DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a gutter block capable of purifying wastewater and adjusting drainage.

[0002]

2. Description of the Related Art Gutter blocks are used for draining rainwater, domestic wastewater, etc. into sewers or rivers.
2. Description of the Related Art Conventionally, as a side groove block, a block body having a U-shaped cross section with an upper lid has a generally known structure. Rainwater or domestic wastewater that has flowed into such a gutter block is carried to a sewage treatment plant or the like for purification, but may be directly discharged to a river as in the past. As described above, when the water is directly discharged into the river, it is not purified at all, and thus has a great influence on the pollution of the river. In addition, since mud and the like also flow into the gutter block, if the amount of drainage is large, these mud and the like are also drained together into the river, causing the river to become dirty and generate odor.

[0003] For this reason, the applicant of the present application has filed Japanese Utility Model Application No. 63-756.
No. 06 (Utility Model Registration No. 1924862)
A gutter block capable of purifying wastewater and adjusting drainage was proposed. This gutter block divides the drain passage 13 into upper and lower parts by a permeable wall 12 as shown in FIG.
The bottom drainage passage 14 is provided with a water-permeable partition wall, the bottom drainage passage is provided with a number of compartments, and the room is filled with a purification material 17. Things.

As a result, rainwater or domestic wastewater which has flowed into the gutter block once penetrates the drainage passage on the bottom side into the formation room, and is purified by the purification material 17 filled in the room. It has become. In addition, the partition wall of the room formed in the drain passage on the bottom side prevents the inflow of mud and the like into the river due to an increase in the amount of drainage, and further prevents abrupt drainage.

[0005]

However, depending on the situation, sediment deposited in the drainage passage may interfere with purification and drainage. For example, when the water-permeable wall dividing the drainage channel into upper and lower portions has a structure in which a large number of holes are provided, the sediment deposited on the wall may block the holes and hinder water permeability. Further, sediment may be deposited on the purification treatment material, thereby impeding purification by preventing the permeation of wastewater or the like into the purification treatment material. As a result, the original purification processing or the like is not performed.

The present invention has been made in view of the above circumstances, and removes sediments to maintain good drainage and purify wastewater so as not to hinder purification and drainage of gutter blocks. It is an object of the present invention to provide a gutter block that can perform satisfactorily.

[0007]

According to the present invention, a drain passage is vertically divided by a water-permeable wall, and a water-permeable partition is provided in a bottom drain passage so that a large number of fractions are formed in the bottom drain passage. The following means are adopted in a gutter block which is provided with a purified room and is filled with a purification material.

First, according to the first aspect of the present invention, when a purifier having a large number of water wheel-shaped rotating bodies is provided on a water-permeable wall and / or on the purification treatment material, the water is discharged. By rotating these rotating bodies in the water stream, the sediment was soaked in water, and the soared sediment was caused to flow along with the water stream. In a general gutter block, a small amount of wastewater or the like is usually drained with a gentle flow in normal times, and the accumulation of sediment tends to proceed. At this time, the rotating body does not generally rotate because of the gentle flow. However, when a large amount of drainage such as heavy rain is generated, both the amount of water and the flow of water increase, and the rotation of the rotating body is promoted, and the rotation causes the sediment to fly up. As a result, the soared sediment is washed away by a large amount of drainage, and the sediment in the drainage passage is removed.

However, until the sediment is removed by heavy rain as described above, the sediment remains on the permeable wall and / or on the purification material. It is. Therefore, the wastewater or the like hardly permeates into the purification material, and the purification is not sufficiently performed, and the sediment including waste and the wastewater are spoiled to emit a bad smell. Therefore, in the invention described in claim 2, claim 1
By using the rotating body according to the above as a carrier and adsorbing microorganisms capable of decomposing the waste in the drainage passage, the source of these spoilage or the spoilage product is decomposed, thereby promoting purification and reducing malodor. I tried to prevent it.

[0010] Further, the purifier adsorbing the microorganisms as described above is used as a purification material. In other words, in the invention according to claim 3, the purifying material includes a purifier in which microorganisms capable of decomposing debris in the drainage passage are adsorbed on a carrier, and the carrier can rotate in the water flow in the drainage passage. It was made to have a number of rotating bodies like a water wheel arranged in the water wheel. In this way, when wastewater flows slowly, it acts as a purification material due to the activity of microorganisms. On the other hand, when a large amount of wastewater such as heavy rain is generated, the rotation of the rotating body is promoted and sediments fly. It is raised and drained, removing the sediment in the bottom drainage passage.

BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) A first embodiment will now be described with reference to FIG.
The described invention will be described. 1 to 3 show an embodiment of a gutter block 10 provided with a purifier 1 to be described later on a water-permeable wall 12, as shown in FIG. It has a shaped block body 10a and a separate bottom wall 10b attached to the lower part, and the upper opening is covered with a grating 11.

The drainage passage 13 of the side gutter block 10 is divided into upper and lower stages by an intermediate wall 12. The wall 12 is water-permeable and may have a structure in which a large number of holes of about 5 to 10 mm are provided, or a wall obtained by joining a large-grain gravel with ready-mixed concrete or the like and solidifying it. May be used. Large garbage such as fallen leaves is retained in the upper drain passage 13 by the wall 12. The wall 12 may be formed separately from the gutter block 10 or may be integrally formed.

On this wall, there is provided a purifier 1 having a large number of water wheel-shaped rotators 4 arranged in a direction that can be rotated by the water flow in the drain passage 13. This purifier 1
Two horizontally long side plates are connected to each other by two connecting rods 3 at both ends, and when inserted into the side groove block as shown in FIGS. 1 and 3, the side plates 2 and 2 are on both sides of the drain passage 13. It is located in each. And about 4 to 5 rotating bodies 4
Are wrapped around two side plates 2 and 2 in a skewered manner, and a large number of such shaft bars 3 are arranged at appropriate intervals over the entire length of the side plates 2 and 2. It is provided in. Therefore, the purifier 1 has a shape just like an abacus.

It is to be noted that a plurality of rotating bodies 4 as described above may be provided vertically, and in this case, the shape is such that a plurality of abacus-shaped cleaners are stacked.

The rotating body 4 has a diameter 5 made of plastic.
5 cm, and the blade is shaped like a water wheel as shown in FIG. 5 is a suitable example. The blade has a concave curved surface like a blade (at the tip of an oar for rowing a boat or the like). As a result, it is easy to obtain rotational force because the water flow is easily affected. However, what is meant by the water wheel shape in this application is that the rotating body 4 moves by hydraulic power, and a part of the rotating body 4 produces a movement that can lift up sediments such as mud and sand mud and soar. It may be. For example, like a rotating body 4 shown in FIGS. 6 and 7, a rotating body that does not have a concave curved surface like a blade may be used. It is such a rotating body 4
Is placed in a water flow, the rotational moment of the rotating body 4 is balanced in the forward and reverse directions, and the rotating body 4 does not rotate. However, as shown in FIG. This is because a water flow is added to the water, resulting in a rotational force.
Further, such a rotating body can be individually rotated while penetrating through the shaft rod 5.

Such a purifier 1 is provided and used on the wall 12 of the side groove block 10 as shown in FIGS. In this way, even if deposits accumulate on the wall 12,
When the amount of water increases, one of the rotating bodies 4 rotates, and sediments near the rotating body 4 are washed away and removed. Like this
When the sediment was partially removed and only the hollow was depressed, the collapse spread as if the surrounding sediment avalanched into this depression, and along with this, the sediment was partially buried and stopped rotating The adjacent rotating body 4 begins to escape from the buried state,
As a result, the rotation is promoted, and the removal of the deposit is propagated.

Drainage passage 14 at the bottom of gutter block 10
Are provided with a large number of partitions 15 on the bottom wall 10b, whereby a large number of compartments 16 are formed in the drainage passage 14 on the bottom side. Partition walls 15 that separate each room 16
Has a water-permeable structure like the wall dividing the drain passage 13 of the side groove block 10 into upper and lower stages. The number of the partition walls 15 is about 3 to 4 per one side groove block 10 of about 2 m, but the number is not particularly limited. Further, the intervals between the partition walls 15 are not limited to the equal intervals, and may be formed at different intervals. Therefore, the partition 15 is formed separately from the bottom wall, and the partition 1 is formed on the bottom wall.
It is also possible to provide a groove in which the partition 5 is fitted so that the partition wall 15 can be formed at an arbitrary position.

The inside of the room 16 is filled with a purification material 17. Activated carbon, ion exchange resin, bacteria, crushed stone, sand, wood fiber, or the like can be used as the purification treatment material 17. Each room 16 may be filled with only one of these purification materials 17, or two or more types of purification materials 17 may be filled in each room 16. If the wall 12 in the middle of the drainage passage is formed separately, the purifying material 17 filled in the room 16 can be replaced later with a new one.

FIG. 9 shows another embodiment of the present invention. The side groove block 10 has a U-shaped cross section and an intermediate wall 12 formed therein. And
As shown in the figure, the purifier 1 is provided on a purification material 17. In this case, since the flow of wastewater or the like is blocked by the partition wall 15 in the drainage passage 14 on the bottom surface side, if a large number of holes are provided in the partition wall 15 to ensure water permeability, the drainage passage 14 should be made larger by increasing this hole. It is sufficient that a certain amount of water flow is generated. The purifier 1 may be, for example, a rotary body having a plurality of stages other than the illustrated one. Further, FIG.
This is another example of the invention according to claim 1, wherein the side groove block 10 uses a block body having a U-shaped cross section as in FIG. It is prepared for both above. In addition, although not shown, a gutter block having no bottom wall may be used, and in this case, rainwater or the like flowing into the gutter block can penetrate into the ground through the purification material.

Also, microorganisms can be adsorbed on the rotating body. This case corresponds to the second aspect of the present invention. If the rotating body is formed of porous plastic, ceramic, or the like, it is excellent in adsorbing microorganisms as a carrier. Further, only a part of the rotating body is immersed in water, for example, when the amount of waste water is small, so that if the other part of the rotating body exposed from the water surface dries, the adsorbed microorganisms are likely to be killed. Therefore, if even a part of the rotating body is immersed in water, it is more preferable to use a material such as a capillary tube so that moisture can be entirely sucked up. In addition, when a place where the microorganism is inhabited and drained relatively regularly is set as an installation target, the effect is remarkable.

In the side groove block according to the first aspect,
Microorganisms in the natural world can inhabit and inhabit the rotating body of the purifier. Therefore, if such a purpose is given to the gutter block of claim 1, the gutter block of claim 2 also becomes.

(Embodiment 2) A gutter block according to a third aspect of the present invention will be described below. This gutter block is mostly the same as that of the first embodiment. That is, as shown in FIG. 11, a block body 10a having an H-shaped cross section and a separate bottom wall 10b attached to the lower part are provided. Is Grating 1
1 for covering. Further, the drainage passage 13 of the side groove block 10 is divided into two upper and lower sections by an intermediate wall 12, and the wall 12 is permeable. Further, in the drainage passage 14 on the bottom side of the gutter block 10, a large number of water-permeable partition walls are provided on the bottom wall 10b as in the first embodiment. A defined room 16 is formed.

The difference is that a large hole of about several cm is provided in the partition wall to ensure water permeability. Therefore, when the amount of water is large, the partition wall is provided in the drainage passage 14 on the bottom side, but the partition wall is provided. The point is that a certain amount of water flow is generated without being obstructed.

Another difference is that a purifier 1 that is substantially the same as the purifier used in the first embodiment is used for the purification material 17 filled in the room 16. is there. As shown in FIG. 12, in this purifier 1, two laterally long side plates 2 corresponding to the length of the room 16 are connected to each other at four corners by four connecting rods 3, as in the first embodiment. A shaft bar 5 through which about 4 to 5 rotating bodies 4 are pierced in a skewered manner is hung over two side plates 2, 2, and such shaft bars 5,. A large number are provided side by side at appropriate intervals over the entire length. The difference from the first embodiment is that such a horizontal arrangement is provided in three steps vertically in the depth direction of the side groove block, and the shape is such that the abacus is overlapped in three steps.

In such a gutter block 10, wastewater and the like can be prevented from flowing into the river due to an increase in the amount of drainage by a partition wall, and furthermore, abrupt drainage can be prevented.
Purification of wastewater and the like that has permeated each room is performed by microorganisms in the rotating body.

On the other hand, if sludge or sediment accumulates excessively in the room, during heavy rain, the rotating body of the purifier rotates due to the flow of water in the drainage passage, and the sludge or sediment that accumulates due to this rotation. , And can be removed by being washed away with wastewater. In other words, self-adjustment can be performed while preventing sludge or the like from flowing into the river at once due to increased water or the like, while preventing the sludge or the like from collecting too much in the gutter block.

[0027]

As described above, according to the first aspect of the present invention, when a purifier is provided on a water-permeable wall, deposits deposited on the wall are removed and drainage occurs. It improves the water permeability of the wall, so that the effect of purification can be maintained. Further, when a purifier is provided on the purification treatment material, the deposits deposited on the purification treatment material are removed, so that the permeation of wastewater or the like into the purification treatment material can be sufficiently performed, and the purification can be maintained. In addition, drainage of the drain passage having the bottom side is improved. In addition, the above effect can be further obtained if the side groove block is provided with a purifier on the water-permeable wall and on the purification treatment material.

According to the second aspect of the present invention, the microorganisms are adsorbed by using the rotating body as a carrier, so that wastewater and the like are purified by decomposition, and an odor and the like can be prevented.

According to the third aspect of the present invention, purification of waste water and the like that has permeated each room is performed by microorganisms of the rotating body. Also, if sludge or sediment accumulates too much in the room, it becomes a stream of water in the drainage passage, and the rotating body of the purifier rotates due to the water current. It can be washed away and removed. In other words, while the sludge or the like is prevented from flowing into the river at once due to increased water or the like, the excessively accumulated sludge or the like is suppressed by the rotating body of the purifier, and the self-adjustment can be performed so that the sludge or the like is not excessively collected in the gutter block.
