建筑排水水封抗负压性能初步研究

Preliminary study of the water seal to resist negative pressure performance in building drainage system

水封是建筑排水系统常用的装置,本文通过实验研究,建立水封比,水封液面高度、击穿压力和击穿后水封剩余高度之间相互关系,为合理设计建筑排水系统水封装置提供了可靠依据。

Water seal is commonly used for drainage system of building.This paper through the experiment research,establishmenting of the relationship among the water seal proportion,the water liquid levels,breakdown pressure,the water liquid levels after breakdown,provides a reliable basis for the rational design of building drainage systems water seal device.
