The bridge files

The total length of Jingyuan Jintan Yellow River Bridge is 1.089 kilometers. The main bridge is (100+168+100) meters low-pylon cable-stayed concrete cast-in-place continuous beam bridge, with a width of 36.5 meters and a two-way six-lane design. It is the bridge with the broadest beam surface among Bridges built in Gansu Province.

Since its construction, the bridge has received keen attention from all walks of life. Jingyuan County Party Committee and government set up a special working leading group to coordinate and promote the project construction throughout the whole process. Relevant departments and units cooperate closely; The local masses give full understanding and cooperation to the inconvenience brought by the construction. The construction unit overcame many difficulties, such as high technical difficulties, high technical requirements and difficulties in epidemic prevention and control, and worked hard and carefully to create a high-quality project, which gave a perfect answer to the people of Jingyuan.

The bed of the Yellow River in the construction area of the project is sandstone covered by thick cobblestone layer. The embedded force between steel sheet piles and sandstone strata for construction cofferdam is limited, and there is a risk of piping. In the construction process of cap, once the pipe surge occurs, it will not only affect the construction progress, but also endanger the life safety of construction workers. In view of the above problems, the Project Department broke through the routine, vigorously carried out scientific and technological research, and effectively solved the piping risk.

In addition, the project department technical personnel through hard, also solved the cut pile head progress is slow, continuous beam anchorage tooth size and rapid motion in vertical installation, single strands tensioning prestressed reinforcement when constantly back top and a clip of the low efficiency and so on many problems, a total of 1 invention patents, utility model patents seven, 1 item of China highway construction methods, etc.
