Comparison of The Application Scenarios of Friction Resistance Rods And Mechanical Lock Rods

In the operation of rotary drilling RIGS, the selection of drill pipes is crucial to the success or failure of the construction. Friction rods and mechanical lock rods are two commonly used types. They each have their own characteristics and are suitable for different working conditions. Now let me tell you in detail about the differences in their application scenarios.

1. Soft soil layers: In soft soil layers such as silt and clay, the friction rod, with its own advantages of being lightweight and flexible to operate, can quickly drill and has a high drilling efficiency, without causing hole collapse due to excessive disturbance of the soil.

2. Shallow hole construction: When conducting drilling operations at a relatively shallow depth, the installation and disassembly of friction rods are convenient, without the need for complex locking operations. This enables the construction task to be completed quickly, resulting in higher construction efficiency.

3. High-precision hole-forming requirements: For projects with high hole-forming accuracy requirements, the machine lock rod, due to its strong rigidity and precise positioning, is less likely to shake during the drilling process, effectively ensuring the verticality of the hole and the accuracy of the hole diameter.

4. Deep hole construction: When deep holes need to be drilled, the advantages of the machine lock rod become prominent. It can provide sufficient drilling pressure and torque by locking each section one by one, ensuring the smooth progress of deep hole operations.

5. Hard strata: In hard strata such as rock layers and gravel, the machine lock rod can forcibly break hard rock and soil by relying on its strong rigidity and applied pressure, while the friction rod is prone to slipping and drilling difficulties in such strata.

6. Alternating construction in complex strata: When encountering complex working conditions with multiple strata alternating, the machine lock rod can better cope with stratum changes, stably drill from soft soil to hard rock, and has stronger adaptability.

To sum up, friction rods and mechanical lock rods each have their own "application areas" in the operation of rotary drilling RIGS. Choosing friction rods for soft soil and shallow hole operations is efficient and convenient. For construction in hard strata, deep holes and high-precision, complex strata, mechanical lock rods are more competent. Only by making reasonable choices based on the actual working conditions can the rotary drilling rig achieve its best performance and ensure the smooth progress of the project.
