| At present our country there are numerous companies and enterprises to participate in urban underground pipe network construction,including planning bureau,cons truction bureau,urban management bureau,transportation bureau,electric power company,gas company,water company,telecommunications companies,which include water supply,wastewater,rain water,gas,electricity,mobile network and so on the many kinds of pipeline.Because of various pipelines in construction process are managed by different units,so caused in pavement construction,pipe laying,cross connection,easy mutual interference,the destruction,the road,has been paralyzed pavement damage is serious,underground pipe network of chaos.Therefore,research and extension is more safe and reasonable layout of comprehensive underground pipeline corridor,and the other project construction has a guiding value in the design of underground integrated wiring project,has certain positive meaning.This topic main research of lanzhou JingNing road Municipal tunnel engineering plan,the purpose is through to the present situation investigation and analysis of the pipeline,and four of the comprehensive utility tunnel scheme comparison,of lanzhou city JingNing Municipal tunnel provides a feasible,safe and economic solutions,and the engineering design field play a role of reference and exemplary role.This project research mainly from the following three aspects,respectively is:1.Analyze and determine the Municipal tunnel into the corridor of pipeline,than choose practical feasible comprehensive utility tunnel section optimization.2.The Municipal tunnel engineering design,including the cross-sectional,routing,construction sequence,and so on.3.The analysis of the accessory works,among them especially for fire control system are analyzed in detail;Summarized the influence of the project on the surrounding environment,the evaluation of soil and water conservation,social risk and the evaluation of various benefits.Paper for more than four research content was studied,this paper mainly got the following results:1.This provides the research plan has four,through the cross section,investment,economic construction,operation management and structure of the four aspects has carried on the comprehensive comparison,the conclusion for plan B(except the rain water pipe,gas pipe and other pipe into the Municipal tunnel)is feasible.2.Power lines need to attach great importance to it in other pipeline comprehensive utility tunnel is one of the most has the possibility of the fire itself.Through the comparison ofvarious kinds of fire extinguishing equipment,this study determined the pulse superfine powder extinguishing equipment for the safe,reliable and practical fire extinguishing equipment.3.The Municipal tunnel construction will inevitably influence on the region along the ecological environment quality.In order to make these effects to a minimum,the project in the process of construction and management must take the necessary measures. |
