The Urban Construction Of Underground Pipe Network

Underground pipe network, known as "the underground lifeline." is a vital component of urban infrastructure, which is an essential material basis of urban life, it bears a city sewage, energy, information and other important necessities of delivery as well. Since the 80’s, with the rapid development of the city, the construction of underground pipe network in cities gains its importance increasingly. Currently, however, there remains a social drawbacks which lies in many cities---"zipper road"---that is a special phenomenon that it is often observed in the urban road construction, reconstruction and expansion, with the repeated and disordered excavation and having been into a state of construction for a long period. It is not only inconvenient to people, but also causes a great waste of resources. It is imperative to achieve the scientific integrated management of underground pipe network, assemble the urban underground "lifeline", and optimize the urban underground space---that is a major action and global decision in urban construction. Construction of utility tunnel is a crucial pathway to cope with the "zipper road", which can effectively reduce or avoid the influence and interference on city traffic and residents’living, as it is due to the frequency of laying and maintenance of underground pipeline, and can keep the integrity and appearance of the roads as well. To sum up, building the utility tunnel is the trend in urban infrastructure construction in the future.
