Study on Drainage System that Enables Free Planning of Water Circulation

这项研究建议在建筑物中安装一种混合排水系统，将使用废水重力流的传统重力式排水系统与使用排水水泵等的机械排水系统相结合，以增加规划水循环空间的灵活性。具体地说，本研究讨论了上述排水系统排水性能的评估方法和设计方法，特别是当该系统应用于公寓楼和商业建筑时，考虑到水循环空间，例如用于可能新建或翻新的节水型厕所。

This study proposes a hybrid drainage system to be installed in buildings, which combines a conventional, gravity-type drainage system using the gravity flow of wastewater and a mechanical drainage system using a drainage pump, etc. to drain by force, with the intention of increasing flexibility in planning the space for water circulation. To be more specific, the study discusses a method for evaluating the drainage performance of the aforementioned drainage system and a method for designing same, particularly when the system is applied to apartment housing and buildings for business use, in consideration of water circulation spaces, for water-saving toilets for example, which may be newly added or renovated.
