△ The Xiangfuzhou Bridge project located in Wangcheng District is promoting construction in accordance with the node. After opening to traffic, another river crossing channel will be added to Changsha.

In the past few days, the construction of the fragrant furnacezhou bridge project in Wangcheng District has been promoted in an orderly manner in accordance with the nodes. After opening to traffic, another river crossing channel will be added to Changsha.

Construction of 4 teams to advance simultaneously

Recently, the reporter came to the construction site of the Hexi section of Xianghuozhou Bridge. The 285 builders of the Xiangfuzhou Bridge project of the China Communications Second Aviation Bureau were fighting at high temperatures here. They are responsible for the cable bridge, Hexi Diaogong and ramp bridge on the west side of the construction. Due to the complexity of the bridge construction process, the project divides the builders into 4 teams and advances simultaneously.

△ The builders are busy in the steel coffin

On the steel bridge, Zhao Gangshun, who was in his 50s, was working with his partner Zhao Liping. One was responsible for the command and scheduling of the car crane, and one person cut the scissors and other in the hanging basket. Both are welders and come from Henan. Because they work on the river surface, the two must wear life jackets. Even if the project department has recently replaced the foam -type life jacket into a smaller inflatable new life jacket, everyone is still sweating. Zhao Liping laughed: "Every day is wet every day, I haven't done it."

Not far away, the concrete pouring of the first tower of the No. 30 main tower has been successfully completed. Underwater operations are inseparable from an important "behemoth", which is the steel coffee wealth for water blocking to create a dry construction environment. In order to ensure the safe construction of the main pier, the steel soda weir is 1.6 meters thick. At present, the depth of operation is 15 meters, and the temperature reaches 50 degrees Celsius.

Add broken ice to the concrete to cool down

Since the start of the project, most of the 43 -year -old Han Peng has been busy in the steel coffin. He has been engaged in bridge construction for 23 years. He is currently the worker of the No. 30 pier woodworking class of Xiangfuzhou Bridge project. "I have been working in Wangcheng for two years, and I hope the bridge will be opened to traffic as soon as possible." Han Pei said.

The technical content of Xianghuozhou Bridge is high, and the requirements for design, construction and materials are very strict. Because the main tower is poured in the platform, the concrete requires uninterrupted construction and completed it at one time, which puts forward high requirements for the raw material preparation of the concrete. If the temperature of the concrete pouring is high, it is easy to affect the quality of the project. For this project, the temperature cannot exceed 28 ° C when the concrete is transported to the pouring site, otherwise the vehicle will be scrapped. As the temperature rises and the construction is facing huge challenges, Tian Zengxin, the technical director of the Ministry of Engineering, has tried many times to innovate the use of the method of adding crushed ice by the use ratio, which successfully cools the concrete.

"We adopt the two ends to catch up the middle interval to avoid the highest temperature period at noon. At the same time, the builders have prepared heatstroke materials such as mung bean porridge, watermelon, and Huoxiangzhengqi water." CCCC Second Aviation Bureau Xiangfuzhou Bridge Party Branch Secretary Pan Hu introduced. The project has completed the pile foundation, Chengtai, and Tower of the main tower of the Candid Bridge. The pile foundation of the Hexi Bridge and the Ringbridge has been basically completed. Construction has been fully entered a high -speed construction period. It is expected to have traffic conditions on December 31, 2023.

The Xianglangzhou Bridge is currently the largest span of the Dugta Calamity Bridge in Xiangjiang River. It is the first bridge designed according to the standard of the Class I channel. The main bridge is 3.24 kilometers long. After the bridge was completed, the development of Wangcheng District was accelerated into the development of Changsha's main urban area to form a urban development pattern of coordinating and linked to coordinate and coordinated by the two sides of the river.
