The anchor drilling rig is mainly used for landslides in the prevention and control of various geological hazards on hydropower stations, railways and highway slopes, mountain slope management and dangerous rock mass anchoring projects. It is especially suitable for high slope rock mass anchoring and soil nailing projects. It is also suitable for construction of urban high-rise buildings, Airport, ground source heat pump well, roadbed reinforcement, deep foundation pit support of dam foundation of hydropower project, anti-floating anchor rod, foundation grouting reinforcement engineering hole, blasting hole of blasting project, high pressure rotary jet pile, tunnel pipe shed supporting hole Wait for a slight change in its power head to facilitate all-round construction.
DTH hammer conventional drilling, Casing pipe drilling, and twist drill rod drilling. It is suitable for various complex formations and different drilling methods.
1.The rotation speed can reach 170 rpm, the efficiency of using twist drill and soil layer is more impressive.
2.Energy saving and high efficiency; without the increase of power, the working efficiency is increased.
3.The speed increases and the torque increases to 7500NM.
4.Adopted new hydraulic system, the structure is simple, the layout is more reasonable, and the operation is more user-friendly.
5.Three rows of holes save working time and improve efficiency. It can be constructed in horizontal, vertical, elevation and negative angles to meet the needs of various construction processes.
6.Added automatic rotation function of the platform, which greatly reduces the labor intensity of workers during construction and improves the construction efficiency.
7.Equipped with diesel engine of double cylinder, is operated arbitrarily when there is no electricity, and it can be moved if you want to, so that it is more convenient to move the large foundation pit and enter and exit the warehouse. And the separate diesel engine can carry out high-pressure rotary spray construction.
1.Drilling with a three-wing drill bit and mud slag discharge. It is suitable for high-speed drilling of soil and other strata.
2.Air compressor DTH hammer drilling, air slag discharge. It is suitable for rock layer and broken layer construction.
3.The bottom of the hole is driven by a hydraulic hammer, and the mud is discharged. It is suitable for the construction of broken water layer, sandy egg layer and other strata with large water content.
4.Casing drilling.
5.Compound drilling of drill pipe and casing.
6.Single spray, double spray, triple spray, fixed spray, swing spray and other rotary spray and expanded head tracing technology.
