深圳LNG应急调峰站取水口设计

Design of water intake for Shenzhen LNG emergency peak shaving station

根据深圳LNG应急调峰站取水口平面布置,结合其使用功能特点和施工过程,取水口结构采用与护岸同步施工。针对取水口结构尺寸大、质量过大、浮运安装比较困难的问题,进行针对性的结构设计,采取“预制浮坞式+现场二次浇筑”方案,并对不同工况下结构内力进行数值分析。结果表明,该方案能满足设计要求,较好地克服施工过程中遇到的困难,并顺利通过交工验收,达到了节约成本和缩短工期的目的。

Based on the layout of the water intake for the Shenzhen LNG emergency peak shaving station,combined with its functional characteristics and construction process,the water intake structure is constructed synchronously with the revetment.In view of challenges of the large size,excessive mass,and difficulty in installation due to floating transportation of the water intake structure,a targeted structural design approach is carried out.The“prefabricated floating dock+on-site secondary pouring”scheme is adopted,and numerical analysis of internal forces under different conditions is carried out.The results show that this scheme meets the design requirements.It effectively overcomes challenges encountered during the construction process and successfully passes the final inspection,achieving the goals of cost savings and shortened construction period.
