ネプラス工法とは

「ネプラス工法」では、サイドカッティングマシンの開発により側溝の上部だけを切断して修繕するため、従来の工事に比べて3分の1から4分の1の施工時間を実現しました。 また、修繕箇所の長さが10メートル前後であれば、工事は1日で完了しますので交通規制は即日解除され、車輌の通行は最小限の時間で開放することができます。 改修用製品には大きく分け横断タイプ、縦断タイプの2種類があります。 施工箇所の条件により使い分けています。 ネプラス工法は、道路を横断して布設されている側溝、ブロック塀などの構造物に沿って布設されている側溝にその威力を発揮し用水路や流雪溝、集水桝などにも対応しています。

Construction Method: Introduction to the Neplus Method

80% reduction in concrete waste! We will proceed with repair work smoothly and quickly!

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!
