本报告包括运输和浇筑混凝土用输送带的早期发展简史；与塑性混凝土性能、输送速率和工作规范相关的输送机系统设计；以及适用于特定现场要求的皮带宽度、速度和倾角。还讨论了三种类型的混凝土输送机（便携式、给料机和撒布机类型）及其特殊应用；输送机选择、使用和维护的现场实践；以及带式输送机布置的经济性。还强调了现浇混凝土的质量和检查程序。

This report includes a short history on the early development of conveyor belts for transporting and placing concrete; the design of conveyor systems in relation to the properties of the plastic concrete, the delivery rate, and the job specifications; as well as belt widths, speeds, and angles of inclination as they apply to specific site requirements. Also discussed are the three types of concrete conveyors (portable, feeder, and spreader types) and their particular applications; field practices in the selection, use, and maintenance of conveyors; and the economics of belt conveyor placement. The quality of the in-place concrete and inspection procedures are also stressed.
