NewsIn May, at the construction site of Huangpu Tunnel in Wumei section of Longlong High speed Railway in Meizhou, Guangdong, more than 50 builders from China Railway 25th Bureau seized the golden period of construction and promoted tunnel construction. The Huangpu Tunnel is located near the existing Zhanglong Line and has complex geological conditions, making it a key and difficult project for the section. After the completion of the Wumei section, the Longlong high-speed railway will be fully connected, becoming another high-speed railway channel connecting Fujian and Guangdong provinces.
Since the beginning of this year, the construction of railway projects in many parts of China has been progressing in an orderly manner. The reporter learned from China National Railway Group Co., Ltd. that from January to April this year, fixed assets investment in China's railways was 19.47 billion yuan, up 5.3% year on year, giving full play to the role of railway construction investment in stimulating the economy, and actively injecting new momentum into the sustained recovery of the economy.
In the first four months, the railway department focused on networking, network supplementation, and chain strengthening, optimized construction organization, strengthened safety and quality, ecological environment protection, and engineering investment control, and promoted high-quality and efficient railway engineering construction. Several railway construction projects made positive progress.
In Gansu, the Lanhe Railway, jointly built by China Railway 18th Bureau, completed the first hole box girder erection, marking the beginning of the full line box girder erection construction phase of the Lanhe Railway. In Tianjin, the construction of the "First Tunnel of the Thousand Mile Haihe High speed Railway" Jingu Haihe River Tunnel on the Jinwei High speed Railway, which was constructed by China Railway 14th Bureau, is progressing in an orderly manner. The shield machine with a maximum excavation diameter of 13.8 meters will penetrate the Haihe River and soon break through the 5000 meter excavation barrier. At the construction site of Yangjiahe Extra Large Bridge, the longest bridge on the Guizhou section of the Huangbai Railway in Guizhou, more than 200 builders from China Railway 23rd Bureau continue to carry out pier work on the bridge. The Yangjiahe Grand Bridge has a total length of 2428 meters and a highest pier height of 117 meters, making it a key and difficult project for the Huangbai Railway. In Jiangsu, the Tongtaiyang Extra Large Bridge, a controlled project of the Shanghai Chongqing Chengdu High speed Railway constructed by China Railway 11th Bureau, successfully closed its continuous beam across the Gumagan River and crossed major risk sources such as existing rivers. In Guangdong, the continuous beam of Shiyuan Super Large Bridge of Zhuzhou Zhaotong High speed Railway contracted by China Railway 16th Bureau was successfully closed, marking that the project has entered the bridge superstructure construction stage in an all-round way, and the construction of the Pearl River section of Zhuzhou Zhaotong High speed Railway has made important progress.
The head of the relevant department of China Railway Group stated that in the next step, China Railway Group will further promote railway planning and construction in a scientific and orderly manner, effectively improve investment efficiency, enhance the overall efficiency of the modern railway network, accelerate the construction of a modern railway infrastructure system, and ensure the timely completion of the railway "14th Five Year Plan" target tasks.
