Hangbuhe Bridge is located at the junction of Feixi section and Hangbuhe-Baishan section, about 650 meters away from the estuary of Hangbuhe River into Chaohu Lake. The total length of the bridge is 158 1m, the total length of the main bridge is 260m, the main span is 120m, the width is 24.5m, and it has four lanes in both directions. The bridge was built by the Third Construction Co., Ltd. of China Railway 10th Bureau Group. The reporter saw at the project site that the facade of the main tower of the Hangbuhe Bridge, which has been penetrated, is "herringbone" and the transverse direction of the bridge is "Y", like an advancing step. The upper part of the bridge tower is like an open arm, with a tall and straight shape and a combination of motion and static.
After the Hangbuhe Bridge is completed and opened to traffic, the tourist avenue around Chaohu Lake will run through the whole line, and it takes only 40 minutes to drive from Hefei Binhu to Chaohu City and Lujiang City. At the same time, as the traffic artery of Hefei, Lujiang, Zongyang and Tongling and their residents' travel and passenger and cargo transportation, its completion means that residents on both sides of the strait will bid farewell to the history of crossing the river completely.
"High, large and high" has become a difficult point in construction.
According to the person in charge of the project, Hangbuhe Bridge is a huge bridge in the inland river construction in China, and its characteristics of "high, large and high" have become the focus and difficulty in the construction.
It is understood that the main tower of Hangbuhe Bridge adopts steel-concrete composite structure. The steel tower is 82 meters high and the concrete part is 24 meters high. The tower height above the pile cap is106m, and the tower height is the highest bridge in Hefei. The excavation depth of its foundation construction is the largest and deepest, which brings great challenges to the project. In addition, due to the heavy weight of the steel tower, according to the original design and construction plan, the steel tower crane weighing about 240 tons should be installed at the height of 1 10 meter, and the hoisting weight and height are equivalent to those of Wuhan Yingwuzhou Yangtze River Bridge and Tongling Yangtze River Bridge under construction in China at that time, ranking among the best in China.
"If the bridge is built in this way on the big rivers and seas, the construction will be relatively simple, but it will not work in inland rivers, and large equipment will not be able to enter the market due to the influence of the waterway. Moreover, the original construction plan has a long construction period, and the main body will not be completed until the end of 20 15. Therefore, after several rounds of calculation and demonstration, the synchronous construction of tower and beam was finally chosen, and the main beam was synchronized with the main tower. Save a lot of time on the basis of ensuring safety. " The person in charge said that since the opening of Hangbuhe Bridge for two years, technical research and scientific research have yielded fruitful results, and five patents have been declared, and related construction methods and scientific and technological inventions are also being declared one after another. The project plans to declare "Huangshan Cup" after the completion acceptance.
