On March 16, the first continuous rigidframe beam on the Hezhou side of the jinhai Bridge, the main bridge of the Jinhai Bridge built by China Railway Bridge Bureau, was successfully closed as the last load of concrete was slowly poured.The closure section of the road is right 69-70# pier, right 70-71# block 2 closure section pouring together, a single closure section of concrete volume of 25 cubic meters.The 66.5 m continuous beam on the hezhou side is 4×66.5 m continuous beam. The pouring sequence of the closure section is first side span and then middle span. The pier 38# (left and right width) is two interface piers of 4×66.5 m continuous beam.Hanging basket closure must be constructed at the same time to ensure the stability of continuous beam body on both sides.The crane Side of Jinhai Bridge currently focuses on the construction of continuous rigid frame beams. In addition to the continuous beams of 4×66.5 meters, there are also continuous rigid frame beams of 180 meters in span. 18 sets of hanging baskets have been put into use, and workers work day and night to ensure the construction progress of continuous rigid frame beams.Jinhai Intercity Railway Bridge project is a key project of Guangdong Province. It starts from Hengqin New Area of Zhuhai, crosses Modao Gate waterway of Xijiang River and ends at East Zhuhai Airport Road. It is a key control project of the second phase of Zhuhai Intercity Railway.The main span is 3×340 meters, and the bridge is 1369 meters long and 49.6 meters wide. There is a two-way intercity railway of 160 km/h in the middle, and a two-way six-lane highway of 100 km/h on both sides.It is the world’s first multi-tower cable-stayed bridge on the same floor for both highway and rail, and also the world’s widest cable-stayed bridge for both highway and rail.Source | yangcheng evening news · Yang cheng sent coordinating editor | Huang Tiean
