned. However, if necessary, a cleaning method is used in which high-pressure water is poured from one storage block 4 into the water passage space 12 of the gutter block 3 and dust and the like are pushed out to the storage portion 4a of the other storage block 4 together with the high-pressure water. Good.

Next, another embodiment will be described with reference to FIG.

The gutter block of this embodiment is provided with a curb portion 21 on the upper surface side as in the above embodiment,
This is an underdrain type gutter block 20 having a large number of outlets 22 arranged in a row at regular intervals in the vicinity of the curb portion 21, and a water passage space 23 is provided therein. Since the bottom side of the gutter block 20 is open, it has a structure in which the concrete member 24 having the shape described below is fitted. That is, this concrete member 2
Reference numeral 4 includes a bottom plate portion 25 having a width corresponding to the bottom portion of the gutter block 20, and a weir portion 26 integrally formed so as to extend upward from the bottom plate portion 25.
Therefore, the cast-in-place concrete K laid in a groove dug deep along the side of the road is fixed in a state where the concrete member 24 is standing while covering the peripheral surface of the bottom plate portion 25 and the lower side surface of the dam portion 26. After that, the gutter block 20 is covered on the concrete member 24 so that the dam portion 26 fits into the water passage space 23 of the gutter block 20.

This weir portion 26 is similar to the above-described embodiment, in the water passage space 23, the primary side water passage space 27 into which rainwater or the like directly flows through the drainage port 22, and the rainwater through the drainage port 22. Etc. are separated from the secondary side water passage space 28, and drainage overflowing from the primary side water passage space 22 flows into the secondary side water passage space 28 on the upper side of the weir 26. A communication portion 29 for forming the is formed. In addition, in order to keep the water level of the wastewater in the primary water passage space 27 as high as possible, the flowing water cross-sectional area of the primary water passage space 27 is smaller than the flowing water cross-sectional area of the secondary water passage space 28. In addition, the weir portion 25 is arranged at a position closer to the primary water passage space 27 side than the center of the water passage space 23.

Next, another embodiment will be described with reference to FIG.

The gutter block of this embodiment is an open-ditch type gutter block 30 having a water passage space 31 therein. The gutter block 30 is open on the upper side, and a concave step portion 32 is formed on the upper side so as to extend in the longitudinal direction, and a lid 33 is formed in the concave step portion 32.
Is to be placed. In addition, at the center of the side of these lids 33, there is an outlet 34 that can also be used as a handle.
Are formed.

The lower part of the gutter block 30 is open, and the concrete member 3 having the shape described below is formed.
It has a structure in which 5 is fitted. That is, the concrete member 35 is composed of a bottom plate portion L having a width corresponding to the bottom portion of the gutter block 30, and a dam portion 36 integrally formed so as to extend upward from the bottom plate portion L. . Therefore, the cast-in-place concrete M laid in a groove dug deep along the side of the road and the like is fixed in a state where the concrete member 35 is standing while covering the peripheral surface of the bottom plate L and the lower side surface of the dam 36. After this, the gutter block 30 is put on the concrete member 35 so that the dam portion 36 fits into the water passage space 31 of the gutter block 30.

This weir portion 36, like the first and second embodiments, has a primary side water passage space 37 into which water such as rainwater directly flows in through the water passage space 31 and drainage water, and drainage water. It is divided into a secondary side water passage space 38 through which rainwater and the like do not directly enter through the mouth 34. In the case of this embodiment, the drain port 34 is the lid 3
Since it is arranged at the center of the water supply port 3, rainwater or the like entering through the drainage port 34 is provided on the upper side of the weir portion 36.
An inclined portion 39 extending from the primary water passage space 37 upward toward the secondary water passage space 38 is formed so as to be guided to 7. Therefore, rainwater or the like entering through the drainage port 34 travels along the upper surface of the inclined portion 39 and flows into the primary side water passage space 37.

A large number of communicating portions 40 are formed on the upper side of the weir portion 36 in the vertical direction so as to be lined up at regular intervals in the longitudinal direction, so that the primary side water passage space is formed. When the amount of drainage increases, the drainage flows from the primary water passage space to the secondary water passage space. In addition, in order to keep the water level of the wastewater in the primary water passage space 37 as high as possible, the flowing water cross-sectional area of the primary water passage space 37 is smaller than the flowing water cross-sectional area of the secondary water passage space 38. In addition, the weir portion 36 is arranged at a position closer to the primary water passage space 37 side than the center of the water passage space 31.

Of course, the gap between the lid 33 and the lid 33,
Alternatively, drainage of rainwater or the like may directly enter the secondary side water passage space through a gap between the lid 33 and the gutter block 30 or the like. Since it is usually less than drainage such as rainwater entering from the inside, there is no particular problem. Therefore, these gaps do not correspond to the drainage port in the present invention, but of course, the presence of these gaps and the like does not prevent inclusion within the scope of the gist of the present invention.

The present invention is not limited to the above-mentioned embodiments, but various modifications can be made. For example, the shapes of the communication portion, the primary side water passage space, the secondary side water passage space, and the weir portion are not limited to those in the above embodiment, and may have any other shape. Further, the position of the communication part does not necessarily have to be above the weir part.

Furthermore, it is not necessary to provide the weir so that the cross sectional area of the secondary water passage space is larger than the cross sectional area of the primary water passage space. In addition, the cross-sectional shapes of the primary side water passage space and the secondary side water passage space do not necessarily have to be narrower from the upper side to the lower side, and the communication portion is also on the upper side of the water passage space. It need not be formed.

[0036]

As is clear from the above description, the gutter block according to the present invention has the following effects.

According to the gutter block according to the first aspect of the invention, the weir portion provided upright in the vertical direction in the water-passing space allows the drainage to directly flow into the water-passing space through the drainage port. Since the side water passage space and the secondary side water passage space through which the drainage does not directly enter through the drain port are divided, the water level of the primary side water passage space can be kept relatively high even if the amount of drainage is small. As a result, in the primary side water flow space, the flow of drainage becomes faster and easier to flow, and mud, sand, dust, dust, etc. flowing in through the drainage port also flows along with the drainage. Therefore, the frequency of cleaning the gutter block can be reduced, and the use of high-pressure water for cleaning is almost unnecessary, so that the cost required for the cleaning operation can be reduced. In addition, since a communication part for flowing the drainage from the primary water passage space to the secondary water passage space is formed between the primary water passage space and the secondary water passage space, 1 When the amount of drainage in the secondary water passage space increases, the drainage flows from the primary water passage space to the secondary water passage space, and the amount of water in the entire water passage space of the gutter block is also secured. At that time, mud,
Since dust and the like does not flow directly into the drainage port, the drainage flowing through the secondary water passage space is less dirty than the drainage flowing through the primary water passage space, and there is less dirt inside the secondary water passage space. There is not much adherence, and a planned amount of running water is secured.

According to the gutter block of the second aspect, the weir portion is configured so that the running water cross-sectional area of the primary-side water passing space is smaller than the running water cross-sectional area of the secondary-side running water space. The water level can be kept high in the primary water passage space even if the amount of drainage is small. Thereby, in the primary side water flow space, the flow of drainage becomes faster and easier to flow,
The dust or the like flowing through the drainage port flows along with the drainage, and the frequency of cleaning the gutter block can be further reduced.

Further, according to the gutter block according to the third aspect, since the communication portion is formed above the water passage space, the waste water flowing through the secondary water passage space is discharged through the primary water passage space. There is little dirt in the drainage flowing in the water space,
The accumulation of mud, sand, dust, etc. is reduced, and the frequency of cleaning the secondary side water passage space can be further reduced.

Further, according to the gutter block of the fourth aspect, the cross-sectional shape of the primary side water passage space and the secondary side water passage space is narrowed from the upper side to the lower side. The primary and secondary water passages can maintain a high water level even if the amount of drainage is small. As a result, in both the primary-side and secondary-side water flow spaces, the flow of drainage becomes faster and easier to flow, and the mud, sand, dust,
Dust also flows along with the drainage, and the gutter block need not be cleaned at all.
