第一讲.立并施工机械化设备立井机械化凿井设备很多,这里主要介绍凿岩钻架、大型抓岩机、混凝土喷射机以及一些辅助作业配套设备。1.凿岩钻架目前我国使用的凿岩钻架有环形钻架和伞形钻架两种。环形钻架的构造和主要技术特征见图1和表1。它可钻2～3米深的小直径炮孔,但钻眼作业人数(15～30人)较多、效率较低。
Lecture 1. Construction and mechanization equipment Vertical shaft mechanized shaft sinking equipment, here mainly introduced rock drill rig, large grasping machine, concrete jet and some auxiliary equipment. 1. Rock Drill Rig Currently used rock drill rig in our country has two kinds of annular drills and umbrella drills. The structure and main technical characteristics of the annular drill frame are shown in Figure 1 and Table 1. It can drill 2 to 3 meters deep small diameter hole, but the number of drilling operations (15 to 30) more low efficiency.
