Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and in particular to a large-diameter drilling device for thick residual slope soil layers and its drilling process. Background Technology

[0002] Traditional drilling equipment faces numerous challenges when conducting large-diameter borehole operations in complex geological conditions such as thick residual slope soil layers. These soil layers typically exhibit complex particle size distribution, loose structure, and poor stability, resulting in low drilling efficiency and a high risk of borehole wall collapse or deformation. This places extremely high demands on the support stability and adaptability of the drilling equipment. Most existing conventional drilling equipment is simply designed and lacks effective solutions for such special working conditions.

[0003] Due to the undulating terrain and low surface bearing capacity, traditional drilling rigs with fixed supports struggle to maintain balance, posing a significant risk of overturning during drilling operations. Furthermore, the equipment's large size and inconvenient transportation hinder rapid site evacuation and relocation. In soft soil, even minute borehole deviations can trigger borehole wall collapse. However, most equipment lacks a precise center-of-gravity adjustment mechanism, failing to compensate for eccentric moments through counterweight balancing, further complicating operations.
