A new train line that makes cross-country trips faster has opened just in time for the end of the Mid-Autumn festival. The new high-speed train links Zhengzhou in central China’s Henan Province with Xuzhou in the eastern Jiangsu Province.
The 360-kilometer line has nine stations. It links two other major high-speed rail lines. They are the Beijing to Shanghai and Beijing to Guangzhou lines. The trains can cover 300 kilometers every hour. The 400-kilometer trip from Zhengzhou to Xuzhou will now take only 90 minutes. This is twice as fast as before. The completion of the line takes the total length of China’s high-speed rail network beyond the 20,000km mark, remaining to be the longest in the world.
China expects to add another 10,000km of high-speed rail by 2020, integrating about four-fifths of the country’s major cities into the network in the process. By 2025, its total length should be about 38,000 kilometers — just shy of the equator’s total length. The investment in infrastructure will continue to have a positive impact on economic growth, while the more extensive network will also create more jobs.
With the development of high-speed railway in China, the safety of tunnel construction is also more and more concerned by people. Self drilling injection bolts applied to tunneling support can combine drilling, grouting and anchoring together, which has a better anchoring effect than other anchoring products. Self drilling injection bolts have three functions as steel bar, drill rod and grouting pipe during the construction. So the use of self drilling injection bolts is safe, convenient, efficient and cost-saving. The actual cases in the past years have proved that the introduction and application of self drilling injection bolts has a very crucial influence on the geological anchoring industry in China.
