Abstract:With the continuous progress of urbanization in China and the continuous expansion of urban areas, highway increasingly assume the functions of urban roads, and there is an urgent need for municipal supporting construction. However, due to historical and institutional reasons, these roads still belong to the highway department and are subject to the relevant regulations and standards of highway, resulting in many problems in the municipal supporting construction that conflict with the regulations and regulations of highway, making it difficult to promote the municipal construction of highway. Based on the construction project of a national highway pipe gallery in Qingdao, Shandong Province, this paper puts forward some design ideas on how to improve the construction of pipe gallery on the existing highway, and provides reference for the promotion of other similar projects.
