Basic requirements for drilling performance of multifunctional anchoring drilling rig during drilling construction

Due to the vast territory of our country, there are significant differences in geological composition between the east, west, north, and south. So there are more performance requirements for anchor drilling machines, and this article will provide a systematic introduction to the performance of Tuoli anchor drilling machines.

Due to the vast territory of our country and the significant differences in geological composition between the east, west, north, and south, the geological conditions for anchoring construction are very complex. So there are some special requirements for the performance of anchor drilling rigs

In the mountainous areas of western and southeastern coastal regions of China, the mountains are high and the roads are dangerous, making transportation very inconvenient. Most of the equipment is constructed on manually built scaffolding, which poses great difficulties for the relocation and transportation of construction equipment; On the other hand, long-term mountain building movements have formed a large number of fractured strata, ancient landslides, and loose accumulation formations. During construction in these complex strata, drilling collapses, stuck drills, buried drills, and other accidents are prone to occur. Construction equipment and machinery are easily damaged under these complex loads. Therefore, multifunctional anchoring drilling rigs and equipment working under these complex geological conditions must have the following excellent performance:

1. The multifunctional anchoring drilling rig has a large torque output and a certain reserve coefficient, which can overcome the complex drilling load changes and stuck drilling phenomena inside the borehole.

2. It has a great ability to improve, and when complex phenomena such as falling blocks and collapses occur in the hole, strong lifting measures can be taken to prevent drilling accidents such as jamming and burying.

3. It has a large speed range and is suitable for meeting the needs of rotation speed changes when using different drilling methods under different soil and rock conditions.

4. Having a relatively long feed distance is important for improving drilling efficiency and adopting the pipe following drilling method. Generally, the feed distance should not be less than 1.8-2 meters.

5. It has the lightest weight and convenient disassembly and assembly performance. For anchoring construction in mountainous areas and high slopes with inconvenient transportation, it can not only reduce the labor intensity during equipment relocation, but also reduce auxiliary operation time, which is conducive to improving the overall construction efficiency.

6. The mechanization level of unscrewing drilling tools should be high, with the ability to mechanically unscrew drilling tools under high load conditions, reducing labor intensity.

7. The anchor drilling rig has good guiding performance, which is convenient for maintaining the straightness of the borehole.

8. The multifunctional anchoring drilling rig should have good process adaptability and be able to meet the needs of various drilling techniques such as conventional rotary drilling, pneumatic down the hole hammer drilling, spiral drilling, and pipe following drilling.

9. The multifunctional anchoring drilling rig and drilling tools have good reliability, can withstand the test of complex geological load changes, and are easy to maintain. Hydraulic motors, pumps, and directional control valves are the core components of drilling rigs. To ensure the reliability of the drilling rig, it is necessary to choose internationally and domestically renowned brand products.
