Abstract: 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.
