After two consecutive days of load test, all test parameters of Xiangjiang bridge on Zunyu expressway are within the scope of specification requirements, the data are normal and in good condition
.
This indicates that Zunyu Xiangjiang bridge can be put into use
.
According to reports, Xiangjiang bridge of Zunyu expressway, as one of the two super large bridges in the whole line, is an important control project of the whole line
.
The bridge type is a double tower double cable plane composite girder cable-stayed bridge, and the cable tower adopts a rhombic hollow thin-walled structure
.
The tower is 288 meters high, ranking seventh in the world, fourth in Asia and second in Guizhou
.
The expressway passes through Yuqing County, Meitan County, Weng’an county and Bozhou district
.
The implementation of the project is of great significance to accelerate the rapid development of the central Guizhou Economic Zone, open up the internal and external channels of Zunyi, break through the traffic bottleneck constraints as soon as possible, and accelerate the construction of a modern comprehensive transportation system
.
At the same time, it is also a key project of highway construction in Guizhou Province
.
The cable tower of Zunyu Xiangjiang bridge, which is constructed by China Railway Guangzhou Engineering Bureau Group Co., Ltd., was started in September 2018 and capped in September 2019
.
The overall construction index is 0.73m/day, reaching the domestic advanced level
.
A total of 97 beam sections are designed for the whole bridge, which are erected by cantilever assembly of full slewing frame beam crane
.
The closure of steel beam of the main bridge is completed on September 27, 2020
.
During the construction, the safety risks such as high-altitude operation and edge operation are overcome, and the safety risk zero accident is realized
.
On April 26, Guizhou quality and safety traffic engineering monitoring and testing center inspected Zunyu Xiangjiang bridge
.
In this test, 48 heavy trucks with a load of 35 tons were used for load test
.
The deflection of main tower, mode shape, longitudinal displacement of main girder, maximum positive and negative bending moment of main girder, finished cable force of stay cable, deck elevation and permanent observation point measurement of the bridge were tested
.
The load test finally verified the performance of the bridge, marking that Zunyu Xiangjiang bridge can be put into use, laying a solid foundation for the opening of Zunyu expressway
