渠系工程是农田水利基本建设中一项不可缺少的工作。渠系布置好坏,对于充分发挥机电排灌设备作用,合理用水,节约用电,对于降低工程造价,减少土地损失以及农业机械化,农村交通,积肥运肥关系很大。特别是,近年来在农业学大寨群众运动的推动下,为了从根本上改变生产条件,一些社、队结合长远发展规划实施地下渠道。由于地下渠道是一种永久性水利设施,一次化工多,投资大,布置是否适宜,影响到灌区的长远发展,因此更显 Canal system project is an indispensable task in farmland water conservancy construction. Drainage system is good or bad, for giving full play to the role of mechanical and electrical drainage equipment, water use, saving electricity, for reducing project cost, reduce land loss and agricultural mechanization, rural transport, fertilizer a great relationship. In particular, under the impetus of the mass movement of learning Dazhai in recent years, in order to fundamentally change the conditions of production, some communities and teams have implemented underground channels in combination with long-term development plans. Since the underground channel is a permanent water conservancy facility, it is more obvious that a large chemical industry, large investment and proper arrangement will affect the long-term development of the irrigated area
