The Research On Waterproof And Drainage And Rainwater Utilization For The Platform Of Open Type Metro Depot

The rapid development of national economy in our country promote the urbanization process accelerated, prompting entered the stage of fast urban rail transit development in our country.At the same time promote the city increased the urban rail traffic facilities construction. One of the most important is the urban rail transit planning. It guarantee the normal operation of urban rail transit system. However, its huge size and growing tensions of urban land resource has a huge conflict.Faced with this contradiction people introduced the concept of open type metro depot.Through three-dimensional construction, property development and other means to develop the depot.To realize the intensive use of urban land.Thesis seize the new construction mode,using the open type metro depot as the subjects.To research the waterproof and drainage and rainwater utilization of the big platform.These problems unfold around the rainwater.Main research content of thesis is divided into four parts:First is the research on drainage problem of the large platform of the depot, including the choice of the ways of drainage, the organization design of drainage and emergency water drainage design. Through the study of the existing theories of drainage and the difficulties of the drainage of big platform,we find the way applicable to the drainage and the organization.Finally,as a supplement we add the emergency drainage measures.The second is the research on waterproof problem of the big platform of metro depot.Waterproof problem research is divided into to the junction waterproof and deformation joint waterproof.Through the collation of the existing construction practices,we screened the waterproof construction practices of every parts.Then is the study of the rainwater utilization for the big platform.Rainwater utilization is rarely used in the completion depot and is the hot issues in the future.In the paper I collation the various methods of analysis of rainwater utilization at home and abroad.Finally I collation the green roof,high flowerbed and some other methods can be used on the big platform of depot.The final design is the application of the above conclusion.We selects the Sihui depot as our research object.Through consulting data, field survey and expert interview,we analysis of the waterproof and drainage and rainwater utilization of Sihui depot.At last,I Application of the above conclusion to Comparative analysis with the status quo,then put forward some optimization tips.
