峡谷中碾压混凝土高坝的混凝土运输入仓是施工的关键问题，江垭大坝混凝土运输以适应峡谷地形和碾压混凝土特性为主要特点，在施工中采用了自卸汽车、深槽式高速皮带机、负压溜槽和门机等多种方式组合的运输方案，成功地完成了大坝混凝土的运输。其中深槽式高速皮带机和负压溜槽联合输送系统，运用效果十分显著。施工实践表明，深槽式高速皮带机和负压溜槽都是经济高效的运输工具，值得广泛推广应用。
The concrete transportation and warehousing of the RCC dam in the canyon are the key issues in construction. The concrete transportation of the Jiangya dam is mainly characterized by the topography of the canyon and the properties of the roller compacted concrete. Dump cars are used in the construction. Belt machine, negative pressure chute and door machine and other ways combined transport solutions, the successful completion of the dam concrete transport. One deep groove high-speed belt conveyor and negative pressure tank joint delivery system, the application effect is very significant. Construction practice shows that the deep groove high-speed belt conveyor and negative pressure chute are both cost-effective transportation tools and worthy of wide application.
