以青海张家庄黄土隧道因地质灾害结构受损抢险加固施工为例,针对衬砌拆除重建、衬砌套衬加固、仰拱加固、道床板拆除重建等主体工程抢险施工,通过强化机械设备配置,并采取“大流水+小平行”高效的施工组织模式,有效的加快了抢险施工进度,达到了快速施工的目的,尽快恢复线路运营,将损失减少到最小。
Taking the Zhangjiazhuang loess tunnel in Qinghai Province for example, because of the structural damage of geological disasters and its reinforcement, the construction of linings, lining lining reinforcement, inversion arch reinforcement and the demolition and reconstruction of the ballast were carried out. By strengthening the mechanical equipment configuration, “Large water + small parallel” efficient construction and organization mode, effectively speeding up the progress of rescue construction, to achieve the purpose of rapid construction, as soon as possible to restore line operations, the loss is reduced to a minimum.
