Described water leg is that brick, inwall scribbles concrete cuboid.
Described cellular cover plate is concrete with honeycombed spots sheet material, and sheet metal thickness is 5cm, the aperture of honeycomb is 3cm.
The aperture of described nylon wire is 100 orders.
The thickness of described quartz sand layer is 5cm, the average diameter of quartz sand particle is 2mm.
The thickness of described gravel layer is 5cm, the average diameter of gravel is 1cm.
Described soil thickness is 10cm.
Described bottom width of catchmenting little Tu Gou be less than water leg upper wide, deeply for 5cm.
The bottom at the mouth of pipe two ends of described outlet pipe respectively with water leg bottom and inner edge, face, next stage terraced fields field in the same plane.
Face, every grade of terraced fields field is provided with water-distributing device, and described water-distributing device is connected with the outlet pipe of upper level terraced fields.
beneficial effect:face, the terraced fields field water-collecting irrigation facility that the application provides, has considered and has distributed feature that is uneven and existing terraced fields self structure in dry-hot valley rainfall season, automatically and fully collect storage precipitation, reduces water and soil loss, solves problem of water consumption in dry season; Do not need additionally to occupy cultivated land simultaneously, build cost low, safeguard simple, gravity irrigation, can be used as permanent installation and uses.
