- Abstract:
- Heyan Road-Baguazhou river crossing tunnel in Nanjing is a shield tunnel with two holes. In order to solve the current water supply problem of Baguazhou and effectively utilize the lower space of the tunnel, a DN500 water supply pipeline was set up under each tunnel inspection cabin to connect the water supply network of Baguazhou and the water supply network of Jiangnan Chengbei waterworks, so as to realize water supply of Baguazhou from Jiangnan. The maximum discharge of the pipeline, optimal selection of pipes, setting of ancillary facilities, monitoring and control system and simulation of water hammer and prevention and control measures were explored, and feasibility of laying water supply pipeline in the tunnel was demonstrated. A series of measures were taken to ensure the safety of the synchronous operation of the water supply pipeline and the tunnel, and reduce the interaction between them, which provide a reference for similar projects in future.
