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. Recently, waterway members made of hard resin, which is much lighter than concrete waterway members, have also 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 caused the foundation to collapse.

The present invention improves these problems and can be used for a long period of time in cold regions, does not require special treatment of the foundation inside the drainage canal, and has a certain degree of flexibility, so it can be used for the foundation. To provide an adjustable rubber water channel member that can easily follow a somewhat uneven surface and can freely follow a grooved surface of a drainage channel.

(Means for Solving the Problems) That is, the present invention is characterized by a rubber channel member in which a core material is embedded in a sheet of rubber, and the core material is made of a plastically deformable metal member. This is a rubber water channel member whose shape can be adjusted.

The rubber water channel member of the present invention has an elongated U-shape, but the U-shape can be freely changed at the construction site depending on the groove shape of the drainage channel.
In addition, it is easy to follow the uneven surface of the foundation of the drainage channel,
Since there is no need for special foundation treatment, economical construction becomes possible.

(Embodiments) Hereinafter, embodiments 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, and the rubber water channel member 1 of the present invention is made of natural rubber,
A core body 3 made of a metal wire mesh or a metal flat plate is embedded in a sheet-like rubber material 2 made of isoprene rubber, chloroprene rubber, ethylene-propylene terpolymer with good weather resistance, butyl rubber, or a blend thereof. , the cross section is approximately U
It has a relatively long and narrow shape, approximately 50 to 200 cm in length. 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.

As mentioned above, the core body 3 is a metal member made of a metal wire mesh or a metal flat plate, and this member has the function of maintaining the shape of the rubber channel member 1 and the function of freely changing the shape of this member. It's on. Therefore, this metal member has a porosity R={a/(a+
d)} ² × 100 (a: opening, d: wire diameter) 30 to 95, and plain weave, twill weave, crimp weave, diamond-shaped wire mesh, hexagonal wire mesh, etc. can be used. In addition, the metal flat plate is approximately 0.02 to 1 mm thick and has multiple round and square through holes, and the ratio of through holes (area of through holes / flat plate area x 100) is approximately
It is 10-70%.

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 8 provided in a vacant lot, developed land, or the like. At this time, if the dimensions of the water channel member 1 are larger than the dimensions of the drainage channel 8, the corner portion 6 may be deformed by pressing the vicinity of the top 5 of the channel member to align with the side wall 7 of the drainage channel. becomes possible.

However, since it cannot be transformed into the conventional water channel member 8, it is necessary to re-dig the drainage channel if it does not fit the dimensions of the drainage channel.

(Effects) As described above, the rubber waterway member of the present invention has a plastically deformable metal member embedded as a core in the sheet-like elastic rubber, and does not leak fluids such as water into the base. In addition to its basic performance as a water channel component, it is possible to freely change the shape of the channel component according to the shape of the drainage channel at the construction site, and by having a certain degree of flexibility, it is possible to improve the condition of the underlying ground. Since it is easy to follow even somewhat uneven surfaces, there is no need to treat the base of the drainage channel, resulting in highly economical construction, and the waterway member has excellent shape retention due to the core body of the metal member. Also, since it is made of rubber, it has excellent impact resistance, so it does not break easily, and it is also lightweight, making it easy to install in drainage channels.

Furthermore, even when the rubber waterway member of the present invention is used in a cold region, the joints of the waterway member are less likely to be damaged due to freezing, and can be used for a long period of time.
