摘　　要：近年来,在长江航道整治工程实践中已证明了透水框架具有良好的促淤效果,逐渐成为航道整治工程中不可或缺的工程构件。针对长江干线武汉—安庆段6 m水深航道整治工程高强度的框架预制需求,且先后受到2019年底的水位回落异常情况、2020年初新冠疫情影响,透水框架预制进度严重滞后,采用拼装式模具代替整体式模具进行预制,并从预制件成品质量、构件脱模时间以及施工成本等方面进行对比分析,进而形成高质量、低成本、高效率的透水框架预制工艺,也缩短了后续水上抛投作业工期,最大程度地减少施工期对环境的影响。In recent years, the practice of the Yangtze River channel regulation project has proved that permeable frames can well promote siltation and have thus gradually become an indispensable engineering component in this channel regulation project. The 6-meter-deep channel regulation project in the Wuhan to Anqing section of the Yangtze River trunk line has an intensive demand for frame prefabrication. Moreover, the prefabrication progress of permeable frames is far behind schedule due to the abnormal drop in water level at the end of 2019 and COVID-19 at the beginning of 2020. For the above reasons, this paper replaces the integral molds with assembled molds for prefabrication and conducts a comparative analysis from three aspects, namely, the finished product quality of prefabricated components, the demolding time of components, and the construction cost. It further presents a permeable frame prefabrication process with high quality, low cost, and high efficiency. In this way, the paper also shortens the construction period of subsequent throwing operations on water and minimizes the impact of the construction period on the environment.
