The Huayudong Bridge’s original bridge had a main span. 150m Prestressed concrete truss-composite arch bridge, this bridge was... 1991 Year 3 The bridge was completed and opened to traffic last month. After years of operation, the overall strength and durability of the bridge structure have significantly deteriorated, leading it to be classified as a Class IV dangerous bridge. Currently, the bridge is subject to traffic control measures that limit vehicle loads, speeds, and heights. Since these traffic control measures were implemented, they have had a substantial impact on economic and social development, causing considerable inconvenience to residents along the route and various sectors of society. The demolition and reconstruction project for the Huayudong Bridge is urgently needed.
The newly built Huayudong Bridge features a main span. 180m A middle-supported basket-type steel tube concrete arch bridge with a total bridge length of... 269.6m , bridge width 12.5m Design load: Highway I Level, bidirectional 2 The roadway features an aesthetically pleasing bridge design that exudes a strong sense of spatial openness and harmoniously blends with the surrounding environment. The design incorporates several innovative measures, including avoiding the placement of bridge piers on the lake surface, enhancing drainage systems in the bridge deck, and installing sedimentation ponds. Additionally, during the demolition of the existing bridge, the newly constructed bridge’s pre-assembled arch ribs and stay cables were utilized to support the original structure, and the original bridge components were systematically dismantled. These approaches have minimized the project’s impact on the ecological environment of Hongfeng Lake and the drinking water source protection zone. Upon completion, this project will become another stunning scenic highlight not only for Guiyang City but also for the entire province of Guizhou.
The implementation of the demolition and reconstruction project of the Huayu Cave Bridge, on the one hand, is crucial for ensuring... G320 The project holds great significance for the transportation network and the safety of people’s lives and property. On the other hand, it will greatly accelerate the development of tourism in Hongfeng Lake Town and even the entire city of Qingzhen. After the project commences, our institute will actively cooperate with the construction contractor and wholeheartedly join in the construction of this project. We firmly believe that, with the care and support from leaders at all levels and our colleagues, and through the unremitting efforts of all participating construction units, we will surely turn this project into a high-quality, exemplary undertaking.
