摘要
机翼形量水槽具有结构简单、操作简便、测量精度高、水头损失小等诸多优点,是农田水利及灌区灌溉管理迫切需要推广的技术之一,对于灌溉利用系数的提升具有重要意义。本文以室内模型试验为基础,对机翼形量水槽在矩形、梯形和U形渠道中的应用效果进行了对比分析,对于机翼形量水槽在农田水利及灌区节水灌溉中的推广使用具有借鉴意义。
Wing-shaped flume has many advantages,such as simple structure,simple operation,high measurement accuracy,small head loss,etc. It is one of the technologies urgently needed to be popularized in irrigation management of farmland water conservancy and irrigation districts,and it is of great significance for improving irrigation utilization coefficient. Based on the indoor model test,this paper compares and analyzes the application effects of wing-shaped flume in rectangular,trapezoidal and U-shaped channels,which has reference significance for the popularization and application of wing-shaped flume in farmland water conservancy and water-saving irrigation in irrigation districts.
