Study on Waterproofing Measures Optimization of Deformation Joints of Planting Roof--Taking Universal Studios Station of Beijing Metro as an Example.

The deformation joint is a weak link in roof waterproofing, especially for the shallow-buried basement roof planting or landscaping buildings with flexible waterproofing method. The deformation joints of roof have not become a mature and effective practice. Therefore, a deformation joint structure with high waterproofing reliability and landscape continuity is urgently needed. By taking Beijing Metro Universal Studio Station as an objective for research and implementation, this paper analyzes the applicability and limitations of different deformation joint structures. On the basis of research conclusions, the deformation joint structure is optimized and an interlocking deformation joint structure suitable for planting roof is formed, The structure, provided with multiple waterproof and drainage measures, is highly reliable, and it solves the problems of high maintenance difficulty and poor landscape effect in the conventional practice, and can be widely used in roof engineering.
