Drop cover type U-shaped drainage ditch according to JISA5372 Appendix E recommended specifications E-2.
Type 1 is primarily installed on sidewalks. Type 3 is rarely adjacent to vehicles, and even when it does occur, it is installed parallel to the roadway in places where vehicles travel at low speeds, such as during temporary stops.
A ditch that can properly set the drainage slope and form a vertical rectangular flow section.
■It can set the drainage slope appropriately and form a vertical rectangular water flow cross-section. ■It is designed for a 25-ton vehicle. ■Due to its frame structure, the overall strength is balanced. ■To support product arrangement suitable for the site, the side wall height is standardized in 10 cm increments. ■A wide variety of types are available, including for adjusting fractions, corner cuts, support line installations, and cross sections.
![Deep groove circular side ditch Top lifter specification [CAD data provided]](https://image.www.ipros.com/public/product/image/273/2001252749/IPROS2344047430003097221.jpg?w=280&h=280)
Top lifter compatible! The price is less than half that of our own grating products! Adopted for design at Sendai Freight Terminal Station! Available for delivery to other prefectures!
We would like to introduce the "Deep Groove Circular Drain - Top Lifter Specification" that we handle. This product is compatible with the FD280 top lifter. The circular bottom surface of the waterway provides a flushing effect, making it difficult for sediment to accumulate. Additionally, it allows for variable invert casting, and the standard sizes range widely from 300×300 to 500×1200. Our key service areas include the Kanto region, such as Ibaraki Prefecture, Gunma Prefecture, Fukushima Prefecture, Tokyo, Kanagawa Prefecture, Chiba Prefecture, and Saitama Prefecture, so please feel free to contact us. 【Features】 ■ It is a side ditch used in cargo terminal container yards. ■ It is difficult for sediment to accumulate. ■ Standard sizes range widely from 300×300 to 500×1200. ■ Variable invert casting is possible. ■ There are products that also prevent chemical runoff. ■ Nationwide delivery is possible using trailers and freight trains. *For more details, please refer to the PDF materials or feel free to contact us. *CAD data is also available for download!
A structure that maximizes retention and infiltration capacity! It excels in maintenance management, functionality, and workability.
We handle "FX permeable gutters and adjustable gutters." The FX permeable gutter adopts a slit hole structure that does not get blocked by crushed stone. In construction work such as land development and parcel consolidation, as well as in large store parking lots, making these gutters permeable is essential for drainage improvement, allowing for significant design changes without compromising aesthetics while effectively controlling rainwater runoff. Permeable gutters can widely permeate relatively shallow ground, providing moisture to trees and being effective in preventing global warming. 【Features】 ■ Adopts a structure that does not hinder permeability ■ Resistant to clogging ■ Cost reduction ■ Excellent in maintenance management, functionality, and workability ■ The FX permeable gutter adopts a slit hole structure that does not get blocked by crushed stone *For more details, please refer to the PDF materials or feel free to contact us.
It can also be used as a bicycle path-compatible type! It is a box-shaped drainage system that can accommodate various pavement thicknesses.
"All Weather" is a box drainage system designed with an increased number of side drainage holes to accommodate permeable pavement, allowing for more even and efficient drainage. The position of the side drainage holes can be adjusted to accommodate various pavement thicknesses. To ensure smooth water flow during low water levels, the bottom of the pipe channel is shaped in an R-type, minimizing sediment accumulation even during prolonged good weather. Additionally, we offer options that place greater emphasis on anti-slip effects, such as the "All Weather Non-Slip Type" and "All Weather Bicycle Path Compatible EJ." 【Features】 ■ Allows for more even and efficient drainage ■ The position of the side drainage holes can accommodate various pavement thicknesses ■ Excellent at collecting water runoff, minimizing water accumulation in the entry areas ■ Reduces sediment accumulation even during prolonged good weather ■ Can be used as a bicycle path compatible type with an apron width of 80mm and an apron slope of 2% *For more details, please refer to the PDF materials or feel free to contact us.
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.
Circular waterway with continuous drainage ditches in the longitudinal direction.
It is a product that possesses five characteristics: economic efficiency, functionality, high constructability, high quality, and beauty.
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.
