- Application of BIM Technology in Renovation and Expansion Project of a Municipal Wastewater Treatment Plant
- 摘要:
- 长沙市某污水处理厂一期（现状）规模为10×104 m3/d，二期改扩建工程建成后规模将扩大至19×104 m3/d，采用新型高浓度复合粉末载体生物流化床（HPB）+加砂高效沉淀工艺。针对改扩建工程存在的建设用地紧张、厂区地下管线复杂且迁改工程量大、单体数量多且结构形式复杂、工期紧张需合理排布时序等重难点问题，发挥BIM技术的可视性、优化性、模拟性等优势，制定全过程BIM实施规划。设计阶段通过Revit软件和二次开发工具完成厂区现状管线、三维地质以及BIM数据创建，基于模型校核多专业设计方案，提前发现问题，减少后期设计变更；并重点探究了Revit二次开发系统架构、代码调用方式和功能控制逻辑等，研究对比了不同格式实景模型与BIM模型的融合效果，以提高实景模型的材质稳定性，验证了Revit模型与计算流体力学（CFD）分析软件的数据交互可行性。施工阶段以BIM协同管理平台为核心，实现全厂多源模型数据集成、轻量化展示、云端更新，并集成场地布置模拟、管线迁改方案模拟、建设时序计划模拟分析等专项BIM应用成果，通过三维现场交底提高参建方协作效率，有效把控施工现场进度并辅助质量管理。
- Abstract:
- The current capacity of the phase Ⅰ project of a wastewater treatment plant in Changsha is 10×104 m3/d. The scale of the Phase Ⅱ expansion project will be increased to 19×104 m3/d after completion, and the novel high-concentration composite powder carrier biofluidized bed (HPB) along with a sand-enhanced high-efficiency sedimentation process will be adopted. In light of the significant and challenging issues presented in the project, such as the limited availability of construction land, intricate underground pipelines within the plant area, a substantial number of relocation projects, a large number of individual structures with complex structural forms, and a tight construction schedule necessitating a well-organized timeline, an all-encompassing BIM implementation plan was devised to fully leverage the benefits of BIM technology including visibility, optimization, and simulation. During the design stage, Revit software and secondary development tools were utilized to finalize the construction of the current plant pipeline, 3D geology, and BIM data. Multi-specialty design schemes were checked based on models in order to identify problems in advance and reduce later design changes. Additionally, there was a focus on exploring the architecture of the Revit secondary development system, code call mode, and function control logic. The study also involved comparing the fusion effect of different formats of reality model and BIM model to improve the material stability of the reality model. Furthermore, it aimed to verify the feasibility of data interaction between Revit model and computational fluid dynamics (CFD) analysis software. In the construction stage, the BIM collaborative management platform served as the core for achieving the integration of multi-source model data, lightweight visualization, and cloud updates for the entire plant. It also integrated specialized BIM application results such as site layout simulation, pipeline relocation plan simulation, and construction timing plan analysis. The participant collaboration efficiency was enhanced through three-dimensional on-site disclosure, effectively controlling construction site progress and assisting in quality management.
