The "bicycle-friendly gutter" is an optimal slit gutter for bicycle path development in accordance with the "Guidelines for Creating a Safe and Comfortable Bicycle Use Environment" presented by the Ministry of Land, Infrastructure, Transport and Tourism. The exposed width of the gutter is extremely narrow at 90mm, allowing for a wider paved area. Bicycles can travel on the asphalt pavement, making it safer compared to typical L-shaped street gutters (with an exposed width of 500mm and a cross slope of 6%). Additionally, like our "urban-type gutter," it can continuously collect water through the slits, eliminating the need for expensive grating. In terms of management, the gutter's cross-section is oval, which increases the flow velocity during low flow conditions, preventing sediment accumulation and reducing cleaning costs. We have posted a video of the bicycle-friendly gutter on the construction technology and method video site of Kentsu Shimbun. By watching it, you can earn CPDS/CPD credits. https://cpds.kentsu.co.jp/technology/detail?id=115 *For more details, please refer to the PDF materials or feel free to contact us.

The "Tunnel Wall" is a wall for monitoring personnel within tunnels, developed by incorporating the high quality, beauty, and speed of precast concrete with the flexibility of cast-in-place concrete. It can be constructed at about one-fourth the cost compared to cast-in-place monitoring personnel corridors (approximately 1,000m), and with the addition of height adjustment features, it improves workability compared to conventional precast products. Additionally, the work yard required for installation is about 100m, allowing one lane to be used as a traffic lane. Since it can be opened up from where construction has been completed while moving, efficient work can be done in a limited space. This achieves significant cost reduction and results in a high-quality, stable, and beautiful finish. 【Features】 ■ Shortened construction period ■ Minimal workspace and efficient operations ■ Adjustable bottom plate length while securing management burial space ■ Height adjustment feature improves workability ■ Beautiful finish *For more details, please refer to the PDF materials or feel free to contact us.

The "Urban Type Street Drain JS-150" is a small cross-section drainage block used as a replacement for L-shaped street drains. By continuously collecting water through the slits, it narrows the apron width and provides a wider space for bicycle traffic. The slit width is 15mm, allowing for safe passage of road bikes. The hydraulically efficient oval cross-section eliminates the need for cleaning inside the pipe. Furthermore, the boundary blocks use JIS type, making it easy to change, replace, or repair, and it is also possible to install them while leaving existing boundary blocks in place. 【Features】 ■ No step in the riding space ■ Safe 15mm slit for road bikes ■ Complies with the "Guidelines for Creating a Safe and Comfortable Bicycle Use Environment" ■ Continuous slit drainage that prevents puddles ■ Anti-slip processing for safety even on rainy days ■ Lower cost due to wider spacing between catch basins compared to L-shaped street drains *For more details, please refer to the PDF document or feel free to contact us.

"LOCK+LOAD" is a simple reinforced soil wall construction method that pursues beauty, speed, strength, and cost-effectiveness. The soft rock surface provides a sense of tranquility and blends into the landscape. Additionally, by focusing on lightweight design and shortening construction time, it achieves overwhelming economic efficiency. Even on slopes that are difficult to access with machinery due to erosion from rain, it can be quickly and beautifully utilized as a retaining wall using only manual labor. 【Features】 ■ No heavy machinery required ■ Cost reduction possible ■ Economical and excellent workability ■ No need for slope line regulations ■ Can be operated in narrow spaces *For more details, please refer to the PDF materials or feel free to contact us.

The "EVERGREEN WALL SYSTEM" is a nature restoration-type greening method that aims to restore the natural environment that was once there. The Evergreen retaining wall can accommodate not only shrubs but also medium-sized trees, absorbing a significant amount of CO2. Additionally, the blocks are large, with a length of 5 meters, which enhances workability and allows for a reduction in construction time. 【Features】 ■ Trees thrive without management ■ Achieves height and steep slopes ■ Can be stacked up to 15 meters with cut earth ■ Extremely excellent workability ■ Shortened construction period *For more details, please refer to the PDF materials or feel free to contact us.

This product is a trench specifically designed for tunnels, conceived with the needs within tunnels in mind. The construction employs the "Perfect Joint Method," which utilizes the principle of leverage for one-touch installation. Additionally, various pipes and equipment, such as communication cables and water supply mains, are buried in the tunnel passage. The shape has been designed to ensure sufficient space for this burial. 【Features】 ■ Registered with the Ministry of Land, Infrastructure, Transport and Tourism's New Technology Information System (NETIS) (CB-010015A) ■ Secures pipeline space ■ Achieved a construction record of 150 meters per day ■ Consideration for paving machinery ■ Enhanced accessories for emergency parking areas and more *For more details, please refer to the PDF materials or feel free to contact us.

The "Urban-Type Trench Shape-Up Slit" is a slit trench born from a commitment to water flow, as well as the pursuit of strength and cost-effectiveness. The slim design of the surface and the continuous slits create a sharp beauty along both sides of the road. Additionally, because water can be collected continuously through the slits, expensive grating is not necessary. This allows for significant cost reduction compared to traditional trenches. 【Features】 ■ Slim design that creates beautiful streetscapes ■ Cost reduction ■ Good water flow ■ Excellent drainage capability ■ Quick installation *For more details, please refer to the PDF document or feel free to contact us.
