Major progress!The "Xiangjiang River Diamond" of Wangcheng Xianghuozhou Bridge completed the construction of Chengtai

At 4 pm on June 17th, with the last car's concrete pouring into the double wall steel coffin, the second floor of the No. 30 main tower of the key control engineering of the fragrant furnacezhou bridge, the pouring was successfully completed, and the "Xiangjiang Diamond" was officially officially completed. Enter the upper tower seat and the construction stage of the tower body.

It is understood that the main bridge of Xiangfuzhou Bridge is 2.8 kilometers long, which is a unique tower mixed beam for a 300 -meter -trapped beam. Among them, the No. 30 main tower is the key process of the entire project construction. The tower is 202 meters high. The tower is a diamond -type reinforced concrete Sota. It is currently the highest bridge tower under construction in the Xiangjiang River.

"The main tower of No. 30 is divided into pile foundation, Chengtai, Tower, and tower columns." According to the relevant person in charge of the district Chengfa Group, the main tower of the main tower in this pouring is 45 meters, 28.2 meters wide, and 6 thick 6, 6 thick The use of concrete is 7614 cubic meters. It uses the form of "4+2" to be divided into double -layer pouring. It is a large -volume bearing platform with large difficulty in construction, the highest technical requirements, and the most concrete consumables.

Due to the large amount of concrete in Chengtai, the project department arranged a total of 3 car pumps and more than 30 concrete mixers to ensure that the concrete supply was sufficient.

"During the pouring process of large -volume concrete, the cement should release a certain amount of heat during hydration. If the calories are too high, the temperature difference between the inside and outside of the concrete will increase, it is easy to produce cracks and affect the quality of the project." The third -party monitoring unit was commissioned to monitor the construction of large -volume concrete temperature control. By setting up temperature sensing elements in Chengtai concrete, dynamically grasped the real -time temperature of the concrete, and took cooling measures such as cooling water pipe water circulation during the rising heat of the concrete to effectively ensure the quality of the concrete, laid a good foundation for the subsequent construction of the bridge Essence

The reporter also learned that since the pouring of the first floor of Chengtai on June 2, under the overall scheduling of the coordination headquarters of the Xiangfuzhou Bridge, the district Chengfa Group organized various participating units to do the people, machines, and materials in all aspects of people, machines, and materials. Detailed arrangement arrangements are made. The project department of the Second Airlines Bureau of the CCCC carefully organized a combination of operators to configure a variety of large -scale machinery and equipment, and the two classes were uninterrupted in 24 hours. During the pouring process, the project leader and technical personnel conducted on -site command. The experimental personnel controlled the cooperation ratio and concrete pouring of the concrete, and finally completed the construction of the No. 30 main tower inheritance at high quality and efficiency.

At present, 463 pile foundations, 77 inheritance, 37 pillars, and 10 span -cash -sized box beams have been completed. The entire construction of the project is promoted in an orderly manner. It is expected that the main tower is out of water in mid -August 2022. At the end of December, the construction of the section of the main tower is completed.

After the Xianglangzhou Bridge is completed and opened to traffic, it will effectively connect the high -speed rail Xicheng, Wangcheng Economic Development Zone, Daze Lake, Moon Island, Dingzi Bay and other areas, and further promote the formation of "one river on both sides of the river and the Lianhe coordination of the Hedonghe West" urban development pattern. Help Wangcheng's high -quality economic and social development.
