可踩踏草坪式斜坡种植屋面绿化技术研究——以通州市民中心屋顶绿化为例

Research on Greening Slope Roof Based on Centipedegrass——Examples of Green Roofs of Tongzhou Civic Center in Nantong

南通市通州市民中心在平屋面、缓坡屋面和陡坡屋面上做了草坪绿化。文章介绍了该项目在斜坡屋面部分的土壤防滑固定、浇灌、排水和草种类型选择等技术。利用防滑格将土壤分割成无数细小单元分散下滑力,并利用现有屋面结构特点增加防滑固定措施;采用根部浇灌,能让水分渗透进土壤,减少表层挥发;以排水为主、蓄水为辅,保证排水通畅的同时有效蓄水;在选择草种类型时,以可踩踏的平民假俭草成坪种植,交播黑麦草,保持四季常绿。该项目获得了2015年度鲁班奖。

Nantong Tongzhou Civic Center made the greenroof on flat roof, gentle slope roof and steep slope roof. This article introduces the techniques about stabilizing the soil on slope roofs, irrigation, drainage and lawn type selection. The non-slip grid divides the soil into numerous small units to disperse drop force and prevent slipping, and anti-skid measures are added by the existing roof structure. Root irrigation allows water penetrate into the soil and reduce surface volatile; the drainage-based and impoundment supplemented system can ensure smooth drainage and impoundment effectively. It chooses the civilian centipedegrass lawn and overseeding the perennial ryegrass. The project won the 2015 Luban prize.
