Leaf Fall Flood Prevention Lid "Kansuke"

Leaf Fall Flood Prevention Lid "Kansuke"

It demonstrates its power even in sudden guerrilla downpours. Even when leaves and debris accumulate, it maintains drainage performance to solve road flooding!

"Kansuke" is a product that combines L-shaped drainage channels for fallen leaves and flood prevention with universal design grating for bicycles. It can also be installed using the Neplus method for repairing roadside ditches. Even if clogging occurs on the grating, drainage is maintained through the drainage holes on the vertical sections. **Features of Kansuke** - **Enhanced drainage performance at the L-shaped channel curb!** To address flooding caused by sudden heavy rain or concentrated downpours, drainage holes have been added to the curb section to improve drainage performance. This prevents flooding even when there are obstacles like fallen leaves or newspapers and magazines that could hinder drainage, thanks to stable drainage performance. - **Compatible with the Neplus method (drain cover repair)** The Neplus method, which has brought innovation to roadside ditch repair work, allows for the replacement of only the damaged parts, shortening construction time, reducing waste, and requiring fewer materials, making it a groundbreaking method. - **Supports safe cycling** By changing the shape of the grating to a triangular pitch, it prevents wheels from getting stuck or falling in. Additionally, the incorporation of anti-slip protrusions in the components has improved slip resistance. *For more details, please contact us or download the PDF materials for further information.*

[Construction Example] Certain Clinic Checker Plate Replacement Work

[Construction Example] Certain Clinic Checker Plate Replacement Work

This is a case study of replacement work due to corrosion of the parking lot's septic tank cover and receiving frame.

Here is an example of the replacement work for the cover of a septic tank in the customer parking lot of a certain clinic. The existing SUS cover and frame at the site were corroded and deteriorated, posing a risk of sagging and falling whenever a vehicle drove over them. We adopted a corrosion-resistant FRP cover that can withstand the weight of vehicles. The existing frame was removed, and a new SUS frame was installed. 【Construction Example】 ■ Production Time: Approximately 1.5 months ■ Type of Work: Equipment Installation ■ Work Days: 2 days ■ Date/Location: December 2019/Saitama Prefecture ■ Equipment Used: FRP rectangular manhole, SUS frame *For more details, please refer to the PDF document or feel free to contact us.
