On June 13th, the Xi'an Bridge Reconstruction Project was completed as scheduled, and it took 252 days of tense and fought. It is planned to be officially opened on the 19th. Xi'an Bridge is the most important node on the main road of transportation in the western region and the central urban area. It was built in the Japanese and pseudo -periodic period in the 1930s. In the test, Xi'an Bridge was identified as a Class D dangerous bridge, and the Changchun Municipal Party Committee and Municipal Government decided to implement the transformation of the bridge.

It is understood that the old bridge of Xi'an Bridge is a reinforced concrete beam bridge with a total length of 37m. The bridge is divided into three, across the Beijing -Kazakh Railway Line and Light Rail Line 3. After testing, it is an unqualified state. The transformation work is imminent. The main content of the reconstruction is to create a new 60 -meter -long steel truffle arch bridge, and the lanes on both sides of the bridge. Ma Hongfei, the person in charge of Xi'an Bridge Reconstruction Project of Changchun City Investment Infrastructure Construction Project, said.

At the beginning of the project construction, it was launched in accordance with a bridge demolition plan approved by the Shenyang Bureau of China Railway. However, there are several outstanding problems during the project promotion process: the railway lines conflict with the land of the green park shed reform project. The daily life of surrounding residents has a great impact. After coordinating the China Railway Shenyang Bureau Group Corporation, the original railway line dismantling plan was adjusted to the original bridge demolition plan. The new plan has canceled measures such as temporary railway stools and guided steel bridges, which not only shorten the long -term loss of railway transportation energy, but also comprehensively calculates the investment of nearly 60 million yuan, and the actual construction period has also been shortened from 3 years to 9 months.

In June 2021, the Xi'an Bridge was officially closed. After careful research and careful organization, the first beam was removed on July 8th. After 4 days a week, 64 beams of the railway "skylight time" per day, 64 beams Remove one by one and complete the entire bridge demolition task on August 31. On October 20, the steel box beam began to assemble on the spot, and the assembly was completed on November 8. The top push began on November 15. This is a link with the most technical difficulty and the highest safety risk in the entire reconstruction project. With the help of 8 groups of large power hydraulic equipment, 1,700 tons of steel giants steadily slide. December 10th, December 10th. The success of the day was successfully pushed. During the period, the road transformation of the east and west ends of the bridge was completed. Under various constraints such as "short skylight time and high safety level", Xi'an Bridge completed the expected construction task 15 days in advance, and achieved simple opening on December 31. Considering the asphalt pavement of the low -temperature environment in winter and affecting the performance, temporary paving is adopted. On April 28, 2022, on the basis of strict implementation of the construction site prevention and control management requirements, the project entered the field and resumed work. In early May, the auxiliary lanes on both sides were closed and the construction of temporary pavement was performed and treated at the grassroots level. On June 2, the formal pavement was completed and resumed. Construction and bridge lighting; on June 13, with the completion of the last telescopic joint pouring, it marks that the renovation project is completed. Due to frequent rainfall recently, in order to ensure the quality and safety of the project, the health period is properly extended. Japan is fully formally put into use.

A brand -new Xi'an Bridge is across the railway and light rails. As an important node of the main road network of the main urban area, it will create a more convenient transportation environment for the people of Chuncheng, helping Changchun's high -quality development.
