Jet Grouting Drilling in One-Time GM-60A Anchoring Drilling Rig Processing
Ⅰ.Application
It can be applied to railway, highway, bridge, subgrade, dam foundation and other industrial and civil buildings for foundation reinforcement, water isolation and leakage prevention, soft foundation treatment and geological disaster management. The machine is fully functional and can complete various jet grouting, anchor and anchor cable constructions. It can also be equipped with DTH hammer and pipe drilling tools to complete casing drilling; a top-drive hydraulic impact power head can be equipped.
Ⅱ.Main features
1. Pitching luffing structure, wide operation range.
2. Adopting full hydraulic power head transmission, stepless speed change, high drilling efficiency and low labor intensity.
3. Wide luffing angle, suitable for various hole positions.
4. The main components of the hydraulic system of the rig adopt well-known brands, and the system is stable, reliable and has a long service life.
5. The power head adopts hydraulic transmission and high and low gears. It can be equipped with high torque or high speed power head according to customer needs, which can meet the requirements of different drilling methods, and realize the multi-purpose of one machine.
6. The machine has the function of self-propelled crawler, and the equipment is convenient to move.
7. The operation platform can be moved to the vicinity of the orifice, and there is no dead angle in operation.
8. Compact structure, centralized operation, convenient and safe.
9. The column can be retracted back and forth to meet the needs of anchor construction.
Ⅲ.Drilling rig construction scope
1. Suitable for high-speed drilling in soil, sand and other strata, mud and slag removal; Three - wing bit and one - bit drilling.
2. It is suitable for air DTH drilling and air slag discharge in rock stratum and broken stratum.
3. It is suitable for drilling with hydraulic hammer at the bottom of the hole in water-bearing stratum such as broken stratum and sand egg stratum, mud discharge.
4. Drill pipe drilling and casing drilling.
5. It can realize single pipe, double pipe, triple pipe jet grouting, swing jet grouting, fixed jet grouting and other jet grouting technology (customer optional).
