FR cross drainage ditch and FR catch basin (longitudinal slope compatible slope cross drainage ditch and slope catch basin)
Continuously adapts to the longitudinal gradient of the road, enabling smooth vehicle operation!!
The "FR Cross Drainage Ditch and FR Catch Basin" is a slope-crossing drainage ditch and catch basin designed to accommodate the longitudinal gradient of the road without steps. In conventional methods, the installation of ditches and basins horizontally caused changes in gradient, leading to noise during vehicle operation and damage to the ditches and basins due to impacts. The FR Cross Drainage Ditch and FR Catch Basin are installed in accordance with the longitudinal gradient of the road, enabling smooth vehicle movement. This resolves noise issues and reduces impacts on the ditches and basins, thereby minimizing deterioration such as damage and improving safety. 【Features】 - The bottom of the ditch and basin is arc-shaped, allowing for step-less longitudinal gradient adjustment when combined with a dedicated base. - Both the base and the main body are precast products, enabling a reduction in construction time by approximately 50% compared to conventional methods, which is expected to ease traffic restrictions. - The surfaces of the grating and receiving frame are textured, which is expected to reduce vehicle slipping.

Bridge curb and drainage ditch FD drain
It has a double safety structure to prevent the lid from popping up and scattering.
The FD drain, which serves as a curb and drainage channel for bridges, features a double safety structure that prevents the cover from bouncing up and scattering. The underlying SG (melted zinc-aluminum alloy) coating has several times the corrosion resistance of standard hot-dip galvanized coatings, providing excellent rust prevention. Additionally, it has superior adhesion to various types of paint, ensuring that there is no concern about peeling over time. The nylon 12 coating maintains an average thickness of over 300μm, effectively blocking moisture from the iron substrate and underlying coating, thus achieving a long lifespan. Its excellent wear resistance means that even in harsh environments like road shoulders, it is less likely to chip or peel. For more details, please contact us or refer to the catalog.

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.
