How to improve the stability and safety of horizontal directional drilling rigs?
Dec 03, 2025| 1. Application of prestressed technology: Prestressed technology, such as reinforced concrete support and steel strand prestressed support, can effectively improve the compressive strength and stability of the borehole wall.
Through prestressed construction, the overall stability of the borehole wall can be enhanced, preventing borehole collapse during drilling and ensuring safe construction.
2. Underground grouting technology: Underground grouting technology can form a solid coating on the borehole wall, filling the gaps between rock strata and enhancing the integrity and airtightness of the borehole wall.
This not only improves the compressive strength and stability of the borehole wall but also helps prevent the leakage of water and mud from the formation, further ensuring construction safety.
3. Rational construction strategy planning: Before construction, the geological conditions of the crossing location should be thoroughly investigated, and the drilling trajectory should be rationally designed to avoid unfavorable strata as much as possible.
In complex geological environments where avoidance is not possible, measures to reinforce the soil layer can be taken, such as grouting to consolidate the rock and soil, to improve the stability of the borehole.
4. Optimize Mud Management: Rationally set the mud pressure within the borehole to avoid pressure fluctuations.
Add special reagents to the mud to prepare high-efficiency mud and improve its lubricity to meet the needs of different projects.
5. Establish and Improve Safety Management Systems: Establish and improve enterprise safety management rules and regulations, clearly define the responsibility system for safe production, and decompose safety production tasks layer by layer, assigning responsibility to specific individuals.
Strengthen employees' self-protection and self-prevention awareness, and improve their safety awareness and skills.
6. Selection and Maintenance of Advanced Equipment: Select high-performance construction equipment and equip it with skilled machine operators to ensure stable equipment operation.
Perform daily maintenance and upkeep of the equipment, promptly troubleshoot malfunctions, and ensure that the equipment does not experience unexpected situations during construction.
