随着蒙华铁路MHTJ-16标段大中山隧道一号斜井小里程一声炮响,拉开了徐工集团三臂凿岩台车助力中铁上海工程局蒙华铁路大中山隧道机械化施工的新篇章。与传统的人工钻爆相比,使用凿岩台车施工,在提高效率、减少用工、改善环境、控制超欠挖和施工安全等方面均展现出显著优势。中铁上海工程局蒙华铁路MHTJ-16标全长44.86km,设计隧道14座,全长33.38 km,隧道占比超过74%,是目前中铁上海局在建隧道最多、单座隧道最长的铁路
With the MH18-MH16-M16 section of the Menghua-Huayuan Railway passing through the small-borehole at Dazhongshan Tunnel, a new chapter of mechanized construction of the tunnel of Dazhong Mountain in the Huayu Railway Bureau of China Railway Shanghai Engineering Bureau was opened with the help of a three-armed drill rig of XCMG . Compared with the traditional manual drilling, the use of rock drilling rig construction, in terms of efficiency, reduce labor, improve the environment, control of over-under-dig and construction safety have shown significant advantages. The MHTJ-16 project of China Railway Engineering Bureau in Shanghai covers a total length of 44.86km and has 14 tunnels with a total length of 33.38km and a tunnel proportion of over 74%. It is the railway currently under construction with the largest number of tunnels under construction in Shanghai Railway Bureau and the longest single-
