Visit the maintenance site of the Hanyu 1 Bridge: Construction of more than 70 workers at the same time at the same time

Hubei Daily Client News (Correspondent Ye Benlin Quan Media Reporter Zhao Yiran Intern Lei Jingyi Chen Qiqi) On August 1st, on the first day of the closed construction of the Hanyu Bridge, the reporter came to the construction site of the first bridge of Hanjiang. The workers are demolishing the paving layer of the bridge surface. The workers under the bridge climb the bottom of the bridge to the bottom of the bridge for the bottom of the bridge to repair the solid work.

Xiangyang No. 1 Bridge, as the first cross -river bridge in Xiangyang City, was opened to traffic on May 20, 1970. It has been operating safely for 52 years. The emergence of a bridge of the Hanjiang River ended the history of the people crossing the river on both sides of the Han River, and also made a significant contribution to the travel and urban economic development of Xiangyang citizens. This maintenance is the first two -way sealing bridge maintenance of the Hanyu Bridge Highway Bridge in 52 years.

It is understood that due to the long service time of the Hanjiang Bridge Highway and bridge, the original design of the original load, the increase in transportation, and the increase in heavy -duty vehicles, the continuous accumulation of the bridge damage, the irregular cracks of the bridge floor paving, which affects the driving of driving, affects driving. Comfortability; bridges and T -beam concrete aging to varying degrees, which reduces the bridge carrying capacity. After the testing company's testing, there were relatively serious structural diseases in the main bridge and leading bridge of the Xiangyang Hanjiang Bridge Highway. The bending capacity of the bridge was insufficient. The comprehensive assessment of the test was not qualified, and it was necessary to perform maintenance and reinforcement.

At three o'clock in the afternoon, wearing a helmet and wearing a reflective vest, Zeng Wenfeng, deputy manager of Wuhan Erhang Road Bridge Special Engineering Co., Ltd., Xiangyang Hanjiang Bridge Highway Bridge Maintenance and Reinforcement Engineering, is on the Hanyu Bridge. Work. Zeng Wenfeng introduced that in order to ensure the convenience of citizens' normal travel during the construction period, this construction adopts a partition parallel operation and flowing operations between the processes, and the four operating planes of the bridge, the bottom of the bridge, the left, and the right of the bridge are carried out at the same time. From the 1st, the work of bridge deck will continue for 50 days, and more than 70 workers will invest in solid work.

"The section of the bridge adopts the steel hybrid combined reinforcement process to increase the bending resistance. The dense and real concrete used by the bridge part of the bridge has the characteristics of strong liquidity, which can make the steel surface fits more densely to increase the stability; the main bridge part is reinforced with carbon fiber cloth, the quality of the carbon fiber cloth is small and the tensile resistance can reach the ten steel. More than times.

At present, the construction of the construction of the bridge deck is carried out. The upper structure construction is expected to be completed on September 20, and the overall construction will be completed on December 27.
