Rectangular cross-section drainage channel for side ditches "Kukei waterway"
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.
