摘　　要：桩基是一种常见的地基处理方式,具有适应性广、单桩承载力高等优势,适合各种地层。桩基施工过程中,孔口坠落是很常见的安全事故类型,在伤亡事故中占很大比例,而针对桩孔上口的防护措施却没有具体规定。通过参考相关标准规范,结合实际工作经验,从桩孔上口设置防护网、搭设防护栏杆和在栏杆上悬挂安全标识三个方面详细介绍了一种桩孔上口防护措施。该防护措施能做到对桩孔上口的良好防护,满足后续桩孔检测需要,同时取材方便,坚固耐用。通过严格落实,降低了孔口坠落风险,提高了安全施工的水平。Pile foundation is a common foundation construction method,which has the advantages of wide adaptability and high single pile axial capacity.In the process of the pile foundation construction,falling is a very common type of safety hazard,which accounts for a large proportion of casualties,and there are no specific provisions for the protection measures for the top of the open pile borehole.By referring to relevant standards and norms and combining actual work experience,this paper introduces in detail a composite pile borehole top protection measure from three aspects:setting up protective nets,erecting protective railings and hanging safety signs in the railings.The protection measure can achieve a good protection for the upper opening of the pile borehole,meet the needs of the subsequent pile borehole detection,and at the same time,the material is convenient and durable.Through the strict implementation,the risk of falling potential at the borehole opening is reduced and the level of safe construction is improved.
