Railway Construction in Inner Mongolia Ordos tunnel boring machine
In January 4th, the year the first day of work, shield assembly plant Chinese railway construction group, a group of workers are busy assembling a diameter of 7.6 meters of the red disc onto the trailer, his face filled with joy and pride. The delivery of products for the development of railway construction group, with long distance and large coal inclined slope of completely independent intellectual property rights of the single shield TBM (tunnel boring machine).
The total length of 165 meters, a total weight of more than 1100 tons, need to install 30 trailers, transport 20 days to reach the "laws" of Inner Mongolia Ordos Shandong Bulianta coal mine.
According to reports, with the single shield TBM coal mine tunnel excavation, has a hole into a good quality, high safety, economy and environmental protection, small occupied space and many other advantages, the construction speed can be increased more than two times compared with the traditional method. The explosion-proof design of the key equipment system can ensure the safe and reliable construction of coal mine inclined shaft.
Just past 2014, the railway construction heavy industry group China overall in the construction machinery industry downturn contrarian flying, build track equipment, boring machine, special equipment industry three industry sector, the new contract amounted to 4 billion 200 million yuan, 3 billion 700 million yuan output value. Shield is widely used in Changsha, Beijing, Xi'an, Wuhan, Guangzhou and other cities subway engineering and railway, coal mine engineering, the domestic market share of the first.
The railway construction heavy chairman and general manager Liu Feixiang said: "in 2015, the railway construction heavy industry will increase new products and new technology development efforts to maintain steady growth momentum, to ensure that the new contract amount of 6 billion yuan." At the same time, enterprises also want to mergers and acquisitions, one to two domestic and foreign machinery and equipment manufacturing enterprises, in the consolidation of railway and subway two big market basis, to promote coal mining, water conservancy, municipal and overseas market.
The tunnel boring machine successfully delivered, and fully demonstrates the railway construction for regional market research and development, is a powerful weapon to expand the depth of the railway construction heavy marketing characteristic demand introduction, has a positive role in promoting the implementation of the strategic objectives of the group.
