Internal Research On New Technologies Of Water Supply Drainage And Designs Of Residential Buildings Recently

With the development of residential industry and the improvement of people living level, the functions of conventional residential buildings do not meet people's needs any more, which leads to the application of many new design methods of residential buildings. As far as the water supply and drainage of buildings are concerned, these new developments include the reformation of water meter reading systems and drainage way of toilet and kitchen, the improvement of hydrant systems and automatic sprinkler systems, the application of drinking water systems. This dissertation will focus on these changes and deliver some summaries and discussions about them.(1) Water meter reading system In this chapter, the history of water meter installation and the outdoor water meter reading systems are introduced. IC water meter system, automatic meter reading system with individual collector and concentrator, automatic meter reading system with integration of collector and concentrator, radio reading system and their components, merits, shortcomings and scope of applications are discussed. The current situation and developing tendency of application of automatic meter reading system are analyzed. Some suggestions on management of automatic meter reading systems are put forward.(2) Drainage way'of toilet and kitchen of residential building In this chapter, the necessity of reformation of drainage way of toilet and kitchen are presented. Drainage way with floor blocked up, drainage with back outlet sanitary facilities and drainage with floor descended are discussed and summarized. A new drainage way with floor descended is introduced which solves the problem of seeper drainage.(3) Fire water supply systems of high-rise residential buildings In this chapter, the requirements on fire water supply systems of common high-rise residential buildings and of business-living buildings are compared. Fire water supply systems of high-rise residential buildings including their facilities installation of hydrant systems, water supply of sprinkler systems, sprinkler systems of garage and power room and reservoir designs are analyzed and summarized. Safe and economical systems are discussed as a reference to similar systems.(4) Residential sprinkler systems The history, system styles, water supplies, system components and requirements of design calculations of residential sprinkler systems are presented. The prospect of application of residential sprinkler systems isanalyzed. Some suggestions on residential sprinkler systems based on current economic conditions and developing tendency of residential industry are put forward.(5) Drinking water systems of high-rise buildings Treatment techniques and treatment processes of drinking water are summarized. Piping designs, water supplies, system calculations and selection of water pipe of drinking water systems are discussed. Some suggestions on management of drinking water based on current situation of drinking water are put forward.
