人工挖孔桩特点因需井下作业施工、施工环境恶劣、劳动强度大、施工安全要求高等因素,被许多地区列为建设领域限制使用的范畴。但曲于施工方便、不需要大型机械设备、单桩承载力与受力性能可靠、抗震能力强,在局部地区仍在运用,如何对人工挖孔桩的施工进行质量和安全控制,是值得探讨的一个问题。 Due to the need of downhole work construction, harsh construction environment, heavy labor intensity and high construction safety requirements, the characteristics of manual digging pile are listed in many areas as restricted areas in the construction field. However, it is convenient for construction and does not require large-scale machinery and equipment. The bearing capacity and stress-bearing performance of single pile are reliable and the anti-seismic capability is strong. It is still used in some areas. How to control the quality and safety of manual digging pile is worth discussing A problem
