[0002] Currently, auger drilling rigs use data loggers fixed on the rig to store various data during the drilling process, such as the working parameters of the drill rod and drill bit. This data can provide support for ensuring construction quality, optimizing operations, industrial automation, and subsequent analysis.

[0116] In this embodiment, the preset threshold is a pre-set threshold, which includes a preset rotation speed threshold, a preset tilt angle threshold, a first preset pressure threshold, a preset real-time depth threshold, a preset volume value, and a second preset pressure value. The controller 120 outputs a drill bit rotation speed alarm signal when the drill bit rotation speed is greater than or equal to the preset rotation speed threshold; outputs a drill rod tilt angle abnormality alarm signal when the drill rod tilt angle is greater than or equal to the preset tilt angle threshold; outputs a drill bit and formation pressure abnormality alarm signal when the pressure value between the drill bit and the formation is greater than or equal to the first preset pressure threshold; and outputs a drill bit and formation pressure abnormality alarm signal when the real-time depth value of the borehole is greater than or equal to the preset real-time depth threshold. When the drilling depth threshold is reached, a real-time drilling depth abnormality alarm signal is output. When the volume of the poured concrete is greater than or equal to a preset volume value, a poured concrete volume abnormality alarm signal is output.

Specifically, if the drill bit rotation speed drops sharply, the pressure between the drill bit and the formation rises sharply, and the real-time borehole depth stagnates, it is determined that one or more of the following malfunctions have occurred: drill bit tooth wear, encountering hard rock or foreign objects, or insufficient hydraulic motor torque. If the drill rod inclination angle changes abruptly, the real-time borehole depth is abnormal, and the pressure at the concrete pouring location returns to zero, it is determined that one or more of the following malfunctions have occurred: drill rod fatigue fracture or torque exceeding limits. If the concrete volume increases abnormally and the pressure at the concrete pouring location fluctuates, and the real-time drilling depth rebounds, it is determined that one or more of the following faults have occurred: excessive drilling speed, failure to protect the loose strata in time. If the pressure at the concrete pouring location rises sharply and the volume of the poured concrete is insufficient, it is determined that one or more of the following faults have occurred: blockage of the concrete pouring conduit, damage to the sealing ring of the concrete pouring conduit. If the pressure between the drill bit and the strata is unstable, the drill bit speed fluctuates, and the drill rod tilt angle drifts, it is determined that one or more of the following faults have occurred: hydraulic oil contamination or leakage, pump / valve group failure. The fault determination results are then output to the display terminal 130, which receives and displays the fault determination results.

[0119] In this embodiment, the preset time period is a pre-set duration. The host computer 200 acquires and records the drill bit rotation speed, drill rod inclination angle, drill bit-to-surface pressure, borehole depth, poured concrete volume, and pressure at the concrete pouring location within the preset time period, based on the data stored in the data logger 110. A monitoring report (such as a document or table) is then output, allowing the user to understand the auger drilling rig's operation within the preset time period.

[0120] In this embodiment, the host computer 200 can train a fault analysis model (such as a neural network model) using a large amount of historical data on drill bit rotation speed, drill rod inclination angle, pressure between drill bit and formation, real-time borehole depth, volume of poured concrete, and pressure at the concrete pouring location. The trained fault analysis model is then used to input real-time data collected by various sensors into the fault analysis model when the auger rig malfunctions, resulting in a fault analysis result that is displayed. The host computer 200 can also train a fault prediction model (such as a neural network model) using a large amount of historical data on drill bit rotation speed, drill rod inclination angle, pressure between drill bit and formation, real-time borehole depth, volume of poured concrete, and pressure at the concrete pouring location. The trained fault prediction model is then input into the fault prediction model using real-time data collected by various sensors during auger rig operation, resulting in a fault prediction result that is displayed.
