SPT drilling rig is a kind of precision equipment designed for geological exploration and geotechnical engineering. Its core advantage lies in the hydraulic drive system and intelligent control module, which accurately obtains stratigraphic parameters (e.g. N-value, lithology distribution) and provides reliable data support for construction projects and mine development. Compared with traditional drilling rigs, its modular design reduces transportation costs by 40%, and 90% of the operation steps can be completed by a single person.

Rack mounted spt soil test drill rigs application
SPT drilling rigs are widely used in engineering geological surveys, environmental monitoring, and resource exploration:
- Construction engineering: assessing foundation bearing capacity, landslide risk, and providing geomechanical data for high-rise buildings, bridges, and tunnels;
- Mineral exploration: quickly locate the ore layer and analyze the core composition (e.g. gold grade, shale gas content) in metal mine, oil, and gas field drilling;
- environmental engineering: monitoring soil pollution diffusion, underground hydrological characteristics, and supporting ecological restoration projects;
- Disaster prevention and control: Early warning of earthquake fault zones and mudslide risk areas through stratigraphic structure analysis;
- scientific research: polar glaciers, deep-sea sediment sampling, and other cutting-edge research.
Advantages of SPT drilling rig
- real-time monitoring screen: displaying 20 parameters such as drilling pressure, rotational speed, mud flow rate, etc., with an automatic warning for data deviation over the limit;
- AI core recognition: analyze the rock chip morphology through the camera, and initially judge the formation lithology (accuracy rate ≥85%);
- cloud storage: automatically generates drilling logs and synchronizes them to the project management platform, reducing manual recording errors.
