港口码头的主要生产活动,是组织和进行车、船装卸和货物的堆存、保管、计量以及收发等工作。其装卸方法通称为装卸工艺。合理的装卸工艺是增加港口通过能力,提高装卸效率,降低装卸成本,加速车、船周转,缩短货运期限, 提高货运质量,减轻劳动强度和改善劳动条件的重要物质基础和技术条件。因此,作为港口必须高度重视装卸工艺工作。特别是一些使用条件有特殊要求的港口,如码头桩基结构允许荷载较小,货种又纷杂时,尤 The main production activities of the port terminal are to organize and carry out the work of stocking, keeping, measuring, receiving and dispatching of vehicles, ships and cargoes. Its loading and unloading method is commonly known as loading and unloading process. Reasonable loading and unloading process is to increase the port capacity, improve handling efficiency, reduce handling costs, speeding up vehicles and vessels turnover, shorten the period of trucking, improve cargo quality, reduce labor intensity and improve the working conditions of the important material basis and technical conditions. Therefore, as a port must attach great importance to the loading and unloading process. In particular, some conditions of use have special requirements of the port, such as the pier pile structure allows less load, when the goods are mixed, especially
