brief introduction
The total length of the bridge from north to south is1146m, and the width is 28m. It is a cable-stayed bridge with single cable reinforced concrete inclined tower. The rhombic leaning tower inclines 60 degrees along the bridge direction, 63m above the bridge deck and10.5m below the bridge deck. The structure and mechanical properties are very complicated. At present, the bridge type and its structural form are the first in China, and the construction scale and grade are at the leading level in the whole province and northwest China.
Panlong Bridge connects Gaoxin No.5 Road in Baoji High-tech Development Zone in the south, the municipal administrative center in the north, and crosses Weihe River and Xibao expressway. The total length of the bridge from north to south is1146m, the bridge width is 28m, and the total investment of the project is 654.38+300 million yuan. Panlong Bridge is a cable-stayed bridge with single-side cable reinforced concrete inclined tower. The rhombic leaning tower inclines 60 degrees, which has complex structure, great construction risk and difficulty. In the engineering construction, the construction unit, the construction unit and the supervision unit repeatedly demonstrated the technical scheme, overcame the technical difficulties, carefully organized the construction, and completed the construction task with good quality and quantity.
Important significance
The completion and opening to traffic of Panlong Bridge is of great significance for promoting the connection and integration of roads between the old city and the new city, development zone, chencang district and Jintai District, Weibin District and the group, expanding the urban development space, implementing the urbanization-driven strategy, further improving the living environment and investment environment, and accelerating the pace and economic development of cities with a population of one million.
In recent years, the city has closely focused on the goal of taking the lead in building a modern metropolis in the west, based on Baoji's situation and geographical and geomorphological characteristics, put forward the strategy of vigorously expanding eastward and moving northward and unblocking road and bridge projects, continuously increased effective investment, and stepped up the construction of traffic networks, so that the city's traffic planning has been gradually improved, the traffic capacity of urban road networks has been significantly improved, and urban traffic construction has entered a new development stage.
The dike reinforcement project from Douzhong Road to Panlong Bridge in Baoji City is an important part of the Weihe River flood control project in Baoji City, and it is also a safety barrier for the administrative center of Baoji City. This project is organized and implemented by Baoji Water Conservancy Bureau. It starts from Douzhong Road in the west and reaches Daima Bridge in Weihe River in the east, with a total length of 2.9 kilometers. This project is designed according to the once-in-a-century flood standard, and the dike level is Grade I. The estimated total investment of the project is10.06 million yuan, and the planned construction period is 3 months. On the premise of ensuring the safety of urban flood control, this project fully considers the absolute safety of the administrative center in the downstream urban area and the present situation that the backwater slope of the dike is close to Xibao Expressway. Starting from the needs of green Baoji, harmonious Baoji and building a modern ecological garden city, the strip-shaped open space outside the dike and backwater slope is afforested, beautified and landscaped as a whole. The dike adopts trapezoidal compound section, with the designed dike top width of 8m, and is equipped with flood control and emergency rescue roads, leisure strolling sidewalks and green belts. The project construction will greatly promote the improvement of urban ecological environment and investment environment, build a sub-center of Guantian and build a harmonious new Baoji.
