1、 1 翻译材料 The high-rise construction life gives the water way to the aqueous system the choice Abstract: Through the high-rise construction life for aqueous system each kind for the water way analysis comparison, thought the basis special details use the top digit water tank reduced pressure are quite

2、 economical reasonable give the water way for the water way or several kinds for the water way union in at present. Key word: The high-rise construction gives the water for the water way reduced pressure The choice for the water way is the high-rise construction life to the aqueous system design key

3、, it relates directly to the life gives the aqueous system the use and the project construction cost. Regarding the high-rise construction, the city cannot satisfy the high area partial domestic water generally for the water pipe network hydraulic pressure the request, the overwhelming majority uses

4、 the district for the water way, namely the low area are partial straight according to by the city for the water pipe network water supply, the high area partially pressurizes by the water pump the water supply. Speaking of the present our country city for the water condition, the hydraulic pressure

5、 may satisfiedly construct five six domestic water requests generally, the high area partial water supplies should act according to the special details determination. Construction Gives Water Draining water Design Standard (GBJ15 88) (Hereafter refers to as Standard)2.3.4Strip stipulation that,“The

6、high-rise construction life for the aqueous system vertical district, should act according to the operation requirements, material condition and so on equipment performance, service management, building layer, the union uses outdoor gives the water pipe network the hydraulic pressure reasonable dete

7、rmination. The district lowest health appliance matches the water drop place static hydraulic pressure, the housing, the hotel, the hospital is suitable is300 350KPa； The office building is suitable is350 450KPa。 ”Therefore, stipulated according to Standard the district for the water static hydrauli

8、c pressure, the proper attention to both fire prevention for the aqueous system for the water way, the high-rise construction life are partial for the aqueous system high area should carry on the reasonable vertical district. The city uses to be day by day anxious, urges the high-rise building to th

9、e upper air development, the modern science and technology and the modern industry development, also has provided the condition for the high-rise construction,20Century50Since the age, in the our country big city has constructed one batch of high-rise constructions one after another. Specially 2 80S

10、ince the age later our country will have implemented the reform and open policy, the economic development will change with each new day, the high-rise construction in the big or media-sized cities and even small town city like mushroom growth rising straight from the ground, the development will be

11、very quick. According to Shanghai2,002The year statistical count indicated the high-rise construction has reached5,000Yu Dong. The high-rise construction is saving with, the magnificent city and improves aspect the and so on people quality of life superiority has recognized as each person. The high-

12、rise construction fire fighting emergency is not easy to become now the fire to save goal“Three is difficult”One (“Three is difficult”Is refers to the high-rise construction, the underground project, the petroleum chemical industry three kind of fires), but the high-rise construction fire fire preve

13、ntion gives the water is the fire fighting foundation, also is difficult to be difficult. The high-rise construction although bases helps oneself, but falls behind helps oneself the system once to malfunction, or helps oneself the system although to be possible to work but cannot satisfy the use pot

14、ency, the fire fighting also must depend upon the fire brigade the motion facility and equips saves goal. The housing achievement supplies the family housing use the construction, is important place which the humanity must not be possible from bottow to top to lack. In the correct processing housing

15、 design meets the fire question, relates directly to peoples life and property safety. At the same time, a reasonable engineering design also needs to consider the items of basic construction the investment construction cost, achieves both safely is suitable, and the economy is reasonable. The high

16、area are partial the district which may use for the water way to include: The top digit water tank gives the water way； The frequency conversion velocity modulation water pump gives the water way for the water way or the barometric pressure pot. High level Civil construction Design Fire protection S

17、tandard (GB50045 95)7.4.7Strip stipulation that,“When uses the high pressure for the aqueous system, but does not suppose the top digit fire prevention water tank. When uses the temporary high pressure for the aqueous system, should suppose the top digit fire prevention water tank 。 ”Our country the

18、 fire prevention the temporary high tension system is in the majority at present for the aqueous system in, the general high-rise construction all is equipped with the top digit fire prevention water tank. Increases in not many situations in the top digit water tank dischargeable capacity, the life

19、water storage and the fire prevention store water at the same time stores in a water tank, this both the economy and is advantageous for the management. The top digit water tank has the constant voltage function, causes the cold hot water system hydraulic pressure maintenance balance, facilitates ta

20、kes a bath. The frequency conversion velocity modulation water pump cannot satisfy the fire prevention to store the water volume, has the small current capacity and the zero cur 3 rent capacity water supply question, at the same time the frequency conversion control stock price is high, uses few in

21、the high-rise construction. The barometric pressure pot is the barometric pressure pot adjustment volume is small for the water way main shortcoming, the similar existence cannot satisfy the question which the fire prevention stores water, the general achievement fire prevention for the aqueous syst

22、em in regular pressure unit, uses in generally regarding the high-rise construction life for the water time the minority floor hydraulic pressure insufficiency turbo-charged. Because above many reasons, the overwhelming majority high-rise construction uses the top digit water tank at present for the

23、 water way, although the top digit water tank existence increase construction load and prevented the domestic water receives the question which two time pollutes. The top digit water tank may according to Standard for the water way to request to use the top digit water tank reduced pressure for the

24、water way, the top digit water tank parallel for the water way or the top digit water tank series for the water way, or uses several kinds according to the special details to give the water way the union. Top digit water tank reduced pressure gives the water way use reduced pressure water tank and t

25、he pressure relief valve reduced pressure. The reduced pressure water tank takes the certain floor space, and increased had prevented the domestic water two time polluted the difficulty, had the noise influence. Pressure relief valve construction cost although high, but the area reduces greatly, doe

26、s not affect the water quality moreover not to have the noise, the domestic pressure relief valve product quality enhances, the performance is reliable, therefore selects the pressure relief valve reduced pressure method to increase day after day. The top digit water tank gives the water way in the

27、practical application to be possible according to the below situation consideration. 1.Construction altitude50mThe about high-rise construction, the high area are partial may use the tankWater pumpRoof water tankThe pressure relief v alve gives the water way. If the low area is partially high to the

28、 water supply safe request, may direct the next pipe riser directly from the roof water tank to the low area pipe network, on this pipe riser supposes the electrically operated valve and the pressure relief valve, usually the electrically operated valve closure, stops the water supply for the water

29、pipe network turns on the electrically operated valve when the city to the low area water supply. Like chart1Shows. This way water supply safe is reliable, fully has used the city pipe network hydraulic pressure, saves the energy. This way universal use. 2.Construction altitude50 80mThe about high-r

30、ise construction, the high area are partial may use the tankWater roof water tankThe pressure relief valve (sees the chart for the water way2) Or the top digit water tank parallel (sees the chart for the water way3) . Parallel for independent gives the aqueous system for the water way various districts, the water supply safely is reliable, water pump centralism arrangement, then management maintenance,
