The Shenzhen China corridor is a major national project in the 13th five year plan and a super project in Guangdong, Hong Kong and Macao Bay area. It will open up urban agglomerations on both sides of the Pearl River Estuary.
Among them, the submarine immersed tunnel will set a precedent in the world. Compared with the immersed tube tunnel of Hong Kong Zhuhai Macao Bridge, it is 1.2km long and two lanes wide.
The novel coronavirus pneumonia earlier this year has brought about a short time impact on the construction. However, since February 10th, the project has been organized scientifically and orderly in the sub division and division of labor. Now, the Shenzhen China channel has fully resumed work, and more than 8000 workers are fighting for the front line.
Offshore construction environment is bad, wind and rain, exposure are inevitable.
The strong ultraviolet rays made the builders' skin dark, and they sprinkled the sweat of struggle on the Lingdingyang.
Li mama, the elder sister of Yi nationality in Leshan, Sichuan Province, is a tower crane commander on the "big kite on the sea". She is the "eye" and "arm" of the tower crane driver, and accurately shouts to ensure the safety of the lifting operation.
Wang Dechang is a diver. In order to plug the cracks in the cofferdam of the pier, he needs to drill to a depth of 15 meters for two or three hours. The underwater operation tests his endurance.
Construction workers are in this marine living area every day, surrounded by boundless sea water, drinking water and fresh food materials, which are transported in by transportation ships.
In order to enrich the lives of the workers, the project construction unit has set up supermarkets, KTVs, cinemas and libraries. Although they are not large, they should have all of them.

"If you want to be rich, you should build roads first." if bridges are connected, roads will be connected, and roads will be connected to finance. After the Hong Kong Zhuhai Macao Bridge was opened to traffic, the Shenzhen China channel once again continued the glorious story of Guangdong bridge construction and tunnel construction. The span of Guangdong's bridges and tunnels not only witnesses the technological leaps of Guangdong and even China, but also promotes the process of reform and opening up. The leap forward of social and economic development in Guangdong is inseparable from the hard work of workers behind every super project.
Praise the great country project! Salute the craftsmen of great powers!
