Fuxiake Specialty Quanzhou Bay Cross -sea Bridge Complete Railway No Railway Construction

Quanzhou Evening News · Quanzhou Tong Client July 4th (Quanzhou Evening News reporter Wu Lijiao Correspondent Zhou Xin Hu Xiaohu/Wen Chen Qituo/Figure) On July 4th, Fuxia Passenger Special Quanzhou Bay span from the China Communications Second Aviation Bureau The construction of the Hai Bridge has created favorable conditions for the subsequent rail paving and opening operations.

Liu Fuxing, executive deputy manager of the project of the Second Airlines Bureau of China Communications, introduced that the quality of no orbit construction is the key to ensuring the safe and stable operation of the train. This time, the construction of non -rail -free rail construction is the key control project of the entire line, the Quanzhou Bay cross -sea bridge, with a total length of about 20 kilometers, of which the construction length of the sea area is 9 kilometers. The CRTS Type Ⅰ dual -blockless orbit used as a concrete structure is required at one time, high accuracy, and strong operation.

For this reason, during construction, many difficulties in the face of difficulty transportation, many cross -construction operations, high technical standards, and high construction pressure, and the project department has developed and successfully applied to cross -sea multi -joint bridge CPIII fast networking technology 2. Wind -proof technology for the strong windy area, and the cross -sectional non -rail -shaped rail -shaped wire -shaped control construction technology of the cross -sea high -speed rail cable bridge. "By controlling raw materials and processes, we ensure the control of concrete strength and surface cracks. At the same time, strict control of construction accuracy and structural size, use automatic rail pillow pillow platforms, automatic rail paving machines and rail essence machinery and other intelligent construction equipment , Greatly improve the accuracy and quality of construction. "Said Weng Fangwen, chief worker of the Fuxia Railway Project of the Second Airlines Bureau of China Communications.
