合肥高新区综合管廊典型节点设计探讨

Design Discussion on Typical Joints of Utility Tunnel in Hefei Hi-Tech Area

合肥高新区综合管廊一期工程共7条管廊,除雨水不入廊外,其余市政管线全部入廊。管线种类及规格众多,7条管廊沿7条道路分布且相互交叉,存在着各种特殊节点设计。针对设计过程中的几个典型节点作探讨、分析,为类似工程提供借鉴和参考。

In the first phase of utility tunnel project of Hefei Hi-Tech Area,there are 7 utility tunnels.Except for the rainwater no-entering the tunnel,the other municipal pipelines are all in the tunnel.There are many types&specifications of pipelines.7 utility tunnels are distributed along 7 roads and intersecting with each other.There are various special node designs in the project.A few typical nodes during the design process are discussed&analyzed,which may provide references for similar projects.
