IHIインフラ建設 List of Products and Services

"TRIAS" is a versatile assembly bridge that our company has uniquely developed, featuring excellent rapid construction capabilities and cost-effectiveness. As an emergency bridge, it can be safely installed in a short period at any site. Additionally, it can clear long spans and is easy to handle on-site, which shortens the construction process and, when considered together with the substructure, offers superior economic benefits. There are two types available: the "truss type," suitable for long spans and large machinery traffic, and the "plate girder type," which is suitable for shorter spans and is lightweight and economical. You can choose based on your intended use and requirements. 【Features】 ■ Abundant parts for versatile applications ■ Robust enough to accommodate large machinery ■ Economic benefits from shortened construction time ■ Quick response to various site conditions ■ Two types available: truss and plate girder *For more details, please refer to the PDF materials or feel free to contact us.

The "Transparent Bolt Eye Cap" is a rust prevention cap for bolts that has made the material of the conventional colored bolt rust prevention cap "Bolt Eye Cap" transparent, allowing visibility of the internal condition of the cap. It not only blocks oxygen and water, which are the causes of corrosion, to suppress corrosion but also enables visual confirmation of any deformation of the internal bolt. 【Features】 ■ Visualization of the interior through transparent material ■ Labor-saving inspection tasks due to interior visibility ■ Maintains the same performance as conventional products ■ Clear visibility of internal markings ■ Rust prevention for bolts through coating *For more details, please refer to the PDF document or feel free to contact us.

The "Water Drainage I-Drip" is an add-on type water drainage system for bridge deck slabs developed by our company, which has over 30 years of experience. It uses weather-resistant materials. Since it is an add-on, it ensures the cover of the rebar. Even if the I-Drip falls, it is made of a flexible material that poses minimal risk. 【Features】 ■ Ensures the cover of the rebar since it is an add-on ■ The flexibility of the material and elastic adhesive allow it to conform to surface irregularities ■ Utilizes weather-resistant materials ■ Made of a flexible material that poses minimal risk even if the I-Drip falls ■ Curved sides enhance the water drainage effect *For more details, please refer to the PDF document or feel free to contact us.

The "Tri-Up System" breaks the conventional concept of pushing hydraulic jacks upward and instead raises them by pushing them sideways, representing a groundbreaking method for bearing repair. It transforms the traditionally large-scale girder reinforcement, temporary facilities, and equipment into a compact, lightweight, safe, and easy-to-use lifting temporary support system. With numerous achievements in bearing maintenance and repair across the country, it has received significant recognition, especially for its contributions to the recovery work following the Great Hanshin-Awaji Earthquake in 1995. 【Features】 ■ Achieves a large lifting force with a small jack (the wedge effect amplifies hydraulic jack output by 3 to 4 times) ■ Allows for simultaneous lifting and temporary support, enabling safe operations ■ Easily applicable to misaligned girder connections and B.P. shoes ■ No need for special girder reinforcements or lifting brackets *For more details, please refer to the PDF materials or feel free to contact us.

The "Bolt Eye Cap" is a PVC cap that covers the bolt and nut parts, blocking oxygen and water that can cause corrosion, thereby suppressing corrosion and improving the durability of the bolt. It is a resin-filled type cap for rust prevention of bolts. Long-term exposure tests have been conducted in subtropical regions with strong ultraviolet rays. Depending on the installation environment, it has been confirmed that durability can be maintained for over 20 years. 【Features】 ■ Long-term rust prevention ■ Excellent cost-effectiveness ■ Wide variety of options ■ Easy installation *For more details, please download the PDF or feel free to contact us.

"Torque Up" is a jack system with a reduction gear that operates based on torque input. There is no risk of shock or sudden descent during jacking up, allowing for precise control of the lifting amount, and it is safe because the wedge does not retract even when the reaction force acts for a long time. Due to its safety, reliability, and high quality, it has garnered significant attention not only in civil engineering but also in rescue operations during disasters. 【Features】 ■ No hydraulic jack required ■ Capacity ranges from 75 tons to 1000 tons ■ Power source is a rechargeable driver (approximately 14V) ■ Height management for jacking up can be done in 0.1mm increments ■ Over-winding prevention operates beyond the reaction force, ensuring safety *For more details, please refer to the PDF document or feel free to contact us.
