In Ismailia Province, Egypt, the main structure of the old Suez Canal railway bridge reconstruction and upgrading project undertaken by Chinese enterprises has recently been completed. At present, the construction personnel are paying close attention to the completion to ensure the early delivery to Egypt. The project is undertaken by a consortium composed of Sichuan Road and Bridge under Shudao group and Sinoma International Chengdu building materials industrial design and Research Institute Co., Ltd. (hereinafter referred to as Chengdu building materials Institute). According to gou Yong, the project leader of Sichuan Road and Bridge Company, the old bridge is a single track railway double wing horizontal steel bridge, which will be upgraded to double track two-way traffic after the reconstruction. The reporter saw at the scene a few days ago that under the scorching sun, the construction personnel are speeding up the installation of ladders and walkways, repainting the whole bridge, and the rotating docking process of the wings on the East and west sides of the 340 meter long bridge is smooth and orderly. The Suez Canal is located at the crossroads of Europe, Asia and Africa, connecting the Red Sea and the Mediterranean Sea. It is one of the busiest trade channels for oil, refined fuel, grain and other goods between Asia and Europe. In recent years, with the in-depth docking of Egypt's "vision 2030" and "Suez Canal corridor" development strategies with the "the Belt and Road" initiative, Chinese enterprises have increasingly participated in the implementation of projects in Egypt. Hezhongjian, project manager of Chengdu Institute of building materials, said that the Suez Canal railway bridge connects Africa and Asia, which is of great significance in the joint construction of the "the Belt and Road" project between China and Egypt. After completion, it will effectively promote the construction of the Suez Canal corridor and the contacts between the two continents. According to Mohamed Ibrahim, the project manager of the Bridge Department of the National Railway Administration of Egypt, after the completion of the bridge, the only railway connection between the West Bank of the canal and the Sinai Peninsula will be restored, and the railway transportation channels with said East port and bilabid City, North Sinai province will be opened, so as to speed up the logistics of bulk goods and effectively promote the construction of the Suez Canal corridor. "The old bridge reconstruction project is extremely difficult. The bridge slewing transmission device, hydraulic latch device, railway locking device, digital control system, etc. all need to be redesigned and replaced according to the requirements of the new contract. The bridge truss needs to add and replace more than 3500 components, weighing more than 5000 tons. Installation and welding are facing challenges." Gou Yong said that in order to successfully complete the task, the project construction team of the joint venture has conducted many studies, demonstrations and detailed adjustments on the design and construction scheme, and organized the technical team to tackle key functional devices such as rotary transmission, hydraulic bolt and railway locking, so as to ensure that the rotary is stable and locked reliably, and smoothly disengage after passing the vehicle to restore the canal channel. "At first, there were many worries and doubts about whether the reconstruction of the old bridge could be successfully completed. However, after continuous research and research by the technical team, we overcame challenges one by one and finally completed the important phased tasks in the process of rejuvenating the old bridge." Gou Yong said that although the epidemic affected the progress of the project, the owners highly recognized the performance spirit of Chinese enterprises in the epidemic. In hezhongjian's opinion, Chinese standards are also recognized by the owners. "In the process of project design and implementation, we conducted a large number of optimization consultations at home and abroad, actively communicated with international design companies, and introduced Chinese standards and schemes, which not only saved a lot of construction costs, but also made the scheme safer and more operable. Finally, the scheme was recognized by all parties." He said. "I learned to use the total station, GPS, level and simple calculation, which were taught by my Chinese colleagues." Karim Mohammed, an Egyptian employee, said, "they are all excellent engineers and will always be my good friends." (Xinhua News Agency)
