Introduction of case studies using polyethylene U-shaped gutters: Temporary waterways for disaster recovery.
"Active in heavy rain disaster recovery work" Adopted as an emergency drainage channel at sites requiring restoration to original condition! Its lightweight compared to standard U-shaped gutters contributes to smooth on-site operations.
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.
