3、er supply and drainage; Design and construction; Sewage treatment 引言：隨著現(xiàn)代科學技術的不斷發(fā)展與人們生活水平的日益提高，人們對于現(xiàn)代住宅有著越來越多的要求，例如，需要更多的靈活性與適應性等。給排水的設計則是實現(xiàn)現(xiàn)代住宅靈活性與適應性功能的主要組成部分。Preface: with the continuous development of modern science and technology and the increasing of people's living standard, people have m

4、ore and more requirements for modern residence, for example, the need for more flexibility and adaptability, etc. Water supply and drainage design is to realize the modern housing flexibility and adaptive functions of main components. 一、建筑給排水設計思路A, building water supply and drainage design 1.1給水系統(tǒng)1.

5、1 water supply system 系統(tǒng)設計要為每幢住宅設一個獨立的給水系統(tǒng)，采用蓄水池水泵水箱減壓閥用水點的供給方式。它既能滿足市政基礎設施滯后于住宅建筑快速發(fā)展帶來的弊端，避免對市政給水管網造成沖擊；又能解決高層民用建筑設計防火規(guī)范中對消防前期貯水量的要求。System design for each house to set up an independent water supply system, adopting reservoir, water pump, water tank, pressure reducing valve, water supply mode. It

6、 can meet the municipal infrastructure lags behind that of residential construction rapid development will bring disadvantages, to avoid the impact of municipal water supply pipe network; And can solve the code for fire protection design of tall buildings on fire early in the reservoir capacity requ

7、irements. 1.2 消火栓給水系統(tǒng)1.2 fire hydrant water supply system 建筑滅火設計已成為建筑給排水設計的重要組成部分。在消火栓給水系統(tǒng)中更注重撲救初期火災，系統(tǒng)中才采用穩(wěn)壓泵保持系統(tǒng)的穩(wěn)高壓。在分區(qū)中可采用減壓閥、多出口水泵、穩(wěn)壓閥，以保證消火栓的水壓和出水量。為保證滅火設備能及時投入運行，設置工作泵和備用泵的自動切換裝置。Building fire design has become an important part of building water supply and drainage design. In the early fire

8、hydrant water supply system pay more attention to fighting, in the system only USES the voltage regulator to keep system stable high pressure pump. Pressure reducing valve can be used in the partition, many export pump, regulator valve, to ensure the water pressure of fire hydrant and water yield. I

9、n order to ensure the fire extinguishing equipment can be put into operation in time, set the working pump and standby pump automatic switching device. 二、給排水施工設計時應注意的問題Second, water supply and drainage construction design should pay attention to the problem 為了保證建筑給排水施工設計的質量及更有利于污水的排放和處理，在給排水設計施工時應注意

10、以下幾個方面的問題。In order to guarantee the quality of building water supply and drainage construction design and more conducive to sewage discharge and treatment, when the water supply and drainage design and construction should pay attention to the following several aspects. 2.1衛(wèi)生間管道的布置問題2.1 toilet pipe l

11、ayout problem 做好了衛(wèi)生間管道布置的好處在于檢修和疏通時，可避免影響下層住戶。但實際情況是當本層管道堵塞漏水時，積水往往造成下層住戶附近墻體被滲漏，反而擴大了影響范圍，而且在本層檢修要打鑿衛(wèi)生間地面，發(fā)生噪音，地面修補還要多工種協(xié)作，比較麻煩。還不如到下層衛(wèi)生間頂棚維修更省事。而且現(xiàn)在社會上管道疏通也方便，筆者認為無需大動干戈。Ready to piping arrangement is that the benefits of repair and dredge the toilet, can avoid affect the lower. Layer but the real

12、ity is that when the blockage is leaking, water tends to cause the lower resident near the wall is leakage, it expanded the scope, and in this layer maintenance to chisel ground toilet, noise, ground more repair work collaboration, more troublesome. Might as well to lower toilet ceiling maintenance

13、more convenient. And now society pipeline dredge is convenient, the author thinks that without fuss. 2.2排水管道同層敷設2.2 drain pipe installation tree 住宅設計規(guī)范規(guī)定：住宅的污水排水橫管宜設于本層套內，當必須敷設于下一層的套內空間時，其清掃口應設于本層套內。建筑給水排水設計規(guī)范規(guī)定：住宅衛(wèi)生間的衛(wèi)生器具排水管不宜穿越樓板進入他戶。這兩個規(guī)范均建議排水橫管盡量設于本層，即同層排水。同層排水，便于檢修和疏通，可避免影響下層住戶，而且只有排水立管穿越樓板，減少樓

14、板孔洞，杜絕衛(wèi)生間滲漏。"Residential design code" regulation: residential sewage drainage horizontal tube should be set within the layer set, when must be laying in the next layer of the internal space, the clean the mouth should be incorporated in the layer set inside. Specification for design of bui

15、lding water supply and drainage provision: residential sanitary ware of toilet drains should not cross the floor into his home. These two specifications are suggested cross drainage tube in this layer, as far as possible namely drainage. Drainage to facilitate maintenance and dredge, can avoid affec

16、t the lower household, and only water drainage riser across the floor, reduce the floor hole, prevent leakage of toilet. 2.3雨水排水系統(tǒng)與生活生產排水系統(tǒng)應嚴格分開2.3 rain water drainage system and production drainage system should be strictly separated 建筑給水排水設計規(guī)范說明中強調了雨水系統(tǒng)與生活生產排水系統(tǒng)設計計算方法的不同。雨污、雨廢合流將會影響生活、生產系統(tǒng)的正常運行。近幾

17、年隨著經濟的發(fā)展，群眾生活水平的提高，住房面積在增大，層數(shù)在增多，經常出現(xiàn)低層住戶排水口冒氣和溢水的情況，尤其是在排水管堵塞或半堵塞的情況下，使得房內的高檔裝修和貯放的物品浸水，造成經濟損失。Specifications for design of building water supply and drainage statement highlights the rain water system and drainage system design and calculation method of different life production. Dirt, rain, rain

18、waste confluence will influence the life and the normal operation of the production system. In recent years, with the development of economy, people living standard rise, the housing area is rising, the layer number on the rise, often appear lower household drain steaming and spilled water situation

19、, especially under the condition of the drain plug or half block, make the room of the high-grade decoration and storage items of flooding, causing economic losses. 2.4合理選擇排水管材2.4 choose the drainage pipes 隨著塑料管材的日益推廣，排水塑料管已在建筑高度100m以下的建筑物內廣泛使用，但建筑高度大于、等于100m的高層建筑和不適宜采用排水塑料管的場合，可采用柔性抗震排水鑄鐵管。With the

20、 increasingly popularization of plastic pipes, drainage pipes have been widely used in building height of 100 m below the building, but the building height is greater than, equal to 100 m in the high-rise building drainage pipes and inappropriate use of occasions, can adopt flexible aseismic cast ir

21、on drainage pipe. 排水塑料管的優(yōu)點：管道內壁光滑，阻力系數(shù)小，不易積垢，排水通暢，化學穩(wěn)定性好，耐腐蝕性好，導熱系數(shù)小，重量輕，安裝維修方便，外表美觀，易于粘接。但是，排水塑料管也有缺點：力學性能差，抗沖擊性差，剛性差，平直性差，阻燃性差，熱膨脹性系數(shù)大，管壁薄，隔音性能差。Drainage pipes: the advantages of the pipeline inner wall is smooth, the resistance coefficient is small, not easy to fouling, drainage unobstructed, goo

22、d chemical stability, good corrosion resistance, thermal conductivity is small, light weight, easy installation and maintenance, beautiful appearance, easy to glue. However, drainage tubes also have disadvantages: mechanical properties, impact resistance is poor, poor rigidity, poor laymen, flame re

23、tardancy, thermal expansion coefficient is large, thin wall, insulation performance is poor. 塑料管材雖然應用廣泛，但是還有許多問題值得探討，要求設計施工人員慎重行事，不僅要考慮優(yōu)點，同事還要考慮剛性、絕熱性、膨脹性，對多震地區(qū)還要考慮抗震性因素。塑料管因隔音性能差可選擇內壁帶螺旋塑料管、芯層發(fā)泡管或隔音空壁管等隔音塑料排水管材，可在一定程度上降低噪音。塑料管因熱膨脹系數(shù)高，特別作為熱水管可采用柔性接口，設置伸縮補償裝置。Plastic tubing although widely used, but

24、there are many problems worth exploring, request design and construction personnel to act prudently, should not only consider the advantages, colleagues consider rigidity, insulation, dilatability, consider earthquake-resistance factors to seismogenetic area. Selection of general sound-insulated per

25、formance plastic pipe inner surface with spiral plastic pipe, core layer foam pipe insulation or empty wall sound insulation plastic drainage pipes, can to a certain extent, reduce the noise. Plastic pipes due to thermal expansion coefficient is high, particularly as hot water pipe can be used in fl

26、exible interface, setting expansion compensation device. 三、關于給排水節(jié)水技術3, about the water supply and drainage water saving technology 3.1防止二次污染造成的水量浪費3.1 to prevent the secondary pollution caused by waste water 二次污染事故的發(fā)生，使得建筑給水系統(tǒng)不能正常工作，造成用戶用水困難。同時，受到污染的水將會被排放；對供水系統(tǒng)的清洗處理，也需耗費大量的自來水，這些都造成了水的嚴重浪費。因而防止建筑給水

27、系統(tǒng)二次污染，對節(jié)約用水有著十分重要的意義。Secondary pollution accidents, making the building water supply system can not work normally, causing the user water difficult. At the same time, the pollution of water will be discharged; Cleaning process for the water supply system, also need to spend a lot of water, which ca

28、used a serious waste of water. So to prevent secondary pollution, building water supply system for saving water has the very vital significance. 3.2大力發(fā)展建筑中水設施3.2 to develop the building water facilities “中水道”。顧名思義輸送的既不是上水道清潔的自來水，也不是下水道污穢的臟水。把一個地區(qū)居民洗臉、洗澡等洗滌水和沖洗用水集中起來，經過去污、出油、過濾、消毒、滅菌處理，輸入中水管網，以供從廁所、洗

29、汽車、澆草坪、灑馬路等非飲用水之用。用一立方米中水，等于少用一立方米清潔水，少排出近一立方米污水，一舉兩得，達到節(jié)水近50%。所以，中水道已在世界許多缺水城市廣泛采用。"ZhongShuiDao". As the name implies conveying is neither ShangShuiDao clean tap water, nor the sewer filthy dirty water. Put a district residents face and take a shower and washing water and rinsing water t

30、ogether, after decontamination, oil, filtration, disinfection and sterilization processing, input water pipe network, for the toilets, washing cars, watering the lawn, and sprinkle the road is not drinking water. Using a cubic meters of water, equal to a cubic meters of clean water, use less less ne

31、arly one cubic meter of sewage discharge, kill two birds with one stone, the water saving nearly 50%. So, ZhongShuiDao has been widely used in many cities around the world. 四、結束語Four, the conclusion 總之，建筑給排水的設計施工的應突出以人為本的原則，并將重點調整到民用建筑與工業(yè)建筑并重，公共建筑與居住建筑并重。在施工中統(tǒng)一管理，科學配置，這樣不僅能取得顯著的經濟效益，而且能在一定程度上緩解城市用水供需矛盾，取得較好的社會效益和環(huán)境效益。In sho
