自由曲面坡屋面种植技术初探--以北京地铁7号线环球影城站屋顶绿化为例

A Preliminary Study on the Planting Technology of Free Form Slope Roof--Taking the Roof Greening of Universal Studio Station of Subway Line 7 in Beijing as an Example

北京地铁7号线环球影城站屋面呈曲面型连续变化坡度的自由曲面坡屋面,设计种植屋面,必须将自由曲面坡屋面绿化的排蓄水和过滤技术、种植技术、防滑固定等关键技术加以整合。本项目采用建筑屋面防水保护层预埋式n型钩结构固定和生态种植袋叠设,形成一体化的预埋式约束系统,从而解决了传统屋面绿化施工工序繁琐、施工难度大、灵活性差等实际问题,实现了生态优先、兼顾景观,既降低种植屋面造价、又保证建筑结构安全的设计目标。

The roof of the Universal Studio Station of Beijing Subway Line 7 is a free-form curved slope roof with continuously variable slopes. The design of planted roof must integrate water drainage, storage and filtering technology, planting technology and anti-skid fixation, and other key technologies for free-form curved slope roof greening. This project adopts the embedded n-hook structure of roof waterproofing protective layer and ecological planting bags to form an integrated embedded restraint system, so as to solve the practical problems such as cumbersome construction process, difficult construction and poor flexibility of traditional roof greening construction, realize the design targets of ecological priority and give consideration to the landscape, cost reduction for planted roof construction, and building structure safety.
