Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collecting / draining block installed on a drainage road surface and a block piece forming the collecting / draining block.

[0001]

2. Description of the Related Art In recent years, a drainage road surface is widely used as a surface treatment method for roads, which is constructed by using asphalt having a void while a resin coating of crushed glass or crushed stone. The road surface laid by such drainage road surface,
A large amount of underground water flowing in the paved road will be generated.
As a means for draining this underground water, as shown in FIG. 10, a gutter block has been proposed in which a water guiding member having a water guiding hole is attached to a side wall and the underground water is guided into the gutter through this water guiding member. .

However, the water guiding member of this gutter block is exposed to running water every time it rains. Therefore, even if anticorrosive treatment such as rustproofing is applied, it may be corroded by long-term use. Also,
In some cases, the water guiding holes of the water guiding member were clogged, leading to a decline in the water collection and drainage function.

Further, when a vehicle frequently passes over the upper surface of the gutter block, a gap is gradually formed between the water guiding member and the block, which may cause rattling. Then, the block once rattled accelerates the expansion of the gap generated between the water guiding member and the block when the vehicle further passes through. When a vehicle passes over this rattling block, it also causes noise.

Further, in the gutter block installed on the asphalt, the asphalt portion has a higher wear speed than the concrete portion, and gradually a step as shown in FIG. 11 is generated. When the vehicle travels in such a state, the concrete portion of the gutter block is gradually worn. Then, only the water-conducting member having the highest durability wears slowly, and a large step is generated between the water-conducting member and the asphalt or block. When a vehicle travels on a road surface having such a step, there is a problem that the tire is flat due to the corner of the water guiding member.

However, since the water guiding member is integrally manufactured and fixed in the block, it is impossible to replace only the water guiding member. Further, it is not possible to repair only the wear of the concrete part that has once worn. So, after all, the entire gutter block was replaced.

[0006]

Therefore, the present invention has been made in view of the above problems and is capable of draining underground water flowing in a drainage road surface and degrading the drainage function. An object of the present invention is to provide a block for collecting and draining and a block piece forming the block for collecting and draining, in which the blocks can be easily replaced.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a collecting / draining block used for a drainage road surface or a block piece forming an upper part of the collecting / draining block, and a side surface of the collecting / draining block for collecting rainwater flowing underground. It has the function of collecting and draining water from. Here, the drainage road surface includes all road surfaces of a type in which rain falling on the surface of the road penetrates into the road surface. For example, as shown in FIG. 9, a permeable pavement in which rainwater penetrates deep into the ground, a permeable pavement in which a permeable layer is formed on the upper layer of a non-permeable base layer, and rainwater flows over the base layer, up to a certain amount of water. This includes all paved roads where rainwater may flow to the sides of the water collection / drainage block, such as water-retentive pavement that retains water and drains excess rainwater, and other road surfaces covered with blocks that have permeability.

In order to ensure the drainage and drainage function of the water collection and drainage block of the present invention, a water conduit comprising a communication port or a notch that communicates with the water collection portion inside the water collection and drainage block from above the side surface of the water collection and drainage block. Has been formed. Further, in order to prevent a large opening from being formed on the side surface by the water guide passage, a plurality of holes or water guide holes having a lattice shape are formed. This is because if there is a large opening on the side surface, the asphalt may enter through this opening when laying the asphalt road surface, which is prevented. As a method of forming the water guide hole, a hard plate-like body formed in a hole or a lattice may be attached after making the concrete block, or a metallic member having the water guide passage and the water guide hole is made as a block. Sometimes it may be integrally molded. The sizes of the water conduit and the water hole may be appropriately selected and used. Further, the water conduit and the water hole can be communicated with the upper surface of the water collection and drainage block.
As a result, surface water flowing on the road surface can be collected and discharged. At this time, the water conduits and water holes formed on the side surface and the water conduits and water holes formed on the upper surface may be integrally formed, or may be formed at completely different places. I do not care.

Further, in the block for collecting and draining water of the present invention, in order to replace the block portion having the upper water conduit and the water conduit hole, it is introduced with the upper block piece having the water conduit and the water hole. It is made by stacking separately molded lower block pieces that collect rainwater. Even if the headrace or the water guide hole is deteriorated by forming in this way, only the block part of the upper part where the water guideway and the water guide hole are formed without replacing the entire block buried deep in the ground. If replaced, the initial drainage function can be secured. Therefore, the upper block piece is 25
It is preferable that the thickness is 20 cm or less, and further 20
It is desirable to be formed to be cm or less. More preferably, the upper block piece is preferably formed to be slightly thicker than the thickness of the drainage road surface. For example, if the drainage road surface has a thickness of about 5 cm, the upper block piece is preferably made to have a thickness of about 6 cm to 10 cm. The upper block piece may be a block piece forming the uppermost surface of the water collecting basin, an L-shaped block, or the like, but is not limited to these. Also,
As the lower block piece, generally, a gutter block, a lower part of the water collecting basin, an underdrain block and the like can be considered. The lower block piece does not necessarily have to be integrated, and the lower block piece itself may be formed by stacking more layers.
