二、引流工程 引流工程是把集流场的集水导流入农田或蓄水设 施。一般是修建引流沟连接集流面和蓄水设施,引流沟 的规格根据集水流量来确定。 引流沟是连接集水区和蓄水设施的纽带,作用是 把集水区的水输送到农田或蓄水设施。在工程设置上 需具有两种功能:首先把集水区截集的降雨径流通过 引流沟平稳有序的引入农田,以增加旱地农田的自然 降雨量,实现旱地农田雨水最大程度的集蓄;其次把降 雨径流引入蓄水设施贮蓄起来。所以引流工程担负着 引流贮蓄和沿程分水的功能。
Second, the drainage works Drainage project is the diversion field diversion into the farmland or water storage facilities. Drainage ditches are generally used to connect the collector surface and the water storage facilities. The specifications of the drainage ditches are determined according to the catchment flow. Drainage ditch is a link between the catchment and the water storage facilities, the role is to catch the water to the farmland or water storage facilities. There are two functions to be set up in the project: firstly, the catchment runoff collected by the catchment area is introduced into the farmland smoothly and orderly through the drainage ditches so as to increase the natural rainfall of the farmland in dry land and achieve the maximum accumulation of rainwater in the farmland; secondly Introduce rainfall runoff into storage facilities to save. Therefore, the drainage project is responsible for the drainage and storage along the water diversion function.
