摘要
根据某工程的地层情况,通过对旋挖钻机试成孔情况描述及方案比选,决定采用人工挖孔护壁方案,详细阐述了人工挖孔护壁控制要点及安全措施,为同类工程施工积累了宝贵经验。
According to the layer situation of one project, it describes the pore-forming situation on rotary drilling rig and selects scheme to decide the adoption for artificial wall protection scheme. This paper introduces the control points and security measures of artificial wall protection in detail to accumulate valuable experience for similar projects.
