2、Anti-floating anchor rod, thin underground continuous wall and anti-seepage wall in foundation treatment.

3、Pipe shed grouting and water stop grouting in tunnel engineering.

4、Construction of rock blasting holes for roads, mines, hydropower dams, etc.

5、Foundation reinforcement of various industrial and civil buildings such as railways, highways, bridges, roadbeds and dam foundations, water-blocking and sealing works, soft foundation treatment and geological disaster management.

6、Engineering application of bolt drilling, down-the-hole drilling, casing drilling and drill pipe casing composite drilling.

7、Single-tube and double-tube construction for general rotary jet engineering

Main feature

1、 Adopt full hydraulic power head transmission, infinitely variable speed, high drilling efficiency, low labor intensity.

2、  The hydraulic system of drilling rig is stable and reliable with long service life.

3、 The power head adopts hydraulic variable-speed mode with high and low grades, which can meet the requirements of various formations and different drilling techniques.

4. The drill has the function of crawler walking by itself, and the equipment can be moved easily and quickly.

5.  Equipped with a slewing mechanism, the hole can be manually transferred to the side of the track when needed.

6、 Compact structure, centralized operation, convenient and safe.

      7.The column can be stretched back and forth to meet the bolt construction requirements.

      8、Optional clamping device reduces labor intensity and operation time of loading and unloading drill pipe.

Drilling range：

1、Suitable for high-speed drilling in soil, sand and other strata, discharge mud and slag ;Three - wing bit and one - bit drilling,.

      2. It is suitable for drilling with air DTH hammer in rock stratum and broken stratum and discharging slag with air.
     3. It is suitable for drilling with hydraulic hammer at the bottom of holes in water-bearing strata such as broken layer and sand egg layer to discharge mud and slag.
      4. Drill pipe drilling and casing drilling.
     5. It can realize single pipe, double pipe, triple pipe rotary jet, swing jet, fixed jet and other rotary jet technology (customer optional).

7. It can be used as a complete set of equipment with the high-pressure grouting pump, mud mixer, rotary jet, rotary jet drill, flow deflector, nozzle, three-wing bit, one type bit and compound slice bit of our company.

8、It can be seamlessly connected with domestic and foreign drilling tools through reducer joint.
