Abstract:The infrastructure reconstruction of historical cultural blocks is always the difficulty and pain point in the reconstruction process. And the reconstruction of rainwater and sewage separation increases the difficulty in the implementation of rainwater and sewage separation reconstruction even more due to the shallow foundation of existing block buildings, the narrow blocks and the complex existing pipelines. Combined with the existing drainage system of the block, and aiming at the characteristics of the current terrain slope during the design of rainwater and sewage separation of the project, the different drainage systems are adopted according to the local conditions, and three different reconstruction strategies are proposed better to implement the reconstruction of rainwater and sewage separation, which not only achieves the collection and discharge of sewage, but also eliminates the waterlogging points for a long time in the block.
