Style

Chifeng Bridge is the only leaning cable-stayed bridge with double cable planes in China, and the two ancillary buildings of the leaning tower - the spherical building on the top of the tower and the base of the tower The boat-shaped building will also become a featured landscape. Yesterday, the leaning tower with an inclination of 63 degrees and a height of 64.923 meters and the spherical "hat" on the top of the tower were basically completed, and the overall scale of the Chifeng Bridge began to appear.

According to reports, the weight of the spherical building reaches 100 tons. In order to wear this "hat" firmly, the construction of the stay cable "hanging cable" connecting the top of the main tower and the bridge body is particularly critical. Chifeng Bridge requires 20 hanging ropes per day, each of which is composed of several steel strands. The thickest diameter reaches 800 mm, requiring 127 bundles of steel strands. To this end, construction workers used a variety of new techniques to put a spherical "hat" on the leaning tower. At the same time, the "big ship" at the bottom of the tower has also completed civil engineering and is undergoing glass decoration. It will be able to accommodate nearly 50 people after completion and will be open to the public as a tourist platform, with an elevator going directly to the top of the tower. In addition, the asphalt paving project of the Chifeng Bridge has also been completed, and guardrails on both sides of the bridge are being installed. After it is completed and opened to traffic, the bridge will connect Chifeng Road and Haihe West Road in Heping District to the west, and Li Gonglou Overpass and Haihe East Road in Hedong District to the east, which will effectively alleviate the traffic pressure in the Tianjin Station area.
