Roof structure giving consideration to greening and photovoltaic power generation and construction method thereof

According to the roof structure giving consideration to greening and photovoltaic power generation and the construction method of the roof structure, the principle that desert photovoltaic power generation and sand greening coexist is used for reference, a photovoltaic power generation device is arranged on the roof for power generation, and meanwhile roof remaining space is fully utilized for roof greening; various roof greening structural forms are provided, multiple problems of puncture water prevention, water drainage, wind prevention, roof runoff water quality purification, convenient maintenance, solid waste utilization and the like are considered at the same time, and the technical effects of slowing down air and solid waste pollution, noise exceeding standards, urban waterlogging, heat island effect and the like are achieved while green electric energy is obtained. 本发明提供一种兼顾绿化和光伏发电的屋顶结构及其施工方法，发明通过借鉴沙漠光伏发电与沙地绿化共存的原理，利用屋顶设置光伏发电装置进行发电的同时，充分利用屋顶剩余空间开展屋顶绿化；发明提供多种屋顶绿化结构形式，同时考虑了穿刺防水、排水、防风、屋顶径流水质净化、便于维护、固废利用等
