Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a rubber waterway member, and more specifically, it can be used to freely conform to the shape of a U-shaped drainage channel formed in vacant land, farmland development, or roadside ditches. The present invention relates to a rubber waterway member that can be used.

(Prior Art) Conventionally, concrete waterways have been continuously laid in drainage channels created when creating vacant land or farmland. Also, recently, materials made of hard synthetic resin, which is much lighter than concrete waterway members, have been used.

(Problem that the invention aims to solve) However, since conventional concrete waterway members are heavy, it is necessary to treat the base with gravel, crusher run, sand sprinkling, etc., and also to adjust the level of the waterway member with concrete. . In addition, conventional waterway members made of concrete or hard resin are rigid bodies, and when used in particularly cold regions, water contained in the surrounding soil that comes in contact with the waterway members freezes and damages the waterway members. When lifted, the joints developed cracks and failures, which eroded the underlying foundation and led to further collapse of the foundation.

In addition, when the above-mentioned waterway member is installed in a drainage channel on a slope, water generated by heavy rain, heavy snow, etc. flows out from the upstream side of the slope as surface water or underground water, and this water flows near the waterway member. The holding capacity of the soil was reduced and the soil was washed away. As a result, the soil near the channel members disappeared in a short period of time, and soil had to be added again.

The present invention is intended to improve these problems, and aims to provide a rubber waterway member that prevents the flow of soil near the waterway member installed in a drainage canal and can be constructed economically. purpose.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention is a rubber having a substantially U-shaped cross section, in which a plastically deformable metal member is embedded in the rubber as a core. The water channel member is characterized in that a water intake hole is provided on at least one side of the rubber channel member, and the water intake hole is covered with a filter.

(Example) Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

Fig. 1 is a perspective view of a rubber water channel member according to the present invention in which a hole for taking in water is provided only on one side. A rubber material 2 made of a highly resistant ethylene-propylene terpolymer, butyl rubber, or a blend thereof, and a core 3 made of a wire mesh or a flat metal plate.
It has a roughly U-shaped cross section and about 50 to 200
It has a relatively long and narrow shape of about cm. There is a step part 4 with a thin wall on the inside of one end of the water channel member 1, and a step part 4 with a thin wall on the outside of the other end, and a part where it joins with other water channel members. It's getting old.

Furthermore, water intake holes 5 are uniformly provided on one side 9 of the rubber water channel member 1, and the entire surface where the water intake holes 5 are present is covered with a filter 6. The water intake hole 5 is not provided in a portion where water flows, at least in a portion less than about 50 mm from the bottom of the side surface 9.

The diameter of the water intake hole 5 is suitably in the range of 2 to 20 mm. When the pore diameter is less than 2 mm, the fibers of the filter are likely to be clogged with gravel and soil, and when it is larger than 20 mm, the strength of the filter against the pressure of gravel and soil becomes a problem. Also, the hole pitch is 20 to 100.
If the appropriate pitch is less than 20 mm, the strength of the side surface 9 of the channel member will decrease, and if it is greater than 100 mm, the water permeability will deteriorate and the effect will become weaker.

As mentioned above, the core body 3 is a metal member such as a wire mesh or a flat metal plate, and this member has the function of maintaining the shape of the rubber waterway member 1 and the function of freely changing the shape of the rubber waterway member 1. I'm in charge. Therefore, this metal member has a porosity R={a/a+d}
² × 100 (a: opening, d: wire diameter) is 30 to 95, plain weave, twill weave, crimp weave, rhombus wire mesh,
Materials such as tortoise shell wire mesh can be used. In addition, the metal flat plate is about 0.02 to 1 mm thick and has multiple round and square through holes, and the ratio of the through holes (area of the through hole / flat plate area x 100) is approximately 10 mm.
~70%.

Further, the filter 6 used in the present invention has a function of taking only water into the water channel member 1 without pouring earth and sand in the soil, and can be made of, for example, woven or non-woven fabric. Among these, needle-punched nonwoven fabrics made of polyester, polypropylene, etc., and thermal adhesive type nonwoven fabrics are superior in terms of strength, weather resistance, heat resistance, antiseptic properties, and high water permeability. It is suitable and does not easily clog. The basis weight of nonwoven fabric is approximately 20~
A range of 1000g/m _U2 is preferable, and if it is smaller than this range, the fabric will be too coarse and will allow dirt to pass through, and if it is too large, water permeability will be poor.

Next, an example of the use of the rubber water channel member 1 will be explained using FIG. 2. The rubber waterway member 1 is installed in a drainage channel 10 provided in a vacant land development site or the like. At this time, if the dimensions of the water channel member 1 are larger than the dimensions of the drainage channel 10, the corner portion 8 can be deformed by pressing the vicinity of the top 7 of the channel member so as to be aligned with the side wall of the drainage channel. It is possible.

However, since conventional water channel members cannot be deformed, it is necessary to re-dig the drainage channel when the dimensions of the channel do not suit the dimensions of the channel. The rubber water channel member 1 is installed as described above and is in the state shown in FIG. 3. Water penetrates into the soil in the direction of the arrow from above the slope in FIG. 3 and is stored in the soil 11 next to the rubber channel member 1. The water flows into the water channel member 1 through the water intake hole 5 . Because of the filter 6, the earth and sand in the soil 11 next to the water channel member 1 do not flow into the water channel.

Moreover, what is shown in FIG. 4 is a structure in which water intake holes 5 are opened on both sides of the water channel member 1 when the slopes on both sides are upward slopes. The covering position of the filter 6 for preventing dirt and the like from entering the waterway is not limited to only the outside of the side surface of the waterway member 1, but may be on both sides.

(Effects) As described above, the rubber waterway member of the present invention prevents soil from being washed away to the side of the waterway by providing holes on the side of the waterway member to take water in the soil into the waterway. In addition, by installing filters such as non-woven fabric in the holes that take water in the soil into the canals, only water can be taken into the canals, preventing sediment, etc. next to the canals from flowing into the canals, preventing surface water, seepage water, etc. It efficiently processes water and spring water, and has a certain degree of flexibility, making it easy to follow the uneven surface of the underlying ground, making it possible to construct economically without the need for foundation treatment. be effective.
