沁水县李庄村小型农田管灌改造规划设计

Planning and Designing of Renovation of Irrigation Pipe in Small Farmland in Lizhuang Village of Qinshui County

在现代农业中,科学的灌溉方式对于作物产量的增加、经济的节约已经产生了不可或缺的作用。以晋城市沁水县胡底乡李庄村灌区改造工程为例,通过对当地水文地质条件理论分析与数据计算,对项目区水源及泵站工程进行了分析设计,得出了适合项目区的灌溉定额为54mm,灌溉周期15d,为满足灌溉要求应配出水量为50m3·h-1的大口井一眼,输水管道为110mm,选配3BA-6A型离心泵,额定扬程为41.5m,相应配套动力11kW电机。此设计既满足灌溉要求又节约成本,可为类似工程提供参考。

In the modern agriculture ,scientific irrigation methods has play an indispensable role on increasing crop yield and saving economy.In this paper ,by taking the reconstruction project of Irrigation District in Jincheng City ,Qinshui County ,Hu Di Xiang Li Zhuang Cun ,asan example ,and by analyzing thelocal hydrogeology theory and calculating the data ,the water source and pumping station project were analyzed and designed. The Suitable irrigation quota was45 mm ,the irrigation cycle was 15 d. To meet the requirements of the irrigation ,the output of 50 m3 · h - 1 open well should equipped with ,water pipe was 110 mm ,equipped with 3BA - 6A centrifugal pump ,rated head was 41.5 m ,with 11 kW motor power. This design satisfied the requirement of irrigation and saved cost d ,could provide a reference for similar projects.
