In ensuring safety on highways, snow removal operations during snowfall are essential. However, there are frequent cases where the snow plow of snow removal vehicles gets caught on grates, causing damage. The damage to the grates not only threatens the safety of passing vehicles but also leads to traffic restrictions due to repair work, creating further risks. Our snow removal-friendly cast iron grates are designed to be less affected by snow removal vehicles, even with some height differences. This reduces the risk of grate damage and ensures safe passage on highways. 【Usage Scenarios】 - Snow removal routes on highways - Areas where height differences between grates and pavement are likely to occur - Areas with severe corrosion of grates due to de-icing agents 【Benefits of Implementation】 - Prevents damage from snow plows of snow removal vehicles - Significantly reduces restriction time due to immediate traffic reopening - The cast iron integrated structure makes the grates less prone to deformation, allowing for long-term use - The cast iron integrated structure improves corrosion resistance and durability

In areas with snowfall, there are many instances of grating damage due to snow removal. Particularly, when there is a step between the grating and the pavement surface, the risk of damage is high, and frequent repair work is currently being carried out. The Neplus method offers grating that is less affected by snowplows even with some step differences. The snow removal-friendly grating features a cast iron integrated structure that is corrosion-resistant and durable, significantly contributing to the reduction of lifecycle costs. 【Usage Scenarios】 - Cross-drainage ditches and access ditches on snow removal routes - Locations where steps between the grating and pavement surface are likely to occur (areas prone to ruts) - Areas where grating corrosion due to de-icing agents is severe 【Benefits of Implementation】 - Prevents damage from snowplow blades - Significantly reduces restriction time by allowing immediate traffic reopening - The cast iron integrated structure makes the grating body less prone to deformation, allowing for long-term use - The cast iron integrated structure improves corrosion resistance and durability

In the maintenance and management of ditches by local governments, consideration for surrounding residents and private property, as well as the impact of traffic congestion due to traffic regulations, are significant challenges. In particular, the renovation of aging ditches tends to lead to prolonged traffic regulations and increased costs due to excavation work. The Neplus method was developed to address these challenges. 【Usage Scenarios】 - Renovation of ditches in areas where traffic regulation is difficult, such as road crossings or in front of stores - Construction in locations close to underground installations or structures - Responding to needs for height adjustments of ditches (raising or lowering) due to road improvements - Resolving difficulties in construction caused by the depth of free-slope ditches 【Effects of Implementation】 - Shortening of traffic regulation periods due to immediate reopening of roads - No excavation required, avoiding impact on underground installations and private property - Potential cost savings through the reuse of existing covers - Significant reduction in construction time

Due to the height difference between the road and the drainage ditch, many drainage covers have been damaged during winter snow removal operations. In particular, the damage to grates can lead to tire punctures, which is very dangerous. To prevent such damage, some areas in snow-prone regions install drainage covers lower than the road surface. However, during non-snow periods, the height difference can hinder bicycle passage and lead to accidents, as well as cause noise and vibration when vehicles pass. By using the Neplus method for construction, the work can be completed in a short period.

• Gutters and U-shaped gutters

In conventional rolled gutter connection catch basins, the accumulation of fallen leaves obstructs the flow of water, making drainage impossible. The "Kansuke" rolled gutter connection catch basin directs drainage from the crown plate of the three-dimensional part, preventing surface flooding. By using the Neplus method for installation, replacement work can also be easily carried out.

"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.*
