The Development of Common Duct in Taiwan and Its Enlightenment to China

Abstract

Utility tunnel built in the urban underground is used to hold two or more urban pipeline engineering structures and ancillary facilities, that is also known as the common duct in Taiwan. The construction of utility tunnel can effectively eliminate the "zipper of the road" and reasonably use underground space, which is the important direction of modern smart city in sustainable development. This paper summarizes the development course of common duct in Taiwan area and discusses its accomplishments from construction achievements, the legal system, funding sources, system planning and public pipeline database. On this basis, according to the existing problems in the development of utility tunnel in China, this paper points out some enlightenments that China gets from the development of common duct in Taiwan, so as to provide positive enlightenments for large-scale construction of utility tunnel in our country.
