It was recently learned from the Standing Committee of Nanning Municipal People’s Congress that the Regulations on Administration of Nanning Underground Utility Tunnel (short as the “Regulations”) will come into effect on November 1, and the pipelines will be forced to enter the tunnel in the future. At the same time, in order to ensure the safety of underground utility tunnel and underground pipelines (especially gas, water supply and drainage, and electricity), the “Regulations” also stipulate the establishment of safety protection area and safety control area, and strengthen the safety management of the two areas and the control of construction operations affecting the safety of tunnel in addition to emergency rescue.
The underground utility tunnel is important to solve “road zipper”. Up to now, Nanning has built a total length of 63.73 km of tunnel, with an investment of 5.373 billion yuan. These projects play an active role in reducing road excavation, strengthening centralized maintenance and management of pipelines, and intensively using underground space.
