Recently, the PPP project of the Utility Tunnel Engineeringdedicated to the Shantou Bay New Area on the east coast of the city, which has been built to serve the city for 100years, has resumed its work and is expected to complete the main body construction of the tunnel by the end of this year.

It is a 14.65 km tunnel project to be newly built in XinxiArea, whichconsists of the main body construction of the utility tunnel, fire-fighting system, sidewalk and overhaul channels, identification system, electrical system, automatic control system, monitoring center and other ancillary facilities.In order to meet100-year service life requirements, the project adopts the design scheme of "three compartments", namely, power supply compartment, communication and pipeline (water supply) compartment and gas pipeline compartment.In addition to drawing on the experience of underground utility tunnel construction in Shenzhen, Xiamen and other cities in south China, the project also uses the concrete technology ofHong Kong-Zhuhai-Macao Bridge for reference, and provides with triple waterproofing facilities both inside and outside with a view to prolonging the service life of concrete.

The construction of utility tunnel in the Shantou Bay New Area on the east coast of the city will not only provide a power supply channel for the 2021 Shantou Asian Youth Games to ensure the successful holding of the big event, but also will effectively avoid the impact and interference on traffic and residents' travel caused by frequent excavation of roads forunderground pipelines laying and maintenance, hencemaintaining the integrity and overall appearance of roads.
