浅谈城市道路快速化改造中的管线迁改

Brief Discussion on Pipeline Relocation in Reconstruction of Urban Road to Expressway

摘要:

为有效缓解城区内部交通压力，提高对外交通沟通效率，国内许多城市正在建设或计划建设城市快速路系统。由于快速路桥墩众多，对地下管线破坏较大，虽然管线工程在整体快速路建设工程中占比不大，但对整个项目的设计方案、施工工期都有着重要影响，尤其是国防光缆、涉铁管线、高压输气等管线，对项目的进度有至关重要的影响。现对管线迁改的设计方案、实施方案和实施重难点进行总结和探讨，希望对其他类似工程提供有益参考。

Abstract:

In order to effectively alleviate the internal traffic pressure in urban areas and improve the efficiency of external traffic communication, the urban expressway system is been constructing or planned to build in many cities of China. Because of the numerous piers of expressway, the damage to underground pipeline is large. Although the pipeline engineering accounts for a small proportion in the overall expressway construction project, it has an important impact on the design scheme and construction period of the whole project especially on the national defense optical cable, pipeline involving railway, high-pressure gas transmission pipelines and other pipelines, which have a crucial impact on the project progress. The design schemes, implementation schemes, and implementation focuses and difficulties of pipeline relocation are summarized and discussed, hoping to provide the useful reference for the other similar projects.
