We would like to introduce a case study of our "U-shaped drainage channel." It was adopted for the construction of sediment control dams in mountainous areas where transportation and construction are difficult, and it was constructed as a permanent waterway by providing foundation work and edge concrete protection. Being made entirely of resin, it is highly resistant to corrosion, and compared to conventional U-shaped channels, it is significantly lighter, making it possible to construct in mountainous areas and steep slopes where rapid supply and on-site pouring are required, leading to reduced construction costs and shortened construction periods. *It can be easily installed by amateurs due to its bolt and nut assembly design. Additionally, it offers flexibility to arrange in a curved layout according to the terrain and to bend the waterway downward freely. 【Construction Overview】 - Waterway Width: 180mm/240mm/300mm/400mm/500mm/600mm - Total Length: 1150mm to 1180mm (Effective Length 1000mm) - Weight: Approximately 4.5kg to 13kg - Material: (Body) High-Density PE, (Reinforcement Angle) Rigid PVC - Color: Black *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where our "Polyethylene U-shaped drainage channel" was adopted at a disaster recovery site. During the emergency restoration work due to heavy rain disasters in Hiroshima Prefecture, our product was introduced as a "temporary waterway." (See product photo) Weighing approximately 4 to 13 kg, it can be transported and installed manually, allowing for smooth on-site operations. Additionally, due to its lightweight nature, it can be transported in large quantities by truck, contributing to rapid on-site responses with short delivery times. *With a standard length of 1 meter, it is easy to handle on-site and can be removed easily. It is suitable for construction in narrow areas where heavy machinery is difficult to bring in, steep slopes, and sites requiring restoration work after disasters. 【Features】 - Lightweight and easy to handle, allowing for quick installation and removal. - High strength secured by L-shaped horizontal angles and special T-shaped crossing angles. - Easy position and length adjustments on-site. - Floating prevention auxiliary angles secured by bolts. - Flexible construction that adapts to the terrain's unevenness. *For more details, please download the PDF or feel free to contact us.
