On April 4, 2019, Gansu Ruifeng Industrial Co., Ltd. hosted the acceptance meeting of 200 000 kN large tonnage friction pendulum isolation bearing developed and produced by Xinjin Tengzhong Road Construction Machinery Co., Ltd. in Chengdu. The meeting was attended by experts from Gansu Jingwei Construction Supervision Consulting Co., Ltd., Yellow River Survey Planning and Design Research Institute Co., Ltd., China Merchants Bureau Chongqing Transportation Research and Design Institute, and China Railway Bridge Bureau No. 7 Engineering Co., Ltd. and formed an acceptance group. The meeting heard a report on the design, manufacture, quality control and testing of the research and development unit, reviewed the relevant information, and carried out on-site inspection of the assembled support products.
The expert group agreed that the manufacturing process and inspection method of the bearing meet the requirements of relevant national and industrial standards and norms, the quality control system is sound, the inspection results of raw materials and processed products are complete, and the information provided for acceptance can truly reflect the manufacturing process of the whole bearing product. The force of each component of the 200 000 kN large tonnage friction pendulum isolation bearing is clear and definite. The performance index (conventional and isolation) of the bearing meets the design requirements of Jingyuan Jintan Yellow River Bridge. The expert group unanimously agreed to pass the acceptance test.
Jingyuan Jintan Yellow River Bridge Project in Gansu Province is located in the east of Jingyuan County, across the river is Myitan Township. It directly connects the Nanbin River Road, the Second East Ring Road and the Third Meitan Road on both sides of the Yellow River, and links the two sides of the Yellow River in the east of Jingyuan County. The main bridge structure is a low-tower cable-stayed bridge with pre-stressed concrete. The main girder is cast by hanging basket and cantilever. The main bridge is supported by 200 000 kN friction pendulum isolation bearing. The design reference period of the bridge structure is 100 years. The design service life of the bridge structure in this project is 100 years.
