As well as newly constructing and renovating domestic bridges and floodgates in response to facility obsolescence and the need to maintain social capital through inspection, diagnosis, significant modification and so on of these facilities, the need for which is set to intensify, we will join our affiliate, IHI Construction Service Co., Ltd., to redouble our efforts and fulfill the roles. As well as steel structures, we will also focus on providing products to achieve safe, secured and comfortable lives such as seismic isolation/vibration damping systems and so on for buildings. Furthermore, overseas, we would like to disseminate our design/production/construction technologies developed through the domestic bridge/gate business with wide global penetration, to boost the development of a global society. IHI Infrastructure Systems Co., Ltd., including its boards and employees, shall, in solidarity, ensure compliance and help develop local communities as a member of society in striving for safety and health, environmental management activities and so on.

However, this method requires an underwater typically adopted in constructing arches. Here, the bridge body is suspended roads, located with constrained conditions such as a lack of work space for setting method. bent for the erection of the side span, and this can have a substantial effect by hanger cables from a main cable fixed between pylons, meaning the up, insufficient capabilities of large cranes, or limited time for erection (e.g. one-night The Air Spinning Method is a method to erect cables, by spinning small 5 on the environment. deflection may constantly changes according to each step of erection, and erection.) mm dimension wires one by one. We use the low tension control method, We provide a solution to this problem by the "Balancing Erection Method", requiring the length of the hanger cables to be frequently adjusted. Erection work in such cases requires special techniques to transport girders to the correct in order to ensure quality and workability. Unlike other manufacturers, we where the main girder is erected from a tower, to both sides of the axis In traditional cases, the left and right sides of the bridge body shall be erection position, avoiding obstacles that may exist on the left, right, top or bottom. have experience in the erection of overseas suspension bridges using the direction, by using a "Diagonal Bent". This method does not require an constructed alternately; but by changing the erection sequence to complete Normally, heavy -duty carrier on both sides are connected by steel bars to fix their interval. AS method. Through long experience, we have developed and established underwater bent. Although this may look like some kind of balancing toy, and one side first, improved method can shorten the moving distance of the Now, by using a developed sequence to control each vehicle positions, the vehicle know-how on the AS method, including quality control, high-speed erection, you may think it is unstable, actually good stability is secured by applying our workers and minimize the adjustment work of hanger cables by preload. motions can be changed by keeping fixed distance between each carriers. adaptation to longer span bridges, and improved AS erection machineries advanced position control technologies. This erection method is stable even Consequently, the relative position of the carriers can be independently adjusted for pitch which enable 24 hours seamless operation. during an earthquake or typhoon. and roll, which has expanded the feasible scope of erection work in the case that the width of the transport pathways are constrained.
