摘　　要：旋挖钻机目前是全球范围内施工钻孔灌注桩时的主流施工设备,其在施工钻孔灌注桩时,受一些内在和外在因素的影响,常常导致开挖后竣工桩位偏差值超限,影响验收质量,造成不好的社会影响和一些不必要的经济损失,该文重点介绍该设备施工钻孔灌注桩时桩位偏差产生的原因及注意事项。以期为验收质量做保障。At present, rotary drilling rig is the mainstream construction equipment in the construction of drilling and pouring all over the world. During the construction of drilling and pouring, it is often affected by some internal and external factors, which often leads to the overrun of the completed pile position deviation after excavation, affects the acceptance quality, and causes bad social impact and some unnecessary economic losses. This paper will focus on the causes and precautions of the pile position deviation in the construction of drilling and pouring piles with this equipment.In order to ensure the quality of acceptance.
