Analysis And Comparison of Rotary Drilling RIGS with Impact Drills And Rotary Drilling RIGS

In the field of foundation construction, rotary drilling RIGS, impact drills and rotary drilling RIGS are all commonly used equipment, but each has its own characteristics and applicable scenarios. The following is an analysis and comparison of these three devices from multiple dimensions to help everyone better understand and choose.

1. In terms of hole-forming efficiency. The rotary drilling rig adopts rotary drilling, equipped with a powerful power head and an automatic telescopic drill pipe. It has a fast hole formation speed and can complete a large number of operations in a short time. Impact drills break rocks by repeatedly impacting the drill bit, and their efficiency is relatively low. The rotary drilling rig removes sludge through mud circulation, and its drilling speed is moderate. The speed will be slower in complex strata.

2. Different applicable strata. Rotary drilling RIGS are suitable for soft soil layers such as clay and sand, but their efficiency decreases in hard rock strata. Impact drills can deal with complex and hard strata such as pebble layers and hard rocks, and have strong crushing capacity. Rotary drilling RIGS are suitable for various strata, especially performing well in soft soil layers and medium-hard strata.

3. Comparison of hole formation quality. Rotary drilling RIGS have high hole-forming accuracy and relatively regular hole walls, but they are prone to hole collapse in loose strata. The wall of the hole formed by impact drilling is rough and there is a lot of sediment at the bottom of the hole, which requires secondary hole cleaning. The rotary drilling rig uses mud to protect the wall, ensuring stable hole quality, smooth hole walls and good control of sediment.

4. Differences in environmental performance. When the rotary drilling rig operates dry, there is no mud discharge and the pollution is small. Even when it operates wet, the amount of mud used is also relatively small. During the operation of impact drills, mud splashes frequently and there is a lot of noise, which has a significant impact on the environment. The mud circulation volume of the rotary drilling rig is large, and the treatment of waste mud is difficult, which is prone to cause environmental pollution.

5. Equipment Cost and Maintenance. Rotary drilling RIGS are expensive and require a large initial investment, but they have high construction efficiency and can reduce unit costs. However, they have high maintenance and upkeep requirements. The impact drill equipment has a low cost and simple maintenance, but the worn parts need to be replaced frequently. The equipment and maintenance costs of the rotary drilling rig are moderate, and the cost performance is relatively balanced.

6. In terms of operational convenience. The rotary drilling rig has a high degree of automation and is relatively easy to operate. It has high technical requirements for operators but a short training period. The operation of impact drills relies on manual experience and has a high labor intensity. The operation process of the rotary drilling rig is complex, requiring the cooperation of multiple people and having high demands on teamwork.

To sum up, rotary drilling RIGS, impact drills and rotary drilling RIGS each have their own advantages and disadvantages. Rotary drilling RIGS are highly efficient and environmentally friendly. The impact drill has a strong rock-breaking ability. The hole-making quality of the rotary drilling rig is stable. In actual engineering projects, based on factors such as stratum conditions, construction period requirements, environmental protection standards and cost budgets, appropriate equipment should be reasonably selected after comprehensive consideration to ensure the smooth progress of the project.
