On September 28, 2025, the Huajiang Gorge Bridge was opened to traffic, spanning the Huajiang Grand Canyon, known as the "crack in the earth".
In 2021, the Party Committee of Guizhou Bridge Construction Group Co., Ltd. won the title of “National Advanced Grassroots Party Organization”. The party committee of the group insists that "wherever the project develops, the party organization will be built." The party branch of Lu'an Expressway LATJ-8 project was established in response to the situation. It has 7 party members with an average age of 30 years old.
The project is divided into 6 party member responsibility areas including the main tower construction site and mixing station, and 14 "party member pioneer posts" have been set up. The Party Member Vanguard Team, the Party Member Quality Supervision Team, and the Youth Commando Team were successively established.
The challenges are unprecedented. The 93 steel truss segments, with a total weight of 21,000 tons, need to be connected with high precision one by one at an altitude of more than 600 meters; the instantaneous wind force in the canyon can reach level 14, and the 215-ton steel beam swings like a pendulum in the strong wind.
"Communist members must stand up at critical moments." Wang Songyu, former deputy project manager and captain of the Youth Commando, led the team through repeated simulations and overcoming difficulties, and successfully developed a "smart cable hoisting system" - a high-definition camera plus Beidou system plus the Internet of Things, which automatically adjusts the hoisting path and posture to achieve precise control and one-click hoisting.
Liu Hao, chief engineer of the bridge, led his team to use the Doppler lidar wind measurement system to capture wind field data 24 hours a day and build a "bridge" to reconcile with the canyon wind. Li Ping'an, the former head of the No. 8 standard work area, has been keeping an eye on the wind every day for three years, checking wind farm data on his mobile phone at any time. In the most critical part of hoisting the steel truss beam, Li Ping'an followed the hoisting process every day. "I didn't dare to blink. There might be a problem if there was even a centimeter difference."
The branch organized party members to focus on cultivating and developing new productive forces and independently developed a number of world-first construction methods and techniques. Six technologies are the first in the country: lightweight forged-welded structural cable saddles, which improve mechanical properties by more than 30% and save 28.7% in steel consumption; smart cables The detection system implanted "neural perception" into the bridge; waste stone powder was used to replace 20% of the cement usage, saving 12.4% of the cost per cubic meter of concrete... During the construction of the bridge, the entire project team obtained a total of 17 invention patents and 4 utility model patent authorizations.
Standing on the bridge, Liu Hao remembered that the Jiangjie River Bridge that his mother participated in building when she was young was once the pride of Guizhou. Thirty years later, when she saw the world's tallest bridge built by her son, she sighed softly: "I didn't dare to think about it before."
A bridge, a group of people, a flag. Build the branch on the construction site and transform the organizational advantages into attack advantages - in every technological breakthrough and in the precise connection of every steel cable, the party flag is always flying high above the "cracks in the earth".
