摘　　要：结合工程实际案例,介绍了一种地下室顶板侧梁开洞加固及防水施工工艺。经技术团队优化,提出采用粘钢加固与套管安装相结合的方案:梁内外侧采用粘钢加固,套管与粘钢焊接。现场实践证明,此种工艺施工简单、施工周期短,既能达到洞口加固目的,又能保证外墙防渗漏质量,为地下结构开洞等类似情况提供了较好的解决方案,值得推广应用。Combined with practical engineering cases,this paper introduces a hole opening reinforcement and waterproof construction technology of basement roof side beam.After optimization by the technical team,the scheme of combining bonded steel reinforcement with casing installation is proposed.The bonded steel reinforcement is adopted for the inner and outer sides of the beam,and the casing is welded with bonded steel.Field practice has proved that this process has the advantages of simple construction and short construction period.It can not only achieve the purpose of hole reinforcement,but also ensure the anti-seepage quality of external wall.It provides a better solution for similar situations such as underground structure opening,and is worthy of popularization and application.
