摘　　要：结合某城乡污水处理厂尾水排放管道工程施工实际,介绍了水平钢顶管内预留垂直顶升洞口施工工艺流程,探讨并总结了该工艺在施工过程中的关键技术及重难点问题改进措施。施工结果表明,该工艺较大程度上避免了管道顶升过程中出现的渗漏现象,可为今后类似工程提供参考。Combined with the construction practice of tailrace drainage pipeline project of a sewage treatment plant in rural areas, this paper introduces the construction process of reserving vertical jacking hole in horizontal steel pipe jacking, and discusses and summarizes the key technology and the improvement measures of key and difficult problems in the construction process. The construction results show that the technology avoids leakage phenomenon in pipeline jacking to a great extent, and can provide reference for similar projects in the future.
