The reasons why rotary drilling rig is widely used in engineering construction are as follows:
1. The construction speed of rotary drilling rig is faster than that of general drilling rig. Due to the structural characteristics of the pile, the impact method is not adopted, so it will be faster and more efficient than the general pile driver using the impact method.
2. The construction accuracy of rotary drilling rig is higher than that of general drilling rig. Due to the rotary excavation method adopted by the pile, in the case of fixed-point driving, the fixed-point driving accuracy of the pile will be higher than that of the general pile driver.
3. The construction noise of rotary drilling rig is lower than that of ordinary drilling rig. The noise of rotary drilling rig mainly comes from the engine, and other drilling rigs also include the noise of impacting rock.
4. The construction mud of rotary drilling rig is less than that of general drilling rig, which is more conducive to cost solution and environmental protection.
