- Abstract:
- The construction of utility tunnel in complex environment is facing many difficulties such as complex current pipeline, limited space, multidisciplinary collaboration, safe construction, short construction period and public opinion. In the design of Qingdao Aodong Road utility tunnel project, the section layout was determined from the perspective of safety grade of the pipeline entering the tunnel, the degree of installation difficulty and mutual influence. According to the buried depth of the main tunnel and the importance of the branch pipeline, the cross branch and the directly buried branch were selected respectively. A node integration classification scheme was innovatively proposed, and the complex nodes were optimized and integrated by using BIM technology. According to the geological conditions and environmental factors, sloping support and vertical support were adopted. Under the premise of meeting the planning and use functions, the investment was saved, the construction period was shortened and the construction safety was achieved.
