Thanks to CTOnews.com netizens for the clue delivery that you can change your name again! CTOnews.com, November 28, according to the Wuhan Railway, the first cast-in-place beam of the Han River Bridge, a control project of the Xi'an-Shiyan high-speed railway (referred to as the "West 10 High-speed Railway"), which is managed by Wujiuke Hubei Company and built by the 11th Bureau of China Railway, has been successfully poured, indicating that the line construction has entered a new stage.

The Hubei section of the Xi-10 high-speed railway is 86.36 kilometers long, with 98.85% of bridges and tunnels, and complex geological conditions. The Hanjiang River Bridge on the West Tenth High-speed Railway is 917.45 meters long, with a main span of 420m cable-stayed bridge across the river and two H-shaped towers with a height of 186.5 meters, which is the largest span cable-stayed bridge with beam-truss composite structure in the world. The cable-stayed bridge with beam-truss composite structure is a new type of bridge structure. The stiffening steel truss strengthens the stiffness of the beam, which can effectively control the additional deformation and creep deformation caused by temperature, and ensure the uniform stiffness distribution. to meet the requirements of track ride comfort and driving comfort during the running of high-speed trains.

The double-line cast-in-place simply supported box girder between pier 8 and platform 9 of Hanjiang Bridge for the first time is designed as a single box and single chamber section, with a single span beam length of 32.6 meters, and is poured with C50 high performance concrete. The project department adopts the support cast-in-place method for construction, and makes a comprehensive calculation of the bearing capacity of the foundation and the stability of the support in the early stage to ensure the stability of the temporary structure; during the concrete pouring, special personnel are set up to check the stability of the support, formwork, steel bar and embedded parts, to ensure that more than 350 cubic meters of concrete can be successfully molded.

CTOnews.com learned that the Xi-10 high-speed railway, which starts in Xi'an, Shaanxi Province, and finally arrives in Shiyan, Hubei Province, is designed to run at a speed of 350km / h and is scheduled to open in 2026. The total length of the Xishi high-speed railway line is 255.76 km, including 169.4 km in Shaanxi Province and 86.36 km in Hubei Province. There are seven stations in Xi'an East, Lantian, Shangluoxi, Shanyang, Manchuan pass, Yunxi and Shiyan East (existing operation). After it is completed and opened to traffic, a fast railway passenger passage will be formed between Xi'an and Wuhan.

The railway department said that the West 10 high-speed railway is an important part of the "eight vertical and eight horizontal" high-speed railway network in the country's medium-and long-term railway network planning, which is connected with the Han-ten high-speed railway. According to previous information, after the opening of the Xi'an-Shiyan high-speed railway, Xi'an to Shiyan will arrive within one hour, and the railway running time between Xi'an and Wuhan will be shortened from the current 5 hours to about 2.5 hours.
