The "Repair Lid (Slit Type)" is a renewal cover for existing gutters that enhances the functionality of sidewalks. It collects surface water through continuous slits and drains it into the gutter via drainage holes. The slits and drainage holes are designed to minimize sand clogging, ensuring reliable surface drainage compared to conventional covers. Additionally, the sidewalk area is unified and wide with a smooth pavement surface, creating a neat appearance, and the cover is covered by the pavement, reducing noise caused by cover rattling. 【Features】 ■ Barrier-free sidewalks ■ Excellent drainage performance ■ Improved sidewalk aesthetics ■ Noise reduction ■ Superior workability *For more details, please refer to the PDF document or feel free to contact us.

The "Armor Hume Segment" is a synthetic segment for sewers, composed of steel and reinforced concrete, featuring concrete compacted by centrifugal force inside a steel shell reinforced with rebar. It can be used not only for sewers but also for agricultural water, storage pipes, water supply, utility tunnels, and caverns. It is strong against internal water pressure and suitable for rainwater storage pipes. Additionally, it has high ductility and excellent durability during earthquakes, can reduce its outer diameter, and is particularly effective for construction in narrow spaces and sharp curves. 【Features】 - Strong against internal water pressure and suitable for rainwater storage pipes - Can reduce outer diameter, effective for construction in narrow spaces - Effective for construction in sharp curves - High ductility and excellent durability during earthquakes - Secondary lining can be omitted Certified material name for Category 2 by the Japan Sewer Association: "Synthetic Segment" *For more details, please refer to the PDF document or feel free to contact us.

"METAL" is a W-joint pipe made from a composite of high-strength centrifugally cast concrete and an outer shell pipe, resulting in a more robust thrust pipe. The important inner surface color and rubber rings for watertightness are protected from contact with the ground even when the joints are in a pulled-out state, ensuring watertightness at all times. With a large allowable pull-out length, it can accommodate various curved constructions. The external pressure strength is specified from Type 1 to Type 4, providing high external pressure strength. Additionally, the pipe body performance is specified at 0.2, 0.4, and 0.8 MPa, making it suitable for rainwater storage pipes and siphon pipes. [Features] - Two rubber rings attached to the pipe body - Large pull-out length - Abundant effective length - High external pressure strength - High internal pressure performance Certified equipment name under the Japan Sewage Works Association Type 2: "Concrete pipe with outer steel pipe" *For more details, please refer to the PDF document or feel free to contact us.

The "WIDE Safety Pipe Method" dissipates excess pore water pressure and drains it into the manhole. As a result, it is a method that suppresses the uplift of the manhole by reducing the frictional force around the manhole due to liquefaction. In the case of existing manholes, it does not require excavation work around the manhole since a collection pipe is installed from inside the manhole. Additionally, drainage into the manhole only occurs when an earthquake happens, preventing unnecessary water from flowing into the sewage system. 【Features】 ■ Jointly developed with the Japan Sewerage New Technology Promotion Organization ■ Applicable to both existing and newly constructed manholes ■ Minimizes traffic disruption ■ Performance remains unchanged even with repeated aftershocks *For more details, please download the PDF or feel free to contact us.
