The invention relates to an auxiliary management system for subway integrated pipeline construction. The system comprises a user management module, a three-dimensional management module, a construction management module and a logging module, wherein the user management module comprises user login authentication and logging off function; the three-dimensional management module comprises scene import, three-dimensional roaming, layer management, legend management and navigation functions; the construction management module comprises basic information management, pipeline modification management, spatial analysis, pipeline collision detection, process coordination, construction schedule management functions; and the logging module can record information on user operation on pipelines in real time. The auxiliary management system for subway integrated pipeline construction provided by the invention has the beneficial effect that three-dimensional visualization of construction process management is realized, so that construction schedule is more visual, and the representation of construction management effect is enhanced, and rework in pipeline construction process is effectively avoided; and through spatial analysis and pipeline collision detection means, the problem of spatial collision between professional pipelines can be effectively solved, and the smooth progress of projects is ensured.
