HGPU type gutter B300/B400
The flow in the vertical direction can be used in a water-compatible manner! It enhances water collection and drainage!
The "HGPU type drainage channel B300/B400" is a product that can be used similarly to the GPU3 type drainage channel (B300-H300, B400-H400). One side is raised by 30mm, reducing the flow of rainwater that collects due to the cross slope into adjacent farmland or residential areas. In cut sections, it reduces erosion on the roadside, and in fill sections, it decreases the risk of soil collapse. 【Features】 ■ Can be used for longitudinal flow in a water-compatible manner ■ Usable similarly to the GPU3 type drainage channel (B300-H300, B400-H400) ■ The PC4 channel cover (B300, 400) is also the same ■ Enhances water collection and drainage capabilities ■ Reduces erosion on the roadside in cut sections and decreases soil collapse in fill sections ■ No hindrance for light trucks or agricultural machinery entering and exiting due to the height difference (30mm) *For more details, please refer to the PDF document or feel free to contact us.

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.
