Description

[Detailed description of the invention] [Purpose of the invention] Industrial application field The present invention relates to a water-permeable tile block that is installed on a sidewalk or outside ditch to allow rainwater to penetrate into the ground.

Conventional technology In the past, asphalt, concrete, or colored blocks were laid on sidewalks or outside ditches, but because rainwater does not penetrate into the ground easily, during the rainy and typhoon seasons, the water that does not penetrate into the ground causes flash floods. As the water flows into the manhole, the sewer pipe becomes full of water, and water that cannot flow into the sewer pipe or backflows from the manhole overflows onto the road surface, creating a risk of flash flooding or causing flooding under the floors of houses. It had drawbacks such as:

In addition, because rainwater does not penetrate into the ground, it is not possible to provide sufficient moisture to street trees, causing them to dry up, causing ground subsidence due to a drop in the groundwater level, and similar to car exhaust gas. , has become a social problem as a new type of urban pollution.

Problems to be Solved by the Invention This invention is a permeable tile block that is installed on a sidewalk or exterior structure, and allows rainwater to efficiently permeate into the ground through holes drilled in the permeable tile block. The aim is to provide tile blocks.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention is a tile block in which tiles are laid on the surface of the block, in which a through hole is drilled from the front surface of the block to the back surface of the block, and a permeable pipe is fitted into the through hole. When inserted, the permeable pipe is protruded from the back side of the block to form a claw part, a protector is provided at the base end of the permeable pipe, and a taper part is formed on the tile surface that slopes downward toward the through hole. It is an attempt to solve the above-mentioned drawbacks by providing a tile block.

Function The present invention allows water-permeable tile blocks to be laid on sidewalks or exterior structures, and allows rainwater to efficiently permeate into the ground through the holes drilled in the water-permeable tile blocks.

Embodiment An embodiment of the present invention will be described below based on the drawings. Reference numeral 1 is a tile block on which tiles 2, 2a... hole 3,3
a... is drilled.

Note that the through holes 3, 3a... are not limited to those drilled in the center of the tiles 2, 2a... as shown in this embodiment, but may be formed in the tiles 2, 2a... due to aesthetic, manufacturing, and functional aspects.
2a... The end portion or the joints 4, 4a... between the tiles 2, 2a... may be bored.

Next, to explain the manufacturing method of the water-permeable tile block according to the present invention, a through hole 3 is formed in the center of a predetermined formwork (not shown).
The tiles 2, 2a... having holes 3a... are arranged in a grid pattern, and a latex-based adhesive 5 is applied to the adhesive surface 7 of the cloth 6.
After placing a retractable cushion material (not shown) made of sponge on the upper surface of the cloth 6, the cushion material is pressed against the surface side of the cloth 6, and then the cushion material is The tiles 2, 2a are contracted downward, and the adhesive surface 7 of the cloth 6 coated with the adhesive 5 is tightly pressed and adhered to the surface of the tiles 2, 2a. The cloth 6 is bent and formed in the recesses 8, 8a.
It causes the formation of...

9, 9a... are vinyl chloride water permeable pipes vertically inserted into the through holes 3, 3a... from the back side of the tiles 2, 2a..., and the base ends of the water permeable pipes 9, 9a... are fitted with protective equipment 10, 10a, etc. for preventing the intrusion of dirt, pebbles, etc.

Next, from the back side of the tiles 2, 2a... into the joint parts 4, 4a... and into the block part 11, joint materials 12, 12a... made of concrete and block material 1 are introduced.
According to this manufacturing method, it is possible to obtain beautiful joints 4, 4a, etc., which fit well with the surfaces of the tiles 2, 2a, etc.

Incidentally, the ends of the water permeable pipes 9, 9a... are partially protruded from the block part 11 to form claw parts 14, 14a...
I will make it happen.

Next, to explain the function of the permeable tile block according to the present invention, when laying the permeable tile block on a sidewalk or outside structure, the tile blocks 1 are arranged in a grid pattern on the sand layer 15 on the flattened ground. If the claws 14, 14a of the pipes 9, 9a... are dug into the sand layer 15 and firmly fixed, rainwater can efficiently permeate underground through the permeable pipes 9, 9a... be.

It should be noted that the present invention is not limited to the configuration of the above-mentioned embodiment, but can be embodied by arbitrarily changing the shape of each part. For example, as shown in FIGS. 2, 2a...The surface side is provided with a tapered part 16, 16a... which slopes downward toward the through hole 3, 3a... drilled in the center, so that rainwater stagnates on the surface of the tile 2, 2a... The water permeates into the ground through the inside of the permeable pipes 9, 9a efficiently without any problems, and the uneven surface prevents slipping, and cutouts 17, 17a are provided on the back side of the tiles 2, 2a. Tile 2, 2a...
may be firmly fixed by joint materials 12, 12a, . . . and block material 13.

[Effect of idea]

In short, the present invention has two tiles on the surface of the block.
In the tile block 1 on which the tiles 2a... are laid, through holes 3, 3 are formed from the front surface of the block to the back surface of the block.
Since holes a... are drilled, when the water-permeable tile block is installed on a sidewalk or outside structure, rainwater can efficiently permeate into the ground through the holes 3, 3a... drilled in the water-permeable tile block. It can prevent flash floods and flooding of houses that occur during the rainy season and typhoon season, supply sufficient moisture to roadside trees, prevent lowering of groundwater level and ground subsidence, and can also be used to prevent through holes 3, 3a... At the same time as the permeable pipes 9, 9a are inserted, the permeable pipes 9, 9a are protruded from the back side of the block to form claws 14, 14a, so that the claws 14, 14a are firmly pressed into the sand layer 15. Since it is fixed and plays the role of an anchor, it is possible to prevent horizontal movement and improve the adhesion between the tile block 1 and the sand layer 15. At this time, the permeable pipes 9, 9a... are hollow inside. It is easy to fit into the sand layer 15, the sand is located on both the inside and outside of the permeable pipes 9, 9a, and the fixing state is improved, and rainwater is directly guided into the sand layer 15 for efficient infiltration. is completed, and protectors 10, 10a... are installed at the base ends of the water permeable pipes 9, 9a...
Since the water permeable pipes 9, 9a... are provided, the through holes 3, 3a... are caused by weathering around the through holes 3, 3a...
Protective equipment 10, 1 can prevent blockage.
0a... can prevent foreign matter from entering the through holes 3, 3a... and clogging the through holes 3, 3a..., and as a result, the penetration of rainwater is permanently ensured. In addition, since tapered parts 16, 16a, which slope downward toward the through holes 3, 3a, are formed on the surfaces of the tiles 2, 2a, rainwater can be stagnated on the surfaces of the tiles 2, 2a. It has great practical effects, such as allowing rainwater to penetrate into the ground efficiently and preventing slipping due to its uneven surface.
