排水立管设计的若干问题探讨

ON DESIGN OF DRAINAGE STACK

在《建筑给水排水设计规范》规定的参数范围内,通过对排水立管的计算,绘制了工程设计中常见的卫生器具配置模式下的立管选用表.从理论计算、设计、施工和造价等方面对单立管和双立管排水系统进行了比较,并且对卫生器具水封高度、支管接入立管配件选用等问题作了探讨.

Within the range of parameters required by the Design Norm of Water Supply and Drainage of Buildings a selection table of drainage stack for various apparatus common in engineering design has been provided by means of hydraulic calculation of drainage stack. The drainage systems with single and double stack were compared from the view of theoretical calculation, design, construction and cost. And the altitude of siphons and the fittings to connect to the stacks of apparatus were discussed.
