Abstract:

The ancillary facilities of the urban road tunnel are an important part of the urban road tunnel. Subsidiary facilities have always been the focus and difficulty of urban road tunnel design because of their large volume, complex function, occupation of urban land, with exhaust wells (pollution sources) and other reasons. In order to solve the problem of arranging the ancillary facilities in the design of urban road tunnels, this paper takes the arrangement of the ancillary facilities of the urban road tunnel (underground equipment room) as the research object, categorizes the types of the ancillary facilities of the urban road tunnel, summarizes its functions and characteristics, and uses it as a basis from the pre-location, The factors that need to be considered in the design process and the landscape design of the ground-building structure are summarized and summarized in combination with the actual case. Finally, the method of arranging the ancillary facilities of the city road tunnel is put forward, that is, through the pre-planning, multiprogramme selection, focusing on solving the main contradictions of the ancillary facilities, reducing the influence on the surrounding area on the basis of meeting the function, and finally realizing the harmony and unity of the urban road ancillary facilities and the surrounding environment.

Key words: city tunnel, ancillary facility, layout plan
