The Study On The Planning And Construction Of Underground Corridor System In Towns And Mid-sized Cities

Urban underground pipelines are an important part of urban infrastructures,which supports the operation and development of the city.In recent years,the process of urbanization in China has been accelerating,and the construction of urban infrastructure has also been on the rise.The types and quantities of underground pipelines have been increasing.However,due to the legacy of our country and other factors,China' s underground pipeline construction problems are quite a lot,such as pipeline separate management,the lack of reasonable planning and other issues are also very prominent.In order to improve the constructions and management of underground pipeline chaos,underground corridor construction has attracted wide attentions by all levels of governments.In order to make allocation of urban resources more rational and to save economic costs,Yanji City began planning the construction of underground corridors in 2009.This paper will take Yanji City as an example to analyze the planning and construction of underground corridors in small and medium-sized cities in China and put forward practical solutions for reference.First of all,the paper introduces the background and purpose of the planning and construction of the underground integrated corridor and systematically expounds the theoretical research on the establishment and construction of the underground integrated corridor at home and abroad,summarizes the laying way of underground pipelines,and discusses the advantages and disadvantages of various laying methods Put forward the need to build underground integrated corridor.Secondly,it analyzes the conditions and necessity of Yanji city planning and construction of underground integrated corridor.From the size of the two aspects were described Yanji City is fully capable and necessary to plan the construction of underground integrated corridor.Thirdly,the present situation and existing problems of the underground pipelines in Yanji city are analyzed in depth.The problem is mainly discussed from two aspects:the systemic problems of municipal pipelines and the construction of municipal pipelines.Fourthly,the layout of the underground integrated corridor of Yanji City,pipeline corridor,ancillary works and supporting facilities planning were analyzed,the existing planning and construction of the existing shortcomings,and the people of the road integrated corridor as a case,The compatibility of the ducts and the cohort lines were analyzed.Finally,summarize the content of the full text,propose solutions and recommendations to the shortcomings mentioned in the paper.
