Study On Underground Pipe Gallery Feasibility In Shiyan City

Underground pipe gallery achieves centralized management of water,electricity and gas,which is one of the important sign of construction of city underground pipeline facilities modernization.The construction of underground comprehensive pipe gallery can prevent the rupture of pipes,eliminate the repeated excavation of the road,which has great significance for city construction.Based on the basic concept of city underground pipe gallery,city planning theory,system theory and the theory of public goods management theory and other basic theory,analyze the necessity and feasibility of Shiyan city center underground pipe gallery system construction.Based on the investigation of underground pipe gallery and pipeline status in Shiyan city,we discussed the existing problems of city underground pipe gallery,analyzes mathematical-model in plannning of urban underground integrated pipe gallery system.We also research the construction and management of Underground pipe gallery.(1)Based on safety of water and using of underground-space,we analyzed the necessity and feasibility of underground pipe gallery construction in Shiyan city.(2)We analyzed a series of problems existing in the planning,design,operation mechanism,charging standard,comprehensive management mechanism and the establishment of comprehensive pipe gallery system of Shiyan underground pipe gallery.Through the analysis found that the constraints of the problem lied in the urban underground comprehensive pipe gallery mechanism and construction process factors,personnel and technical equipment factors and social environment factors.And we put forward a series of measures to improve Shiyan city center underground pipe gallery system,through the improvement of the top-level layout and operation mechanism,innovation and standardized planning and design,construction and construction organization innovation,perfect charging system and operation mode,change the comprehensive management measures,to improve the comprehensive pipe in the center of the city underground system in Shiyan city.(3)Planning of underground pipe gallery is related to multi-target optimization.The evaluation index system of underground pipe gallery is established,it is composed of target layer,index layer,scheme layer.We establish mathematical-model based on multi-target decision and fuzzy mathematics,judge each scheme,achieve optimal plan.The operability of the model contribute to intellgent planning and design of underground pipe gallery(4)We tried to do the establishment of the city underground pipe gallery frame system,from the top-level design,layout and planning environmental impact assessment and construction,operation mechanism and management model(PPP)to construct Shiyan city center underground pipe gallery system,efforts to resolve the emergence of city underground pipe gallery in question.In the top-level design and layout were analyzed from the aspects of water supply and drainage pipeline layout,sewage and rainwater pipeline layout,power and communication pipeline layout,gas and heating pipeline layout and pipe gallery system layout;in comprehensive pipe gallery planning and design,planning,planning,selection of section line planning,3D control sets and ancillary facilities planning from the aspects of pipe gallery are analyzed.
