中储粮洪洞直属库屋顶分布式光伏发电项目防水技术介绍

Introduction of Waterproofing Technology for Roof Distributed Photovoltaic Power Generation Project of Hongdong Directly Warehouse of Central Storage Grain

中储粮洪洞直属库屋顶分布式光伏发电项目在深入研究屋面防水要求与光伏组件安装的基础上,采用现浇支架基础但不破坏防水整体性的方案施工。具体做法是在防水层施工完成后在需要设置条形基础的部位做防水附加,然后浇筑条形基础。这样既避免了光伏安装完成后的荷载计算,又避免了对防水的破坏,保证了粮库防水的可靠性。

On the basis of depth study on roof waterproofing requirements and installation of photovoltaic components, the program of using cast-in-place stent foundation but does not undermine the integrity of waterproofing is applied for distributed photovoltaic power generation project of Hongdong Directly Warehouse of Central Storage Grain. After the construction of waterproofing layer is completed, waterproofing additional layer is installed at the areas needed to set strip basis, then the strip foundation is poured. These will not only avoid load calculation after PV installation, but also avoid the damage to waterproofing layer, and these ensure the reliability of waterproofing.
