Abstract:

In order to build a low-carbon, energy-saving and environmentally friendly utility tunnel, a number of technological innovations in engineering design such as pipeline selection, cross-sectional setting, pipeline layout in the cabin and node function expansion have been made in the utility tunnel of Hong Kong University of Science and Technology (Guangzhou), which are to reasonably determine the types of pipeline into utility tunnel for reducing the cabin size and simplifying the ancillary facilities, use the single-cabin large-section multi-layer pipeline intensive layout for improving the utilization of internal space, build a three-dimensional data model of the area along the utility tunnel for accurately determining the ground elevation of utility tunnel during the design, install the reserve pipe in ring layout for the important pipelines to improve the supply reliability, and adopt the innovative node function technologies for achieving the intensive, energy-saving and efficiency. The application of the innovative technologies play an extremely important role in optimizing the engineering schemes, saving the underground space resources, and realizing the green and low-carbon construction, which is the direction of the development and application of innovative technology in the construction of utility tunnel projects.
