Street drainage ditch
Demonstrated effectiveness in actual rainfall! This is the ideal drainage ditch for countering guerrilla rainstorms.
The drainage gutter has a structure that is more than four times wider at the bottom than at the top of the water collection opening, making it less prone to clogging compared to traditional drainage slit structures. Continuous slits are processed at 500mm intervals at the base of the apron curb, allowing for efficient drainage of surface water. Instead of concentrated drainage through a catch basin, it features continuous drainage at two locations per meter, which is effective for overflow prevention during heavy rain. 【Features】 ○ Structure that is more than four times wider at the bottom than at the top of the water collection opening ○ Less prone to clogging ○ Continuous slits processed at 500mm intervals at the base of the apron curb ○ Efficient drainage of surface water ○ Effective for overflow prevention during heavy rain For more details, please contact us or download the catalog.

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.
