城市建筑屋顶雨水资源绿化利用的防水安全设计

摘要

本次设计针对山西省太原市某教学楼种植屋顶的雨水资源利用，进行了结构安全设计。设计根据城市建筑物屋顶容易集雨的特点，通过对太原市降雨的基本参数的搜集计算，对其屋顶结构层进行了设计。设计内容包括了屋顶绿化种植层设计、过滤层设计、排水层设计、防水层的设计以及雨水回用方案设计等。同时重点对雨水资源化时建筑物顶的防水安全以及可能对建筑物造成不安全的隐患进行安全防护设计。此外，还对其防水层的施工技术要点和该建筑屋顶的载荷安全的校核，保障该建筑屋顶绿化对雨水利用过程中的防水安全。

The waterproof safe design of city construction roof afforestation used in rain water resources recirculation

Adsract

This design has done a structure safety system according to the reuse of the rainwater on the green roof of a teach building in Taiyuan, Shanxi province.This article designed its strucrure composition which based on the trait of easily gathered rainwater of the building roof in cites, it also based on the collection and calculation of the fundamental parameter of the rain fail in Taiyuan. The design content has included the design of the roof afforestation plant, the filter bed, the drainage layer, the waterproof layer as well as the rain water recirculation project and so on. Simultaneously this passage has put an emphasize on the safety protective design according to the waterproof of the building roof as well as possibly the hidden unsafe danger that could be created to the building during the recirculation of the rain water. In addition, its waterproof layer construction technology main point and this building roof load security has been checked to make the building roof reach the waterproof security in the rainwater reuse process.

Key words: rainwater reuse, waterproof security, water proof layer, roof afforestation
