The Design And Discussion Of Building Water Supply And Drainage In The District B District Of Xuzhou

In recent years,the rapid expansion of cities in our country,high-rise buildings and explosion going,landmarks,and more and more high-rise buildings,however,internal structure and layout of the space is more and more high-rise buildings more and more complex,the number of layer design,building height is becoming more and more high,at the same time,the limitation of the fire fighting equipment and rescue is difficult,so the high-rise buildings in building water supply and drainage and fire fighting design difficulty is becoming more and more big.A batch of new specification update and implementation of the requirement of increasing the various aspects of the building and requirements for the level of design staff is improved,especially the implementation of the new fire code,fire water and fire hydrant system research in China are summarized,the manufacture,design and maintenance and management of scientific research and engineering practice experience,make the fire protection system will be improved.In green building technology and water saving and energy saving in our country at the same time make a higher request,the green design of civil buildings "and" green building evaluation standard "launch and implementation,for new and renovation project design requirements to the greatest extent to achieve energy saving,water saving,material saving,land and environmental protection objectives,at the same time for the sustainable development strategy and the implementation of the people-oriented idea has a positive meaning.The main technologies of this study include:rainwater collection and recycling,full-flow high-efficiency variable frequency regulation and water supply technology,secondary water supply front technology,etc.Through the design and in-depth study of this project,a systematic detailed process design and in-depth exploration of the good domestic business city is carried out.The main content includes detailed design and calculation of the construction drawings of each independent system.The various systems of the construction drawing include floor plan and system diagram of water supply and drainage of life and fire.The calculation mainly includes water supply,drainage and other hydraulic calculation of life and fire fighting.In this paper,some measures of rainwater collecting system and water-saving energy saving are discussed in this paper.It can be seen that rainwater collection system is an important technical means for saving energy and saving energy.Finally studied the minimum effective fire-fighting pool water level control and voltage stabilizing pump of pump pressure computing research,through for the present analysis of several kinds of pool water dispute,I think the pump elevation drop plate is lower than the elevation of fire pool 1 meter.This can reduce the water level of the pool and reduce the area of the sink.This is more reasonable.By new and old specification comparison method of analysis of voltage stabilizing pump up the pump pressure,the design of the voltage stabilizing pump pressure value by the fire control system were calculated using the minimum working pressure(P1)shall prevail P2 value,can also by the pressure switch in high work pressure value of the voltage or the most unfavorable position and system of water pump water fire extinguishing facilities of the elevation difference(delta H)+ 0.15 MPa calculation.
