内蒙古水利厅牧区机井总队,通过两年的试验,于1983年成功的组装了拖车式简井钻机。这种钻机适用于中、深筒井的开挖,效果良好。这种钻机,全部打井设备组装在一辆平板拖车上,各种工艺以机械化为主,每班有四人便可操作生产。钻凿一眼口径80厘米,深30—50米的水泥管筒井,只需7—8天的时间,成井直接费用,每米80—90元左右,具有拖带方便,工序简易,生产效率高,成本低,适应性强等特点。在人工开挖大口井困难,打深机井出水量又小的地区,使用这种钻机凿井更为理
The Inner Mongolia Water Conservancy Department pastoral machine well corps, through two years of testing, in 1983 the successful assembly of the trailer-type shaft drilling rig. This drilling rig is suitable for excavation of medium and deep shaft well with good effect. This drilling rig, all drilling equipment assembled in a flatbed trailer, all kinds of mechanized technology, each class has four people can operate production. Drilling an 80 cm diameter, 30-50 meters deep cement tube wells, just 7-8 days, a direct cost into the well, 80-90 yuan per meter or so, with towing convenience, simple process, high production efficiency and cost Low, adaptable and so on. In the artificial excavation of large wells difficult, deep wells drilled a small amount of water in the area, the use of such rig drilling more rational
