摘要
文章结合工程实例,阐述了过江管道设计中的航道通航和防洪要求,以及管道标高、管材、管径、防腐等技术要求,设计实例涵盖了顶管过堤、沉管过江、江中对接等多项市政给排水过江管道设计中的重难点,以期为同类项目技术方案的制订提供参考。
Combined with engineering examples, this paper expounds the requirements of waterway navigation and flood control in the design of river-crossing pipelines, as well as the technical requirements for pipeline elevation, pipe materials, pipe diameter and anti-corrosion. The design examples cover many key and difficult points in the design of municipal water supply and drainage river-crossing pipelines, such as pipe jacking crossing the embankment,immersed pipe crossing the river and river docking, so as to provide references for the formulation of technical schemes of similar projects.
