随着现代化城市的迅速发展,城市的建设逐渐向私密性、舒适性和美观性方向发展,同层排水技术是近年来我国引进外国的先进排水系统进入到中国城市建设当中的。在我国许多先进城市的高中档住宅设计中同层排水受到广泛应用,作为传统的隔层排水技术则是备受冷落,在日本和欧美国家应用广泛的排水技术其实也存在一些问题,合理科学的排水技术需要同层排水和隔层排水的结合。由于我国经济发展迅速,大量大型的新兴建筑建设起来,以人为本的精神观念需要我们不断革新对传统住宅所出现的问题进行优化解决。同层排水和隔层排水作为在我国建筑排水建设中应用最为广泛的排水系统都应该通过不断优化的手段更好地为城市和农村建设服务。 相似文献

2009年版的《建筑给水排水设计规范》引入"最大设计排水能力"的概念,与近年来进行排水能力测试的"最大排水能力"构成了立管排水能力的两个重要概念,同时衍生出了很多相关的概念。为了便于设计人员了解各种概念的定义,抓住概念本质上区别,更好地指导工程设计,本文就建筑排水立管排水能力的若干概念进行辨析。 相似文献

Present firesafety measures were conceived to deal with hypothetical fires spreading by destruction of successive compartment boundaries. A new firesafety system, referred to as the fire drainage system, is designed to cope with real-world fires spreading mainly by convection. It confines fire and smoke to the room of origin and to a small corridor element adjacent to the room. The system can be designed to operate without the use of water and electric energy. The fundamentals of its design are described and some experimental information is presented.

This study was dealt with clogging problems of the drain aperture in old tunnels. The precipitates in the drainage were mainly generated by degradation of the tunnel concrete lining. The degradation was made by the chemical reaction between the concrete material and groundwater. If the degree of precipitation is high in the tunnel drainage, the groundwater cannot flow easily in it. Consequently, the groundwater level will go up, and this can lead to the highest water pressure which affects to the structural risk of tunnel. The degraded drainage causes to generate not only the structural stability of tunnel, but also the additional maintenance problem. Up to this time the technical study of preventing the scale for just tunnel drain aperture was rare. However, there are some preventive technologies about the scale for the industrial facilities such as oil pipe lines etc. There are two most popular technologies. One is Quantum Stick using Brown’s principle of quantum mechanics and the other one is Magnetizing device to inhibit the scale formation by changing the form of calcium carbonate particles. In this study, in order to improve the clogging problem in the tunnel drain aperture the elementary technologies were introduced. In addition, the laboratory tests were conducted to evaluate their applicability using the results from SEM and XRD analysis on the sediment generated during the test. As a result, Quantum Stick showed the reasonable effect of scale removing under the condition of more than velocity limit. 相似文献
