Similar Product Information Feedback: On the construction site, there are two old machines, one MXL-150D drill machine and one other manufacturer's rotary drill machine, due to the difficulty of drilling in the geological conditions. Both teams abandoned their machines and left!

Construction Method:

1. Drilling Equipment: 8 pieces of 89 drill rods, 2 spiral drill rods, vortex drill bit, with an air compressor rated at 18 cubic feet per minute and 1.7 bar.

2. Construction Requirements:

* Anchor grouting angle: 30°

* Drill bit diameter: 200mm

* Drill depth: 18m

3. Method:

1. Connect two spiral drill rods, then attach the vortex drill bit (note: use low speed to avoid damaging the drill bit and ensure proper drainage);

2. Drill into the hole;

3. Open air, spiral drill rod drills in, oscillates back and forth to drain excess material (approximately 3-4 minutes);

4. Close air, attach two meters of 89 drill rods, open air and drill at a rate of approximately 1 minute 15 seconds;

5. Drainage, power head oscillates back and forth with intermittent stops (approximately 1 minute 15 seconds);

6. Attach 8 pieces of 89 drill rods for drilling and drainage, then complete the borehole;

7. Disassemble drill rod, place the drill rod's jaw interface between the upper and lower holding devices, tighten the devices, use a release mechanism to loosen the jaw; release the devices, lift approximately 50cm, re-tighten the devices, and open the jaw; use an electrical clamp to secure the lower interface, reverse rotation, and open the top jaw;

8. Drill rod disassembly complete. Machine relocated, anchor grouting begins.
