Railway Construction: the first domestic open type TBM
Recently, China's first large diameter full face tunnel boring machine (TBM) design review meeting and design liaison meeting supported by the National 863 plan were successfully held in Changsha. Railway construction heavy industry developed the first domestic open type TBM is another important milepost roadheader development industry in china.
Participate in the meeting of experts well-known domestic TBM design, construction, geological and other aspects of the problems, we design and manufacture of pine Jilin cited water supply project owners and railway construction group will open TBM for the exchange and discussion.
It is reported that the central city of Jilin province Songhua River water supply project is located in central Jilin Province, the water supply project scope for Changchun City, Siping City, Liaoyuan city and belongs to Jiutai, Dehui City, Nong'an County, 11 city, county, District of the city, and the water supply line near the town of 25. In order to ensure the safety, environmental protection and high efficiency of the project, the construction party decided to adopt the open type full face tunnel hard rock boring machine (TBM) after many arguments. The construction strictly after public bidding, that is the design and manufacture of railway construction heavy roadheader experience, relying on China railway Limited by Share Ltd, has successfully produced nearly 100 sets of roadheader, in 2013 2 to fill the coal mine successful offline mode TBM world is blank, the main draft shield machine /TBM national and industry standards in the research and development unit, key technology in the field of products has accumulated rich experience of independent innovation. After equal competition, the group succeeded in winning the TBM equipment of the two line of the main trunk line of the loose water supply project in the central city of Jilin province.
At present, China has not been a successful example of the development and production of open TBM, the group is the production of TBM will be the first domestic independent research and development, with independent intellectual property rights of the large diameter of open TBM, 12th Five-Year is also the national key support of high technology research and development program (863 Program) key projects.
The implementation of this project will fill the gap of the domestic roadheader, improve the level of China's major equipment manufacturing industry and the core competitiveness of major equipment. This is a big step forward in the localization of TBM; it is a big step forward for the domestic equipment manufacturing industry; it is also a great step forward in China's scientific research and manufacturing level to the world's top, and has very important historical significance and practical value.
