Ensuring the verticality of the boreholes during deep foundation treatment is a complex process involving multiple technical and operational links.1. Overall structural design of the drilling rigThe overall structural design of the skid-steer auger has an important impact on the verticality of its boreholes. The base and sliding guide rails of the drilling rig are usually designed to be very stable to ensure that there is no excessive tilt or deviation during the drilling process. The power head and drill rod connection of the drilling rig usually adopt high-precision guide devices, which can effectively prevent the drill rod from deflecting during rotation.2. Guidance systemModern skid-steer auger machines are usually equipped with sophisticated guidance systems, such as laser guidance or electronic guidance systems. These systems can monitor the inclination and direction of the borehole in real time, and adjust the operation of the drilling rig through the control system to ensure that the borehole remains on the designed vertical path. The laser guidance system sets a laser transmitter on the top of the drilling rig, and the laser beam is projected vertically downward. The drill rod and drill bit of the drilling rig will be adjusted according to the position of the laser beam to ensure the verticality of the drilling.3. The structure of the drill rod and drill bitThe structural design of the drill rod and drill bit also has an important impact on the verticality of the drilling. The drill rod is usually made of high-strength and high-rigidity materials, which can maintain good linearity during the drilling process. The design of the drill bit is also very important. Usually, a center-guided drill bit is used to ensure that the drill bit always stays in the center of the drill rod during the drilling process to avoid deflection.4. Operator skillsThe skills and experience of the operator are crucial to the control of the verticality of the drilling. Experienced operators can adjust the drilling parameters in time according to the feedback information of the drilling rig (such as vibration, resistance, etc.) to avoid drilling deflection caused by improper operation. In addition, the operator can also adjust the position and drilling speed of the drilling rig in real time by monitoring the data of the guidance system to ensure the verticality of the drilling.5. Automatic adjustment function of the power headThe power head of a modern sliding auger machine is usually equipped with an automatic adjustment function, which can automatically adjust the angle and position of the drill rod according to the inclination during drilling. This automatic adjustment function can significantly improve the verticality of the borehole and reduce the error of manual operation.6. Control of drilling parametersDrilling parameters (such as drilling speed, drilling pressure, rotation speed, etc.) are also very important for the control of the verticality of the borehole. Unreasonable drilling parameters may cause the drill bit to deflect during drilling. Therefore, the operator needs to reasonably adjust the drilling parameters according to the geological conditions and drilling conditions to ensure the verticality of the borehole.7. The influence of geological conditionsThe influence of geological conditions on the verticality of the borehole cannot be ignored. For example, when drilling in soft soil layers, the drill bit is prone to deflection; when drilling in hard rock layers, the drill bit may be subject to excessive resistance, resulting in deflection of the borehole. Therefore, the operator needs to adjust the drilling strategy in time according to the changes in geological conditions to ensure the verticality of the borehole.8. Drilling rig stabilityThe skid-type auger machine needs to maintain good stability during operation to ensure the verticality of the borehole. The base and sliding guide rails of the drill rig need to be firmly fixed to the ground to avoid movement or tilting during drilling. In addition, the hydraulic system and power system of the drill rig also need to remain stable to avoid drilling deviation caused by system fluctuations.9. Monitoring and adjustment during drillingDuring the drilling process, the operator needs to monitor the verticality and direction of the borehole in real time. Modern skid-type auger machines are usually equipped with a real-time monitoring system that can display the inclination and direction of the borehole. The operator can adjust the position and drilling parameters of the drill rig in time according to the monitoring data to ensure the verticality of the borehole.10. Inspection and correction after drillingAfter the drilling is completed, the operator needs to check the verticality of the borehole. If the borehole is found to be deflected, correction techniques can be used, such as reverse drilling or using a correction drill bit to ensure that the verticality of the borehole meets the design requirements.The sliding auger machine ensures the verticality of the borehole through a high-precision guidance system, advanced automatic adjustment function of the power head, reasonable drilling parameter control, and the experience and technology of the operator. At the same time, the structural design of the drilling rig, geological conditions, and real-time monitoring during the drilling process also play an important role in the control of the verticality of the borehole. Through these comprehensive measures, the sliding auger machine can achieve high-precision verticality control of the borehole in deep foundation treatment.
