The
roof bolter is mainly used for the sliding wave control engineering of railway, highway, water conservancy and hydropower facilities, the anchorage engineering of dangerous rock mass, the anchorage engineering of high slope rock mass, such as controlling the displacement of buildings, and also for the construction of deep foundation pit support and foundation reinforcement engineering hole, blasting engineering hole and tunnel pipe roof support hole. Good performance: compact structure, small size, light weight, flexible, suitable for high slope and scaffold work; The output torque of hydraulic power head is large, and the drilling ability is strong. The output speed of the power head is infinitely variable, and the drilling parameters can be selected according to different construction requirements and geological conditions to achieve the best drilling efficiency.
Anchor drilling machine form a complete set of drilling tools to the dialect tool combined with a rock anchor drilling tools in the direction of development in the three gorges permanent ship lock dam anchor drilling engineering, into the best drill hole bad degree is used in the soil anchor drill in stabilizing the porch and principle, and protecting the application in rock anchor drilling rod guide and developed at the drill stand, also, to solve the item hydraulic percussive drill drill a ground anchor hole efficiency is low, the casing drilling tool damage serious problems, are trying to study the air DTH hammer is extremely central bore hole casing drilling tools, and soil anchor drilling tools and a combination of rock anchor drilling tools.
Roof Bolter as an important mining, geotechnical engineering indispensable machinery, in recent years is also developing rapidly, many people in the industry are quite concerned about the technical development of the bolt drill, here mainly introduces the bolt hole drilling equipment technology status quo, hoping to pay attention to the industry to bring harvest.
