备受关注的沪昆高铁预计今年年底全线通车,令人兴奋的是,沪昆高铁全线2264公里无缝钢轨达4528公里(双线),从头到尾似两条完整的钢轨一通到底,其中玉山至长沙段1254公里无缝钢轨由南昌铁路局鹰潭工务机械段向塘焊轨基地焊成,占全线总长的三分之一。这意味着我省成为全国11家权威焊轨基地之一。钢轨无缝化是通过先进的焊接工艺,将100米钢轨焊联成500米长钢轨,再使用特制的500米长轨运输车运送到线路上,在现场联焊成一根几百
It is exciting to note that the Shanghai-Kunming High-Speed Railway, which has attracted much attention, is opening to traffic by the end of this year. It is exciting that the 2,264 km seamless rails of Shanghai-Kunming High-Speed Rail reach 4,528 km (two lines) and two complete rails go through from the beginning to the end. To 1254 km of Changsha seamless rail seamless steel rail by the Nanchang Railway Bureau Yingtan mechanical welding section to the weld base, accounting for one-third of the total length of the entire line. This means that our province has become one of the 11 authoritative rail base. Seamless rail is through advanced welding technology, the 100-meter rail welded together into a 500-meter long rail, and then use a special 500-meter long rail transporter transported to the line at the scene into a few hundred joint
