1. The anchoring engineering of hydropower, mine, dam body and road subgrade is mainly based on skid-type light hydraulic anchor and drilling rig. The anchoring engineering of mine is mainly based on rock anchor, which requires high accuracy of hole formation, generally, it needs to be constructed on a scaffold of about ten meters high, so it is necessary to ensure that the rig is flexible and convenient to move on the scaffold, and also take into account the stability when the rig is perforated, and it is easy to be stably connected with the scaffold, air down-the-hole hammer is the most effective method for rock drilling.
2. Deep foundation pit anchor of high-rise buildings the same project is mainly crawler self-propelled full hydraulic anchor drilling rig because the foundation pit formation of urban buildings is mainly sand plus strap gravel, and generally drilling takes water as the power of slag removal and hole cleaning. Therefore, even if precipitation is carried out, the working site is relatively muddy. It is only suitable for crawler drilling rig operation.
3. Anchor Drilling machine supporting drilling tools develop towards the direction of the combination of local drilling tools and rock anchor drilling tools in the Three Gorges permanent ship lock dam anchor cable drilling project, the drilling rig with the best hole formation degree is a drilling rig developed by using the principle of drilling the soil anchor casing into the medium stability and wall protection, which is applied to the direction of the drill pipe in the drilling of rock anchor eye. Similarly, in order to solve the problems that the drilling efficiency of hydraulic driller is anchor eye lower than that of soil exploration and the casing drilling tools are seriously damaged.
4. Select pavement engineering machinery alarm basic parts
At present, anchor drilling machine imported from four-wheel chassis to internal combustion engine, hydraulic pump, hydraulic cylinder, hydraulic valve, control and operating system all refer to or adopt common basic parts of pavement engineering machinery, this is the direction that many domestic manufacturers should learn from and improve, and it is also a fast and effective way for domestic anchor drilling machine to reduce costs and improve reliability.
