摘　　要：介绍了渠灌区管道输水灌溉简况,提出了渠灌区半封闭式管道输水灌溉系统自水源、拦污栅、闸门、通气孔、管道、量水装置、安全与保护装置、分水减压池、浮子阀、田间给水栓等一整套工程解决方案,通过建设半封闭式管道输水灌溉示范工程和现场试验观测,验证了该种管道结构形式的适用性并取得了相关工程技术经验,为渠灌区开展自压管道输水灌溉工程提出了可供借鉴的技术模式。建议渠灌区宜采用中低压的自压管道输水灌溉系统,主干管宜采用开敞式结构,支管宜采用半封闭式结构,并应适时制定渠灌区管道输水灌溉工程技术规范。The pipe conveyance irrigation system in the canal irrigation district is described in this paper. A set of engineering solu- tions for semiTelosed pipe conveyance irrigation system in canal irrigation district is also proposed, including water source, trash racks, gates, vents, pipelines, water measurement devices, safety and protection devices manifold vacuum tank, the float valve, field hydrant, etc. By building a pilot project of semi-closed pipe conveyance irrigation system and testing observations, its applica- bility is verified, some engineering experience is obtained, and the referenced technical model for canal irrigation district is provided. It is proposed that the middle and low pressure system should be used in canal irrigation system, the open-structure type should be a- dopted for the main pipeline, the semi-enclosed structure model should be adopted for the branch pipeline, and the technical specifica- tions should be drawn up for the pipe conveyance irrigation projects in the canal irrigation district.
