城市共同管沟排水设计的探讨

Probe into the drainage design of urban utility tunnel

随着我国城市共同管沟的发展,城市共同管沟内部的管线不但数量越来越多,而且种类也越来越复杂,其排水问题变得日益重要。根据以往城市共同管沟的设计经验,结合纳入给水管和消防管的青岛胶州湾海下隧道工程,提出了针对城市共同管沟排水设计的一些看法。

With the development of urban utility tunnel, pipes in the urban utility tunnel increase in not only the quantity but also the types. Meanwhile, drainage problems of utility tunnel become more and more important. Based on previous urban utility tunnel design experience and the practical Qingdao Jiaozhou bay underground tunnel which includes water supply pipe and fireprevention pipe, this paper proposed some suggestions about the urban utility tunnel drainage design.
