一、前言为了满足电站施工的导坑、上下河道的引水洞等小断面(6m~2～10m~2)隧道开挖的安全作业、快速掘进及高效率施工的要求,近年来采用梭车出碴的施工方法正在引人注目。日本豊平制钢公司生产梭车已具有二十多年的历史,积累了丰富的经验,所生产的梭车结构先进,安全可靠。二、梭车出碴及以往施工方法的概要采用梭车出碴的施工方法,可把一次爆破的所有碎碴快速装入梭车,运到弃碴场。缩短了下次支护到再次钻孔作业的时间,并可使操作人员马上从工作面退出。因此它是一种既能发挥最佳效率,又可有效利用空间,
I. Preface In order to meet the requirements of safe operation, rapid excavation and high-efficiency excavation of tunnels with small cross sections (6m ~ 2 ~ 10m ~ 2) such as pilot pit of power station construction and water diversion tunnels of upper and lower riverways, The construction method of ballast is attracting attention. Japan Hirakawa Steel Company has more than 20 years of shuttle shuttle production history, has accumulated rich experience, the shuttle shuttle produced by the advanced structure, safe and reliable. Second, the shuttle car ballast and the past construction methods Summary The shuttle car ballast construction method, all blasting ballast can be quickly loaded into shuttle shuttle, transported to the ballast dump site. Shorten the time from next support to drilling again, and allow the operator to exit from the work surface immediately. So it is a kind of can not only play the best efficiency, but also make effective use of space,
