5月8日消息,由中铁二十二局集团四公司副总工程师林海剑等人研制开发的“隧道随机断面测量系统”新技术,经过在西南铁路东秦岭特长隧道、兰新铁路乌鞘岭特长隧道、宜万铁路齐岳山特长隧道等国内特长隧道2年多的使用,证明该项新技术具有很强的灵活性和适应性。该系统对隧道内放线测点、检测超欠挖值、偏移隧道中线值断面扫描、附属洞室放线以及洞外道路放样等几乎所有的测
May 8 news, the twenty-second Bureau of China Railway Group Corporation four deputy chief engineer Lin Haijian and others developed “tunnel random cross-section measurement system ” new technology, after the Southwest Railway East Qinling extra long tunnel, Lanxin Railway The more than 2 years of domestic long tunnels such as the sheathing tunnel, the QiYueShan tunnel of the YiWu railway have proved that this new technology has strong flexibility and adaptability. The system of measuring points in the tunnel line, detection of over-under-digging value, the offset tunnel median section cross-section scanning, ancillary cave-in and out of the cave and other road-setting out of almost all measurements
