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.
Registered with NETIS! We flexibly accommodate the longitudinal slope of the road.
The "FR Cross Drain / FR Catch Basin" is a cross drain and catch basin that can accommodate the longitudinal slope of the road in a stepless manner. It can handle longitudinal slopes of up to 15%, ensuring smooth vehicle movement without any changes in slope. There is no need for cutting the drain or on-site pouring, which can significantly shorten the construction period. 【Features】 ■ Steplessly accommodates the longitudinal slope of the road ■ Ensures smooth vehicle movement without changes in slope ■ No need for cutting the drain or on-site pouring ■ Can significantly shorten the construction period *For more details, please feel free to contact us.
Non-slip effect enhanced with anti-slip processing!
The "PU3 type cross drainage ditch" is a road drainage ditch that simplifies construction and significantly shortens the construction period. With bolt fixation (using sound-absorbing rubber), it excels in soundproofing effects, and the anti-slip processing enhances non-slip effectiveness. Additionally, sizes range from 250 to 500 A and B, accommodating most on-site cross drainage needs. 【Features】 ■ Cost reduction ■ Reduced impact on traffic ■ Compatible with T-25 ■ Enables reliable compaction work ■ Significantly shortens construction period *For more details, please refer to the catalog or feel free to contact us.
NETIS Registration: CB-100060-A (Old Number) Soundproof Type Free Slope Drainage 'OS Drain'
○ The soundproof (noise-reducing) type free gradient ditch, which adds soundproofing functionality to the conventional free gradient ditch (variable ditch) and eliminates protrusions on the sides, is becoming mainstream. Among them, this OS ditch possesses numerous excellent features that are not found in other companies' soundproof variable ditches. ○ This is a soundproof type free gradient ditch designed to guide rainwater from the road surface into the ditch. (Multifunctional free gradient ditch) ○ The soundproof type free gradient ditch "OS ditch" is a low-carbon concrete product made using blast furnace slag fine powder.
Roadside ditch crossing (OD-250･300A･300B) T-25
A side ditch used in connection with roads, land, and drainage channels.
L-shaped drainage ditch according to JISA5372 Appendix E recommended specification E-4 and JISA5371 Appendix C recommended specification C-1.
■L-shaped drainage channel JISA5372 - Mainly used for mount-up types below 100mm. ■L-shaped drainage channel JISA5371 - It is rare for vehicles to run adjacent to each other, and even when they do, it is in places where they run at low speeds, such as during temporary stops, and is installed parallel to the roadway.
