Introduction of case studies using polyethylene U-shaped ditches: Temporary water channels for disaster recovery.

Introduction of case studies using polyethylene U-shaped ditches: Temporary water channels for disaster recovery.

"Active in recovery work for heavy rain disaster" Adopted as an emergency and temporary waterway at sites requiring restoration to original condition! Contributes to smooth on-site work due to being lighter compared to regular U-shaped gutters.

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 following the heavy rain disaster 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 well-suited for construction in narrow areas where heavy machinery is difficult to bring in, steep slopes, and sites requiring restoration after disaster recovery work. 【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. - Auxiliary angles to prevent lifting through bolt fixation. - Flexible construction that adapts to the terrain's unevenness. *For more details, please download the PDF or feel free to contact us.

【U-shaped ditch utilization example】Construction of a sediment control dam in a mountainous area.

【U-shaped ditch utilization example】Construction of a sediment control dam in a mountainous area.

Introducing examples of U-shaped ditch utilization for measures against landslides in mountainous areas and for river management and conservation works!

We would like to introduce examples of the use of our "U-shaped gutters." They have been adopted for sediment control dam construction in mountainous areas where transportation and construction are challenging, and were constructed as permanent waterways by protecting the foundation and edge concrete. Being made entirely of resin, they are resistant to corrosion and, compared to standard U-shaped gutters, are significantly lighter, allowing for construction even in mountainous areas and steep slopes where rapid supply and on-site pouring are necessary, leading to reduced construction costs and shortened construction periods. *They can be easily installed by amateurs due to their bolt and nut assembly design. Additionally, they offer flexibility in arrangement to fit the terrain, allowing for curved configurations and the ability 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.
