The "TB (Touch Bond) Method" is a seismic adhesive joint method that can follow various ground displacements such as Level 2 earthquake motions and permanent deformation, thanks to its high-elasticity adhesive at the joint. Even after displacement, it maintains water tightness equivalent to or greater than that of elastic sealing (0.1 MPa or more). The connection points at curves, cross-sectional changes, and existing structures achieve the same joint structure and performance as straight sections. 【Features】 ■ Followability ■ Water tightness ■ Continuity ■ Workability *For more details, please download the PDF or feel free to contact us.

• Earthquake-resistant construction method

The "Line Drainage Block" is a box-shaped gutter designed to eliminate puddles that obstruct road users, enhancing safety and comfort. With continuous water collection through surface drainage slits, it quickly removes rainwater from the road surface. It is suitable for addressing puddles on roads with a small longitudinal slope. 【Features】 ■ Can be used as a barrier-free measure for wheelchair users ■ The cross slope of the shoulder is uniform, improving safety for two-wheeled vehicles ■ Effective for addressing puddles in areas where drainage slopes are insufficient due to existing structures *For more details, please download the PDF or feel free to contact us.

• Gutters and U-shaped gutters

The "Multi-board (Retaining Wall) Method" is composed of piles and PCa panels (precast panels), and it is a method designed to support the earth pressure acting on the PCa panels with the piles. The standard spacing for pile installation is 4 meters, and to transfer the earth pressure from the PCa panels to the piles, the PCa panels are fixed to the front face of the piles using connecting fittings. This allows for a retaining structure that does not expose the piles, resulting in an aesthetically pleasing appearance. 【Effects】 ■ By combining H-shaped steel as the parent pile with PCa panels, the structure does not require a base slab, which reduces the excavation width, making it possible to construct in sites where securing excavation width is difficult. ■ Since a base slab is not required, this structure reduces the number of pile foundations, the amount of foundation concrete, and the volume of excavation, enabling cost reduction and shortening of construction time. *For more details, please download the PDF or feel free to contact us.
