Taiyo Industry Co., Ltd.
Developed “Highway Delta”, a disaster prevention product that replaces large sandbags.
Supporting rapid recovery in the event of a road disaster
Taiyo Kogyo Co., Ltd. (Tokyo Headquarters: Setagaya-ku, Tokyo; Osaka Headquarters: Yodogawa-ku, Osaka; President: Yuki Nomura), which handles large-scale membrane structures (tent structures), civil engineering, and logistics materials, was hit by a road disaster. Central Japan Highway Maintenance Central Co., Ltd. (Headquarters: Hachioji City, Tokyo; President: Tomohito Kawai) jointly developed and manufactured a temporary large water bag called “Highway Delta” that replaces sandbags to support the rapid recovery of time. It was started. “Highway Delta” will be sold from January 2023 by Central Japan Highway Maintenance Central Co., Ltd. to companies and local governments that undertake road maintenance and repair work

Landslides, debris flows, landslides, and other landslide disasters have been on the rise in recent years. According to the Ministry of Land, Infrastructure, Transport and Tourism, in the 10 years until 2021, the annual average number of occurrences has increased by about 1.3 times compared to the previous 10 years (Landslide disasters in 2021/Ministry of Land, Infrastructure, Transport and Tourism Sabo Department) . When such a landslide disaster occurs on a road slope, it is necessary to prevent further muddy water and stones from entering the road after taking emergency measures such as removing the earth and sand. “Highway Delta” is a temporary large water tank to prevent such muddy water and stones. It is a long triangular bag made from a highly waterproof sheet that is stretched out and laid down, and by injecting water into it, it becomes a strong water bag. As a disaster prevention tool that replaces conventional sandbags (tonpacks), it is lightweight, can be folded compactly, can be stored easily, and can be quickly installed. Since it can be used any number of times, it is environmentally and resource-friendly.
Based on our flood damage countermeasure product “Delta Tube”, this product has been improved into a product that can be used on the roadside in about a year and a half in cooperation with Central Japan Highway Maintenance Chuo Co., Ltd. We reviewed the shape of the triangle and commercialized it by equipping it with items necessary for roadsides, such as arrow reflectors and protective mats that make it easier to see the direction of the road.
・ Can be transported to the site in a stored state compared to the conventional method (installation of large sandbags)
2. Labor saving
・ Heavy equipment is required to install large sandbags, but highway delta is not required.
・There is no need for back-and-forth work for transportation ・When installing one unit, installation is completed in 15 minutes by 4 workers *When using the water truck at Central Japan Highway Maintenance Center 3. Reusable
・In the case of sandbags, they may be damaged during removal and the earth and sand may be scattered.
・If you use bags for salt for snow and ice (sodium chloride, etc.), it may be necessary to dispose of waste after removal.
4. Road user safety
・ In the case of large sandbags, there is a high possibility that a collision will lead to a serious accident. Highway Delta can mitigate the impact of collisions due to water sacs
