新建地下结构与现状管线管廊结合的设计与研究

Design and Research on the Combination of New UndergroundStructures and Existing Pipeline Corridors

针对新建地下结构与市政管线位置冲突,且因条件受限管线无法有效迁改的情况,探讨了地下结构预留管线路径的解决策略。结合工程实例,根据管线埋深与地下结构的位置关系,分别考虑与地下结构底板合建、顶板合建以及侧墙开孔横穿等情况,分析建造实施关键节点的设计方案与特殊处理方式,其成果可供相关工程参考。

In response to the conflict between the location of newly built underground structures and municipal pipelines,and the inability to effectively relocate pipelines due to limited conditions,this paper explores the solution strategy of reserving pipeline paths for underground structures.Based on engineering examples and the relationship between the buried depth of pipelines and the location of underground structures,consideration was given to situations such as joint construction with the bottom plate of the underground structure,joint construction with the top plate,and cross cutting of side wall openings.The design scheme and special treatment methods of key nodes in construction and implementation were analyzed.The results can be used as a reference for similar projects.
