Side Ditch Comprehensive Catalog Additional Publication

Achieving economy, strength, and durability, the two-row drainage channel and slit holes capture rainwater!

The "Win Side Ditch" is a new free-gradient side ditch that combines economic efficiency with strength and durability as a product. It features two rows (double) of drainage channels and slit holes arranged in the main beam and cover, effectively capturing rainwater. Thanks to its super drainage capacity, a collection grating is unnecessary. The slit holes are flared, making them less prone to clogging. 【Features】 ■ Two rows of drainage channels and slit holes effectively capture rainwater ■ Suppresses road surface subsidence ・ The side walls have a flat shape without irregularities ■ Lightweight cover significantly reduces construction costs ・ Excellent drainage function minimizes the need for grating ■ Prevents water accumulation on roads and rainwater runoff to residential areas *The sales area is limited to the Kinki region (2 prefectures and 4 counties) and the Kanto region.

Commercializing optimal drainage structures based on experimental data from industry, government, and academia. A circular waterway that maximizes the functionality of drainage pavement.

This is a circular drainage channel that demonstrates the drainage function of permeable pavement. It features a design structure with optimal drainage capabilities based on rainfall experiments. The inlet structure pursues the thinning of the permeable pavement layer at the collection area of the circular drainage channel. The circular drainage channels are strongly connected to each other with bolts. It is a design structure that comes as a set with the circular drainage channel and a dedicated catch basin.

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.

We will introduce examples of smart drains installed in roads, sidewalks, parking lots, and parks.

The steel side ditch for shoulder drainage, Smart Drain, ensures safety and allows for road width expansion. It also excels in water flow capacity and features a compact and space-saving design. Smart Drain is available in three types: S-type, E-type, and C-type, which can be selected according to the shape of the road. It can eliminate puddles on sidewalks and shoulders, allowing for manual installation with minimal excavation. This significantly shortens construction time and minimizes the impact on the surrounding area. For more details, please contact us or refer to the catalog.
