摘　　要：介绍了为解决东雷抽黄灌区排沙存在难题而研制的自排沙廊道排沙技术,包括自排沙廊道的主要设施、设计原则、设计程序、结构要求、工作过程等。通过2004-2006年冬、春、夏8个灌季,在东雷抽黄总干渠上段运用测试,验证了自排沙廊道具有以下特点可小落差、“间歇”排沙;适应水流、泥沙、地形条件变化范围大;不消耗主体工程的水头能量;对主体水流的水深、流量、流速、流向等没有特殊要求;排沙、节水效果显著等。可广泛应用于各类渠道、河道、沉沙池、水库及其电站、引航道等工程的排沙。To remove the siltation and the bed load, auto-desilting technology has been applied in Donglei. From 2004 2006, after 8 irrigation periods＇ tests, we found the technique showed features as being small dropping variance, being ＂intermittence＂ discharge of silt; large adaptation range for water current, the silt, the topographical variation; not consuming the principal part of a project the water head energy; having no special request to the main body current of water depth, the current capacity, the speed of flow; which could widely used in channels, river courses, settling basins, reservoirs and power plants for desilting.
