2007年对中国铁路建设来说将是不平凡的一年,备受关注的京津城际将于年底竣工,武广、石太、郑西等客运专线都将进入建设高峰期。连一度难产的京沪高铁也传来了“有望年内开工”的消息。人们的目光终于重新闪亮起来。由于高速铁路造价数倍于常规铁路,所以“十一五”期间铁路建设投资规模大幅增加,从2006年到2010年,建设17000km铁路新线。其中客运专线7000km,总投资规模为12500亿元人民币。客运专线建设资金的投入无疑为建设者们采购优质、高效的工程建设机械打足了底气。高性能、高质量的优秀国产设备成为铁路建设者的首选,20tm级的旋挖钻机,单机产量150m2/h以上的大型水泥砼拌和站,大吨位的压实机械、路拌、厂拌设备,450～900吨级的提梁机和架桥机成为施工中的关键设备。现在,让我们分别走进京津城际轨道工程、武广客运专线和即将开工的京沪客运专线工程,感受火热的高速铁路建设热潮。
2007 will be an extraordinary year for China’s railway construction. The much-anticipated Beijing-Tianjin inter-city will be completed by the end of this year. The passenger dedicated lines such as Wu Guang, Shi Tai and Zheng Xi will all enter the peak construction period. Even the Beijing-Shanghai high-speed railway, once dystocia, came the news that it is expected to start operation within the year. People’s eyes finally shine again. Since the construction cost of high-speed railway is several times that of conventional railway, the investment in railway construction during the “Eleventh Five-year Plan” has increased substantially. From 2006 to 2010, a new railway line of 17,000 km will be constructed. Including Passenger Dedicated Line 7000km, a total investment of 1,250 billion yuan. Passenger Dedicated Line construction funds undoubtedly builders for the builders to purchase high quality and efficient construction machinery play enough of the Midi. Excellent domestic equipment of high performance and high quality has become the first choice of railway constructors. The 20tm rotary drilling rig, the large cement concrete mixing station with a single output of over 150m2 / h, the large-tonnage compaction machinery, road mixing and plant mixing equipment, 450 ~ 900-ton beam crane and bridge machine to become the key construction equipment. Now, let us walk into the Beijing-Tianjin inter-city rail project, the Wuhan-Guangzhou passenger dedicated line and the upcoming Beijing-Shanghai Passenger Dedicated Line project to experience the hot craze of high-speed railway construction.
