北京新机场主航站楼采光顶、天沟防水技术分析

Waterproofing Technology Analysis for Lighting Roof and Gutter of the Main Terminal of Beijing New Airport

北京新机场项目采光顶外形变化多样、系统构造复杂,且与排水天沟相互衔接,其防水设计遵循"从原理出发,结合材料特性,防水与排水相结合"的基本理念,以"完全密封"为基础,局部辅以"收集储存"的主动防水方式,取得了较好的防水效果。本文着重介绍了该屋面天沟的防水做法,并对各系统防水重难点进行了分析。

The shape of lighting roof of Beijing New Airport Project varies widely and the system structure is complex,at the same time,it is connected to the drainage gutter.Its waterproofing design follows the basic concept of"starting from principle,combining with material characteristics,combining waterproofing and drainage",based on"completely sealed"and partially supplemented with"collection and storage"active waterproofing method,which achieves better waterproofing effect.This article focuses on the waterproofing method of the roof gutter,and analyzes the waterproofing difficulties of each system.
