模块化管廊结构在危险品码头改造中的应用

为解决传统液体危险品码头改造中上部结构建设施工速度慢、施工质量难控制、施工安全风险高、经济性差等问题，进行了模块化管廊结构关键技术研究，首次将该结构应用于液体危险品码头改造中，提炼出模块化管廊结构设计与装配化施工过程中的尺寸控制、限位措施以及检测和纠偏措施等关键技术，并结合BIM技术进行施工过程管理。结果表明，该结构的应用可大幅缩短工期，减小施工期安全风险，提高工程质量，大大减小对已建码头营运影响，提升经济效益。

Application of modular pipe rack prefabricated structure in dangerous goods wharf renovation

To solve the problems of slow construction speed, difficult construction quality control, high construction safety risk and poor economy in the renovation of the upper structure of traditional liquid dangerous goods dock, the key technologies of modular pipe gallery structure are studied.The structure is applied in the renovation of liquid dangerous goods dock for the first time, and the key technologies such as size control, limit measures, detection and deviation correction measures in the structural design and assembly construction process of modular pipe gallery are extracted, and BIM technology is combined to manage the construction process.The results show that the application of this structure can greatly shorten the construction period, reduce the safety risk during the construction period, improve the quality of the project, greatly reduce the impact on the operation of the built wharf and improve the economic benefits.
