结合工程实例,介绍了市政污水管带水碰管施工方案需确保的前提及需考虑的现场条件,并从降水施工、管道固定、清碴准备等方面,阐述了具体的施工方案,最后经证实,该施工方案具有可行性,对后续管道有水、水位高的碰管施工具有参考价值。 Combined with the project examples, the preconditions to be ensured and the site conditions to be considered in the construction of municipal sewage pipe and water pipes were introduced. The concrete construction plans were expounded from the aspects of precipitation construction, pipeline fixation and preparation of clean ballast, and finally confirmed , The construction scheme is feasible and has reference value for the tube-in construction with subsequent water and high water level.
