China has benefited a lot from entering the era of high-speed rail construction machinery

information on China's construction machinery

Guide: [6300 line of sight] on December 26, 2009, the Wuhan Guangzhou passenger dedicated line, the world's longest running high-speed railway, was regularly replaced. So far, the total mileage of China's high-speed railway has exceeded 2830 kilometers, ranking first in the world. Along with Jiaoji, Hefei Nanjing, Beijing Tianjin, Shitai, Hefei Wuhan, Ningbo Taizhou Wenzhou, Wenzhou

[6300 line of sight] on December 26, 2009, Wuhan Guangzhou passenger dedicated line, the world's longest operating high-speed railway, was officially put into operation. So far, the total mileage of China's high-speed railway has exceeded 2830 kilometers, ranking first in the world

with the smooth operation of 8 passenger dedicated railway lines including Jiaotong Jinan railway, Hefei Nanjing railway, Beijing Tianjin railway, Shijiazhuang Taiyuan railway, Hefei Wuhan railway, Ningbo Taizhou Wenzhou Railway, Wenzhou Fuzhou railway and Wuhan Guangzhou railway, Hubei, Hunan and Shanxi in the middle of the Bohai rim, Yangtze River Delta and Pearl River Delta have entered the first year of high-speed rail together

high speed railway will become one of the important investment themes

at present, China's high-speed railway technology has reached the world advanced level. The construction of "four vertical and four horizontal" high-speed railway trunk lines with a design speed of km/h has been fully started, and the construction of Metro and urban rail has been started. By 2012, the "four vertical and four horizontal" passenger dedicated lines will be put into operation. At that time, 13000 km of passenger dedicated lines and intercity railways will be put into operation, including 8000 km of speed per hour, There are 5000 kilometers per hour

wangzhiguo, Vice Minister of the Ministry of railways, said in August 2009 that the railway investment will reach 750billion yuan in 2011 and 700billion yuan in 2012. At that time, the total railway mileage will reach 110000 kilometers. According to China Construction machinery information, in early December 2009, the State Council approved the metro and intercity train projects involving 22 cities, with an investment scale of 882billion yuan. Therefore, China's high-speed rail investment has entered a leap forward stage. In, the average annual investment in China's railways reached more than 700billion yuan

relevant industries benefit from the Philippines

China's high-speed rail others: the era of zinc borate, calcium borate, sodium borate, barium metaborate and potassium titanate has come. Due to huge investment and concentrated construction cycle, it has a strong driving force to pull up the industrial chain. What specific industries will benefit from the construction of high-speed railway? There are 7 major links in terms of raw materials, parts, infrastructure, machinery, supporting facilities, operation and logistics and follow-up services, and the industry is complex

according to the analysts of China's construction machinery information industry, according to the order of industry benefits, the large-scale railway construction started since the current round of financial crisis will first benefit enterprises in railway infrastructure related fields (such as railway construction and construction machinery) and rail production enterprises. In different construction stages, the pulling effect on relevant industries is different. For example, piling equipment such as rotary drilling rig is in great demand in the civil engineering stage, while concrete machinery and bridge erection machinery are in great demand in the bridge erection stage... To sum up, the engineering machinery and special accessories required for the construction of high-speed railway according to the construction process are: Earthwork equipment, transportation equipment, rotary drilling rig, concrete machinery, bridge support, girder box equipment, bridge erection machine and other lifting equipment, paver CA mortar or track slab and other track bed paving equipment

development history of China's high-speed railway

2006~2007, China's railway implemented the sixth large speed increase, and China's railway system has mastered the complete set of technologies for the speed increase of the existing line of 200~250 km/h. The operating speed of EMU has reached 250 kilometers per hour

2005~2008, the Beijing Tianjin intercity high-speed railway system solved a series of technical problems restricting the speed, and the maximum operating speed was increased to 350 kilometers per hour. It marks that China has systematically mastered the complete set of high-speed railway technology with a speed of 350 kilometers per hour. Since then, China's high-speed railway technology has been squeezed into the world's advanced ranks, facing both the rising cost rigidity and the falling metal price

2008~2011, Wuhan Guangzhou, Zhengzhou Xi'an, Harbin Dalian and other passenger transfer lines continued to operate at a speed of 350 kilometers per hour. The construction of Wuhan Guangzhou passenger dedicated line has formed the standard of China's high-speed railway system. The highest operating speed of Beijing Shanghai high-speed railway is 380km/h

50% of the trains on the Wuhan Guangzhou special line run on viaducts, and there are countless bridges and bridges along the way. In the Shaoguan Huadu section alone, 39 large and medium-sized bridges and extra large bridges have been designed, while in the 55km Changsha section, there are 48 large and small bridges, including 12 extra large bridges with a length of more than 500 meters.
