摘　　要：本研究旨在通过对抗浮锚杆关键技术进行优化,减少传统施工方法对锚杆施工质量、效率和成本的不良影响。采用锚杆施工分区结合航拍正射图的新方式,完善施工部署;通过可旋转锚杆垂直吊放接头的使用,解决了吊放不垂直的问题;通过护筒与锚杆同钻进技术,减少了孔壁坍塌问题;利用抗浮锚杆本身强度高的特性,兼做底板顶层面筋的钢筋支架等。研究结果表明,通过技术优化,抗浮锚杆的质量、工期和成本等方面得到了较大改善,可为相关领域的学者和从业人员提供宝贵的指导和参考,以推动抗浮锚杆施工技术的进一步发展和优化。This study aims to reduce the impact of conventional construction procedures on the construction quality,efficiency and cost of anchor bolts by optimizing the key technology for anti-floating anchor bolts.A novel combination of anchor bolt construction zoning and aerial orthographic maps to improve the construction deployment.The rotary connector for vertical lifting of anchor bolts can be used to keep anchor bolts upright in the lifting process.Drilling is carried out for casings and anchor bolts at the same time to reduce the collapse of holes.High-strength anti-floating anchor bolts can also be used as a reinforcement support for the upper surface at the bottom.Research results show that the quality,duration and quality of anti-floating anchor bolt construction have been greatly improved by technological optimization,thus providing a valuable guide and reference for scholars and practitioners in related fields.This will also promote the further development and optimization of the construction technology for anti-floating anchor bolts.
