【摘要】 针对目前国内铁路、公路等边坡锚固工程中锚固钻孔作业费用高、费时、安全性差的问题,研制出一种了简单、可靠、适应性强锚固钻孔作业设备。该设备分为两部分:潜孔钻和机架。机架采用了一种特制的旱地雪橇式结构,潜孔钻通过铰座和支撑架与机架相连。该设备能在边坡上自由移动,省去了搭脚手架或使用大型的弊病。另外,为了适应新研制出来的这套设备制定了一套简单可行的施工方法,采用该套施工方法可以大大提高施工经济效益,而且安全可靠。更多还原

【Abstract】 In order to overcome the shortcomings of the traditional boring method on railway slop and road slop,a new construction boring method and correspond equipment are introduced.The boring machine consists of two parts: DTH drilling and dryland sled-type frame.The DTH drilling is installed on the dryland sled-type frame,so it can movie on the slop freely.Practice has proved that the machine can greatly reduce labor intensity and improve the efficiency of drilling holes on the slop.更多还原
