雄安新区雄东片区综合管廊工程总体设计

Overall Design of Utility Tunnel Project in Xiongdong District of Xiong'an New Area

雄安新区窄路密网的新型城市道路布局理念、错综复杂的地下空间、全生命周期智能建造体系等特点显著增加了综合管廊的设计难度。以雄东片区综合管廊工程为例,探讨了窄路密网条件下大、小市政管线衔接方案,提出以支管廊出线为主,局部采用管线分支口直埋出线的解决方案;管廊穿越复杂地下空间处,结合两者建设时序选用合理的建设模式;以入廊给水管道为例,研究BIM建模要点,满足新区数据交付标准。

There are many factors in Xiong'an New Area that significantly increase the difficulty in the utility tunnel design,such as the new urban road layout concept of narrow road and dense network,complex underground space and the whole life cycle intelligent construction system.Exemplified by the utility tunnel project in Xiongdong District,this paper discussed the connecting scheme between large and small municipal pipelines under the condition of narrow road and dense network,and proposed the solution that the branch utility tunnel mode was mainly used and the directly buried outlet pipeline branch was adopted in specified locations.When the utility tunnel passed through the complex underground space,the reasonable construction mode was selected according to their construction sequence.The key points of BIM modeling in a water supply pipeline were discussed to meet the digital standards in the new area.
