Roof Garden Construction Technology Research

Since the reform and opening up,China's urban construction has been developing rapidly.However,urban heat island effect,ecological and environmental pollution,public green tension and other issues gradually prominent.The emergence of Roof garden,to improve the since the reform and opening up,China's urban construction has been developing rapidly.However,urban heat island effect,ecological and environmental pollution,public green tension and other issues gradually prominent.The emergence of roof garden improves the above problems with greater help to become a new form of urban greening.In this paper,the development course,functional value and basic types of Roof garden are studied.The study and Analysis on the greening project of the urban greening in Xi'an City,summarizes the bottleneck and problems existing in the construction of Roof garden,and studies the solution strategy of the problem.At the same time,to Xi'an City,"the space city set sail ICB" staff restaurant for example analysis of the Roof garden.The purpose of this paper is to analyze and discuss the key technical problems of Roof garden.In this paper,the investigation--Analysis--empirical research ideas.First of all,the 9 Roof garden cases in Xi'an are studied on,such as residential areas of roof garden,public buildings roof garden,and industrial building roof garden.Pointed out that the main technical bottlenecks of Xi'an Roof garden,relates to the structural system,cultivation,the load of the roof waterproof leak,etc...Secondly,the solution of the above problems is obtained through the logical analysis.One is the structural system of Roof garden including modular,structural,ultra light and thin system.The structure of Roof garden belongs to the vegetation layer,planting soil(planting matrix),filter layer,layer,drainage and storage root resistant layer(Zu Genceng),waterproof layer,insulating layer,structure layer.Two is the Roof garden planting project.Analysis of substrate composition and thickness of the Roof garden in Xi'an City,recommended common plants,with isolated planting trees,flower beds,etc.landscape planting form glasses.Three is the Roof garden load problem.Roof garden loads include planting area,potted flower beds and load load,Roof garden,rockery waterscape engineering stone sculpture and landscape architecture,static load and dynamic load and personnel activities.By reducing the static load of the planting matrix,selection of light plants,optimization of landscape design and other methods can reduce the load bearing pressure on the roof.Four is the Roof garden waterproof,drainage,water saving.Waterproof is mainly related to the basic structure model,special location structure,deformation joints,such as waterproof structure.Drainage design includes gravity drainage and slope drainage.Water saving design includes rainwater utilization system and ecological cropping system.Xi'an City,"the space city set sail ICB" staff restaurant in Roof garden to the ecological,scenic beauty,recreation,as the principle of.The structural system of Roof garden mainly includes vegetation layer,planting layer,filter layer,drainage and water storage layer,anti root layer,sliding layer,structure layer and so on.Planting construction in the shrub and ground is mainly.In this paper,the construction of the project Roof garden,planting construction,load control,waterproof design and other issues are discussed in this paper.
