A versatile waterway that can accommodate all conditions.
It can accommodate all site conditions such as road gradient, embankment shape, land width, and flow rate. Additionally, the width and depth of the waterway and the top slope can be adjusted freely, allowing for flexible design cross-sections. The vertical side walls also make installation easy.
This is a rectangular cross-section water channel for ditches that enables a reduction in the height of drainage pipes.
The "Kukei Waterway" was developed for side ditches such as box tunnels. The roads established underground are divided into the space for vehicle passage and the lower surface where road drainage side ditches are installed. The most significant factor in determining the depth of the lower surface when planning underground structures like tunnels is the height of the road drainage structures. The "Kukei Waterway" significantly reduces height while maintaining performance equivalent to conventional drainage channels in both the waterway and the chamber sections, allowing for a reduction in the excavation depth of underground structures and a smaller size of the structures themselves, thereby lowering overall construction costs. 【Features】 - Design load corresponds to T-25 longitudinal wheel load - Complies with the Ministry of Land, Infrastructure, Transport and Tourism Kinki Regional Development Bureau Design Guidelines, Volume 3, Road Edition - Over 30% lower in height compared to circular waterways and covered open waterways - The drainage inlets for road surface drainage ensure sufficient drainage capacity through drainage experiments - Packing material is used in the joint sections For more details, please contact us or download the catalog.

We will introduce various special adaptations, including drop work, curve adaptation, and drain adaptation!
Here are some examples of special adaptations in L-shaped waterways. In "drop structures," anchor reinforcement bars are installed from the drop section products. When "considering internal water pressure in the design," the bottom slab cast on site will have double reinforcement. Additionally, there are examples such as "curve adaptations" and "drain adaptations (buoyancy prevention measures)." For more details, please refer to the related catalog. 【Examples of Special Adaptations】 ■ Drop Structures ■ Curve Adaptations ■ Considering Internal Water Pressure in the Design ■ Drain Adaptations (Buoyancy Prevention Measures) *For more information, please refer to the PDF materials or feel free to contact us.
