Which Accessories Can Improve The Operation Efficiency of Second-hand Rotary Drilling RIGS for Soft Soil?

In soft soil operations, second-hand rotary drilling RIGS often encounter problems such as easy hole collapse, unstable drilling resistance, and difficulty in controlling hole quality. Reasonable upgrading or replacement of key components can effectively break through these bottlenecks and significantly improve operation efficiency and construction safety. The following is an analysis of the role of six core components in enhancing operational efficiency:

1.Wear-resistant drill bucket teeth: The soft soil layer contains a large amount of silt and clay. Ordinary drill bucket teeth are prone to wear, resulting in a decrease in cutting force. The selection of wear-resistant drill bucket teeth made of high-hardness alloy can reduce the frequency of wear, extend the duration of a single operation, and at the same time enhance the efficiency of grasping and cutting soft soil.

2. Anti-collapse drill pipe: The soft soil structure is loose, and the hole wall is prone to collapse during drilling. Equipped with anti-collapse drill pipes with a sealed structure, it can reduce mud leakage, maintain stable pressure inside the hole, avoid rework caused by hole collapse, and indirectly improve the overall operation progress.

3. High-efficiency mud pump: Soft soil conditions rely on mud for wall protection and sludge discharge. Low-efficiency mud pumps can easily lead to untimely sludge discharge and accumulation of sediment in the hole. Replacing the high-flow and high-pressure high-efficiency mud pump can accelerate the mud circulation speed, remove the drill cuttings in time and reduce the drilling resistance.

4. Reinforced drill pipe joints: The drill pipe joints of second-hand drilling RIGS are prone to wear or loosening due to long-term use. Repeated drilling in soft soil layers will accelerate the wear of the joints. The adoption of reinforced forged joints can enhance connection stability and reduce the downtime for maintenance caused by joint failures.

5. Intelligent torque control system: When drilling in soft soil, the torque fluctuates greatly, which can easily cause the drilling rig to overload or drill too slowly. Install an intelligent torque control system that can adjust the output torque in real time, match the resistance of soft soil layers, prevent equipment idling, and increase the drilling depth per unit time.

6. Anti-slip track plate: The bearing capacity of soft soil is low, and the drilling rig is prone to track slippage and subsidence. Replacing the wide anti-slip track plate can increase the contact area with the ground, reduce the ground pressure, decrease the slippage phenomenon, and ensure the stable movement and operation of the drilling rig on soft soil surfaces.

In conclusion, in light of the characteristics of soft soil, equipping second-hand rotary drilling RIGS with wear-resistant, anti-collapse and highly efficient core components can not only solve common problems during construction, but also extend the service life of the equipment, reduce operation and maintenance costs, and ultimately achieve a dual improvement in operation efficiency and construction quality. When choosing accessories, it is necessary to combine the model of the drilling rig with the actual working conditions, and give priority to products with strong adaptability and reliable quality to maximize the lifting effect of the accessories.
