Anchoring drilling rig is mainly used for landslide and dangerous rock anchoring engineering in the prevention and control of various geological disasters in hydropower stations, railways and highway slopes, especially for high slope rock anchoring engineering, and also for the construction of urban deep foundation pit support, anti floating anchor rod and foundation grouting reinforcement engineering holes, blasting holes of blasting engineering, high-pressure rotary jet grouting piles, tunnel pipe shed support holes, etc.
| Rock drill is a tool for directly mining stone. It drills holes in the rock layers so that explosives can be put into them to blast the rocks, thus completing the quarrying of stones or other stonework projects. In addition, the rock drill can also be used as a destructor to break hard layers such as concrete. According to its power source, rock drills can be divided into four categories: pneumatic rock drill, internal combustion rock drill, electric rock drill and hydraulic rock drill. Its power head can be slightly changed to facilitate all-round construction. Main drilling methods: conventional down the hole hammer drilling, pipe drilling and spiral drilling. In the drilling practice of various complex formations and different drilling methods, its excellent drilling performance has been recognized by the majority of construction units and peers. |
It has good performance: compact structure, small volume, light weight, flexibility, and can be used to work on high slopes and scaffolds; The output torque of the hydraulic power head is large, the drilling capacity is strong, and the use range of the drill is wide; The output speed of the power head is infinitely variable, and the drilling parameters can be selected independently according to different construction requirements and geological conditions to achieve the best drilling efficiency. Therefore, no matter what type of anchoring drilling rig, the hydraulic transmission system is an important part of the anchoring drilling rig. If the maintenance is improper, various failures will occur, which will seriously affect the normal operation of the equipment. Therefore, great attention should be paid to the maintenance of the hydraulic system. |

| The supporting drilling tools of anchor drilling rigs are developing towards the combination of vernacular drilling tools and rock anchor drilling tools. In the anchor cable drilling project of the dam body of the Three Gorges Permanent Shiplock, the drilling rig with the best hole forming granularity is the drilling tool developed by using the principle of stabilizing the soil anchor casing and wall protection, and applying it to the direction of the drill pipe in rock anchor hole drilling. Similarly, in order to solve the problems of low drilling efficiency of hydraulic percussion drilling rigs in soil anchor hole exploration and serious damage of casing drilling tools, The air DTH hammer centering reaming casing drilling tool being tested and researched is another combination of soil anchor drilling tool and rock anchor drilling tool. |
