Reuse collapsed dirt
This method selects earth and gravel caused by heavy rain, mixes the earth and gravel into cement, and reuses it as INSEM material. This INSEM material is used to fill a double wall that consists of an upstream wall made of steel sheet piles and a downstream wall made of expanded metal. It delivers the same strength as a gravity dam.
Reinforcing civil engineering structures with steel material
Railway structures require higher quake resistance than other facilities. Seismic reinforcement improves quake resistance by placing steel material on the columns and walls of structures such as tunnels, subway viaducts, and bridges. This construction is feasible in narrow locations or even when there are obstructions around the site. It is highly strong and also cost-effective.
Performs reliable construction with flexibility backed up by advanced technology and know-how.
Constructs large structures with cutting-edge technology worthy of its nickname “Iron Shiohama.”
Builds safe and secure social infrastructure that allows people to live in harmony with nature and makes sustainable growth possible.
Metal-road method
Used for road widening on steep slopes
Also called a three-dimensional rigid-frame prefab plank bridge using hot-rolled H steel beams, this method is suitable for road widening on narrow, steep sloping ground, such as in coastal or mountainous areas. The pile secured to the supporting layer and the beams jointed perpendicular to the floor ensure high load bearing. Since this method requires less excavation and back-filling, the impact on the natural landscape or ecological environment is minimized.
