Zhongyuan Guanxi, a world-class project after the Hong Kong-Zhuhai-Macao Bridge

Underwater steel shell immersed pipe anticorrosion engineering of deep and medium passage is another world-class project in Zhongyuan Guanxi after Hongkong-Zhuhai-Macao Bridge. The project is located in the core region of the Pearl River Delta, with a total investment of about 44.69 billion yuan. The main project is about 24Km in length. The East Tunnel West Bridge project is the world's super-large "bridge, island, tunnel, underwater interchange" cluster project.

Among them, immersed tube tunnel is the world's first super-long, super-wide and super-deep submarine immersed tube tunnel, and it is also the first large-scale steel shell concrete structure project in the world. The E1 pipe section is the largest steel shell of immersed tunnel built in the world. It is 123.5 meters long, 46 meters wide, 10.6 meters high and weighs 8716 tons, which is equivalent to the discharge of a medium-sized aircraft carrier. At the beginning of the project, under the personal command of the general manager of the company, the relevant departments such as sales, technical cooperation and production cooperated with each other sincerely, overcome many difficulties, and finally successfully signed the paint supply contracts of the two tender sections of Shenzhen-Zhongdao Channel GK01 and GK02. At the same time, the company leaders personally supervised the construction of the pipe section, carefully organized and mobilized the backbone of various departments to actively participate in guiding the field work. The team of on-site technical service engineers also gave full play to the advantages of on-site technical support and cooperated closely with Guangzhou Shipping International Painting Department to ensure that the 100-year project had no slight leakage and successfully completed the sinking of deep passage. Anti-corrosion coating for steel shell of pipe E1 section. "Never forget your first heart and remember your mission". As always, COSCO Guanxi will continue to provide high-quality and first-class service for the anti-corrosion engineering of the immersed steel shell of deep and medium-sized corridors, so as to accumulate strength and add bricks for the development and construction of Guangdong, Hong Kong and Macao Bay Area.

In major national projects, Zhongyuan Guanxi people will spare no effort to contribute their own strength to the construction of the motherland!
