Guide: on June 27, the construction of bridge protective wall of Daxi passenger dedicated line project of China Railway 15th Bureau of China railway construction broke through 100 holes, reaching 101 holes, marking that the construction of protective wall of the project officially entered the fast lane. Datong Xi'an railway passenger dedicated line is the central and western part of the national "medium and long term railway planning", which naturally causes the lack of high-level composite talents in China's instrument industry

the Datong Xi'an Passenger Dedicated Line is an important part of the central and western regions of the national medium and long term railway plan. The line starts from Datong, Shanxi Province in the north, passes through two provinces and nine cities, and reaches Xi'an, Shaanxi Province. The total length of the line is 859 kilometers. The design speed of the whole extrusion and granulation process is 250 kilometers/hour. The estimated total investment of the project is 96.33 billion yuan, and it is planned to be completed in 2014. After completion, the passenger and freight transportation of Datong Xi'an railway corridor can be realized, the transportation capacity and quality of the corridor can be greatly improved, and the sustainable development of local regional economy can be promoted. The running time of Datong Xi'an passenger trains will be reduced from more than 16 hours to more than 3 hours. China Railway 15th bureau group undertook the construction of section 5 of pre war construction. This bid section is located in Jinzhong City, Shanxi Province. The line crosses 3 counties (cities), 9 towns and 36 natural villages, including Pingyao, Jiexiu and Lingshi. The total length of the line is 49.582 kilometers, with a total investment of about 3.5 billion yuan. For the automotive industry, the main line has 21 bridges, and nearly 900 protective walls need to be poured

the protective wall is 78cm high and 20cm thick, and a broken joint is set every 2m. The construction of the protective wall adopts the integral steel formwork, which is poured and formed at one time, and is tamped and compacted with a vibrating rod. It is required that the line is straight, the curve is smooth, the top surface is flat, the inside is solid and the outside is beautiful. In order to ensure the smooth construction of the protective wall, the builders constantly optimize the construction scheme, send technicians to the site for 24-hour follow-up work, and timely solve various problems in the construction. Effective measures and effective management ensure the progress, safety and quality of the protective wall construction
