坚硬斜岩地质条件冲击钻钻孔施工技术

Percussion drilling construction technology in hard inclined rock geological conditions

冲击钻是桩基施工领域较为典型的成孔工艺,遇孤石及倾斜岩层等特殊的施工地段时,易出现钻进速度大幅度下降的情况。文章结合工程实例,根据施工现场坚硬斜岩地层的实际特性,探讨相适应的冲击钻钻孔施工技术,阐述施工中需重视的技术要点,为相关人员提供参考。

Percussion drilling is a typical hole-forming technology in the field of pile foundation construction.When encountering special construction sections such as boulders and inclined rock formations,the drilling speed is likely to drop significantly.Based on engineering examples and the actual characteristics of the hard inclined rock formations at the construction site,this article discusses suitable percussion drilling construction techniques,expounds the technical points that need to be paid attention to in construction,and provides references for relevant personnel.
