A variety of railway extreme equipment products and technologies have been unveiled for the first time, helping to build another magical "Heaven Road"

On October 19, the Sichuan Tibet Railway extreme equipment research and development technology exchange meeting and new product conference kicked off in Zhengzhou, and each unit of China Railway High Tech Industry Co., Ltd. made its first public debut with a series of extreme equipment products and technologies. (reported by renmin.com on October 20) the whole line of the

Sichuan Tibet railway is 1742.39km, with a design speed of 200km / h and a speed limit of 160km / h for some sections, with a total investment of about 270 billion yuan. After its completion, the train ride from Chengdu to Lhasa will be reduced from 48 hours to about 13 hours, which is called another magical "Heaven Road" after the Qinghai Tibet railway. The scenery along the way is beautiful, which can be said to be a mass of people. Expectation. However, it is also recognized as "the most difficult railway construction" and "the most challenging railway project", known as "century project".

"if you want to do a good job, you must first sharpen your tools." At present, the requirements of science and technology and economic development for equipment have gradually developed from routine to extreme, especially the extreme of engineering construction, which inevitably requires engineering technology and equipment under extreme conditions. It is understood that the geological conditions along the Sichuan Tibet railway are complex. In addition to permafrost, avalanche, scattered, landslide, high earthquake area, geothermal, karst cave, underground river, rock burst and other complex geological conditions coexist. As the saying goes, "no diamond, no porcelain work". In such diverse and complex geological conditions, the construction of the world's most difficult railway projects requires extreme equipment with rich hard cores. A 6031 a 6031 big country project still needs big country heavy equipment. At this technical exchange meeting, more than 100 pieces of equipment and products were exhibited, including the "diamond" intelligent cantilevered roadheader for tunnel excavation, the "transformer" three arm rock drilling jumbo specialized in the hard rock of the tunnel, the "giant bridge erecting machine" for sea erecting, and more advanced tunnel TBM / pipe jacking underground engineering construction. Industrial intelligent system - shield cloud and so on. At the same time of overcoming engineering difficulties, Chinese Railway scientists are not only satisfied with this, but also use intelligent system to minimize the impact of construction on the surrounding environment and protect the vulnerable ecological environment in plateau area. Our country's development "requires both gold and silver mountains, and green waters and green mountains". We adhere to the basic national policy of harmonious coexistence of human beings and nature, conservation of resources and environmental protection. General Secretary Xi Jinping pointed out that the planning and construction of the Sichuan Tibet railway is of great and far-reaching significance to the country's long-term stability and the economic and social development of Tibet, and this event must be successfully carried out. Premier Li Keqiang pointed out that the Sichuan Tibet railway is not only the expectation of the Tibetan people, but also the aspiration of the whole nation. At present, China's development is unbalanced and the infrastructure construction in the central and western regions lags behind. We need to speed up to make up for this shortcoming, and gradually narrow the development gap between the eastern and central regions by expanding effective investment and accelerating the infrastructure construction in the central and western regions. It can be seen that the construction of Sichuan Tibet railway is of great economic, political and strategic significance. A 6031 a 6031 we are all in one mind, looking forward to the early completion of the Sichuan Tibet railway, and paying tribute to the workers fighting in the front line of China's infrastructure construction, as well as the scientists working day and night to develop technology for the construction project!
