How to inspect, repair and reinforce a bridge without closing it or nearby roads? The bridge maintenance truck invented by WUDA JUCHENG STRUCTURE CO., LTD solves this global problem. Because of it, the company has obtained 1 international patent and 4 national invention patents.
The bridge maintenance truck is composed of four parts: "C-frame stands" "truss working platform", "6-winged helicopter" and "truck crane". It temporarily occupies the road during low traffic periods, using truck crane to assemble the C-frame stands and truss working platform. Then, an RC helicopter carries the rope to cross the bottom of the bridge. Then C-frame stands and ballast are installed, and the hanging baskets cross the bottom of the bridge to connect with the hook of C-frame stands. Then the ballast is removed and the hanging basket is lifted. Then an access ladder is installed so that the workers could work in the hanging basket. After maintenance, the truck crane can leave the site and make way for traffic.
All the work is conducted on the truss working platform under the bridge. As the truss moves forward, workers can comprehensively detect and reinforce the bottom of the bridge. When encountering the lamppost or stayed cable, the truck can avoid them by operating three retractable arms and continue its job.
Wang Mengshu, Member of Chinese Academy of Engineering, said after the visit: It is a great achievement. It has brought a revolutionary change to bridge maintenance. "The bridge maintenance truck is a pioneer product of China as well as the world. It is an achievement that lives up to the reputation of Wuhan University, and is the fruit of the integration of science, research and industry." Qin Shunquan and Gao Zongyu, Member of Chinese Academy of Engineering and survey design master of Bridge Institute also spoke highly of it after viewing the truck's operation.
In the past, when using traditional bridge maintenance trucks, bridges need to be closed or the roads need to be restricted, which seriously impacts the road traffic. The bridge maintenance truck developed by WUDA JUCHENG STRUCTURE solves this problem, and it is bound to enjoy huge market potential.
WUDA JUCHENG STRUCTURE has studied on the problem for ten years and has made a significant breakthrough in recent years. In 2009, the company invented the C-frame stands. It realized construction in 30 high-risk bridges of Three Gorges roads without closing the bridges. Thus, the C-frame stands have been rated by Three Gorges Corp. as the Model Working Platform. In 2012, the company has successfully carried out detection for the cable-stayed bridges of Second Wuhan Yangtze River Bridge, and has obtained a national invention patent. In 2013, the company developed the first commercial bridge maintenance truck for unclosed roads, and has applied for international patents for inventions.
