How to avoid complex geological conditions when drilling with a horizontal directional machine?

1. Detailed geological survey
Carry out comprehensive and in-depth geological surveys, including the use of a variety of survey methods, such as geological drilling, geophysical exploration, etc.
Increase the density of survey points to more accurately understand the changes in underground geological structures.
2. Collect historical geological data
Review local geological archives and data from previous similar projects to understand common geological problems and complex situations in the area.
3. Communicate with relevant departments and experts
Communicate with local geological departments, university geological experts, etc., and obtain their opinions and suggestions.
4. Optimize drilling route planning
When designing drilling routes, try to avoid known geologically complex areas, such as fault zones, karst cave development areas, etc.
5. Use pre-support and pre-treatment technology
For areas where complex geology may exist, pre-support is carried out before drilling, such as grouting to strengthen the stratum.
Pre-treat possible obstacles, such as clearing or crushing.
6. Make emergency plans
Despite taking precautions, unexpected situations may still occur. Develop detailed emergency plans so that effective response measures can be taken quickly when encountering complex geological conditions.
