Cover for improving visibility of wire rope columns
Cover for wire rope support
This is a new buried type joint with excellent water-stopping function, durability and economy, targeting ultra-small spaces among concrete bridges.
Keep dry E (埋設型止水装置)
This is a new type of drain that has the function of draining the shoulder pavement headwater belt and draining the water between the pavement and the floor slab.
S&SD drain (舗装浸透水排水装置)
The plastic deformation of the slit steel pipe effectively absorbs the kinetic energy during a large-scale earthquake.
Energy absorption type Chain-type bridge prevention device
Prevents the invasion of small animals and improves the maintainability.
Skit screen (Screen for vertical drain)
Used to prevent water leakage from seams such as box culverts.
Elast drain (Soft PVC gutter)
Prevents flooding of the road by dropping submergence that occurs at a part with a gentle vertical gradient into the internal canal and guiding it to the connected catchment basin.
2-way drain (Drainage groove for road flooding)
It is a room temperature type low viscosity penetrable emulsion that can fill not only the surface of pavement but also deep cracks and prolong the life of existing pavements with strong adhesion.
LVO seal (Normal temperature low viscosity penetrable emulsion)
It can deal with all forms of post damage and leads to a reduction in traffic regulation time.
