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 k

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 us

Speaking of the present our country city for the water condition, the hydraulic pressu

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 hydra

9、the 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. Specially80Si

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-r

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 pote

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 ar
