装配式混凝土结构在竹园污水处理厂四期工程建设中的应用

Application of Prefabricated Concrete Structure in Construction of Zhuyuan Wastewater Treatment Plant Phase Ⅳ Project

竹园污水处理厂四期工程为新建120万m^(3)/d的污水处理设施及配套污泥设施,工程分为50万m^(3)/d和70万m^(3)/d两个厂区,为达到提高工程质量、缩短工期、减少环境影响等工程目标,同时突出技术创新的目的,工程中两个厂区生物反应池的缺氧区段采用了不同形式的预制装配技术。对工程中不同形式的预制装配技术进行介绍,并利用BIM技术对预制装配式结构从设计到施工进行全过程模拟,从工程的运输、吊装、受力体系以及功效等方面分析其优劣,总结预制装配式结构与现浇结构之间以及不同装配式结构之间的差异。期望通过竹园污水四期工程中装配式混凝土结构的实施,为我国污水处理厂装配式技术提供技术积累和工程经验。

The 1200000 m^(3)/d sewage treatment facilities and supporting sludge facilities are newly built in Zhuyuan Wastewater Treatment Plant Phase IV Project.The project is divided into two plant areas of 500000 m^(3)/d and 700000 m^(3)/d.In order to achieve the engineering goals of improving the engineering quality,shortening the construction period and reducing the environmental impact,while highlighting the purpose of technological innovation,the different forms of prefabricated assembly technology are used in the anoxic section of the biological reaction tanks in the two plant areas of the project.The different forms of prefabricated assembly technology in the project are introduced,and the BIM technology is used to simulate the whole process of the design and construction of prefabricated structure.The advantages and disadvantages are analyzed from the aspects of transportation,hoisting,stress system and efficacy of the project.The differences between the prefabricated structure and the cast-in-place structure as well as among the different prefabricated structures are summarized,which expects to provide the technical accumulation and engineering experience for the prefabricated technology of wastewater treatment plant(WWTP)in China through the implementation of the prefabricated concrete structure in Zhuyuan Wastewater Treatment Plant Phase Ⅳ Project.
