Research On Ecological Water-saving Construction Technology Of Residential Buildings In Guanzhong

The shortage of fresh water resources is becoming more and more serious in China.The water resources in the northwest area only account for 10% of the whole country.There are three seasons of drought and summer rainstorms in Guanzhong,which result in uneven spatial and temporal distribution of rainfall and lack of water resources in general.In the context of rapid urbanization development,the spatial form of residential buildings presents a trend of centralization,and rainwater sewage discharge presents a trend of rapid pipeline discharge.Problems such as unreasonable use of rainwater in residential buildings,destruction of hydrological cycle,and lack of systematic water-related infrastructure are increasingly prominent.The contradiction between development and environment is increasingly intensified,and water-saving action is imminent.In order to alleviate this contradiction,the research on ecological water-saving construction technology of Guanzhong dwellings is particularly important.This article is based on the concept of sustainable development,to the guanzhong residence as the research object,from the perspective of human settlement environment science,comprehensive professional knowledge fields,such as architecture,water supply and drainage,through literature search,field observation and measurement data form wading present situation analysis,from the traditional ecological water-saving modern applications and modern wisdom general localization of water-saving technology two aspects proposed solution,finally based on the typical household has both houses into ecological water-saving design practice,integration and put forward ecological water saving technology,applied above build local-style dwelling houses of local ecological water cycle,optimize the design of the guanzhong residential water saving for the future reference.This paper carries out research from the following aspects:Chapter One: Asking Questions.The introduction introduces the research background and significance,research status at home and abroad,research content and purpose,research methods and framework of this paper.Chapter 2: Analyze the problem.According to the characteristics of rainwater utilization in different periods,it can be divided into two types: water self-balance digestion mode and pipeline priority drainage mode.Secondly from the status quo,drainage condition,storage with water status,and the present situation of the ecological wading water saving status quo five aspects detailed analysis,summed up the water cycle efficiency low,lack of the drainage layer,water storage performance degradation,poor durability of wading location,ecological water-saving efficiency is low,put forward the guanzhong residential water conservation design goal and the research train of thought.Chapter Three and Chapter Four: Problem Solving Idea I.Extraction and modern application of traditional ecological water-saving wisdom.Based on the analysis of ecological water-saving construction technology of traditional dwellings in Guanzhong,five water-saving design concepts of buildings are summarized,including the concept of recycling and multi-purpose water use,the concept of drainage of step by step water collection,the concept of water storage of priority water collection,the ecological concept of water microcirculation,and the concept of water-saving of water self-balance.Because of complicated demand change,the centralization of the spatial layout changes,when we adopt traditional ecological water-saving wisdom not blindly imitate,but should be guided by its response to drought,analyze the contradiction between its and modern construction point and its application to the modern,explore the traditional ecological water-saving wisdom and the ways and methods of modern residential combination,make its coruscate gives new vitality.Chapter Five: Problem Solving Idea II: Localization Adapting Design of Modern General Water-saving Technology.Analysis the guanzhong guanzhong residential ecological water saving construction intrinsic demand,the rain flood management thoughts,such as low impact development of modern general water saving technology localization,from water,drainage,water storage,ecological wading and water saving five aspects to explore the combination of ecological water conservation construction and residential,optimizing construction wading,wading cycle of systemic and continuity.Chapter 6: Design Practice.To establish the ecological water-saving overall circulation system inside the folk dwellings,to apply the ecological water-saving technology in Chapter 4 and Chapter 5,to integrate it with the folk dwellings,to put forward a complete water-saving design scheme,and to make a graphical analysis of the key points of improvement.Chapter 7: Conclusion.Finally,the research results of this paper are summarized.Building water-saving is an important part in the development of green building and ecological technology investment is lesser,great potential and good prospects,which saves water resources,upgrade the quality of life of farmers,to create the ideal ecological residential space,the traditional houses in guanzhong plain ecological water-saving experience the scientific mechanism of tradition and modern application,realize the residential ecological water saving performance optimization,improve the rural environment has a certain significance.
