正公路快速化改造工程管线迁改方案研究

Study on Pipeline Relocation Scheme of Zhenggong Road Expressway Reconstruction Project

摘要:

在快速路改造工程的管线迁改工程中，因为其管道种类和规模远大于一般道路，相较于普通市政道路有更严格的道路保通要求，且面临跨部门管理，其复杂性远高于普通的管线迁改项目。以成都市正公路快速化改造工程为例，探讨了此类工程遇到的问题，并提出了相关的设计思路。结果表明，与一般情况不同，在快速路改造过程中的管线迁改工程需考虑更多控制因素（诸如管道废除、临时新增管线和道路保通等），需根据不同要求进行方案设计。

Abstract:

In the pipeline relocation of expressway reconstruction project, there are more strict requirements for ensuring the road traffic than the ordinary municipal roads because of its pipeline types and sizes much larger than that of ordinary roads. And it faces the cross-departmental management. Its complexity is much higher than that of ordinary pipeline relocation projects. Taking the Chengdu Zhenggong Road Expressway Reconstruction Project as an example, the problems met in this kind of project are discussed, and the relevant design ideas are proposed. The results show that compared with the general construction project, there are more control factors such as the abolition of pipelines, the temporary addition of new pipelines and the guarantee of road traffic required to consider during the expressway reconstruction, and the scheme design should be carried out according to the different requirements.
