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.

In the "Neplus Method," the development of a side cutting machine allows for the cutting and repair of only the upper part of the drainage ditch, achieving construction times that are one-third to one-fourth of traditional methods. Additionally, if the length of the repair area is around 10 meters, the work can be completed in one day, allowing for immediate lifting of traffic restrictions and minimizing the time vehicles are blocked. There are two main types of repair products: cross-sectional type and longitudinal type, which are used according to the conditions of the construction site. The Neplus Method demonstrates its effectiveness along drainage ditches that run across roads and structures such as block walls, and it is also compatible with irrigation channels, snow-melting ditches, and catch basins. 【Construction Method】 1. Installation of running rails 2. Cutting of the drainage ditch 3. Removal of concrete 4. Drilling of bolt holes 5. Injection of special adhesive 6. Installation of the upper repair product for the ditch 7. Filling with concrete 8. Tamping of pavement materials *For more details, please refer to the PDF materials or feel free to contact us. *The construction method video is currently available at the link below!

• Renovation and repair methods

Road damage has been increasing year by year due to the rise in vehicle traffic. Among these, damage to the upper part of roadside ditches has worsened the living environment for local residents due to accidents caused by uneven surfaces, as well as noise and vibrations during vehicle passage. The Neplus method is an environmentally friendly new technology that offers numerous benefits such as cost reduction, resource and energy savings, and shortened construction periods. It has been adopted in various locations including expressways, national roads, and prefectural and municipal roads. 【Slit Type Construction Example】 Restoration of ditches with uneven surfaces to a flat condition. → The work is completed in one day, ensuring peace of mind for delivery locations. 【Bolt Fixed Type Construction Example】 Construction is possible in areas where long-term traffic restrictions cannot be implemented. → The height adjustment feature allows for alignment with cross slopes. *For more details, please contact us or download the PDF materials for review.

The "U Cap" is a method that allows for the reuse of existing drainage covers by only replacing the damaged types of covers or areas with severe rattling sounds. 【Construction Example】 ● Before Construction - There are steps that pose a tripping or slipping hazard. - It becomes rattly every time a vehicle passes. ● After Construction - The height difference is eliminated, and the grating is reused. - The cover and the drainage are integrated, eliminating any rattling. *For more details, please contact us or download the PDF materials to view. *The construction method video is currently available at the link below!

The Neplus construction method "Slit Type" is a recommended longitudinal type for roadside ditches and similar applications. It can accommodate various types of roadside ditches, not just flat roads. A hole of Φ20×20 mm is drilled, and approximately 20 mm of elevation is added, securing it with anti-shift rebar and filling. The inspection port is constructed using an embedded M20 adjustment nut. It is also possible to carry out construction even if a block excavation is close to the side ditch. *For more details, please contact us or download the PDF materials for review. *Videos are also currently available at the link below!

The Neplus method "Circular Drainage Ditch Compatible Type" is a recommended product for efficient drainage in circular ditches. It can be used in circular waterways with continuous drainage ditches, such as tunnels, and you can choose from two types: longitudinal and transverse, so please select the specifications according to the site conditions. An epoxy adhesive suitable for metal is used for filling. *For more details, please contact us or download the PDF materials to view.

The Nepuras method "Cross Type" is a product that allows for smooth drainage into ditches and other areas, featuring embedded parts such as grating. The Nepuras method "Angle Type" allows for the selection of materials based on site conditions and load requirements. By checking the size of the side ditches and the construction locations for the Cross Type, Longitudinal Type, grating, concrete covers, etc., a balanced Nepuras method is completed, taking into account economic efficiency, strength, durability, and workability. *For more details, please contact us or download the PDF materials to view.

The Neplus method "Soundproof Type" is suitable for locations where stores or residences are adjacent to drainage ditches and excavation cannot be performed, or where excavation cannot be done at parking lot entrances or retaining walls. By using the soundproof type, noise such as rattling sounds can be prevented. In conventional methods, the work takes 4 to 5 days, but the Neplus method can be completed in one day, making it safe to use even in stores, residences, and busy parking lots. 【Comparison with Conventional Methods】 ● Conventional Method Survey → Temporary Closure → Pavement Slab Crushing → Mechanical Excavation → Foundation Work → Drainage Ditch Installation → Pavement Restoration → Completion - Days: 4-5 days - Asphalt Waste: 0.30 m² - Excavated Soil Volume: 30.5 m² - Concrete Waste: 0.87 m² ● Neplus Method Survey → Cutting → Installation of Renovation Products → Backfilling Material → Installation of Cover Plate → Completion - Days: 1 day - Asphalt Waste: 0 m² - Excavated Soil Volume: 0 m² - Concrete Waste: 0.17 m² *For more details, please contact us or download the PDF materials for review.

With the Neplus method 'buried type', even in large waterways, design blocks, and painted sidewalks, everything except the grating can be buried, ensuring proper drainage without interfering with the design, allowing for paving. In the conventional method of completely replacing the gutters, there is waste involved as the surrounding area needs to be excavated, the existing gutters removed, and new gutters installed. The Neplus method uses a lateral cutting machine, allowing for paving in a short period. *For more details, please contact us or download the PDF materials to view.

"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.*
