附录4 外文原文 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 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, 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 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 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 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 determination. 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 suitab
